PREFACE

This report is an interim product of a joint effort of the Department

of Health, Education and Welfare (HEW) and the National Bureau of Standards (NBS), Center for Fire Research. The program is a five-year activity

initiated in 1975. It consists of projects in the areas of: decision

analysis, fire and smoke detection, smoke movement and control, automatic extinguishment, and behavior in institutional populations in fire

situations

.

This report, prepared by the Design Concepts Section, developed a methodology for generating an equivalency system for a specific fire

safety requirement and a specific example for a system which provides

equivalency to the minimum life safety requirements for the health care facilities as prescribed by Life Safety Code 101-1973.

A SYSTEM FOR FIRE SAFETY

EVALUATION OF HEALTH CARE FACILITIES

H. E. Nelson and A. J. Shibe

Abstract

A quantitative evaluation system for grading

health care facilities in terms of fire safety is

described. The system can be used to determine how

combinations of widely accepted fire safety equipment and building construction features may provide

a level of safety equivalent to that required by

the widely accepted Life Safety Code of the National

Fire Protection Association. The system will provide

flexibility to both the designer of new facilities

and to the renovator of existing health care facilities.

Three major concepts form the basis for code

equivalency

:

a. Occupancy Risk - the number of people

affected by a given fire, the level of

fire they are likely to encounter, and

their ability to protect themselves.

b. Building Safety Features - the ability

of the building and its fire protection

systems to provide measures of safety

commensurate with the risk.

c. Safety Redundancy - in-depth protection,

through the simultaneous use of alternative

safety methodologies such as containment,

extinguishment, and people movement

methodologies. The design of the complete

fire safety system is intended to ensure

that the failure of a single protection

device or method will not result in a major failure of the entire system.

In this system, e quiva

v

is judged to exist when

the total impact of the occl^cu y risk factors and the

compensating building safety features produce a level

of safety equal to or greater than that achieved by

rigid conformance to the explicit requirements of the

NFPA Life Safety Code. In this evaluation, safety

performance is gauged both in terms of overall safety

impact and depth of redundance.

1. INTRODUCTION

The ideal goal of life/fire safety design is to prevent all fire

deaths, injuries and losses under all imaginable circumstances. Practically, however, society can neither forestall all loss of life nor spend

limitlessly to avert loss of life due to fire. Building codes are designed to provide a minimum acceptable level of life safety at a cost

society is able and willing to support. The Life Safety Code of the

National Fire Protection Association (NFPA No. 101) is a voluntary code

widely accepted for setting acceptable fire safety levels. The code

provides fixed solutions for life safety in designated occupancies, but

allows "equivalent" solutions. However, it does not define alternative

solutions nor provide a mechanism for evaluating equivalence.

The Center for Fire Research with support from the Department of

Health, Education and Welfare has developed a system for determining how

combinations of widely accepted fire safety systems and arrangements may

provide a level of safety equivalent to that required in the 1973 Life

Safety Code. The system provides flexibility to the designer of new

facilities and to the renovator of existing health care facilities.

The major concepts forming the basis for code-equivalence are:

a. Occupancy Risk - the number of people affected by a given

fire, the level of fire they are likely to encounter, and

their ability to protect themselves.

b. Building Safety Features - the ability of the building and

its fire protection systems to provide measures of safety

commensurate with the occupancy risk.

c. Safety Redundancy - in-depth (redundancy) protection, through

the simultaneous provision of alternative safety methodologies

such as containment, extinguishment, and people movement

methodologies. Each methodology provides at least its own independent minimur . cJe level of protection. The design of

the complete fire safety system is intended to ensure that the

failure of a single protection device or method will not

result in a major failure of the entire system.

An adequate life safety system must include a building safety

system commensurate with the occupancy risk. The Fire Safety Evaluation

System provides a model for evaluating the fire risk in a building, by

incorporating factors such as mobility of people, number of people at

2
risk, height of building, etc. The calculated risk level provides a minimum target for which levels of protection must be provided by the

nature of the building design supplemented by appropriate passive and

active fire protection devices.

The evaluation system is also a technique for obtaining a quantitative measure of the level of safety provided by a protected building.

This level is determined from an evaluation of the various construction

elements and fire protection features. The system measures both the gross

level of safety and a set of safety subsystems related to containment,

extinguishment and people movement. These subsystems are individually

graded to evaluate the depth of redundancy in the building fire safety

system. The evaluation system is a mechanism by which the designer can combine a wide variety of fire safety elements into a health care facility plan that provides the level of fire safety required to balance

the calculated risk levels.

2. SCOPE

This evaluation system applies to institutional buildings used for

health care purposes involving sleeping facilities for the occupants.

In its present form, it was not designed for outpatient clinics or other

facilities where all of the occupants are normally awake. The system as presented in this report was also not designed to evaluate penal institutions and has not been proof tested against that type of occupancy.

The system to be described covers all of the aspects of building

fire safety currently covered by the Life Safety Code. A few of the

items related to built-in utility systems and to operational features

and furnishings (fire evacuation plans, fire drills, draperies, etc.)

have been excluded from the grading systems. However, these are covered

as mandated items in an attachment to the evaluation form. To be con- sidered as having demonstrated equivalent fire safety, it is necessary

that the facility satisfy these requirements in addtion to the basic

fire safety evaluation.

3. PURPOSE

The purpose of the evaluation system is to provide a technically

based mechanism applicable to health care facilities for:

a. Evaluation of an existing he care facility to determine

how the actual level of fire safety in that facility compares

to the level of fire safety that would be provided by explicit

conformance to the requirements of the 1973 Life Safety Code.

b. Evaluation of various alternative approaches available to

upgrade an existing facility to a level of fire safety that

meets or exceeds the level prescribed by the Life Safety Code.

3
c. Evaluation of a proposed new facility design to determine how

its level of fire safety would compare to that required for

such a facility by the Life Safety Code, In this aspect the

system can also be used as a design instrument to determine

various alternatives that can be considered.

d. Evaluation of the cost effectiveness of alternate fire safety

designs and methodologies.

e. Quantitative evaluation of the relative degree of protection

involved in a facility or a design feature, as compared with

that required by the Life Safety Code.

4. EQUIVALENCY CONCEPT

The evaluation system provides a method for determining the design

features needed to provide equivalence to the 1973 Life Safety Code.

Equivalency for the purpose of the system is judged by comparing the

total fire safety level prescribed by the Life Safety Code for health

care facilities to the actual safety level in a particular design or an actual facility.

The Life Safety Code represents a consensus view by knowledgeable

professionals of the minimum standard for fire safety necessary to

safeguard the public interest.

Equivalency determination is based on the concept that, while the

Life Safety Code does not include a specific statement of the level of

safety provided, it is possible by examination of the Code requirements

to establish a base line for comparing the level of safety provided by

strict conformance to its requirements with the level of safety provided

by alternative systems of safeguards. This comparison can be made on

the basis of the total safety performance of the building, including all

of its safeguards, without making direct comparisons between a specific

Code requirement for an element and the corresponding element as it

exists in the building. The concept is suitable for use with any of the

recent editions of the NFPA Life Safety Codes for 1967, 1970, 1973 and

1976. The following reference sections are quoted from NFPA 101-1973:

"1-3118. Nothing in this Code is intended to prevent the use

of new methods or new devices, providing sufficient technical

data is submitted to the authority having jurisdiction to

demonstrate that the r method or device is equivalent in

quality, strength, fire resistance, effectiveness, durability,

and safety to that prescribed by this Code."

"l-4113(c). The specific requirements of this Code for

existing buildings may be modified by the authority having

jurisdiction to allow alternative arrangements that will

secure as nearly equivalent safety to life from fire as practical, but in no case shall the modification be less

4
restrictive or afford less safety to life than compliance with

the corresponding provisions contained in this Code for

existing buildings. (See also 1-3118)."

Similar paragraphs also exist in the 1967, 1970, and 1976 editions

of the Life Safety Code.

Evaluation of equivalency of fire safety is through consideration

of three separate concepts. The first is occupancy risk, judged primarily

on: how many people are susceptible to a single fire exposure (level of

risk), what is their capability to safeguard themselves, and what is the

nature of the exposure to which they are being subjected. The second is

the capacity of the building and its fire protection systems to provide

a safe environment commensurate with the risk. The third is the degree

of redundant capabilities to insure the preservation of safety in case

of the failure of any one safeguard or method.

5. PROJECT METHODOLOGY

Development of the fire safety evaluation system consisted of three

operations: system design, professional judgment review and critique,

and system testing.

a. System Design. This consisted of: (1) analysis of the stated

requirements of the 1973 Life Safety Code versus the fire

safety function(s) of each requirement, (2) organization of

the results of this analysis into a format suitable for obtaining professional judgments of the comparative worth of the

fundamental code requirements relative to the Life Safety Code

objectives for health care facilities, (3) development of a computer program to evaluate alternative designs and fire

protection systems, and (4) iterative incorporation of system

changes resulting from the professional judgment review and

system tests.

b. Professional Judgment Review. The professional judgment

review was made by two different groups: (1) an NBS group,

through the mechanism of a "Delphi" exercise (see appendix A

for description of the NBS Delphi operation), and (2) an outside review group (see appendix B) . The Delphi group (an

ud hoc group of qualified fire protection engineers from the

Center for Fire Research, NT 0 '' refined the format, established

initial values ^f the safety y ameters, and provided judgment

values for selecting individual safety parameters in the

redundancy evaluations. The outside consulting group consisted

of prominent persons in the field of regulation and specification of fire safety requirements in health care facilities.

The group provided broad-based technical and judgmental information for improving both the format and the final values

assigned to the safety parameters and the redundancy factors.

5
c. System Testing, The testing involved a series of exercises to

determine the validity of the fire safety evaluation system.

These exercises included: field tests of actual facilities by

NBS personnel; examinations of many evaluation work sheets

completed by health care facilities owners and engineering

staff, and by code certification and inspection authorities;

and, computer analysis of alternative design systems.

6. SYSTEMS DESCRIPTION

6.1 Capabilities and Limitations

The system that has evolved from this effort provides a means of

mixing recognized and proven fire safety systems and approaches and

evaluating these mixes in terms of the overall fire safety performance

of a facility. It permits comparative evaluations of the fire risks and

fire safety factors actually present in individual facilities or design.

Those features that are in excess of minimum safety requirements are given appropriate credit, reflecting the degree of additional safety

actually provided. The credit however is limited in its application to

the methodological areas where the safeguards provide credible improvements in safety. Conversely, features that increase one or more aspects

of fire risk are appropriately charged for their detrimental impact on

safety. The result is intended to be an assessment of total safety

performance as compared to a minimum code safety level, which provides

opportunity for cost reduction, wider choice of design alternatives, and

operational flexibility at greater levels than currently available

through explicit compliance with the Life Safety Code.

The most important limitations of the evaluation system are:

a. As presently developed the evaluation system applies only to

health care facilities of the types covered under Chapter 10

of the 1973 Life Safety Code.

b. The results are expressed in equivalency to the level of

safety achieved by the Life Safety Code, and should not be

construed as a measure of total or absolute fire safety.

c. The system, like all existing methods for regulating or evaluating fire safety, is only partially supported by technical information or statistics. The professional judgment of

experts in a series ^ r alanced peer-consensus groups is used

to bridge the technology gaps.

d. In general the evaluation system is limited to evaluating the

interrelationships of those fire safety methodologies and

approaches that are defined in the Life Safety Code. There is no basis in the system for accommodating completely innovative

approaches (such as automatic venting at the point of fire or

6
the use of halogenated gases as a general protection system)

for which equivalency with the Life Safety Code cannot be

determined.

e. While the parameter measurements of the system cover built-in

structural materials and elements, space arrangement, and fire

protection systems and devices, the system does not permit

alternate approaches to meeting the Life Safety Code requirements for:

(1) Utilities such as heating, air conditioning, electrical,

and incinerator systems.

(2) Furnishings such as draperies, curtains, wastebaskets,

and beds.

(3) Administrative activities such as emergency plans and

fire drills.

When using the evaluation system, the existing requirements in

these three areas are applied in the traditional manner of

explicit conformance with the established standards and requirements as described and/or referenced in the Life Safety Code.

A form to accomplish this in terms of ten specific requirements

is shown in figure 23 e.

6.2 Logic

The logic of the system is that the level of risk imposed upon

persons in a facility must be met by a system of safeguards that provide

sufficient safety to protect against that risk, using several interacting

but separate design approaches.

The evaluation is made on a

" FIRE/SMOKE ZONE " basis. This is in

recognition of both the history of fires in health care facilities and

the traditional arrangements of patient care areas. The evaluation of

fire safety is relevant both to the capability of patients surviving

fire initiated in such a unit, and to the ability of the unit to exclude

the impact of fires external to it. The term "fire/smoke zone" is

defined as a space separated from all other spaces by floors, and by

horizontal exits or smoke barriers. Where a floor is not subdivided by

horizontal exits or smoke barriers, the entire floor is the zone.

The evaluation syste" applies tl gic to each patient use fire/

smoke zone through the following steps.

a. Measure RISK .

b. Measure overall (GENERAL) level of safety.

7
c. Measure depth (redundancy) of safeguards in terms of:

(1) Fire CONTAINMENT capabilities.

(2) EXTINGUISHMENT , suppression, and control capabilities.

(3) PEOPLE MOVEMENT and other occupant protective features.

d. Determine equivalency to the prescribed requirements of the

Life Safety Code. Equivalency occurs when the values as measured by this system are such that:

(1) The GENERAL safety level equals or exceeds the occupancy

RISK level, and

(2) The CONTAINMENT , EXTINGUISHMENT and PEOPLE MOVEMENT

safety levels each independently equals or exceeds the

minimum value corresponding to the level of that category

required by the Life Safety Code.

6 . 3 Risk

In establishing a system for evaluating risk, it is recognized that

there is a basic level of fire risk inherent in every health care facility. It is also recognized that the amount of furniture, equipment, and

supplies (plus the arrangement of these within the space available)

depends on the occupant and is not quantified in the safety equivalency

measurement. The evaluation system base line for occupancy risk rests

on the assumption that the furniture*, equipment, and supplies will be

combustible, most adversely located from a fire-safety standpoint, and

typical of those normally found in health care facilities.

The factors used to judge the variations in fire risk are given in

figure 1. They are applied to individual fire/smoke zones and cover the

following risk controlling parameters: the number of patients in the

zone, their degree of mobility, their average age, the ratio of patients

to attendants, and the height of the zone above street level. These

five specific occupancy risk parameters were initially chosen based on

the experience and judgment of selected members of the staff of the Fire

Safety Engineering Division, Center for Fire Research , and because they are considered to represent the occupancy variables that control the

risk in health care facilities. The assessment of the specific parameters

and the determination of their relative importance was also based on judgment plus the exercising of J ' ' system on test cases to reveal

inconsistencies or deviations from accepted safety practice.

The Occupancy Risk Factor for any health care building is the

product of five individual risk parameters factors based on the risk

factor values shown in figure 1.

^Facility furniture could be expected to vary ad hoc so they cannot be

considered as known in a system analysis.
The minimum risk conditions have been defined as: a zone containing

fewer than five patients, all of whom are of sufficient health to be

considered fully mobile and capable of evacuating themselves, their

average age being less than 65 and over one; a ratio of patients to

attendants of 2:1 or less; and the zone located on the first floor of

the building. This condition is assigned an occupancy risk factor of

1 . 1 .

In contrast, the conditions evaluated as representing the upper

range of risk as contemplated by the Life Safety Code are based on: more than 30 patients in the zone, all of whom are unable to move without

assistance; their average age is over 65 or under one; a ratio of patients

to attendants of 10:1 or more; and the zone located above the sixth

floor or in the basement. This was assigned an occupancy risk factor of

18. Greater risk values are assigned to patients who cannot be moved

and to fire zones which are unstaffed. The maximum possible risk has a factor of 69.

The risk factors were chosen and weighed in descending order of

maximum impact as follows:

a. Patient Mobility. The single most important factor controlling

risk in a health care facility is the degree to which patients

must be assisted in taking actions necessary for their safety.

The level of capability in health care facilities will vary

from patients who, if informed or directed, will be able to

take positive self-protecting actions to those patients who

cannot be moved or cannot take the simplest actions to safeguard themselves. In the measurement of occupancy risk factors

the least mobile category of patient expected in the zone determines the risk factor for that zone. The rationale for

this approach is that if a zone accepts any patient with a reduced mobility status, at any time it may increase the

number of those patients. For patients who cannot be moved

because of extreme danger of death or serious harm, this

condition is considered to be a major risk and a very high

risk factor (4.5) is imposed. With this high risk factor, the

system requires inclusion of fire safeguards which exceed the

normal minimum requirements of the Life Safety Code sufficient

to compensate for total lack of movability. This is one of

two situations where it is possible for a building, which

explicitly complies with the Life Safety Code, to fail to meet

the minimum requirements as determined by the evaluation

system.

b. Patient Density. The risk factor for occupant density (number

of patients within the zone) takes into account both the

inherent increase in the maximum fire death potential that occurs as the number of patients in a zone increases, and the

problems involved in handling larger numbers of patients

during an emergency.

9
c. Fire/Smoke Zone Location. This risk factor relates to fire

department accessibility to the fire. The rating system

recognizes the inherent advantage of a first floor zone. It

also recognizes the problems of evacuation from higher floors

and the virtual impossibility of using external fire fighting

efforts above the sixth floor in any building. The risk

factor value for zones in basements is the same as for zones

at or above the seventh floor.

d. Ratio of Patients to Attendants. This risk factor recognizes

the importance to patient safety of attendants immediately

available to respond in an emergency. The emergency actions

that may be undertaken by the staff include detection, alarm,

fire extinguishment, confinement of the fire, establishing

barriers between the patients and the fire (e.g. closing

patient room doors), rescue, emergency medical aid, and other

related functions. A few of these functions, such as detection

and alarm, may not be critically related to the ratio of

attendants to patients while those functions related to rescue

and the closing of patient room doors have a strong relationship

to the staffing ratio. The staffing ratio considered is based

on the minimum staffing level that would be immediately available

(normally night hours). In establishing the risk charges, the

charge considered equivalent to the most severe case contemplated under the Life Safety Code was assumed at a patient/

attendant ratio of 11 or more, but where there was at least

one attendant constantly in or immediately adjacent to and in

full observation of the zone. The Life Safety Code is actually

silent on this matter and could even be interpreted to permit

a situation where there were no attendants in or adjacent to

the zone. Such a condition was considered to be a major fire

risk and a high risk factor (4.0) is imposed in a situation

where patients are left without immediate nursing staff assistance. With this high risk factor, the system requires inclusion

of sufficient fire safeguards to reasonably compensate for the

lack of human supervision. This is a second situation in

which it is possible for a building with fire protection

devices to explicitly comply with the Life Safety Code, but to

fail to meet the minimum requirements as determined by the

evaluation system.

e. Patient Average Age. This risk factor recognizes the increased

susceptibility of the elderly and infants up to one year of

age to physical harm 1 '.moke particles, gaseous combustion

products and heated air. The rating assigns a larger risk

factor (1.2) to fire zones occupied by a population whose mode

is above 65 or below one year. Basically, imposition of this

charge will provide additional safety protection in nursing

homes for the aged and nurseries.

10
6.4 Safety Parameters

The general safety factors are measures of those building and fire

protection features that bear upon the safety of patients (and other

occupants) who may be in the particular fire/smoke zone at the time of a

f ire.

The safety parameters were selected by examining the specific code

element requirements for health care facilities, Chapters 10 and 17 of

the 1973 Life Safety Code, and by evaluating the impact of various

elements of the Code. The selected safety parameters were modified

first by the NBS Delphi panel and later by the consultant groups. The

selected safety parameters are shown in figure 2. (See appendix C for an accounting of the inclusion of code elements in the evaluation system.

)

Each of the safety parameters was analyzed. Where the current Code

requirements recognize several different levels of a parameter (e.g. the

Life Safety Code recognizes eight different types of construction),

the most important alternatives were listed. In addition, conditions

likely to be encountered in situations failing to meet the explicit Code

requirements, and conditions exceeding those required by the Code but

available for increased protection were also listed. Figure 3 shows the

final "matrix" form of the breakdown of the 13 selected safety parameters,

each having three to seven subdivisions.

The safety parameters are designed to constitute a complete assembly

of all of the basic building factors determining the level of safety in

a health care facility for which equivalency could be expressed. In

addition, we collected and attached to the inspection form an additional

series of items required by the Life Safety Code but outside the scope

of the equivalency covered by the listed safety parameters. These relate

primarily to building utilities, operational features and furnishings

and they are listed in part e of figure 23.

6.5 Safety Parameter Valuation

In order to provide a method of bringing the best available con- sensus judgment and experience together to judge the relative impact on general safety of each of the parameters in each of the potential

conditions listed, a Delphi type peer group was established. This peer

group consisted of members of the Fire Safety Engineering Division,

Center for Fire Research, NBS, with the greatest background and experience

in the application of fire protection engineering principles and practices

to buildings. The membership and basis for the Delphi approach are covered in appendix A.

Each member of the group was provided with copies of the initial

matrix similar to the one shown in figure 3, but without numerical

parameter values. Each person then evaluated the relative importance of

each item in the entire matrix of parameters without consultation with

other members of the group. The members of the Delphi group were advised

that the risk being considered covered new and existing health care

11
facilities and that the objective was a system to measure equivalency

with the 1973 Life Safety Code. The value judgments made by this group

are, therefore, considered to be based on the character and needs of

patients in health care facilities and the current approach to these

embodied in the Life Safety Code. In addition, each member of the group

evaluated separately the same matrix in relation to the redundant subsystems which are discussed in section 7.7. In executing the matrix

each peer group member was requested to assign a value of +10 to that

safety parameter element (or level) considered to be the single most

important to safety to life and to compare all other elements in the

matrix to that base. A zero value represented a neutral condition; i.e.

a safety parameter at this level would not increase or decrease the

safety conditions of a fire zone. Negative values represented deficiencies; i.e. safety parameters at this level decreased the safety

conditions of a fire/smoke zone.

After an initial analysis of the results, the peer group was asked

to meet in conference on several occasions. The peer group on those

occasions deviated from the traditional Delphi approach but instead

reviewed differences and concepts, with a view to achieving consensus

agreement on categories and on selection of the numerical values.

Several categories were modified and qualified. A significant

adjustment was to shift the numbers so that a base line would be established in which negative charges would not be made against any general

safety parameter that was in explicit conformity with the requirements

of the 1973 Life Safety Code.

6.6 Relating Safety Parameter Values to Life Safety Code Requirements

The relationship between the safety parameter values and the code

requirements was established by summing the value of all of the credits

and deficits of the safety parameter elements for a health care facility

that exactly met all of the requirements prescribed by the 1973 Life

Safety Code. Attempts to do this disclosed that the Life Safety Code

actually had eleven sets of requirements, seven for sprinklered facilities

and four for non-sprinklered facilities (see figures 4 through 18).

Based on the relative value of protection methodologies developed by the

Delphi group and refined by the review processes described later in this

report, the levels of safety prescribed by these requirements are:

12
General Safety Value Required

Non-Spr inkiered Sprinklered

Buildings Buildings

1 . New buildings 1-story in height 13 16

2. New buildings over 1-story

in height. 18 23(a)

3. Existing buildings 1-story

in height. 5 8

4. Existing buildings over 1-story in height. 9 16(b)

(a) 20 for 2- or 3-story buildings.

(b) 14 for 3-story and 10 for 2-story buildings.

These values represent the level of general safety required by the

1973 Life Safety Code to house health care occupants in the class and

height of building indicated. The analysis demonstrates that, in terms

of the values in the evaluation system, the Life Safety Code minimum

requirements are those for non-sprinklered buildings. The highest total

value developed for a non-sprinklered building is 18. The importance of

this value is that it was used as the approximate base line for the

establishment of measurement of risk in a multi-story building and is

the principal balance point for comparing occupancy risk with general

safety. Thirteen is the comparable value for a single story building.

The values for existing buildings demonstrate the reduced level of

general safety accepted by the Life Safety Code for these buildings.

For a one-story building the general safety value is +13 for a new building and +5 for an existing building, indicating that for an existing

one-story building only 38% of the score expected a new one-story building

is required. Similarly, the ratio of existing multi-story buildings to

that for new multi-story buildings is 1/2. The 0.5 factor in table 3B

of the Fire/Smoke Zone Evaluation Work Sheet reflects this ratio.

6.7 Redundant Safety Subsystems

A basic principal of the Life Safety Code is that there will be a redundancy of protection so that the failure of a single protection

device or method will not result in a major failure of the entire safety

system. In addition, the development of a redundant approach, as used

in this safety evaluation system, avoids the pitfall of traditional

approaches to developing grading systems where all of the elements are considered mutually exclusive of each other and a single total score determines acceptability. Under such a system, it is possible to com- pletely disguise the absence of a critical element. The evaluation

system establishes redundancy on the basis of in-depth coverage of the

principal fire safety methodologies. The redundant methodologies used

in the system are those related to fire safety through containment,

through extinguishment and through people movement (including refuge)

.

13
The redundant methodologies were chosen after examination of decision

tree approaches [1,2].-*- These divide fire protection by element. Four

different methodologies of managing fire impact were identified. These

are control of the fuel and arrangement; compartmentation and other

mechanisms of containment of the fire and its impact; extinguishment

suppression and other means of terminating fire development; and the

provision of safe locations of refuge either by evacuation or by establishment of safe areas of refuge. Those elements related to the control of

fuel and its arrangement are incorporated into the risk analysis portion,

in terms of the occupancy risk base line. Therefore, only three redundant

methodologies were used in the analysis.

As part of the initial Delphi exercise, each member of the Delphi

group completed a matrix establishing his judgment on the relative

importance of the items in the general safety parameter matrix; he also

made additional judgments on the same matrix elements related to the

separate fire safety methodologies of containment, extinguishment, and

people movement. These were then processed and analyzed and reviewed in

subsequent conference meetings of the Delphi group. By this process,

the parameters that have a significant impact on each of the redundant

methodologies were identified. Many of the parameters impact on more

than one of the methodologies. In the judgment of the group only sprinkler

protection impacts on all three. Figure 19 shows the breakdown in terms

of which parameters apply to which methodologies.

Each of these subsystems was then evaluated to determine the point

value that would result from explicit compliance with the requirements

of the Life Safety Code for that subsystem. Because of the variance

between new and existing buildings and between single story and multistory-type buildings, four values were determined for each of the

redundant safety methodologies. Figures 20, 21, and 22 demonstrate how

these values were established.

In this fire safety evaluation system these values are mandatory

minimum values that must be met regardless of the overall evaluated

level of occupancy risk or the overall evaluated level of general safety.

6.8 Overall Safety Evaluation of a Fire/Smoke Zone

This evaluation system determines the efficacy of any arrangement

of the listed fire safety subsystem elements in a fire/smoke zone by

considering the risk factors and safety parameters relative to the level

of safety that would be achieved by explicit conformance with the specific

requirement of the Life Safety Code ( (NFPA 101-1973). In order to be

determined as equivalent the measurement must demonstrate that:

1. The general safety level produces a value that equals or exceeds

the determined value or charge for risk.

iNumbers in brackets refer to the references at the end of this paper.

14
2. Each of the three individual redundancy groupings (containment

safety; extinguishment safety; and people movement safety) must

have an arrangement of safeguards that meet the prescribed minimum

for that redundant grouping independent of the other condition. 7.

FIRE/SMOKE ZONE EVALUATION WORK SHEET

FOR HEALTH CARE FACILITIES

All of the parameters, variables and formulas for determining the

facility safety equivalency with the Life Safety Code are contained in a self-instructing form. A separate manual (appendix D) has been prepared

to assist in completion of the evaluation form. The manual provides

expanded discussions and definitions of various items in the evaluation

sheet to assist the surveyor or reviewer when questions of definitions,

interpretations, or meanings arise. To evaluate totally a health care

facility, it is necessary to evaluate each of the different fire/smoke

zones. A zone is any space which is separated from all other spaces by

floors, horizontal exits, or smoke barriers. Where a floor is not

subdivided by smoke barriers, the entire floor is the zone. See figure

23 for an example of the form and appendix E for examples of a completed

form.

8.

COMPUTER ANALYSIS

The evaluation system has a theoretical capability of evaluating

about 230 million combinations of the 13 safety parameters and variations.

Practical arrangements in existing buildings and future design are of

the order of a few thousand. For the purpose of verifying the original

proposed system as well as to analyze potential proposed changes, a computer program was developed. The program generates all arrangements

that are valid, based on data given for the safety parameters. Using

the Fire Safety Evaluation Work Sheet an experienced engineer or facility

can manually analyze 10 to 15 differently organized zones, and establish

the most suitable configuration for the facility. By using the computer

program the evaluator is able to review all possible solutions to his

problem, and he can also be assured that answers are not biased by

individual preference. The printouts of the zone arrangements can be

easily analyzed by an experienced individual to establish equivalency of

solutions. Appendix F provides additional detail on this program.

9.

EVALUATION SYSTEM ANALYSIS

An effort has been made to make the system consistent with accepted

and sound fire protection engineering practice and theory. While the

most advanced scientific knowledge has been used in developing the

system, the state-of-the-art requires that the insight and professional

judgment of experts in the field serve as the base for information in

developing the system, and the available technical knowledge (including

results of fire tests, statistical analyses, fire investigations, etc.)

15
serves a supportive role. In the development of the fire safety evalua

tion system, therefore, both the NBS Delphi group and the professional

consulting panel described in sections 9.1 and 9.2 below were selected

on the basis of expertise and interest.

In the systems proofing effort the capacity of these panels was broadened by using a two-step judgment approach. In the first step the

relative worth of each parameter was individually judged on its relationship to other parameters. This evaluation was made in terms of each

parameter’s contribution to both general safety and to each of the

redundant safety requirements. In the second phase the parameter values,

developed in the preceding phase, were applied to a large number of test

cases, scenarios and reviews of specific facilities. The resulting fire

safety system configurations were then judged on overall equivalency to

configurations prescribed by the 1973 Life Safety Code. This process

provided a balance and cross check between judgments of the value of the

individual parameters and evaluations of the overall product.

9.1 NBS Delphi Group

The initial safety parameter values (figure 3) were established by

the NBS Delphi group. The group was composed of qualified fire protection

engineers in the Fire Safety Engineering Division (see figure 24). The

group was also used at different development stages to clarify technical

problems and to analyze proposed changes suggested by the outside con- sultants, HEW or others.

Delphi is a procedure for obtaining the most reliable consensus of

opinion of a group recognized as experts on a technical question for

which no "true" answer is within the state of current knowledge [3].

The essence of the process is that the question is considered independently by members of the group. The response is tabulated and circulated

to group members who revise their "answers" on the basis of further

thought and consideration of the aggregate response. Additional rounds

of response involving direct contact and discussion among the group

members can ensue. The number of interactions is usually limited to

four. In its classic form Delphi incorporates various statistical

measures of the "convergence" to consensus, which are circulated within

the group along with the responses. The Delphi exercise at NBS was in a form known as Policy Delphi. In this variant the statistical measures

to establish convergence consensus are foregone and the "referee" or manager of the process takes a fairly active role in the discussion

among the group members. In any of its formats, Delphi is widely perceived as furnishing useful information in areas in which questions are difficult to pose precisely, let alone answer definitely. A more detailed

discussion of the Delphi operation is given in appendix A.

9.2 Consultant Group

After the NBS Delphi group agreed on an initial set of parameters

and their values, the system was presented to the consultant group.

16
The group consisted of prominent persons in the regulation or specification of fire safety for health care facilities. It included

regulatory officials, code writing officials, government agency fire

protection chiefs, and accrediting officials representing a cross section of the applied field. The membership and dates of meetings are shown in appendix B. This consultant group contributed to the development of the system and met in four separate sessions. In those meetings

the consultants operated as a committee of the whole, reviewing the

concept and individually discussing and evaluating the parameter values

as developed by the NBS peer group. Important revisions resulted. Many

of these revisions were in the form of restraints placed on the degree

of liberality in the safety parameter values so as to require a more

conservative and supportable approach.

9.3 Inter-Group Relationships

Throughout the project the project staff maintained liaison and a flow through the described review groups and a recently established task

group of the National Fire Protection Association Committee on Safety to

Life. This task group is studying the evaluation system for possible

inclusion in the NFPA Life Safety Code. Figure 24 outlines this flow.

10. SUMMARY

The conclusions resulting from this study are briefly stated as follows

:

a. A methodology has been developed and described for generating

equivalency to a specified set of occupancy safety requirements.

It is based on the understanding of level of occupancy risk,

building safety and redundancy of safeguards. This methodology can provide the necessary flexibility for a designer to achieve minimum

cost solutions for a specified level of safety.

b. The described methodology "System for Fire Safety Evaluation of

Health Care Facilities," is a specific example of an equivalency

approach. The system provides equivalency to the minimum life

requirements for the health care facility as prescribed by Life

Safety Code 101-1973. The system can be updated for later Life

Safety Code editions for health care facilities.

c. Other equivalency systems can be developed for other occupancies

but this will require detailed analysis of the risk level, the

variety of building safety requirements, the necessary redundance

equations, and other aspects of the specific occupancy involved.

CONCLUSIONS:

1. [ ] All of the checks in Table 7 are in the “Yes” column. The level of fire safety is at least equivalent to that prescribed by

the Life Safety Code*

2. [ ] One or more of the checks in Table 7 are in the “N r>” column. The level of fire safety is not shown by this system to be

equivalent to that prescribed by the Life Saiety Code.* The equivalency covered by this worksheet includes the majority of considerations covered by the Life Safety Code. There

are a few considerations that are not evaluated by this method. These must be separately considered. These additional considerations are covered in the “Facility Fire Safety Requirements Worksheet.” One copy of this separate worksheet is to be completed for each facility.

APPENDIX A

NBS DELPHI GROUP

Delphi Method

The Delphi technique was developed in the 1950's for the purpose of

estimating the probable effects of atomic bombing attacks on the United

States. Since then it has been applied to technological forecasting as well as in areas where judgmental information is required. The Delphi

technique is basically concerned with the utilization of the combined

knowledge of experts to arrive at a consensus opinion where factual

information is incomplete.

The NBS exercise followed a process called Policy Delphi. The

basic premise of the Policy Delphi is that it acts as a precursor to a committee activity. The Policy Delphi is not a substitute for research

studies, analyses, or staff work. It is, however, an organized method

for correlating views and information pertaining to a specific problem

area and for allowing the respondents representing such views and information the opportunity to react to and assess differing viewpoints.

Because the respondents are anonymous, fear of potential repercussions

or embarrassment is removed and no simple individual need commit himself

publicly to a particular view until after the alternatives have been put

on the table.

Turoff in "The Policy Delphi"* analyzed committee and Delphi process

The study points out that a Delphi followed by a committee provides good

results in formulating policies.

The study identifies two major areas of problems with large size

committees (i.e., communication and psychological). The communication

difficulties are attributed to the diverse membership. The major lack

of understanding tends to be between the following groups: individuals

who are not familiar with many of the new decision aids coming out of

operation research and system analyses but who have an intuitive feel

for the complexities of the organization, and individuals who have been

trained in many of modern management techniques and who are sometimes a little too confident that these approaches can be applied to every

problem. The problems associated with operation of committees that trend

to reflect psychological characteristics are:

- The domineering personality, or outspoken individual that takes over committee process.

- The unwillingness of individuals to take a position on an issue

before all facts are in or before it is known which way the majority

is headed.

- The difficulty of publicly contradicting individuals in higher

positions

.

*Murray Turuff, "T he Design of a Policy Delphi," Technological Forcasting

and Social Changes 2, No. 2 (1970).

A-l
- The unwillingness to abandon a position once it is publicly taken.

- The fear of bringing up uncertain ideas that may turn out to be

idiotic and results in loss of face.

The above limitation may also apply to small size committees, except

when the members of the small committee are given sufficient time to

consider and explore the issue, and have assurance that the privacy of

their respective remarks will be respected outside the committees.

Under those conditions a small committee will not have any of the

difficulties which have been identified for the large size committee.

Usually Delphi, whether it is to be conventional or computerized,

undergoes four distinct phases. The first phase is characterized by

exploration of the subject under discussion, wherein each individual

contributes additional information he feels is pertinent to the issue.

The second phase involves the process of reaching an understanding of

how the group views the issue. If there is significant disagreement

among members, the disagreement is explored in the third phase to bring

out the underlying reasons for differences and possibly to evaluate

them. The last phase, a final evaluation, occurs when all previously

gathered information has been initially analyzed and the evaluations

have been fed back for consideration.

There are two methods of gaining consensus: conventional and

computerized. In the conventional form, a monitor team designs a questionnaire which is sent to a respondent group. After the questionnaire is returned, the monitor team summarizes the results, and based

upon the results develops a revised questionnaire for the respondent

group to answer. The respondent group is usually given at least one opportunity to revise its original answers after examining the group

response

.

The computerized method replaces the monitor group to a large

degree with a computer which has been programmed to carry out the com- pilation of the respondent group results. This process has the advantage

of eliminating delays in summarizing each round of Delphi, thereby

turning the process into a real-time communication system. However, it

does require that the information received from the respondents is in a form that can be fed into a computer and that an algorithm can be provided

to analyze the data. The NBS Delphi Group used the conventional fourphase approach in its evaluation process.

Approach Used in Developing Fire Safety Parameters and Their Values

CFR Delphi Group

Seven individuals from the Engineering Division of the Center for

Fire Research were chosen to act as a "Delphi" group. The experience of

the group members in areas of fire/life safety ranged from six to

thirty-five years. (Table A-l identifies the group members.) Each

individual was briefed about the general nature of the life safety risk

A2
analysis system and was given a detailed description of the safety

model. The individuals were encouraged to seek more information about

the system or any individual parameter, if the information given to them was insufficient. No guidance was provided as to the importance of any

sub-model or individual parameter.

Instructions for Completing of Forms

Each member of the group was given four separate but identical

forms, one for each of four fire safety functions: 1) containment

safety; 2) extinguishment safety; 3) people movement safety; A) general

safety, (see figure A-l) . He was told that the safety requirements

should be considered only as they apply to health care facilities. He was also instructed that the safety impact of each requirement should be

established on a fire/smoke zone basis. Specific instructions for

filling out the questionnaire were:

1. Evaluate the relative worth of the safety requirement, (i.e.

parameter) on each of the four fire safety functions, one function at a time, and record conclusions on the appropriate questionnaires.

2. Use numerical values to express the level of safety for each

subdivision of each parameter.

3. The numerical values should range from (+10) for the highest

level of safety to (-10) for the condition creating the most severely

hazardous condition. Where the parameter status neither provides safety

nor creates a hazardous condition, a "zero" value should be assigned.

4. Add additional safety parameters to any of the questionnaires,

if required to provide a more complete safety evaluation.

5. Increase the number of parameter subdivisions, if the number

shown on the forms is insufficient.

6. Remarks may be made on each of the four forms.

Analysis of the Questionnaires

1. Forms . The completed forms were checked for completeness,

illegible numbers and remarks. Where required, individuals were asked

to provide additional information to complete the questionnaire. Figure

A-2 shows the format agreed to by the Delphi group.

2. Preparation of Parameter Values . Some individuals did not use

the entire range of suggested numbers (+10 to -10) . Therefore, the set

of numbers from their forms was normalized tc be compatible with the

other forms. Each individual was requested to submit 216 values, which

made the process of adjustments quite laborious. The values for each

safety level were clustered to identify where major deviations occurred.

An individual who supplied values significantly different from the

cluster was asked for the reasoning behind his choice. Mostly the

A3
differences were generated by misinterpretations of the safety parameter

functions. The values were then adjusted by the individuals and the

process of preparing a consensus safety parameter table began.

3. Safety Parameter Table . After adjustment of the parameter

values as described above a single table of safety parameters was prepared

using the arithmetic means (see figure A-3) . All the values were expressed

as whole numbers rounded off toward the "conservative" side.

4. Safety Parameter Selection for the Three Sub-models . It was recognized that all of the selected parameters were not important in

providing safety in a particular fire safety function. Based on the

response of the group, a process was developed to assign only those

parameters which provide significant values in evaluating a prescribed

life safety function. The three functions are: containment, extinguishment, and people movement safety. (There is- also the general safety

function) . For each of the three functions a set of three tables was

prepared. The first table had all the values of each parameter as assigned by the individual respondent. The second table was similar to

the first except numerical values were clustered in six ranks as follows:

High (10-8); Medium (7-4); Low (3-0); Negative Low (-1 to -3); Negative

Medium (-4 to -7); Negative High (-8 to -10). The third table ranked

the parameters, according to whether they provided maximum or minimum

safety. Based on the information from the third table, safety parameters

were chosen for each of the sub-models. Seven parameters were assigned

to the containment safety sub-model; five parameters were assigned to

the extinguishment safety; and seven parameters were assigned to the

people movement safety. (See figure A-4)

.

5. Results . The analysis of the questionnaire filled out by the

Delphi respondents provided the basis for assigning numbers to each

subdivision of each parameter as described above, assigning parameters

to the safety function; and dropping or changing parameters. The group

did not assign sufficient positive or negative values to two proposed

safety parameters (ratio of patients to attendants in the zone, and

emergency brigades in health care facility). Therefore, the parameter

on the brigades was dropped from future group evaluation; and, the

parameter on the ratio of patients to attendants in the zone was transferred to the risk model (see figure 23-A) . The group suggested that

the construction safety parameter be broken into more categories, to be

more meaningful as well as to "'a_lect better conformance with the Life

Safety Code. The results were summarized in new tables which were

presented to group meetings. The group discussed the proposed forms and

suggested additional changes. The construction safety parameter was reorganized and presented to individual members for evaluation as well

as for the assignment of values for each level of safety. The values

were analyzed and a single set of values was generated and included in

the safety parameters table.

6. Adjustments . The Delphi group was instructed to make evaluations on the merit of the safeguards being judged without reference to

! A-4
specific requirements of the Life Safety Code. The initial safety

parameter table contained negative values for several parameter levels

that met requirements of the Life Safety Code (fire resistive partitions, smoke detection, corridor flame spread). The group made a decision that these parameter levels should have at least a "zero"

safety value. These negative parameter values (for the specific code

requirements) were then adjusted to the "zero" value. Each parameter

which had a level upgraded was then adjusted so that all of the levels

of that parameter reflected the necessary changes.

7. Delphi Group Status . The Delphi group finished its prime

assignment to provide the basic system to be analyzed by the outside

consultant group. The Delphi group also met several times after finishing this initial assignment, to consider adjustments or changes to the

system suggested by the outside consultants or identified through NBS

research. At each meeting the group analyzed the problem and suggested

possible improvements to the system.

N.A.

10-0001. Institutional buildings are those used for purposes such

as medical or other treatment or care of persons suffering from

physical or mehtanilness, disease or~tn'firmfty ; for the care of in- fants, convalescents or aged persons; and for penal or corrective purposes. Institutional buildings provide sleeping facilities for the occupants and are occupied by persons who are mostly incapable

of self-preservation because of age, physical or mental disability, or because of security measures not under the occupants’ control. Buildings or sections of buildings which house, or in which care is rendered to mental patients who are capable of average judgment

in taking action for self-preservation under emergency conditions,

in the opinion of competent medical authority approved by the

state agency having jurisdiction, may come under other sections of

this Code instead of Section 10-1. Sections of institutional buildings may come under other occu- pancy classifications regarding exit requirements if these areas are not used to house institutional occupants, or are not areas in which

these persons are treated or to which they have normal access, or which serve as a means of egress for them.

Institutional buildings comprise three groups: groups (a) and (b) are treated together in Chapter 10, and group (c) is considered

separately:

(a) Health Care Facilities (Hospitals and nursing homes)

(b) Residential-Custodial Care (Nurseries, homes for the aged,

mentally retarded care institutions, etc.)

(c) Residential-Restrained Care (Penal institutions, reformatories, jails, etc.) See Section 10-3.

N.A. 10 0002. Institutional occupancies shall include all buildings or parts thereof with occupancy as described in 10-0001.

C-2
Evaluation*

Worksheet LSC-1973

N.A. 10-0003. All institutional buildings shall be so designed, constructed, maintained, and operated as to minimize the possibility of a fire emergency requiring the evacuation of occupants. Because the

safety of occupants of institutional buildings cannot be assured adequately by dependence on evacuation of the building, their protection from fire shall be provided by appropriate arrangement of

facilities, adequate staffing, and careful development of operating

and maintenance procedures composed of the following:

(a) Proper design, construction, and compartmentation;

(b) Provisions for detection, alarm, and extinguishment; and

(c) Fire prevention and the planning, training, and drilling in programs for the isolation of fire and transfer of occupants to areas of refuge or evacuation of the building.

N.A. 10-0004. It is recognized that in buildings housing various types

of psychiatric patients, or used as penal institutions, it may be neces- sary to lock doors and bar windows that are equipped to confine

and protect building inhabitants. Other sections of this Code re- quiring the keeping of exits unlocked may be waived by the authority having jurisdiction. It is also recognized that some psychiatric

patients are not capable of seeking safety without guidance. In

buildings in which doors arc locked or windows are barred, provisions shall be made for the rapid removal of occupants by such re- liable means as the remote control of locks or by keying all locks to keys carried by attendants.

N.A. 10-0005. Definitions

(a) Hospital — a building or part thereof used for the medical,

psychiatric, obstetrical or surgical care, on a 24-hour basis, of 4 or more inpatients. Hospital, wherever used in this Code, shall include

general hospitals, mental hospitals, tuberculosis hospitals, children’s

hospitals, and any such facilities providing inpatient care.

(b) Nursing Home — a building or part thereof used for the lodging,

boarding and nursing care, on a 24-hour basis, of 4 or more per- sons who, because of mental or physical incapacity, may be unable

to provide for their own needs and safety without the assistance of another person. Nursing home, wherever used in this Code, shall include nursing and convalescent homes, skilled nursing facilities, intermediate care facilities, and infirmaries of homes for the aged.

(c) Residential-Custodial Care Facility — a building, or part thereof,

used for the lodging or boarding of 4 or more persons who are in- capable of self-preservation because of age, or physical or mental

limitation. This includes facilities such as homes for the aged,

nurseries (custodial care for children under 6 years of age), and

mentally retarded care institutions. Day care facilities that do

not provide lodging or boarding for institutional occupants are not covered in this section of the Code.

.
Fire/Smoke Zone - A f ire/ smoke zone (zone) is a space which is separated

from all other spaces by floors, horizontal exits, or smoke barriers.

Where a floor is not subdivided by horizontal exits or smoke barriers

the entire floor is the zone.

NOTE: Patient sleeping rooms or suites exceeding 1,000 square feet of

floor area should be evaluated as follows:

a. If the room or suite has a single exit access door, it should

be evaluated as a single dead-end zone.

b. If the room or suite has 2 or more exit access doors, it

should be evaluated as either a room in a zone or as a separate

zone, whichever gives the better (higher) rating.

Selection of Zones to be Evaluated - For a complete evaluation, every

zone in the health care facility should be evaluated individually. From

a practical standpoint most health care facilities have repetitive

arrangements so that a complete picture can be developed by evaluating

typical zones until all combinations are evaluated. The zones selected

should include:

A. Each type of patient zone having a different type of mobility,

density, or attendant ratio as classified in Table 1 of the work

sheet

.

B. Each zone that represents a significantly different type of construction finish, or protection system.

C. Zones containing special medical treatment or support activities

(operating suites, intensive care units, laboratories).

D. Zones not involving housing, treatment, or customary access for

patients as follows:

1. Any zone, whether used for patient egress or not, may be evaluated

on the same basis as a patient use zone. In such case the value of

factor F in Table 2 shall be assigned the value of factor L (Fire

Zone Location) from Table 1. In such cases Item 10, Emergency

Movement Routes shall be graded "Deficient Capacity" if the exit

capacity is less than that prescribed for the actual occupancy of

the space and as 2 routes" if less than 75% of the prescribed

exit capacity is present.

2. If the zone is separated from all patient use zones by two hour

fire resistive construction (including any members that bear the

load of a patient zone and with Class B fire doors on any communicating openings), it may be excluded from evaluation. In such case

that space shall conform with the portion of the Life Safety Code

appropriate to its use. In addition appropriate charges under Item

8, Hazardous Areas, in Table 4 shall be charged against other zones

in the facility.
Maintenance - Any protection system, requirements, or arrangement which

is not maintained in a dependable operating condition or is used in such

a manner that the intended fire safety function or hazard constraint is

impaired should be considered as defective and receive no credit in the

evaluation.

Table 1

Occupancy Risk (General Discussion) - In establishing a system for

evaluating occupancy risk, it is recognized that: (1) there is a basic

level of risk inherent in every health care facility; (2) that the fuel

characteristics of furniture, equipment, and supplies vary with time;

and (3) that the arrangement of these items within the space available

also may vary with time.

Consequently, these three factors are not included as parameters in a safety equivalency measurement. To account for these factors, the

occupancy risk base line is set at the inherent risk level with the

presumption that the furniture, equipment And supplies will be the most

combustible and adversely located (from a fire safety standpoint) of

those normally found in health care facilities.

1. Patient Mobility

The single most important factor controlling risk in a health care facility is the degree to which patients must be assisted in taking

actions necessary for their safety. The level of capability in health

care facilities will vary from patients who, if informed or directed,

will be able to take positive self-protecting actions to those patients

who have no ability to move or even to take the simplest actions to

safeguard themselves. In some cases patients may be directly connected

to a fixed life support system and so intimately dependent upon it that

regardless of their physical condition or the availability of assistance

they cannot be moved without jeopardy of death or serious harm. In the

measurement of occupancy risk factors the least mobile category of

patient expected in the zone determines the risk factor for that zone. The rationale for this approach is that if a zone accepts any patient

with a reduced mobility status it may at any time increase the number of

those patients. The impact of this approach will be that most health

care facilities will be rated in the "not mobile" risk category.

Mobility Status - Patient mobility status is based on the capability of

each patient to take actions necessary to protect himself. The four

classes are defined as follows:

A. Mobile - Capable of readily rising from bed and taking self-protecting actions at approximately the same rate as a healthy adult.

In order to be classified as mobile the patient must not require

assistance in getting out of bed and must be able to open a closed

or locked door. Mobile persons when sleeping shall be considered

as mobile if they are not restrained or in any other way reduced in

response capabilities so that the type of arousal mechanism that

would normally awaken an adult would not be affected.

D-2
Limited Mobility - Those patients who have all of the capabilities

of a mobile person except that their rate of travel will be significantly less.

C- Not Mobile - Incapable of removing themselves from danger exclusively by their own efforts. Examples would include persons who

are totally bedridden, who require assistance to get out of bed or

to move, or who are restrained, locked in their rooms, or otherwise

prevented from taking complete emergency self protection evacuation

actions without assistance. Mobility status should be based on the

minimum level of mobility in an average 24 hour period.

D. Not Moveable - Not capable of being moved from the room in which

they are housed through the course of a fire. Examples would

include patients attached to life support systems or involved in

medical or surgical procedures that prohibit their immediate relocation

without extreme danger of death or serious harm.

2. Patient Density

The occupancy risk evaluation for occupancy density (number of patients

within the zone) measures both the inherent increase in the maximum fire

death potential that occurs as the number of patients in a zone increases,

and the problems involved by a limited staff in handling larger numbers

of patients during an emergency.

Patient Factor - The density of patients is the number of patients that

could potentially be housed in the zone. The patient count should be

based on the number of assignable beds in the zone on the assumption

that they may all be occupied at the time of the fire emergency.

3. Zone Location

This risk factor relates to fire department accessibility to a fire. The

rating system recognizes the inherent advantages of a first floor zone.

It also recognizes the problems of evacuation from higher floors and the

virtual impossibility of using external fire fighting efforts above the

6th floor in any building.

Floor Factor - The measured zone's location shall be considered to be on floor 1 if the floor has direct access to the exterior at or within less

than 1/2 floor height above or below grade. If a building is on a sloping grade, each floor that has such exterior access shall be considered

as a first floor situation for measurement of fire zones on those floors.

The measured zone shall be considered on the second to third floor

range, the fourth to sixth floor range, based on the height of the zone above the nearest grade floor. The zone shall be considered to be above

the sixth floor if it is more than six floors above the nearest grade

floor. The risk factor value for zones in basements is the same as for zones at or above the 7th floor. The problems involved in emergency

internal access, fire fighting and rescue, and the inability to make

D-3
external attack in basements is approximately equivalent to that in

upper stories of buildings.

4. Ratio of Patients to Attendants

This risk factor recognizes the importance of patient safety of a staff

immediately available to respond in an emergency. The emergency actions

that may be undertaken by the staff include detection, alarm, fire

extinguishment, confinement of the fire, establishing barriers between

the patients and the fire (closing patient room doors), rescue, emergency

medical aid, and other related functions. A few of these functions,

such as detection and alarming, may not be critically related to the

ratio of nursing staff to patients while those related to rescue and the

closing of patient room doors have a strong relationship to the staffing

ratio. The staff ratio considered is based on the minimum staffing

level immediately available (normally night hours)

.

Patients-Attendants Factor - The ratio of patients to attendants is

based on those patients in the fire/smoke zone and the immediately

available attendant staff. In calculating the ratio it shall be based

on the minimum staffing level (usually occurring in the night shift).

Where nursing stations or other positions of attendants are located at

the junction of two or more zones and the location of the station is

such that each of the zones has immediate access and view of the nursing

station, then the total staffing assigned to the nursing station can be

credited to each of the zones. An exception is where staff members are bound by duty assignments (cardiac care units, infant nurseries, operating suites, etc.) that prevent them from responding to other than

their assigned zone.

The evaluation system assesses a charge of 4.0 to this risk factor in

any case where there are periods when there are no attendants immediately

available to a zone that houses patients.

5. Patient Average Age

This risk factor recognizes the increased susceptibility of the elderly

and of infants up to one year of age to physical harm by smoke particles,

gaseous combustion products and heated air. This rating assigns a larger risk factor to zones occupied by a population whose average age

is above 65 or below one year. Basically, imposition of this charge

demands additional safety protection in nursing homes for the aged and

nurseries

.

Age Factor - The mode value is rsed to arrive at the age factor for the

patients in the zone. The calculation should be based on the past

record of occupants assigned to the zone. Patients under one year old

are classified at the same risk level as those over 65. This is in

recognition of the fire susceptibility of infants.

D-4
Table 4

Safety Parameters (General Discussion) - The safety parameters are a measure of those building factors that bear upon or contribute to the

safety of those persons (patients, staff, visitors, others) who may be

in the particular zone at the time of a fire.

Each of the safety parameters are analyzed. Where the current Code

requirements recognize several different approaches to the parameter,

the most important alternatives were listed. In addition, conditions

likely to be encountered in situations failing to meet the explicit Code

requirements, and conditions exceeding those required by the Code but

available for increased protection were also listed.

1. Construction

Construction types are classified in accordance with the definitions of

NFPA Standard No. 220 (1961 edition). Table D-l is an abstract of the

specific framing and material requirements for each of the classes of

construction noted.

The requirements of NFPA Standard No. 220 for "interior partitions

enclosing stairways or other openings through floors" are not to be

considered in the construction classification. These floor openings and

their protection are separately evaluated under safety parameter 7,

Vertical Openings.

Where the facility includes additions or connected structures of different construction the rating and classification of the structure shall

be based on (a) separate buildings if a two hour or greater fire resistive

separation exists between the portions of the building and on (b) the

lower safety parameter point score involved if such a separation does

not exist.

The floor level used to determine the parameter value is the floor of

the fire zone being evaluated. The "Floor of Zone" is the story height

above the floor of lowest exit discharge.

When the zone is on a floor below the floor of lowest discharge, the

construction value shall be based on the distance of that floor from the

closest level of discharge, i.e.: one floor below discharge = "Second";

two floors below discharge = "Third"; three or more floors below discharge

= "Fourth and above."

2. Interior Finish (Corridor and Exit)

The classification of flame spread for corridor and exits is in accordance with the categories specified in the Life Safety Code and defined

in Table D-2. The flame spread classification shall be based on the

most combustible surface after deleting trim. No allowance is made in

the Safety Parameter Values for Class D or E interior finishes. It is

not anticipated that such material will be used in health care facilities.

In the rare case such high flame spread interior finish material is

involved an individual appraisal, outside the capability of this evaluation

system, will be required.

D-5
3. Interior Finish (Rooms)

The same classification of interior finish applies to rooms as to corridors

and exits. The specific definitions are in Table D-2. The flame spread

classification shall be based on the most combustible surface after

deleting trim. No consideration is included in the Safety Parameter

Values for Class D or E interior finishes. It is not anticipated that

such material will be used in health care facilities. In the rare case

such high flame spread interior finish material is involved an individual

appraisal outside of the capability of this evaluation system will be

required

.

4. Corridor Partitions/Walls

For the purpose of this evaluation, the fire resistive partitions con- sidered are solely those between use areas and the corridors. All elements | of the partition, except the door (considered as a separate element in

this evaluation), must be included in the determination of its timerated fire resistance classification, according to NFPA 251. See Table

D-3. An exception to the general rule of evaluating doors separate from

walls occurs when one or more rooms has no door (see Safety Parameter

5) . In this instance it is considered that the worth of the fire resistance

capabilities of the corridor partition wall is so reduced that the wall

should be graded as having no fire resistance. The mechanism for doing

this is incorporated into the Fire Safety Evaluation Worksheet.

Walls shall be considered as incomplete if they have unprotected openings

(louvers, gaps, transfer grills) between the floor and the ceiling, or have ordinary glass lights.* If openings exist above the ceiling level

(or even if the partitions stop at the ceiling level) the walls shall be

considered as complete if the ceiling within the fire/smoke zone is of

monolithic constructions designed to resist the passage of smoke and

there is a smoke tight joint between the top of the partition and the

bottom of the ceiling. The fire resistive rating in this parameter

shall be based on the lowest fire resistance level involved in the

corridor partition or the monolithic ceiling. In such cases the ceiling

and the corridor walls jointly perform the fire and smoke barrier functions

normally expected of a corridor wall which extends from the floor slab

to the underside of the floor or roof slabs above.

Walls shall be considered to have less than a 1/3 hour fire resistance

rating if they are not equivalent to 1/2 inch gypsum wall board on both

sides of studs (even if they extend at least from floor to ceiling) or

if they are not continuous above the ceiling to the underside of the

floor or roof (or floor or ro^ f issembly) above, through any concealed

space such as above a suspended ceiling and through interstitial structure

*Ordinary glass lights shall not be considered as making a partition

incomplete in locations where both sides of the glass light are fully

protected by automatic sprinkler systems.

D-6
and mechanical spaces. Partitions shall also be rated as less than 1/3

hour if they are not incomplete but other defects are involved or the

criteria in Table D-3 are not met.

Fire resistive partitions shall be considered as between 1/3 and 1 hour

if they meet all the criteria for continuity of construction and the

criteria of Table D-3 and have a fire resistance of between 20 minutes

and 1 hour

.

5. Doors to Corridor

The classification of doors to the corridor shall be based on the minimum

quality of any door in the zone and the classification shall be determined

in accordance with NFPA 252. Doors for protection of hazardous areas

and stairwells are not included in this evaluation. They are covered

separately in safety parameter items 7 and 8.

A. No Door - A room shall be considered as not having a door if there

is no door in the opening or if there is some other mechanism which

prevents closing of the door or otherwise leaves a significant

opening between the patient room and the corridor. Doors with

louvers or ordinary glass lights* shall be classified as "no door".

Doors which have been blocked open by door stops, chocks, tie backs

or other devices which require manual unlatching or releasing

action to close the door shall be classified as "no door". Also

doors that are not provided with a latch or other device suitable

for keeping the door tightly closed shall be classified as "no

door".

B. Door Less than 20 Minutes of Fire Resistance - Doors which are not

deficient as described in A, but which do not meet the requirements

for C below, will be classified as less than 20 minutes of fire

resistance

.

C. Door 20 Minutes or More Fire Resistance - Doors shall be considered

as having 20 minute or greater fire resistance if they are of 1

3/4" thick solid core wood construction or any other arrangement of

equal or greater stability and fire integrity. The thermal insulation capability of the door is not considered. Hollow or sheet

steel doors therefore meet the 20 minute requirement.

*0rdinary glass lights shall not be considered as making a partition

incomplete in locations where both sides of the glass light are fully

protected by automatic sprinkler systems.

D-7
D. 20 Minutes or More Fire Resistance and Automatic Closing - Automatic closing devices shall be considered present if the door has

an arrangement which holds them open in a manner such that they

will be released by a smoke detector operated device (e.g. magnetic

or pneumatic hold open device) prior to the passage of significant

smoke from a room of fire origin into the corridor or from the

corridor into a room not involved in the fire. Smoke detectors for

operation of such doors may be integral with the door closers,

mounted at each opening, or operated from systems meeting the

requirements for 2 or more point credit under parameter item 12,

Smoke Detection and Alarm. The requirement for 20 minutes of fire

resistance is the same as in C above.

Self Closing Patient Room Doors - Traditional self closing doors on individual patient rooms shall be evaluated in the following manner:

1. If it can be established that the doors are constantly kept in

the normally closed position except when persons are actually

passing through the openings the self closing device shall be

considered as equal to an automatic closing device and credited

accordingly.

2. If the self closing doors are blocked open they shall be classified

as "no door" and a charge of (-10) invoked.

6. Zone Dimensions

Zone length is the greatest straight line dimension of the fire/smoke

zone. (See paragraphs 10-1311 (b) and 10-2311(b)).

The length of a corridor "dead end" shall be measured from the point at

which a person egressing from the dead end would have an option of

egressing in two separate directions.

In assessing the values for this parameter, a single value will be

chosen based on the poorest safety level in the zone. For example, if one or more dead ends in excess of 30 feet exists, the charge for dead

ends (-4) shall be applied regardless of the actual corridor lengths.

Since dead end corridors and single emergency movement routes (covered

in item 10, Emergency Movement Routes) will each confine the occupants

of a fire zone to a single means of egress, the charges for these two

items are not cumulative. As indicated by the footnote on the safety

parameter values page in the 17 i e Safety Evaluation Worksheet, the

charge for dead end corridors is to be a value of 0 instead of either

(-4) or (-6) in the special case where a charge of (-8) is assessed

under item 10 for single emergency movement routes.

7. Vertical Openings

These values apply to vertical openings and penetrations including exit

stairways, ramps and other vertical exits of the type recognized

D-8
by the Life Safety Code, pipe shafts, ventilation shafts, duct penetrations,

and laundry and incinerator chutes. Enclosures shall be of construction

having fire resistance not less than that prescribed for vertical openings

(see safety parameter item 7). In addition, they shall be equipped with

fire doors or acceptable protection of openings into the shafts all so designed and installed as to provide a complete barrier to the vertical

spread of fire or smoke. A vertical opening or penetration shall be

classified as open if it is: (a) unenclosed; (b) is enclosed but does

not have doors; (c) is enclosed but has openings other than doorways;

(d) is enclosed with cloth, paper or similar materials without any

sustained flame stopping capabilities.

Where vertical openings are located outside the fire/smoke zone and the

separation between the zone and vertical opening is of 1-hour or greater

fire resistance and is of higher fire resistance than the protection of

the vertical opening itself, (for example: an open shaft separated from

the zone by a two hour fire resistive partition with Class B self closing

fire doors) the rating of this factor for the zone being measured shall

be based on the higher of the two fire resistant categories. In the

above example, a safety parameter value of 3 would be given for the two

hour fire resistance. When this occurs however the space within the

vertical opening cannot be considered as an exit route or refuge area

for that zone when considering safety parameter 10, Emergency Movement

Routes

.

A vertical opening shall be considered as open for greater than three

floors if there is unprotected penetration of four or more floors on the same shaft without an intervening slab or other cutoff. (Also see same area as an unprotected penetration covered in the discussion of item 13,

Automatic Sprinklers). If a shaft is enclosed at all floors but one and

this results in an unprotected opening between that shaft, and one and

only one fire/smoke zone the parameter value assigned for that shaft

opening in that fire/smoke zone shall be zero [0],

8. Hazardous Areas

Hazardous areas protection is determined in accordance with Section 6-5

of the 1973 Life Safety Code. In assessing the charge for hazardous

areas only one charge shall be made. It shall be the most severe charge

corresponding to the deficiencies present. A double deficiency can exist only where the hazard is severe and the space is not sprinkler

protected. Double protection consists of both a fire resistive enclosure

and automatic sprinkler protection of the hazardous area. If both of

these are lacking for a severe hazardous location, the double deficiency

charge shall be made. If double deficiencies exist both in the zone and

outside the zone, the higher charge (-11) for the condition inside the zone shall be made. The charges are not cumulative regardless of how

many hazardous areas are present.

D-9
Where the hazard is not severe, the maximum deficiency that can occur is

a single deficiency which may be countered by either a fire resistive

enclosure or automatic extinguishment equipment.

A single deficiency situation will also be considered to exist when a severe hazard is either protected by automatic extinguishing systems or

by fire resistive enclosure but not by both.

The term "Adjacent Zone" as used in the evaluation form means any zone,

either on the same floor or on the floor immediately below, that physically

abuts the zone being evaluated and is not separated by two hour fire

resistive rated construction.

The term "Outside Zone" as used in the evaluation form means any place

within building other than the fire/smoke zone being measured.

Table D-4 is abstracted from paragraph 10-1371 of the 1973 Life Safety

Code and provides guidance in identifying hazardous and severely

hazardous areas.

9. Smoke Control

Smoke Control - The smoke control definitions are as follows:

A. No control . There are no smoke barriers (or horizontal exits) on the floor and there is no mechanical smoke control system.

B. Smoke partition . A smoke partition consists of a partition extending

across the entire width of the zone equipped with doors that are either self closing or are closed upon detection by smoke detectors

located at the door arches or other release mechanism as described

in paragraph 5-2134. To be credited as a smoke partition an existing partition must also conform with the requirements of

paragraphs 10-2312 through 10-2315 of the Life Safety Code.

New smoke partitions in either new or existing buildings must meet

the more stringent requirements of paragraphs 10-1313 through

10-1318 of the Life Safety Code. A horizontal exit will act as a smoke partition and is credited as both a smoke partition (item 9)

and an emergency movement route (item 10)

.

C. Mechanically assisted systems - by zone . Mechanically assisted

smoke control on a zone basis must include a smoke partition as in

B above supported by a mechanism of automatic controlled fans,

smoke vent shafts, or a combination thereof to provide a pressure

differential that will .s^ist in confining the smoke to the zone of

origin. The fans involved may be special smoke control fans or special adjustment of the normal building air movement fans.

D. Mechanically assisted systems - by corridor . Mechanically assisted

smoke control on a corridor basis is a system initiated by a method

of smoke detection that will assure operation of the smoke control

system before significant smoke has entered into the corridor of

the zone. The mechanism must be capable of pressurizing the corridor

in the zone sufficiently to prevent smoke from the room of origin

entering the corridor through the entire course of the fire.

D-10
For such a system to be effective it must be able to hold back the

smoke through the expected maximum severity of the fire. This type

of smoke control system must also have the capability of evacuating

smoke from the corridor on the presumption that the emergency

evacuation procedures and other activities involving the opening

and closing of doors will cause occasional brief periods of overpowering

of the smoke control system and movement of smoke from the fire area into the corridor. This would normally necessitate early

warning smoke detectors, automatic door closers, and/or sprinklered

protection. Where such is the case the individual credits for each

of the involved protection devices are additive to the credits for

the smoke control system.

10. Emergency Movement Routes

A movement route is any means of egress meeting the requirements for

such means in Sections 5-3 through 5-10 of Chapter 5 of the 1973 Life

Safety Code excluding only fire escapes, fire escape ladders Section 5-

92 and slide escapes 5-93. Horizontal exits shall also meet the requirements

stated below. Doors exiting directly to the exterior shall also constitute

a movement route for the room containing such a door.

A. <T 2 Routes - The emergency movement means from a zone is classified

as less than two routes if there are not two or more movement

routes serving it. Movement routes may be outside the physical

limits of the zone.

B. Multiple Routes - The emergency movement route is multiple if the zone occupants have the choice of two or more distinctly separated

movement routes from the zone.

C. Deficient Capacity - The egress route shall be considered as deficient in capacity if the door to a patient room or passage

through a smoke barrier is less than 34" (44" in new buildings) in I clear or if the corridor in the zone between patient rooms and

smoke barriers and exits is less than 48" (8 feet in new buildings) | in clear width. These figures are based on the minimum width for a wheelchair to egress a room and the minimum width for the passage

of a wheelchair in one direction and an ambulatory person in the

opposite direction. Exit routes shall also be considered deficient

if any of the dimensional details are less than that required by

the Life Safety Code for the egress route involved. However any

route where the doors from rooms or through partitions or walls are less than 32 inches in the clear, where the corridor (s) involved i are less than 34 inches wide or where stair or stair access is less I than 28 inches in the clear shall not be credited as an egress

route. Exit routes shall also be considered deficient in capacity

if they are not provided with emergency lighting in accordance with

Section 10-2271.

D-ll
D. Horizontal Exit - The presence of a single horizontal exit from the zone being evaluated shall be considered meeting this requirement

provided the space on the opposite side of the horizontal exit is

capable of handling all of the patients from affected zones. To be

credited as a horizontal exit the existing arrangement must also

conform with the requirements of 10-2261 of the Life Safety Code.

New horizontal exits in new or existing buildings must meet the

more stringent requirements of paragraph 10-1261 of the Life

Safety Code.

E. Direct Exits - To be credited with direct exits, each patient use space (except bathrooms, restrooms, and corridors) in the zone shall have a door operable by the room occupant (s) that opens

directly to the exterior at grade or onto an exterior balcony with

direct access to an exterior exit or a smoke proof tower. To be

credited, the direct exit must be ramped or otherwise without steps

or changes in elevation that would prevent or obstruct the movement

of wheelchairs or wheel littered patients through the direct exits

to a place of safety and refuge.

11. Manual Fire Alarm

The manual fire alarm systems for new construction shall be in accordance

with the requirements of paragraphs 10-1361 and 10-1284. Existing

construction shall be in accordance with paragraph 10-2351. Connection

to the Fire Department shall be considered as being met if the fire

alarm system is connected directly to the Fire Department, through an approved central station, or through other means acceptable to the

authority having jurisdiction.

12. Smoke Detection and Alarm

A detection system as used here is one based on use of smoke detectors.

No recognition is given for thermal detectors. The detection system

categories are as follows:

A. None - There are no smoke detectors in the zone.

B. Corridor Only - Smoke detectors located in the corridor shall be

considered as meeting the requirement if the detectors are within

15 feet of each end of the corridor and not more than 30 feet apart

throughout the corridor. All such detectors shall be electrically

interconnected with the fire alarm system. If the facility does

not have a fire alarm system, no credit shall be given to the

detectors unless they include an alarming system that meets the

requirements for alarming that would be involved with a manual fire

alarm system. This includes audible alarm devices throughout the

building.

D-12
c. Rooms Only - Smoke detectors shall be considered as meeting this

requirement when there is at least one smoke detector in each room occupied or used by patients. In rooms having a dimension in excess of 30 feet additional detectors shall be provided so that

detector spacing does not exceed approximately 30 feet. Detectors

are not required in restrooms or closets. Detectors intended for

operation of door closing mechanisms that are located on the patients'

side of the door or in the door opening are considered as meeting

this requirement for rooms of 500 square feet or less.

Corridor and Habitable Spaces - Detection systems installed throughout the corridors of the zone involved and in the habitable spaces

(patient rooms, nurses stations, and other areas basically used for

human occupancy) shall be considered as meeting the requirements

for a corridor and habitable spaces detection system. Closets,

toilet rooms, and other auxiliary spaces as well as ceiling voids,

interstitials and other building space not used by humans as a normal part of their regular occupancy are not required to have

detectors

.

E. Total Zone - Total zone provision of detectors includes detector

coverage of all spaces except noncombustible building voids which

contain no combustible materials. The total zone credit is to be

given if the zone measured meets this criteria regardless of the

presence or lack of detectors in other portions of the building.

13. Automatic Sprinklers

In evaluating sprinkler protection within the zone, the protection or lack of protection of hazardous areas is considered separately and

covered under safety parameter 8. For all other areas in the zone,

sprinklers shall be graded on the following basis:

A. None - No charge is applied if there are no sprinklers or if

sprinklers, though present, are not sufficient to qualify for one

of the other categories listed herein.

B. Corridor * - The safety parameter value of 2 for corridor sprinklers

is to be awarded only where the corridor is protected by a specially

designed corridor system in which the sprinkler heads are placed

according to their individual spray patterns and in consideration

of the flow hydraulics of the sprinkler system. This special

design must assure that there is an automatic sprinkler head outside

each patient room so positioned that the spray pattern from that

head will completely cover the entrance to the protected doorway.

This degree of sprinkler protection is based on the amount of

sprinkler protection in the measured zone whether or not areas outside the fire zone are similarly protected.

*Corridor sprinkler protection is credited only in buildings classified

as "protected" or "fire resistive" in safety parameter no. 1, Construction.
C. Corridor and Habitable Space* - This credit is based on standard

sprinkler spacings in the areas covered and is conditional on the

classification of construction type as covered in Safety Parameter

Item 1, Construction, as follows:

1 . Item 1, Construction, is based on a "Protected" or "Fire

Resistive" type of construction. This credit is based on a system

that effectively provides coverage for all corridor and habitable

space in the zone plus the establishment of water distribution

patterns or other protection in a manner to prevent advance of fire

from non-sprinklered spaces into the sprinklered spaces. In buildings

of protected or fire resistive construction, the credit is to be

applied to any zone where the above conditions are met whether or not areas outside the zone are similarly protected.

2 . Item 1, Construction is based on an "Unprotected" type of

construction . In any unprotected type of construction the credit

for the corridor and habitable space protection is to be given only

if, in addition to the conditions described in (1) above, sprinkler

protection is also provided in all spaces in the building (including

attic or loft spaces) with construction elements that are not

sheathed, enclosed, or otherwise protected with fire resisting

materials such as gypsum board, plaster, or masonry block.

D. Total Bldg. - Total bldg, automatic sprinkler protection is to be I credited only if the entire structure is protected by automatic

sprinklers in accordance with Section 6-41 of the Life Safety Code.

Wherever sprinkler protection is involved in an area having an unprotected

vertical opening, the sprinkler protection around that vertical opening

must conform with one of the approved methods outlined either in Chapter

6 of the Life Safety Code or in NFPA Standard No. 13. This protection

is required to allow the credit for sprinkler protection but shall in no way reduce any change under safety parameter 7 resulting from an unprotected

vertical opening.

In Table 5 of the Fire Safety Evaluation Form, (Individual Safety

Evaluations) the value for sprinkler protection credited to the people

movement safety (S3) category is divided by 2. This produces a safety

value only 1/2 the value credited in other categories. This is in

recognition of the ability of sprinkler protection to control, confine,

and frequently extinguish fire while recognizing its limitation in

preventing or controlling the spread of smoke.

*Habitable space includes patient rooms, nurses stations, and other

areas basically used for human occupancy. Habitable space does not

include closets, bathrooms, and toilets, elevators, and similar spaces.

D-14
Each sprinkler system shall be provided with supervision. Each sprinkler

system shall be electrically inter-connected with the fire alarm system

and the main sprinkler control valve shall be electrically supervised so that at least a local alarm shall sound in a constantly attended location

when the valve is closed.

D-15
Table D-l Construction Types

The construction types are defined per NFPA 101 reference to NFPA 220-

1961 edition. They consist of:

a. Wood Frame Construction (Unprotected)

Definition - That type of construction in which exterior walls,

bearing walls and partitions, floor and roof constructions and

their supports are of wood or other combustible material, when the

construction does not qualify as Heavy Timber Construction, Ordinary

Construction, or Protected Wood Frame Construction.

b. Protected Wood Frame Construction

Definition - Wood Frame Construction may be designated Protected

Wood Frame Construction when roof and floor construction and their

supports have one-hour fire resistance. i

c. Ordinary Construction (Unprotected)

Definition - That type of construction in which exterior bearing

walls or bearing portions of exterior walls are of noncombustible

construction having a minimum fire resistance of two hours and

stability under fire conditions; non-bearing exterior walls are of

noncombustible construction; and in which the roofs, floors and

interior framing are wholly or partly of wood (or other combustible

material) of smaller dimensions than required for Heavy Timber

Construction. Fire resistance may be required for non-bearing

exterior walls, and fire resistance additional to that specified

may be required for bearing walls or bearing portions of walls, by

conditions such as occupancy, location with respect to lot lines,

fire exposure and other pertinent conditions.

d. Protected Ordinary Construction

Definition - Ordinary Construction may be designated Protected

Ordinary Construction when roof and floor construction and their

supports have one-hour fire resistance.

e. Noncombustible Construction (Unprotected)

Definition - That type of construction in which the walls partitions

and structural members are of noncombustible construction not

qualifying as Fire Resistive Construction or Protected Noncombustible

Construction.

D-16
Table D-l Construction Types (Continued)

f. Protected Noncombustible Construction

Definition - Noncombustible Construction may be designated Protected

Noncombustible Construction when bearing walls or bearing portions

of walls, exterior or interior, are of noncombustible construction

having a minimum fire resistance rating of two hours and are stable

under fire conditions; roof and floor construction and their supports have one-hour fire resistance.

fire resistance.

g. Fire - Resistive Construction

Definition - That type of construction in which the structural

members including walls, partitions, columns, floor and roof

constructions are of noncombustible materials with fire resistance

ratings not less than those specified in the following table.

Table D-2 Flame Spread Classification for Wall and Ceiling Finishes

Flame Spread - The surface flame spread rating of ceilings and walls as measured by ASTM E-84. The categories of flame spread are:

Class A Interior Finish. Flame Spread 0-25. Includes any material

classified at 25 or less on the test described above. Any element

thereof when so tested shall not continue to propagate fire.

Class B Interior Finish. Flame Spread 26-75. Includes any material

classified at more than 25 but not more than 75 on the test described

above

.

Class C Interior Finish. Flame Spread 76-200. Includes any material

classified at more than 75 but not more than 200 on the test scale

described above.

Existing floor covering materials in existing buildings are not to be

considered in classification of interior finish. Floor covering material

in new buildings shall be considered as Class A in rating interior finish

in Table 4, Items 2 and 3, if they are of either Class A or Class B rating

If not the rating shall be based on the actual class of the floor covering

material

.

No change or adjustment in the above classifications is to be made even

if the space is sprinkler protected. The impact of sprinkler protection

is separately accounted for in Item 13 of figure 4.

D-19
Table D-3 Fire Resistive Partition Details

Transfer grills, whether protected by fusible link-operated dampers or not, shall not be used in these walls or doors. Fixed wired glass

vision panels may be placed in corridor walls, provided they do not

exceed 1,296 square inches in size and are installed in approved steel

frames. Fixed wire glass vision panels may be installed in wood doors,

provided they do not exceed 720 square inches in size and are installed

in approved steel frames.

Waiting areas of 250 square feet or less on an institutional sleeping

floor may be open to the corridor, provided that they are located to

permit direct supervision by the institutional staff. Such areas shall

be equipped with an electrically supervised automatic smoke detection

system installed in accordance with paragraph 10-1362 of the Life Safety

Code. Not more than one such waiting area is permitted in each smoke

compartment

.

Waiting areas of 600 square feet or less on floors other than institutional sleeping floors may be open to the corridor, provided that they

are located to permit direct supervision by the institutional staff and

so arranged as not to obstruct any access to required exits. Such areas

shall be protected by an electrically supervised automatic smoke detection

system installed in accordance with paragraph 10-1362 (10-2.3.3.6) of

the Life Safety Code.

APPENDIX F

COMPUTER PROGRAM

F-l Program Description

The computer program* was developed to support the proof testing

efforts of the evaluation system. The program is basically a research

tool and not a production tool. It is designed to be used in determining

how best to upgrade a health care facility to an acceptable level of

safety. The user inputs one or more values for each of the 13 safety

parameters. The program examines all possible combinations of these

numbers, one value per parameter, and finds those combinations which

would upgrade the safety of the facility if implemented. The solutions,

or successful combinations, may be sorted by a particular parameter if

the user wishes, in which case up to 1000 solutions may be printed for

each value of the sorting parameter.

As presently written, the program searches for up to 50 000 solutions

for each specified value of the sorting routine, limiting the output for

each value to at most the first 1000 solutions. A special input card

overrides the sorting feature, allowing a change in the total printed

output to any number less than 1000 solutions. A limit on the available

combinations, or zone configurations, may be accomplished by limiting

the number of potential combinations when inputing the parameters, or by

choosing "close" upper and lower limits for the total safety values. In

the latter method a difference of two points gives a reasonable number

of possible solutions. In addition, the special sorting routine provides

the capability of analyzing zone configurations which are limited to

certain characteristics.

F-2 Input Requirements

To operate this program a series of input information is required.

The information must be key punched on computer cards. The total number

of input cards is 18. The following is a description of the input

cards

:

The maximum mandatory values

must be equal or larger than

the minimum mandatory values

Follow the format as defined for card #17.

F-3 Example

A typical example of the program output is shown in table F-l. For

more information see figures E-1A - E-ID. An analysis was performed to

evaluate zone configurations for a new facility. It was assumed that

the zone had a dead end which was longer than 100 feet; all hazardous

areas were secure and had sprinklers in the corridors and habitable

spaces. The zone was on the 4th floor of the building. The general

safety level was estimated to be 15. The minimum containment, extinguishment and people movement safety values were taken from table 6, for a zone located above the first floor in a new building. The maximum

safety values were estimated to have a differential value of two points

(this provides enough differential for analysis). All zone configurations

shown in table F-l have safety levels which are greater than or equal to

the four corresponding specified minimum safety values but which are not

all greater than the four corresponding specified maximum safety values.

The extended analysis was performed primarily to examine the range of

permissible solutions corresponding to five levels of the smoke detection

and alarm parameter.

16. ABSTRACT (A 200-word or leaa factual summary of moat aighificant information. If document includes a significant bibliography or

, literature aurvey, mention U here .1 r - , - - , ...... . _ _ . A quantitative evaluation system for grading health care facilities in terms of fire

safety is described. The system can be used to determine how combinations of widely

accepted fire safety equipment and building construction features may provide a level of

safety equivalent to that required by the widely accepted Life Safety Code of the National Fire Protection Association. The system will provide flexibility to both the designer of new facilities and to the renovator of existing health care facilities. Three

major concepts form the basis for code equivalency: a. Occupancy Risk - the number of

people affected by a given fire, the level of fire they are likely to encounter and

their ability to protect themselves; b. Building Safety Features - the ability of the

building and its fire protection systems to provide measures of safety commensurate witf

the risk; c. Safety Redundancy - in-depth protection, through the simultaneous use of

alternative safety methodologies such as containment, extinguishment, and people movement methodologies. The design of the complete fire safety system is intended to en- sure that the failure of a single protection device or method will not result in a major

failure of the entire system. In this system, equivalency is judged to exist when the

total impact of the occupancy risk factors and the compensating building safety features

produce a level of safety equal to or greater than that achieved by rigid conformance tc the explicit requirements of the NFPA Life Safety Code. In this evaluation, safety performance is gauged both in terms of overall safety impact and depth of redundance.
