EXECUTIVE SUMMARY

Introduction

The objective of this manual is to provide local and state fire agencies 

with the specifications necessary to develop version 5.0 of the National Fire Incident Reporting System (NFIRS). To meet this objective, three 

major sections are included in this document. 

•	 Overview of the NFIRS 5.0 System

•	 Data Dictionary, Edits and Transfer File Specifications

•	 System Implementation Guide

One critical success factor in establishing an all-incident NFIRS is a complete system specification that is accepted as the national standard for fire 

incident reporting. This document serves as both a national standard and 

a guide for implementing NFIRS 5.0 at the local and state levels.

NFIRS 5.0 is designed to be a modular, all-incident reporting system. The 

system was designed by the United States Fire Administration, a part of 

the Federal Emergency Management Agency. 

How NFIRS Works

NFIRS is jointly managed by the U.S. Fire Administration (USFA) and the 

National Fire Information Council (NFIC). NFIC is a users’ group comprised of volunteers who donate their time to maintain the existing system and to research and implement changes to improve it. The members 

of NFIC are representatives from state agencies and large metropolitan areas 

that are responsible for incident data collection and analysis. As federal budgets have been reduced, the role of NFIC has expanded. Due to the extraordinary commitment of the members of this council, as well as the ongoing 

support of USFA, NFIRS is able to maintain its high level of performance.

As critical a role as the members of NFIC play, the heart of the system is 

dispersed across the country, in the 14,000 fire departments that participate 

in NFIRS. After responding to an incident, fire department personnel fill 

out the appropriate NFIRS modules. These describe the nature of the call, 

the actions firefighters took in response to the call, and the result. The latter 

includes the number of civilian or firefighter casualties and an estimate of 

property loss. While specific modules filled out by a local fire department 

may be state-specific, they contain a core of information common to every 

state’s reporting system. The uniformity of definitions used in coding these 

fields makes aggregation of national data possible.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

EXECUTIVE SUMMARY

2

Local agencies forward the completed NFIRS modules, which are filled 

out either manually or via computer, to the state agency responsible for 

NFIRS data. The state agency combines the information with data from 

other fire departments into a statewide database and then electronically 

submits the data to the National Fire Data Center (NFDC) at the U.S. 

Fire Administration. The NFDC can then compare and contrast statistics 

from states and large metropolitan departments to develop national public education campaigns, make recommendations for national codes and 

standards, guide allocation of federal funds, ascertain consumer product 

failures, identify the focus for research efforts, and support federal legislation. The annual NFIRS data are used as the basis for the U.S. Fire Administration’s publication Fire in the United States, which is the single most 

comprehensive reference on the nature and scope of the fire problem in 

the U.S.

At the national level, data combined from participating states is also used 

by information partners, including:

•	 U.S. Consumer Product Safety Commission (CPSC)

•	 International Association of Fire Chiefs (IAFC)

•	 International Association of Firefighters (IAFF)

•	 National Association of State Fire Marshals (NASFM)

•	 National Fire Protection Association (NFPA)

•	 National Highway Traffic Safety Administration (NHTSA)

•	 National Volunteer Fire Council (NVFC)

The Benefits of NFIRS to Firefighters

The new system is specifically designed to be more firefighter friendly. Two additional modules, the Apparatus and Personnel Modules, have 

been added to assist fire departments in managing apparatus, personnel, 

and resources.

Every fire department is responsible for managing its operations in such a 

way that firefighters can do the most effective job of fire control and fire 

prevention. Effective performance requires careful planning, which can 

only take place if accurate information about fires and other incidents are 

available. Patterns that emerge from the analysis of incident data can help 

departments focus on current problems, predict future problems in their 

communities, and measure their programs’ successes.

The same principle is also applicable at the state and national level. NFIRS 

provides a mechanism for analyzing incident data at each level to help 

meet fire protection management and planning needs. In addition, NFIRS 

information is used by labor organizations on a variety of matters, such 

as workloads and firefighter injuries.

EXECUTIVE SUMMARY

Coding Background

Incident data collection is not new. Many cities and states have used data 

systems for years—some doing their analyses by hand, some using computer systems.

In 1963, the National Fire Protection Association (NFPA) formed a technical committee to devise a uniform system of fire reporting to encourage fire departments to use a common set of definitions.

A dictionary of fire terminology and associated numerical codes was developed. This dictionary is known as NFPA 901, Standard Classifications for 

Incident Reporting and Fire Protection. As the fire service gained experience with 

this fire data “language,” improvements were made to the system. The 

current set of codes used in NFIRS 5.0 represents the merging of the 

ideas from NFPA 901 and the many suggested improvements from the 

users of the NFIRS 4.1 coding system.

NFIRS Background

In 1972, the President’s Commission on Fire Prevention and Control issued a document entitled, America Burning. This document was the first 

“in-depth” discussion of this country’s fire problem. The outgrowth of 

America Burning was the National Fire Prevention and Control Act, Public 

Law 93-498, which established the National Fire Prevention and Control 

Administration.

One of the results of the Public Law 93-498 mandate to collect national 

data on fires was the establishment of the National Fire Incident Reporting System. In 1976, six states piloted what was to become the National 

Fire Incident Reporting System, or NFIRS. The U.S. Fire Administration 

developed NFIRS as a means of assessing the nature and scope of the fire 

problem in the U.S. 

NFIRS Today

The NFIRS system first came on line in 1976, and since then, it has 

grown in both participation and use. At the time this handbook was being prepared, 42 states and over 14,000 of this nation’s fire departments 

were participating in NFIRS. This makes NFIRS the largest collector of 

fire-related incident data in the world. NFIRS contributes over 900,000 

fire incidents each year to the National Fire Database.

Some states and fire departments are just beginning to participate in 

NFIRS, others have large databases containing several years of data. NFIRS 

data is being used at all levels of government: local, state, and national.

At the local level, incident and casualty module information is being 

used for setting priorities and targeting resources. The data now being 

collected is particularly useful for designing fire prevention/education 

programs and EMS-related activities specifically suited to the real emergency problems the local community is currently facing.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

EXECUTIVE SUMMARY

4

On the state level, NFIRS is being used in many different capacities. One 

valuable way that it has aided the states is through work with the legislature. 

NFIRS has been used to justify state budgets and has helped in the passage of 

important bills on fireworks and arson. As in the local level, the data collected 

is particularly useful for designing fire prevention and education programs.

Nationally, NFIRS has been used by various private industry organizations, 

including national associations for home appliance product manufacturers, 

the hotel and motel industry, insurance companies, attorneys and many others. 

Many other federal agencies (aside from FEMA and the USFA) use NFIRS 

data, such as the Consumer Product Safety Commission, the National Highway Traffic Safety Administration, and the National Institute of Standards and 

Technology. The Consumer Product Safety Commission has found this system very useful in finding products that could be a hazard to consumers. 

With each year, the quality of the available data is improving and new and 

better ways to use it are devised.

What is NFIC?

As the number of NFIRS states and major metropolitan areas increased from 

six initial states to 42 states and 34 major metropolitan areas, it became apparent that some organization was needed to give these NFIRS participants 

a forum to exchange ideas and discuss common problems. The National Association of NFIRS States (NANS) was established in 1979 to provide this 

opportunity. Through continued change and alignment of state and metro 

participation in the overall operation of the NFIRS System, the importance of 

NANS increased.

In 1981, the name of the organization was changed to the “National Fire 

Information Council,” or NFIC. Each state participating in NFIRS has one 

representative in NFIC, as does each major metropolitan area that serves 

500,000 or more people.

NFIC is governed by a board of 15 directors, three from each of four geographical regions and three from metro areas. Members of the board are 

elected at an annual conference. The board acts as a liaison between USFA 

and NFIRS participants for major policy decisions concerning NFIRS operations or support.

History of NFIRS Participation

Because NFIRS is a voluntary system, not all states or fire departments within 

states participate. In 1977, one of the early years of the system, five states 

regularly reported data to the National Fire Data Center, and 19 others had 

data systems in some stage of development. Since then participation has increased to 42 states, and over 14,000 fire departments report to NFIRS. It is 

estimated that 44 percent of all fires to which fire departments respond are 

captured in NFIRS, making NFIRS an extremely large sample of all fires that 

occur each year.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 5

EXECUTIVE SUMMARY

Because states have the flexibility to adapt their state reporting systems to 

their needs, and since reporting by localities is voluntary, the design of a 

state’s data collection system can vary from state to state. However, NFIRS 

was designed so that data from state systems can be converted to a single 

format that is used at the national level to aggregate and store NFIRS data.

The existing NFIRS employs techniques of data entry, validation, transmittal and analysis that represented the state-of-the-art at the time of its 

original design in the late 1970’s. Advances in computer technology have 

now far eclipsed the current NFIRS. Survey feedback from participating 

fire departments, states and vendors has resulted in valuable suggestions 

to improve the system, many of which cannot easily be implemented 

within the current system due to the vintage of its architecture.

the fire service.

NFIRS VERSION 5.0 DESIGN DOCUMENTATION 7

Section 2

SYSTEM OVERVIEW

The Data-based Decision-making Process 

Fire personnel accurately recording the circumstances of all incidents, 

using a reliable and consistent coding methodology, is the first step in 

the data reporting process and a key for developing profiles that affect a 

department’s decisions. Incident data can be used by fire departments to 

document their experience, support all types of management decisions, 

and identify, prepare and justify budget requests.

Local agencies then can send their incident data to the state, where the 

information is combined with data from other fire departments into a 

statewide database. By combining data at the state level, trends in fire 

problems can be detected that are often too infrequent to be seen at the 

local level and a state fire profile developed. Trend information can be 

used to target fire safety and prevention programs, as well as assist in 

identifying the safety level of products and practices. For these reasons, 

fire incident reporting is mandatory in many states.

State incident data is sent to the National Fire Data Center (NFDC) at 

the United States Fire Administration for further analysis. The NFDC can 

compare and contrast statistics from states and large metropolitan departments to develop national public education programs, make recommendations for national codes and standards, guide allocation of federal 

funds, identify consumer product failures, identify the focus for research 

efforts, and support federal legislation, such as the Hotel/Motel Fire 

Safety Act (Pub. L. 101-391 - Sept. 25, 1990).

At the national level, data combined from participating states can be used 

by the information partners. These organizations use national-level fire 

data to establish policy, allocate funds, and set standards to affect the fire 

problem. Decision-making based on incident patterns identifies common areas for prevention and high-risk products, and geographic areas 

so partners can take steps in response.

The purpose at all levels in the data reporting system is to provide timely and reliable information that supports the decision-making process, 

whether it is a fire captain identifying target hazards and properly deploying resources based on incident information, or the CPSC banning 

unsafe products like flammable sleepwear for children.

Consistent response data supports 

local decision making in administration and operations.

State-level data points policymakers to problems that need a 

broadly-based response.

National level data can be used by 

information partners to address 

community risk reduction issues. 

Addressing issues nationally can 

help local emergency responders 

acquire resources to address highrisk issues.

SYSTEM OVERVIEW

The All-Incident Reporting System

The USFA, as well as many states, is mandated by law to collect information on fires, and rely on the nation’s fire service to meet that requirement through the National Fire Incident Reporting System (NFIRS). The 

NFIRS (Version 4.1) cannot adequately meet today’s fire service information needs because it was designed to collect only fire information, 

which represents a fraction of the tasks performed by the fire service. The 

new NFIRS will address the fire service’s need for a system that accounts 

for the full range of fire department incidents.

NFIRS program managers representing 42 states and 34 metro fire departments have learned many lessons about fire reporting during the past 

20 years. With the input of state Fire Marshals, Metro Fire Chiefs, local 

Fire Departments, and customers such as the IAFC, IAFF, NFPA, CPSC, 

and NHTSA, they developed NFIRS 5.0, guided by the following specific 

design objectives.

System Design Objectives

•	 Create an All-Incident Reporting System. To keep pace with the rapidly changing activities of the fire service, NFIRS 5.0 must be designed 

as an “all-incident” system including, but not limited to: Fire, EMS, 

NFIRS 5.0 is based on 20 years 

of experience in data management 

among current NFIRS users, and 

ideas from national fire service 

organizations.

NFIRS 5.0 records information 

about all responses, not just fires.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 9

SYSTEM OVERVIEW

HazMat, Wildland and Arson incidents. Inclusion of new incident 

types must be supported by the NFIRS 5.0 Standard.

•	 Develop a set of reporting codes that can accurately, reliably and easily describe any incident. All data should be readily collectible, reportable and usable. 

•	 Promote uniformity of incident reporting by establishing the NFIRS 

5.0 coding methodology as the accepted national standard, with the 

consensus of the USFA, NFIC, NFPA, IAFC, IAFF, NASFM and other 

information partners.

•	 Make the system hardware platform independent. The NFIRS 5.0 Design Specifications must support the development of a data collection 

system on any hardware platform to ensure its universal acceptance 

and the capability to integrate with existing systems, where needed. 

•	 Make the system application software/database independent. The 

NFIRS 5.0 Design Specifications must support the development of a 

data collection system using industry standard software that is nonproprietary to the specification. This will help to ensure universal acceptance of the NFIRS 5.0 Standard and allow for its integration with 

existing systems.

•	 Map the historical data from the old system to the new system where 

feasible.

•	 Preserve the ability for a state to collect Version 4 or 4.1 incident reports without maintaining a separate database.

NFIRS 5.0 is broadly supported by 

national organizations.

NFIRS 5.0 is flexible and adaptable, working with a variety of 

hardware and software systems, including previous editions of NFIRS.

Benefits

The new system is modular in design and only uses the modules necessary to describe the incidents. Data is collected for all incident types in 

one basic module. More detailed information can be collected with other 

modules to further profile fires, structure fires, civilian casualties, fire 

fighter casualties, hazardous materials, wildland fires, arson, apparatus, 

personnel, and EMS incidents as necessary. 

The modular design makes the system easier to use because only the data 

required to profile the extent of the incident is captured. Accuracy and 

reliability have been improved by modifying the coding system.

Ease of Use

•	 Simplifies look-ups by alphabetizing coding lists with multiple 

choices for the same code. 

•	 Merges the codes ending in 9 and 0. Version 4.1 required a distinction between the codes ending in 9, “not otherwise classified”, and 

the codes ending in 0, “insufficient information to classify further”. 

The proper distinction between these two codes is often not observable in the field. 

A modular design increases the system flexibility, and decreases data 

collection.

Data coding has been revised to 

reduce confusing classifications.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

SYSTEM OVERVIEW

10

•	 Eliminates compound codes. Some of the previous codes have contained embedded multiple questions. NFIRS 5.0 splits these elements, 

since they are often confusing to the reporter and result in ambiguous or erroneous answers. Although this may increase the number of 

fields, the choices will be clearer among alternatives and the number 

of codes are decreased. For example, “Equipment Involved in Ignition” in Version 4.1 is a long, complex list of equipment that includes factors on power source and use. Version 5.0 creates just three 

categories (Equipment, Equipment Portability, and Equipment Power 

Source) to make coding easier, more accurate, and specific.

•	 Provides for abbreviated reporting of self-contained, non-loss fires 

by using a basic incident form that can be completed with as little as 

three look-ups. This may represent the majority of all fire incidents 

in many jurisdictions. 

•	 Abbreviates paths through the system for nuisance fires where there 

have been no losses or casualties. This will eliminate the amount of 

information that needs to be entered into the system.

•	 Documents small spills of common hazardous materials on the basic 

form. More detailed information can be provided on the optional 

hazardous materials module if a serious release of hazardous materials occurs.

Abbreviated reporting for most 

incidents will reduce data collection 

and classification times.

Compatibility

•	 Compatible with current electronic technology. Version 5.0 is designed for electronic media technology. The design specification in 

Section 3 contains specific data libraries, programming specifications, and data flow charts. 

•	 Includes a mapping strategy back to Version 4.1 to provide for statistical analysis of historical data.

•	 Designed to support current and anticipated technologies: clientserver, object-oriented database; and Internet WEB server technology.

•	 Allows for the inclusion of optional state or local data storage and 

retrieval. This data is for use at the local or state level only.

•	 Recognizes that there may be a need for additional data elements to 

meet the local situation.

Comprehensiveness

•	 Collects behavioral information on multiple levels, e.g., children 

playing with fire, age range, what they used to set the fire, and if they 

were alone at the time of the incident. 

•	 Formats the address to allow computerized queries and street-based 

address matching for Geographic Information System (GIS) purposes.

NFIRS 5.0 works with current 

technology and anticipates future 

equipment and software developments.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 11

SYSTEM OVERVIEW

•	 Breaks fire losses into property and contents to better define structure losses. Pre-incident value is also now captured as an optional 

data element.

•	 Captures specific property information about multiple on-site materials and their use. This will allow identification of non-intended or 

illegal uses of property, such as residential drug houses or laboratories.

•	 Notes information on the number of acres burned for all fires. Specific and detailed information about wildland or large open fires is 

captured for those fires only.

•	 Represents missing (not-reported) data as blanks system wide. Missing data will no longer be lumped in with undetermined default 

code values. 

NFIRS 5.0 offers more precise 

information classification.

Reliability 

•	 Profiles fire prevention and code issues that affected the fire.

•	 Captures multiple factors contributing to the causes of the fire for the 

first time. This allows identification of juvenile fire setters, gang involvement in fires, alcohol and cigarette interaction, as well as drugs 

and youth involvement by age categories.

•	 Expands on equipment involved in starting fires. Detailed tracking of 

specific equipment involved in fire ignitions is possible.

•	 Highlights factors that affect fireground suppression. Burglar bars, 

high-rack storage, balloon construction and unprotected vertical 

openings are some examples of this information.

Usefulness

•	 Provides better information on the impact of fire protection features.

•	 Transmits certification of applications with certification numbers to 

the state.

•	 Includes carbon monoxide incidents.

•	 Notes one-time information for special studies purposes.

•	 Groups fire service resources for apparatus and personnel by use at 

the incident. Specific, detailed information about the use of fire service personnel and apparatus will be collected in a standard way for 

the first time in optional modules. This will permit staffing studies 

on several levels of use.

•	 Outlines detailed information on the impact of fires on buildings. Information on the building’s size, number of stories and status is now 

available. Specific information on fire origin, damage patterns, flame 

spread and materials contributing to flame spread is captured as well.

NFIRS 5.0 data fields can capture 

information beyond simple incident 

descriptions.

Administrative information is routinely gathered and classified.

Data fields profile building and systems information that can be used 

to develop prevention strategies.

•	 Expands information on detectors and automatic suppression systems. Information on the system’s presence, range, power supply, effectiveness, operation, and reason for failure is included.

•	 Extends information on casualties to provide a better understanding 

of the relationship of the casualty to factors contributing to injury, as 

well as the nature and cause of injuries.

System Module Overview

Version 5.0 uses a modular format to increase the accuracy and applicability of data collection for all incident types. The overall number of 

data fields has been increased. However, because 5.0 takes advantage of 

selective field entries based on incident type, the number of fields used 

to define an incident has decreased compared to Version 4.1. Version 5.0 

has eleven modules that are described below.

Basic Module (NFIRS-1) 

The Basic Module is used for every incident. This may be the only module necessary for certain incident types such as confined fires, small vegetation fires, outside rubbish fires, explosions, and other incidents classified as “other fire types and non-fires.” This feature satisfies the request 

for short form fire reporting.

TECHNICAL DOCUMENTATION

System Architecture

The NFIRS 5.0 system is implemented as a distributed client-server system using “state-of-the-art” technologies. The system architecture has 

been specifically designed to provide flexibility for the implementation 

of the NFIRS 5.0 system. 

At the core of the NFIRS 5.0 system is a national database server and 

server software that resides on the FEMA WAN. Incident data stored in 

the NFIRS 5.0 system is organized by state and identified as a valid incident through the tools provided by the USFA. States are required to 

‘release’ valid incidents that are available for general use. Some states 

may prefer to store all their incident data on a local database. In this case 

they have the option to upload only the valid incidents to the National 

database server and ‘release’ those valid incidents that are available for 

general use. 

Depending on how a state chooses to implement the NFIRS 5.0 system, 

the components of the system required and the options available for 

those components will vary. The main differentiating factors between 

the scenarios surround where the data is stored and where incident data 

entry takes place. For discussion of the options available to the state, See 

“System Implementation Guidelines” on page 333.

System Note: On January 1, 2009, NFIRS ceased collection of NFIRS 

legacy version 4.1 incidents. Data in the 4.1 format collected after the 

NFIRS 4.1 sunset date are no longer converted and imported into the 

NFIRS database.

Figure 3-1 on page 26 depicts some of the inbound incident collection 

connectivity options available to states and local users.

TECHNICAL DOCUMENTATION

System Modules

The new system is modular in design and only requires the modules 

necessary to describe a particular incident. Data is collected on all incidents in a basic module with additional modules employed to further 

profile fires, structure fires, civilian fire casualties, fire service casualties, 

EMS incidents, hazardous material incidents, fires, apparatus, personnel 

deployment and arson fires.

The following is a brief description of each module used in the NFIRS 

Version 5.0.

The Basic Module (NFIRS-1) is used to describe every incident (or emergency call) to which your fire department responds. The Basic Module 

should be filled out for every incident to which the department responds. A sample 

of the Basic form is shown in Figure 3-2 on page 30.

The Fire Module (NFIRS-2) is used to describe each fire incident to which 

your fire department responds and must be used in conjunction with the 

Basic Module (NFIRS-1). For wildland fire incidents, the Wildland Fire 

Module (NFIRS-8) can be used instead of the Fire Module if that option 

is selected for use by your state or local reporting system administrator. 

A sample of the Fire form is shown in Figure 3-4 on page 32.

The Structure Fire Module (NFIRS-3) is used to describe each structure fire

to which your fire department responds. This module must be used 

in conjunction with the Basic Module (NFIRS-1) and the Fire Module 

(NFIRS-2). When reporting using the paper forms, NFIRS-3 is generally 

printed on the back of the NFIRS-2 Fire form. A sample of the Structure 

Fire form is shown in Figure 3-5 on page 33.

The Civilian Fire Casualty Module (NFIRS-4) is used to report injuries or 

deaths to civilians or other emergency personnel (such as police officers or non-fire department EMS personnel) that occur in conjunction 

with a fire incident. The Civilian Fire Casualty Module must be used in 

conjunction with the Basic Module, the Fire Module, and if applicable 

the Structure Fire Module. NFIRS-4 is specifically designed for reporting 

injuries and fatalities caused by, or related to, a fire. To report non-fire 

related injuries to civilians the EMS Module (NFIRS-6) can be used. A 

sample of the Civilian Fire Casualty form is shown in Figure 3-6 on page 34. 

The Fire Service Casualty Module (NFIRS-5) is used to report injuries or 

the deaths to firefighters. The module can also be used to report the exposure of a fire fighter to chemicals or biological agents at an incident 

where that exposure does not result in any symptoms at that time but 

where that exposure or accumulated exposures could lead to an illness 

at a later date. This module must be used in conjunction with the Basic 

Module and may be used with any of the other modules. A sample of the 

Fire Service Casualty form is shown in Figure 3-7 on page 35, and Figure 

3-8 on page 36.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

TECHNICAL DOCUMENTATION

28

The EMS Module (NFIRS-6) is an optional module that can be used by 

those fire departments that provide emergency medical services to their 

community. It should be used only when the EMS Module option is 

selected by your state or local reporting system administrator. The module is used to report all medical incidents where the fire department 

provided the primary patient care. This includes incidents where there 

were civilian fire-related injuries and a Civilian Fire Casualty Module was 

completed, and where there were fire fighter injuries and a Fire Service 

Casualty Module was completed. Note – This is not a patient care record, 

but should be used in conjunction with the local requirements for patient care. This module can be used in conjunction with the Basic Module (NFIRS-1). A sample of the EMS form is shown in Figure 3-9 on 

page 37.

The Hazardous Materials Module (NFIRS-7) is an optional module used to 

report major spills or releases involving hazardous materials. It should 

be used only when the Hazardous Materials Module option is selected 

by your state or local reporting system administrator. This module is designed to be used in conjunction with the Basic Module (NFIRS-1) and, 

if appropriate, the Fire Module (NFIRS-2) or other modules to provide 

detailed information about incidents involving hazardous materials. A 

sample of the Hazardous Materials form is shown in Figure 3-10 on page 38.

The Wildland Fire Module (NFIRS-8) is an optional module used to report incidents that involve wildland or vegetation fires. It should be used 

only when the Wildland Fire Module option is selected by your state or 

local reporting system administrator. This module must be used in conjunction with the Basic Module (NFIRS-1) and replaces the Fire Module (NFIRS-2) for wildland fire incidents. A sample of the Wildland Fire 

form is shown in Figure 3-11 on page 39.

The Apparatus Module (NFIRS-9) and Personnel Module (NFIRS-10) are optional department use modules used to report detailed information on the 

apparatus and personnel that respond to the incident. They should be 

used only when the Apparatus or the Personnel Module option is selected by your state or local reporting system administrator. The Apparatus 

Module (NFIRS-9) is used to report data specific to each piece of apparatus that responds to the incident. It includes data that can be used to 

calculate response time and time out of service. The Personnel Module 

(NFIRS-10) is used to report the same data on a piece of apparatus but 

also provides for tracking the personnel associated with that apparatus. 

These optional modules can be used in conjunction with the Basic Module (NFIRS-1) for any type of incident. A sample of the Apparatus form

TECHNICAL DOCUMENTATION - INCIDENT MODULE RULES

Incident Module Rules

TABLE 3-3. NFIRS 5.0 Incident Module Rules

REFERENCE # RULE

1 The Basic Module is always required for Incident Types: 100-911

2 If Incident Type = 571 (stand by) and if Aid Given or Received = codes 3, 4 , then only the information on 

the Basic module through Block D (Aid Given or Received) need be completed by the department giving aid. 

The rest of the Basic Module and the other modules as applicable are optional.

3 If Incident Type = any other Incident Type than 571 and if Aid Given or Received = codes 3 or 4, and the 

“THEIR FDID” information in Block D is entered, then only the information on the Basic module through 

block G1 (Resources) and the Fire Fighter Casualty Module (when there is a casualty which, including additionally Block H1 on Basic) must be completed by the department giving aid. The remainder of the Basic module and any other modules associated with the incident may be optionally completed but are not 

required. The information not captured by the department giving aid will be captured by the department that 

receives aid for that incident.

4 Aid Giving Departments and Aid Receiving Departments always track their own Fire Service casualties separately. If a Fire Service Casualty occurs in a department giving aid, they should also complete the H1 Casualties 

block on the Basic Module in addition to the FS Casualty Module.

5 The department receiving aid is responsible for tracking and entering all of the civilian casualty information 

for the incident.

6 If aid is given (codes 3, 4), then only the information on the Basic module through block G1 (Resources) 

must be completed by the department giving aid unless a fire service casualty also occurs, then the giving 

department must also complete the Fire Service Casualty Module. The remainder of the Basic module and any 

other modules associated with the incident may be optionally completed but are not required. The information not captured by the department giving aid is captured by the department that receives aid for that 

incident.

7 The Fire Module is always required for the following Incident Types (with the exception of aid given incidents): 100, 110-112, 120-138, 161-164 (160 is not included here because that code can be a wildland fire)

8 The Fire Module for is never (ever) allowed for: 200-911

9 The Fire Module is optional for the following Incident Types: 113-118, 150-155

10 If the Wildland Module is not used in place of the Fire Module, then the Fire Module must be completed for 

Incident Types: 140-143, 160, 170-173

11 The Structure Fire Module is always required for Incident Types: 111-112 (Only the Structure Type element is 

required on the Structure Module for code 112, the rest of the module is optional) 120-123

12 The Structure fire Module is never allowed for Incident Types: 130-173

13 The Structure fire Module is optional for Incident Types: 113-118

14 If the Fire Module is not used in place of the Wildland Module, then the Wildland Fire Module must be completed for Incident Types: 140-143, 160, 170-173

15 The Wildland Module is optional for Incident Types: 561, 631, 632

16 The Wildland Module is never allowed for Incident Types: 100-138, 150-155, 161-164, 200-555, 571-621, 

641-911

17 If used, the Arson Module is only allowed for Incident Types: 100-173 (Fire Cause field code on the Fire Module must also be ‘1 Intentional or ‘2 Unintentional’ or ‘5 Cause under investigation’ or ‘U Undetermined after 

investigation’. If the Wildland Module is used instead, the Wildland Fire Cause must be ‘7 Intentional’.)

18 If used, the EMS module is only allowed for Incident Types: 100-243, 311, 320-323, 351-381, 400-431, 

451, 900

TECHNICAL DOCUMENTATION - SYSTEM FIELD SECURITY LEVELS

System Field Security Levels

The following table lists the default security level for each field in the NFIRS 5.0 system. The security level 

is the highest level at which the data in the field may be released from the national system. Please note that 

these are the default settings and may be configured differently at the option of individual states or fire departments. The purpose of these settings is to prevent data from being released publicly at the federal level 

when to do so would conflict with state or local jurisdiction privacy laws.

Sensitive data (marked as anything other than “Federal” in the table below) transmitted by vendor software 

and collected by the USFA NFIRS 5.0 software will be handled in the following manner once it is in the that 

system:

Data fields that are marked “Fire Department” in the table are collected and stored in the state database but 

may not be released publicly without permission of the originating fire department.

Data fields that are marked “State” in the table are collected and stored in the Federal Database but may not 

be released publicly without permission of the originating state.

These data security rules are in effect once the data passes into the USFA software system via transaction file.

Incident Flat File Transfer Format

Overview

This section explains some of the conventions used in documenting the 

NFIRS 5.0 Incident Transaction File Format.

Transaction Record Hierarchy

The incident transaction records have been designed under the assumption that if a particular piece of information has not been collected as 

part of an incident, an empty record should not be transmitted. To accomplish this, a transaction hierarchy has been created so a parent transaction can be sent with only those applicable child transactions.

Example:

If aid was not given or received during an incident, the Aid Given or 

Received Transaction (1020) doesn’t need to be transmitted.

However, it must be mentioned, that if a transaction record is empty at 

the time of transmittal, but child transactions to that record are not, an 

empty parent transaction is required.

Example:

If the Mobile Property section of the Fire Form has been filled out, 

but the remainder of the Fire Form has not been entered, an empty 

Fire Form Transaction (1100) would need to be sent along with the 

Fire Mobile Property Transaction (1120). Note: The Fire Equipment 

Involved Transaction (1130) and File Attached Transaction (1110) 

would not need to be included, since they are child transactions and 

are empty.

All child transactions need to be included in the transaction file, after 

their corresponding parent transaction (although how many records after the parent transaction is irrelevant, as long as it is prior to the next 

incident).

Table 3-5, “Transaction Hierarchy Table,” on page 132 depicts the Incident Transaction Hierarchy and the associated Parent/Child relationships.

Delimiters

Fields within the transaction record can be delimited using a character or 

series of characters defined by the creator of the transaction file. The first 

record in the file MUST be the delimiter. NOTE: The delimiter MUST be 

different from the sub-delimiter used to denote multiple choice answers, 

which is a semi-colon (;) (explained in detail below).

Transaction Record Termination

All records in the file must be terminated with a delimiter, followed by a 

carriage return, followed immediately by a line feed.

Vendor Identification and Software Identification

Each vendor and/or custom system will be assigned an alphanumeric 

Vendor Identifier after they have been registered at www.nfirs.fema.gov 

as a NFIRS 5.0 software vendor. The Vendor Identifier assigned may be 

up to 10 characters in length. In addition, each version of the software 

activated will be assigned a unique alphanumeric Software Identifier. The 

Software Identifier may be up to 5 characters in length.

When entered in NFIRS 5.0 transaction files, all alpha characters in the 

Vendor Identifier and the Software identifier fields must be upper case. 

The second record in the file MUST contain both the vendor and software identification numbers.

Example:

Delimiter ^

Vendor XYZ Vendor Identification Number 12S22R69K

Software Version 1.1 Software Identification Number 1234C

Vendor and Software Identification Record 12S22R69K^1234C^

Addition, Deletion, Change and No Activity Transaction Flags

Each paper based form for the NFIRS support a Delete/Change flag in 

section A. This convention has been mimicked in the transaction file format.

Each Transaction Record has a Transaction Type field, which can have 

the following values.

Value Transaction Type

Blank Addition

1 Change

2 Delete

3 No Activity

Add Incident

When a new incident is transmitted, the first record should be the 

Basic Incident Transaction. If this is not the first record of the new 
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 135

TECHNICAL DOCUMENTATION - INCIDENT FLAT FILE TRANSFER FORMAT

incident, a fatal error will be generated. All subsequent transactions 

are included with the incident until the key values change or the end 

of the file is reached. 

Change and Delete Transaction

When an incident needs to be modified, a Change transaction should 

be transmitted. This includes changing records that already exists as 

well as transmitting new records for an existing incident (e.g. adding 

another casualty record to an existing incident). This change transaction must contain all the field values that should replace all the existing values for that transaction. (i.e. – If one field in a transaction 

changes, the entire transaction must be transmitted).

When a particular transaction has been removed from an incident, a Delete transaction should be transmitted. When a parent transaction is deleted, all child transactions for that parent are also deleted. If the Basic 

Incident Transaction is deleted, the entire incident is deleted. (Including 

any exposure record for fire incidents)

All transactions for an incident must appear at the same point in the 

transaction file. To ensure proper execution of change and delete 

transactions for an incident, they must be grouped into the following 

order.

•	 Deletion of existing records for the incident (in descending 

sequence)

•	 Addition of new records for the incident (in ascending sequence)

•	 Changes to existing records for the incident

Delete transactions MUST be grouped in descending sequence to ensure proper processing. For example, if three (3) casualty records 

exist for an incident and the last two (2) are to be deleted, the transactions should be transmitted as follows:

•	 Delete Casualty Number 3

•	 Delete Casualty Number 2

Addition transactions must be aware of any/all delete transactions 

that have been previously processed for the incident, and must use 

the appropriate sequence numbers. If in the above example, a new 

casualty were to be added after the delete transactions had been processed, the first casualty added must use Casualty number 2.

No Activity

No Activity transactions should only send the 1000 Incident Header 

Transaction. A code of “3” for No Activity should be entered in the 

Transaction Type (the 7th element) for these transactions.

Fire Department Transactions

The Fire Department Transactions records (record types 2000 through 

2020) are provided for the transmission of specific fire department information. These records, when transmitted, need to be contained in 

a separate flat file (i.e. These records can not be transmitted as part of 

the incident flat file). When reporting begins under NFIRS 5.0, each department will need to submit an initial Fire Department Header Record 

(record type 2000) in a separate flat file so that basic information about 

each department can be established in the State database.

Sequence Numbering Methodologies

When multiple records can occur for a single type of transaction, the 

transactions employ one of two possible numbering methodologies. For 

both types of methodologies, the numbers must be incremented by one 

(1). In addition, the transaction records must occur in the file in their 

ascending sequential order (although the transaction records do not necessarily need to appear one after the other). 

Zero Based

Numbers starting at 0 and incrementing by 1.

One Based

Numbers starting at 1 and incrementing by 1.

Data Types Legend

A (Alphabetic)

Alphabetic characters. If the user has not provided information, 

an empty field should be transmitted.

X (Text)

Alphanumeric or special characters. If the user has not provided 

information, an empty field should be transmitted. 

N (Numeric)

Integer numbers (no decimal points). If the user has not provided information, an empty field should be transmitted. All Integer values are assumed to be positive. Any fields which allow 

a negative Integer value have been denoted with “+ or –” in the 

comment field. Negative numbers should be transmitted with 

the minus sign preceding the digits. 

F (Floating Point)

Floating point precision numbers (The expected length column 

depicts the max left and right side precision). If the user has not 

provided information, an empty field should be transmitted.

C (Coded Field)

The coded field relating to an entry in the code table. Most coded 

fields allow for Plus+ One codes. For these fields the expected length of the coded entry is depicted as (National length OR 
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 137

TECHNICAL DOCUMENTATION - INCIDENT FLAT FILE TRANSFER FORMAT

Plus+ One length). Only fields with this notation in the expected 

length column allow for Plus+ One definitions. If the user has 

not provided information, an empty field should be transmitted. 

Y (Yes/No)

A (Y)es/(N)o flag. NOTE: This is case sensitive and must be capital Y or N. If the user has not provided information, a value of N 

should be transmitted (if no value is transmitted, N is assumed).

Positive and Negative Numbers

Certain Numerical Fields can contain positive or negative numbers. 

When a numerical field has a value that is positive, only the number 

should be given and the field length requirements should be observed. 

However, when a field value is negative, the number should be preceded 

by a minus sign (-), and the field length requirements should be observed, without accounting for the minus sign. 

Multiple Choice Fields

Fields that permit multiple values (e.g. a multiple choice coded field) 

must use a semi-colon (;) to separate the coded values. The field must 

ALWAYS end with a semi-colon, EXCEPT if the field contains no values.

Example:

Delimiter: ^

User had selected the following coded values (1,22,30).

(Prior fields) ^1;22;30;^ (Subsequent fields)

Note: If the field had been empty, the transaction record would appear as follows:

(Prior fields) ^^ (Subsequent fields)

Multiple Choice fields allow for Plus+ One codes (described above). A 

‘MC’ in the Comments column designates multiple Choice fields. In addition, the maximum number of responses allowed is noted in parenthesis. 

If ‘None’ is the given response for a multiple choice questions, the ‘None’ 

code should be listed in the field. This allows for the critical differentiation between a ‘None’ response and a field which had no response. 

Date and Time

Date and Time field responses can have the following notations in the 

transaction, depending on the type of field (Date Only or Date and Time).

Field Type Scenario Field Format

Date Only or 

Date and Time

No Date or Time Provided Blank

Date Only YYYYMMDD

Zip Code

Zip Codes can be provided using either 5 or 9-digit notation. NOTE: No hyphens should be used when 

transmitting the 9-digit notation.

Zip Code Type Field Format

5-digit Notation NNNNN

9-digit notation NNNNNNNNN

User Defined Transactions

User may define their own NFIRS 5.0 transaction types in order to collect data fields not specified in the 

national NFIRS 5.0 standard. These fields may be defined by states or by local fire departments for their own 

use locally. The 7000 transaction series is reserved for local fire department use. The 8000 series is reserved 

for state use. The 9000 series is currently reserved for future national expansion. 

In order to properly set up a user defined transaction, use these guidelines: 

1. Each user defined transaction must contain the first seven key fields in the Incident Header (1000) 

transaction before beginning the user defined fields. 

2. The user defined transactions must follow the same format and rules defined in this document for standard NFIRS 5.0 transactions.

DATA DICTIONARY

Data Dictionary

The NFIRS 5.0 data dictionary codes that follow contain a shorter version 

of the code descriptors for the NFIRS 5.0 specification. These descriptors 

are a maximum of fifty (50) characters in length and are intended for 

use in automated NFIRS 5.0 data collection systems. The full length code 

descriptors are available in the NFIRS 5.0 Reference Guide available from 

the United States Fire Administration.

Important Notes For Developers:

Certain codes in the data dictionary are designated as conversion only 

codes in the following manner:

Code # Code Descriptor (conversion only)

Codes that are identified in this manner are used solely to store data converted from the NFIRS 4.1 format and are never used for the collection 

of data in NFIRS 5.0. Under no circumstances should these codes ever be 

included in automated data entry systems’ code look-ups, pick-lists or 

code tables. Including the “conversion only” codes in such a manner will 

result in a failure to successfully complete NFIRS 5.0 software certification. Also note that in some cases the (conversion only) designation at 

the end of codes may make the total descriptor length exceed 50 characters. Since these codes are not to be used to collect data, this should not 

have an impact on the descriptor field size.

Please note that for the numeric code values listed in the following pages, hierarchical code placeholders are used. These placeholders are not 

themselves valid codes used for data entry. Instead they are used as section titles for code groups and are intended for use in automated picklists and database groupings used by data analysts. They should never be 

allowed as valid choices for data entry and will be rejected as invalid by 

the NFIRS 5.0 edits. Some examples of code placeholders are “1 Fire” 

and “10 Fire, other” in the Incident Type field listing below.

Tables for all of the data dictionaries can be obtained on the USFA website at: http://www.nfirs.fema.gov/documentation/design/

DATA DICTIONARY - HAZARDOUS MATERIALS MODULE

HazMat Chemical Database

The HazMat Chemical Database is provided to developers as a means of 

maintaining consistency with the NFIRS 5.0 standard software and also 

in order to improve consistency and usability of chemical name information collected in the NFIRS 5.0 HazMat module.

The HazMat Chemical Database consists of many, but not all, of the most 

commonly released chemicals currently responded to by the nation’s 

fire service. The HazMat Chemical Database was created as a product of 

the development of the Hazardous Materials Guide for First Responders 

which, in turn, was developed under the Firefighters’ Safety Study Act 

(Pub. L. 101-446 - Oct. 22, 1990). The database is intended to be a living 

document and will be updated on a regular basis as warranted.

Intended Use By Developers

The Chemical Database contains a Chemical ID Number, which should 

be used as an internal key uniquely identifying chemicals and their associated trade names. The Chemical ID Number key is designed for internal 

use by software only and is organized in the following manner:

3. Digits 1 through 4 are the unique identifier for a chemical (ex. Acetal 

is 0001).

4. Digits 5 through 7 are a unique identifier for synonyms or trade 

names for that chemical.

5. Zeros (000), in the Trade Name Identifier (positions 5 though 7) indicate a base chemical name (not a trade name).

6. If the Trade Name Identifier is greater than zeros (001-999), the record is a trade name alias for the base chemical. 

7. Base chemicals and their associated trade names share a common 

unique identifier (positions 1-4).

Example: 

Acetal has a Chemical ID Number of 0001000. The numbers 0001 in 

positions 1-4 uniquely identify the chemical as Acetal. The last three digits are zeros so Acetal is the base chemical name. Acetal also has several synonyms. Is it also known as Acetaldehyde ethylacetal, which has a 

Chemical ID number of 0001001. The first four positions (0001) are the 

same (indicating it is still Acetal) but the 001 in the last 3 positions indicates that it is the first trade name for Acetal. Acetal has three trade names 

(001-003) associated with it in the HazMat Chemical Database. They are 

all the same chemical as the base chemical name Acetal (0001).

Data Entry Guidelines

Chemicals selected from the database by the user must be taken from the 

HazMat Chemical database table and stored in the Chemical Name field. 

If a chemical trade name is selected (positions 5-7 greater than zeros) 
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

DATA DICTIONARY - HAZARDOUS MATERIALS MODULE

204

the base chemical name (000 record) should be stored in the field. The 

associated UN Number and CAS number may also be automatically filled 

from the database when there is a match and those values are present in 

the record. If the chemical involved is not present in the Chemical Database, the user must be allowed to directly enter the name of the chemical, the UN Number and the CAS Number into the appropriate fields.

This method outlined above allows for uniform spelling and formatting 

of data when values are present in the database but does not preclude 

entry of chemical names if they are not present in the database. Using 

the example above, if there was yet another trade name for Acetal that 

was not included in the HazMat Chemical Database, the user should 

be allowed to enter that trade name into the Chemical Name field even 

though it was not present in the database.

The most current version of the Chemical Database may be obtained from

TECHNICAL DOCUMENTATION - CONVERSION TABLES

Conversion Tables for NFIRS 4.1 to 5.0

This section is provided to assist in the transition from NFIRS 4.1 to 

NFIRS 5.0. Users of data that has been converted are cautioned to review 

both the old data description and the new data description(s) as there 

may be some slight variations and some assumptions had to be made.

NFIRS databases from data years 1999 through 2008 contain converted 

NFIRS incidents using the tables in this section as a basis. On January 

1, 2009, NFIRS ceased collection of NFIRS legacy version 4.1 incidents. 

Data in the 4.1 format collected after the NFIRS 4.1 sunset date are no 

longer converted and imported into the NFIRS database. 

General guidelines

All insufficient information “0” have been changed to the appropriate 

“other” classification.

Any reference to classifications in another data element are to the NFIRS 

4.1 classifications if in the NFIRS 4.1 column and to the NFIRS 5.0 if in 

the 5.0 column

Abbreviations used in conversion tables are as follows:

MPT = Mobile Property Type.

FPU = Fixed Property Use.

AFO = Area of Origin.

EII = Equipment Involved in Ignition.

TMI = Type of Material Ignited.

SS = Structure Status.

NFIRS 4.1 Carryover Elements

Note that the following elements will be carried in the NFIRS 5.0 system 

as part of the converted 4.1 records. These elements are not collected in 

NFIRS 5.0 and are carried in the converted 4.1 records for legacy purposes only:

Method of Alarm from Public.

Method of Extinguishment.

Construction Type.

Extent of Smoke Damage.

Type of Material Generating Most Smoke.

Form of Material Generating Most Smoke.

SYSTEM IMPLEMENTATION GUIDELINES

336

TABLE 4-2. Hardware and Software Platform Guidelines - System Type: Small LAN

Hardware Workstations on the LAN should be a 486 based PCs and above is the recommended platform. 

32MB of RAM is recommended as a minimum for Windows 95 and 64MB for Windows NT.

Servers should be Pentium class machines with a minimum of 64MB of RAM. If possible SCSI hard 

drives should be used in the server. 

These recommendations are based on the current technology and industry standards.

Operating Systems/ 

Network OS

•	 Windows 95

•	 Windows NT

•	 OS/2

•	 Mac

Development Tools For small LANs with no remote access requirements PC development tools that produce Windows 

based applications that utilize PC-based file systems. Examples of such tools include but are not 

limited to:

•	 FoxPro 

•	 Visual FoxPro

•	 Paradox 

•	 dBase 

•	 Visual dBase

•	 Clipper

•	 Visual BASIC

For larger single sites, LANs including those that require some remote access PC tools to develop 

Windows-based applications that can utilize RDBMS engines may be more appropriate. This will 

depend on the individual needs of the purchaser with regard to volume of data, number of remote 

users, and required response times. Examples of such tools include, but are not limited to:

•	 Visual FoxPro

•	 Visual dBASE

•	 Visual BASIC

•	 Power Builder

•	 SQL Windows

File System For small LANs with no remote access requirements PC file systems that support relational or hierarchical data base structures. Examples of these file systems include, but are not limited to:

•	 xBase files

•	 Access files

•	 Btrieve files

For larger single site LANs, LANs that require some remote access, or sites that will be capturing 

and processing very large amounts of data, a RDBMS is a better choice. Examples of these file systems include but are not limited to:

•	 SyBase

•	 SQL Server

•	 DB2/2

Record Volume/Number 

of Users

Small LAN installations that are running applications that rely on xBase file structures must be 

aware that data bases with large amounts of data can greatly affect application performance. This 

degradation of performance can be particularly noticeable on remote access work stations. This is 

due to the inherent nature of the way these types of files are processed by the applications that use 

them. In order to perform certain tasks, the entire database must sometimes be transported over 

the LAN wire or, in a worst case scenario, over a slow telephone line. Depending on what level of 

performance you require, this type of installation can be expected to handle from several thousand 

to 10 or 20 thousand records. A small LAN running an application that is using RDBMS can handle 

very large amounts of data and still maintain an acceptable level of performance. However, for 

applications that will only be dealing with small amounts of data, this data access method will be 

slower than a simple flat file data base.

TECHNICAL DOCUMENTATION - SOFTWARE CERTIFICATION PROCEDURES

NFIRS 5.0 Vendor Software 

Development Procedures

The United States Fire Administration (USFA) will no longer certify vendor 

transaction files for the NFIRS 5.0. The USFA will instead maintain a list of fire 

software vendors that have registered with USFA to obtain NFIRS 5.0 development materials and the vendor validation tool. We will also maintain vendors’ 

readiness status’ on the list based on their reports to us on their status.

 The new procedure has 5 steps:

1. Vendors will register their company/organization and their software to 

receive a vendor ID and a software ID. This step is the same as in the previous certification procedure. All transaction files processed at the national 

level are required to have these two IDs embedded in the transaction file as 

specified in the design documentation. News, Design Documentation, and 

Tools for Vendors may be found at the vendor section of the USFA website. 

https://www.nfirs.fema.gov/vendors/

2. Vendors will be requested to develop software using the NFIRS 5.0 design 

documentation and then test their output transaction files using the validation tools USFA provides for those purposes. NFIRS design documentation 

and other information may be downloaded from the registration website at: 

http://www.nfirs.fema.gov/documentation/design/

3. Vendors are requested to notify USFA when their product development is 

completed and tested to be compatible with the national NFIRS 5.0 database standard.

4. Vendors who have notified USFA in step 3 above will be marked as “active” 

vendors on the registered list. This new status will supersede the previous 

two status categories of “conditionally certified” and “fully certified”. 

5. Fire Departments and states may use the USFA maintained list of vendors 

as a resource when shopping for a software product.

Because the USFA will no longer nationally certify vendor’s NFIRS 5.0 transaction files formats, it will be extremely important for state agencies, fire departments and vendors to continue monitoring data quality issues.

State agencies are the authority for state reporting compliance. Issues with 

NFIRS vendor files should be addressed by the fire department, the vendor 

and the state involved. The USFA will continue to act as a resource for states to 

identify data problems at the national level.

Vendors should retest their software after software revisions or version changes.

In order to maintain a uniform National reporting standard:

Fire departments should make sure they have the most current version of the 

vendor software installed.

States and fire departments need to ensure that their vendor’s data files remain 

compatible with the national system.

Query and Reporting Requirements

Reporting Requirements

All database inputs to the standard reports defined below will have definable database filters which can be set by the report user prior to report generation. The filter will consist of predefined field parameters that 

will allow generation of data subsets based on the values entered before 

report generation. Field parameters will consist of a range of values or 

values greater, less than or equal to a designated value. Those parameters 

that require ranges of values are designated by “(range of)” after the 

parameter field name. Text field parameters require the ability to do partial searches and the use of wildcard characters. More complex queries 

involving the use of the Boolean logical “or” statement or combinations 

of Boolean “and/or” logic will require use of ad hoc query capabilities 

described at the end of these reporting requirements. Note that not all 

field parameters may be available for each report depending on the report type. The following is a total list of all NFIRS 5.0 field parameters

Cause Categories Report

The USFA fire cause methodology consists of using a set of hierarchical 

sorting rules based primarily on the Ignition Cause and Factors, Equipment Involved in Ignition, and Heat Source (plus Exposure Number) to 

create a hierarchical sorting of all fires into 35 priority (hierarchical) 

cause codes. These priority cause codes are then regrouped into 12 major cause categories plus a residual unknown-cause group. This framework has proved enormously useful to analysts over the years and is continued under NFIRS version 5.0. 

Fires are assigned to a cause category based on a set of rules. Fires that 

do not meet the criteria are then available for cause assignment from the 

next rule. Anything left at the end is declared “Unknown”. These hierarchical groups are then grouped together to form the 13 major cause 

groups that fire analysts currently use.

The Cause Category Methodology Matrix table containing the new hierarchical grouping rules is available by clicking the following url:

http://www.nfirs.fema.gov/documentation/design/

Note: As was the cause in previous versions, these cause category groupings are intended for use with structure fires only. They will not accurately portray causes for Outside or Vehicle fires and they were not designed 

for that purpose.

SYSTEM IMPLEMENTATION 

GUIDELINES 

System Selection Issues

Implementation of NFIRS 5.0 includes decisions about hardware, software, policy development, training, and planning. NFIRS 5.0 users have 

several options to consider when choosing their hardware architecture, 

software application and database for implementation. Decisions regarding these issues are made with consideration for the current demand for 

information collection and management, anticipated expansion in the 

number of users, and the expectations for data analysis.

NFIRS Version 5.0 is designed to make extensive use of the technology 

that is available today, while allowing for future new technologies. NFIRS 

5.0 takes advantage of the Internet for transmitting local fire department 

data to both the state and national database.

The USFA will make standard NFIRS 5.0 software available to states upon 

request. This software is designed to provide data entry, validation, data 

conversion, data and system management services. It is designed to run 

on most 32-bit operating systems. It can interface with other databases 

through the Open Database Connectivity Standard (ODBC) at the local or 

state level. States that choose to distribute the Data Entry software to their 

departments must agree to provide all technical and help-desk support to 

departments within their jurisdiction.

Platform Architecture Overview

Stand Alone Personal Computers (PC)

Personal computers can be a cost effective approach to incident data 

collection and analysis. A stand alone PC is appropriate for situations in 

which there are a limited number of users who need to access the application, and concurrent access is not an issue. A fire department with a 

single station and a few qualified data users may be able to successfully 

use a stand-alone application. A PC application may be sufficient even 

if a large amount of data must be captured, provided the data need not 

be shared by users at other workstations. A department with several fire 

stations that sends all incident reports to a central location to be entered 

into the reporting application may also find that the stand alone application meets its needs.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

SYSTEM IMPLEMENTATION GUIDELINES

334

The advantages of using a PC can include:

•	 Generally the least costly alternative in terms of initial cost and ongoing maintenance

•	 Can usually run on a moderately configured PC. Windows 95-based 

applications generally will require a pentium machine with 32 MB 

of RAM. Windows NT-based applications generally will require a 

Pentium or above machine with 64 MB of RAM.

•	 Administration and maintenance of the application is controlled at a 

single point and can be handled by a single person.

•	 A large amount of data can be collected and reported provided the 

PC hardware has the capacity to store and process the data.

However, the application and data can only be accessed from a single 

location by one person at a time. It may be difficult or impossible to add 

Local Area Network (LAN) access to the application at a later date and 

still maintain acceptable performance of the system.

Record Volume/Number of Users Stand alone applications utilizing one of the listed file structures are capable of managing large numbers of records provided the PC running the application is equipped 

with adequate RAM and hard disk space. A well designed application should be able to 

handle record numbers in the 10,000 to 20,000 range on a stand alone PC.

SYSTEM IMPLEMENTATION GUIDELINES

Local Area Network

Local Area Networks (LAN) expand the capability to include multiple users 

working concurrently in the system. An incident reporting application that is 

designed to run on a LAN is appropriate for situations in which there are a 

number of users who need concurrent access to the application. A LAN-based 

application running in a fire department that needs several people at the 

same location to use the application at the same time will provide connectivity and shared access. Depending on the amount of data being captured and 

the design of application software, a LAN also may be able to supply limited 

access to workstations outside the physical location of the network through 

remote access. A small LAN can be configured with one server providing account verification, file sharing, print sharing, and application sharing.

LAN advantages include:

•	 Access to the application and data concurrently by a set number of users.

•	 Controlled access to the application by the network administrator. 

Groups of individuals can be given access to just those applications for 

which they have a need.

•	 Controlled administration and maintenance of the application at a single 

point, with the results available to all workstations connected to the LAN.

•	 The ability to add workstations as more people need access to applications served by the network. It is also likely that additional software licenses will be required as users are added.

The LAN will require a higher commitment to system maintenance, both 

hardware and software, than a stand alone PC. A LAN, though, raises issues 

not encountered in PC platforms.

•	 The cost of hardware for a LAN can be considerably more than a stand 

alone PC. A dedicated server machine is needed as well as workstation 

PCs to access the server. Additional LAN hardware, such as network interface cards and cable, must also be purchased.

•	 A LAN will require someone to administer its functions: backups, software installation and upgrades, security validations, hardware and software problem determination, etc. This can be someone at the user’s site 

who has been trained in the network operating system (NOS) or a vendor who has been contracted to handle the administration.

•	 A LAN will require a hardware maintenance contract to cover component failures and routine service.

•	 A large increase in the number of users on the LAN, or in the number of 

applications being run, may require additional servers.

•	 Adding remote access to the LAN may result in unacceptable performance of certain applications at the remote workstations.

The Hardware and Software Platform Guideline Table on the next page describes additional issues to be considered when exploring a LAN system.

Hardware Workstations on the LAN should be a 486 based PCs and above is the recommended platform. 

32MB of RAM is recommended as a minimum for Windows 95 and 64MB for Windows NT.

Servers should be Pentium class machines with a minimum of 64MB of RAM. If possible SCSI hard 

drives should be used in the server. 

These recommendations are based on the current technology and industry standards.

•	 FoxPro 

•	 Visual FoxPro

•	 Paradox 

•	 dBase 

•	 Visual dBase

•	 Clipper

•	 Visual BASIC

For larger single sites, LANs including those that require some remote access PC tools to develop 

Windows-based applications that can utilize RDBMS engines may be more appropriate. This will 

depend on the individual needs of the purchaser with regard to volume of data, number of remote 

users, and required response times. Examples of such tools include, but are not limited to:

•	 Visual FoxPro

•	 Visual dBASE

•	 Visual BASIC

•	 Power Builder

•	 SQL Windows

File System For small LANs with no remote access requirements PC file systems that support relational or hierarchical data base structures. Examples of these file systems include, but are not limited to:

•	 xBase files

•	 Access files

•	 Btrieve files

For larger single site LANs, LANs that require some remote access, or sites that will be capturing 

and processing very large amounts of data, a RDBMS is a better choice. Examples of these file systems include but are not limited to:

•	 SyBase

•	 SQL Server

•	 DB2/2

Record Volume/Number 

of Users

Small LAN installations that are running applications that rely on xBase file structures must be 

aware that data bases with large amounts of data can greatly affect application performance. This 

degradation of performance can be particularly noticeable on remote access work stations. This is 

due to the inherent nature of the way these types of files are processed by the applications that use 

them. In order to perform certain tasks, the entire database must sometimes be transported over 

the LAN wire or, in a worst case scenario, over a slow telephone line. Depending on what level of 

performance you require, this type of installation can be expected to handle from several thousand 

to 10 or 20 thousand records. A small LAN running an application that is using RDBMS can handle 

very large amounts of data and still maintain an acceptable level of performance. However, for 

applications that will only be dealing with small amounts of data, this data access method will be 

slower than a simple flat file data base.

SYSTEM IMPLEMENTATION GUIDELINES

Wide Area Network

A Wide Area Network can be effective in large Metro departments and in 

regional settings in which many departments agree to share a system. A 

large jurisdiction, city, county, or state with a regional central reporting 

agency may need an incident reporting application that is designed to 

run on a large LAN or wide area network (WAN). This platform is appropriate for situations in which there are a large number, or geographically 

dispersed, group of users who need concurrent access to the application. 

The heavy volume of data and remote access requirements in this situation require an application that takes advantage of a relational database 

management system (RDBMS) running on a centralized server. It also is 

likely that additional servers are required to handle account verification 

and file sharing requirements.

The advantages users gain with a WAN include:

•	 Wide access to applications and other services provided by the network to a large and geographically dispersed group of users.

•	 A centralized data repository for collection and reporting purposes.

•	 Applications utilizing RDBMS technologies are generally more scalable. This allows for future growth of the system.

•	 Applications using RDBMS technologies are much more secure than 

applications using many other data management systems.

The Hardware and Software Platform Guideline Table on the next page 

describes additional information to be considered when exploring a 

WAN system.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

SYSTEM IMPLEMENTATION GUIDELINES

338

TABLE 4-3. Hardware and Software Platform Guidelines - System Type: Large LAN or WAN

Hardware Workstations on the LAN should be Pentium-based PCs as a minimum, although existing 486- 

based equipment may be used if performance is not an issue. 32MB of RAM is recommended for 

Windows 95, 64 MB of RAM is recommended for NT.

Servers performing account verification file sharing, and print-sharing services should be Pentium 

II class machines with a minimum of 64MB of RAM. If possible SCSI hard drives should be used in 

the server.

Application servers running the data base engine or other shared applications should be run from 

Pentium II class machines with 1 - 4 processors or RISC based machines. 

These recommendations are based on the current technology and industry standards.

Operating Systems/ 

Network OS

•	 Windows 95

•	 Windows NT

•	 OS/2

•	 MAC

The Network Operating Systems (NOS) includes Windows NT Server, Netware 3.x and 4.x, and 

OS/2 Warp Server. NOS on RISC machines should be UNIX or Windows NT.

Development Tools For larger LANs and WANs, PC tools that develop Windows-based applications to utilize RDBMS 

engines are more appropriate. Examples of such tools include but are not limited to:

•	 Visual Foxpro

•	 Visual dBASE

•	 Visual BASIC

•	 Power Builder

•	 SQL Windows

•	 Oracle Developer 2000

File System For larger LANs and WANs, a RDBMS is a better choice for a file management system. Examples of 

these files include but are not limited to:

•	 Oracle

•	 SyBase

•	 SQL Server

•	 DB2/2

Record Volume/Number 

of Users

Record volumes should be large enough, and remote access to data common enough, to make the 

investment in this type of technology worthwhile. Records numbering in the 10s to 100s of thousands are common in this type of system.

Above 20 users and with remote access to data required. More users can be added until performance of the system bogs down. At that time, increasing the power of the hardware can be done to 

restore the system to an acceptable level of performance.

Mainframe Computer

Mainframe systems can be cumbersome and complex, but can be appropriate where a municipal system is available. A mainframe-based solution is 

only possible if an existing hardware, software, and support structure already 

exists to support a mainframe environment. Even with such an environment, 

it is often difficult to obtain the programming and analysis support necessary to develop a large application. An organization with a mainframe environment will generally have an Information Systems Department that will 

work with the business area to determine the feasibility and economics of 

building a particular application on a mainframe. Anyone considering building an incident reporting application in this manner should consult with 

their internal data processing support organization.

Network Server Overview

File servers allow sharing of software applications through a central processing unit that downloads applications to workstations. Network servers can be 

divided into two broad categories: file servers that provide file sharing, print 

sharing, and authentication services, and application servers that run applications such as database engines or web servers. The two types of servers have 

different hardware and software requirements because they perform different types of services.

File Server

A file server runs a network operating system and supplies the application and 

data files to the network workstations. The applications execute and the data is 

processed on the workstation. The server needs fast, large hard drives and fast 

network adapters to provide optimum performance for the file and print sharing services provided by the server. The amount of RAM and processor speed 

are important to the user authentication and verification services provided by 

the server, but are usually not the limiting factor in file server performance.

An application that is being served from a file server loads the executable files 

into the RAM of the workstation. The workstation performs all of the work 

required by the application program. Data is transferred from the server to the 

workstation as it is needed to perform application functions. Applications that 

use flat file or xBase type databases can be slowed considerably by transmission times when databases become very large. In order to perform certain application functions, a copy of the entire database must be transferred from the 

server to the workstation for the application to process the data.

The network operating system that runs on the file server needs to have the 

ability to handle the sharing of disk and print resources among numerous 

connected workstations and to perform authentication and security functions. 

The NOS does not necessarily need to be a true pre-emptive multi-tasking operation system as the file server does not generally run any other applications.

The File Server Network Chart on the next page graphically displays a system 

that uses a file server.

SYSTEM IMPLEMENTATION GUIDELINES

Application Server

Application servers share the workload with the workstations, making 

the hard disk size and data transmission speed less critical than in a file 

server system. An application server runs a network operating system and 

runs shared applications such as a database engine. The application server shares the work to be done with the workstation. A database engine 

that is running on the server listens for requests from the workstations 

and processes those requests. Only the request is transmitted from the 

workstation to the server and only the answer is transmitted from the 

server back to the workstation. This arrangement puts an emphasis on 

the amount of RAM and number and speed of processors on the application server. Hard disk size and speed as well as transmission speed is also 

a factor affecting server performance, but these factors are not as critical 

for application server performance.

The network operating system that runs on the application server needs 

to have the ability to process multiple requests for data or other services, such as communication services, simultaneously. A true pre-emptive 

multi-tasking operation system is best for this type of server.

SYSTEM IMPLEMENTATION GUIDELINES

Software Selection Issues

Software decisions can be guided by key questions that address the efficacy of the program and vendor support. Software for a fire incident 

reporting system can be acquired from USFA (state-supported option 

only) or purchased as a standard package, much the same as word processing and desktop publishing programs. They can also be developed for 

specific custom application. Several points should be considered with either software approach. Many of the questions listed here could be used 

to develop a Request for Proposal to solicit bids for the installation and/

or to develop NFIRS 5.0 software in a jurisdiction.

Off-the-Shelf Products

These products are developed for distribution to multiple fire agencies. 

The purchaser buys the product in its current configuration with minimum customization.

•	 Is the software NFIRS certified?

•	 How many years has the vendor been in business?

•	 How much experience does the vendor have in fire service software?

•	 Does the vendor have any similar products?

•	 Can you obtain fully functional demonstrations of the program?

•	 Can the vendor provide a reference list of at least 10 customers?

•	 How will the vendor handle technical support and what is the cost?

•	 Can you review documentation and product tutorials?

•	 Is training available in the use of the software and how much does it cost?

•	 Is installation of the software available and how much does it cost?

•	 How does the vendor handle software fixes and what are the costs?

•	 How does the vendor handle maintenance releases and what are the costs?

•	 Is the software compatible with other applications, spreadsheets, 

word processing, third-party report generators, etc.?

•	 Will the vendor maintain this software with changes in operating 

systems?

•	 What are the system requirements?

•	 What are the system maximums, such as capacity for records (estimate your needs for 3 years)?

•	 Is the software compatible with your operating system?

•	 What data analysis is built-in?

•	 How does the vendor suggest handling data back-up and recovery?

•	 What is the vendor’s primary business?
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

Custom Application Development

Custom applications demand that the vendor focus on meeting the customers needs and standards. These products are developed and designed 

to meet the specific needs of a customer. The following questions are additions to those asked for standard software.

•	 Will access to the source code be available?

•	 What happens should the company or the product be sold?

•	 What development language will the vendor use?

•	 How does the vendor suggest handling platform maintenance?

USFA Supplied Software

The United States Fire Administration has developed client and server 

software for the use of states and departments. The software is designed 

to work with most 32-bit operating systems, such as Windows 95, Windows NT, System 7, UNIX, OS/2, etc. It incorporates platform portability 

through use of the JAVA software development language and can interface with non-ORACLE databases through an Open Database Connectivity interface. When standard system software components are used at the 

state or metro levels, a custom integration with existing databases may be 

required. For more detailed information about the USFA software option 

See “Standard USFA Software Implementation Guidelines” on page 353.

Quality Control Issues

On-scene reporting is the foundation on which a reliable system is built. 

Quality control is based on devising and using procedures that ensure 

precise and reliable data. Precision means complete and accurate data collection at the recommended level of detail for each coded field; reliability 

means the data is collected and coded consistently. NFIRS data flows from 

the local level to the state level and then to the national level through 

the transfer file specification. The local fire department is responsible for 

the quality of data in the transfer file it submits to the state. The state is 

responsible for the quality of the data in the transfer file it submits to the 

national level.

Quality control measures ensure consistency and reliability. Quality control issues focus on: 

•	 The software used to collect and analyze data

•	 The incident documentation process

•	 Editing the data and correcting errors

•	 Timeframes and deadlines for data submission throughout the system

•	 Accurate system participant information
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 345

SYSTEM IMPLEMENTATION GUIDELINES

Documenting the Incident

The data collected to describe an incident is the foundation of the system, therefore, the field participants in the system will need:

•	 Initial training for data collection

•	 Feedback on completeness and accuracy

•	 Refresher training on data collection and coding schemes

Those who investigate incidents must be able to determine cause and 

record the incident for later data entry. They need to do a complete job 

of assembling the facts of the incident and then consistently record them 

each time. Therefore, after the initial training of all fire departments for 

NFIRS 5.0, there should be a provision for annual refresher training.

There also should be a system in place to double check the collection 

and data entry work. Field edits and relational edits can be built into the 

system that will reveal unacceptable and unreasonable data. Data management personnel utilize these techniques to improve and validate the data.

Data Edits and Error Corrections

Editing and correcting errors is a system-wide activity, involving local, 

state, and federal organizations. All errors resulting from the edit/update 

process need to be reported to fire departments and the submission of 

corrections from fire departments needs to be encouraged. This is especially critical for fatal errors, which prevent the data from being entered 

into the NFIRS database.

The corrections for any errors reported to the local fire department by 

the state should be included in the next month’s submission of data 

to the state. Uniform coding at the national level also necessitates edit 

checks and quality control monitoring.

Timely Data Submission

Data submission deadlines are required, especially for the annual year-end 

cutoff to ensure final closure of the year. The state should establish and 

enforce a final data submission deadline for each year in order to close 

the processing. Without a final deadline, after which data is no longer accepted at the state level, data submissions will continue indefinitely. The 

state should encourage timely data submission from every fire department 

in order to submit the overall state’s data to the national level in time.

Meeting data submission deadlines support state and federal efforts to 

analyze and disseminate the data. A continuous steady effort promoting 

participation of all fire departments in a state is important for data quality. 

If the percentage of participating fire departments is highly variable, then 

problem trends are not as reliable. This is especially true when larger fire 

departments are involved in varying levels of participation from year to 

year.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

SYSTEM IMPLEMENTATION GUIDELINES

346

Statewide statistics for both fire and non-fire incidents are less accurate 

when a smaller percentage of fire departments are reporting and when a 

smaller percentage of incidents are reported. When the statewide problem statistics are lacking a significant percentage of fire incidents, the 

scope of the fire problem appears to be smaller than it actually is for that 

state. This results in less support of the fire service and less attention being paid to fire prevention efforts.

The information provided by a national reporting system loses value as 

it becomes less timely. The comparison of trends and the analysis of data 

queries from state to state and from metro department to metro department are not possible until the year is closed. The last state to submit its 

data to the national level determines when final national statistics and 

information will become available to all for that year.

Maintaining Fire Department Identification and 

Participation Information

Documentation of local participation helps states manage data submission and quality throughout the year. Two or more fire departments can 

merge into one, one fire department can split into more than one, new 

fire departments are formed, and existing fire departments cease to exist. Fire departments also change chiefs, phone numbers, addresses, and 

areas covered. It is important for the state to maintain accurate and up to 

date records on all fire departments.

It is also important to maintain logs of data received, data processed 

(edit/update), and errors found in data submissions by fire department 

for each month and year. It is important for a state’s credibility to be able 

to answer questions like, “Did you get the March data I sent 3 weeks 

ago?” These logs provide a handy reference to keep close watch on participation and timely reporting by fire department. Waiting until sometime after the final year-end deadline to realize that some fire departments have not submitted any data is too late.

Training Issues

Audience

There is a critical need for training at several levels of a primary fire 

reporting entity. This is critical to ensure accurate collection methods 

and strong support for the reporting system. Fire department personnel 

training can focus on cause determination and collection methods.

Fire Department Personnel

Those fire department members with reporting responsibilities, who 

work at the scene of the incident, are the important first link in the data 

collection process. Without their support and cooperation, the incident 

reporting system will break down at a most critical point. 
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 347

SYSTEM IMPLEMENTATION GUIDELINES

Training needs for these department members include:

•	 Cause Determination: Accurate reporting demands that the causes of 

fires and other incidents be found whenever possible. The quality of 

data can be significantly improved with an organized training program in cause determination.

•	 Data Definition: Primary data collectors need to first know what 

items are to become part of the system and understand how to define each item. This will require a working knowledge of the system 

data dictionary. At this point, great contributions can be made to data 

quality as the collection is made at the proper precision with consistent interpretation.

•	 Information Gathering: Primary collectors must know and use the 

proper mechanics to get the data into the system. This includes utilizing the appropriate forms and techniques to move the data from 

the scene of the incident to the point of computer input. It may even 

include computer input if these fire department personnel are responsible for it.

•	 Reporting Benefits: For the purpose of motivation, firefighters and 

other primary data collectors need to understand how the collection 

of data benefits them in their work. They need to feel that the data is 

being used to increase their effectiveness as firefighters.

Data Management Personnel

Data management personnel training concentrates on information collection and quality control. These are the personnel who are responsible 

for processing the data into its final form, usually in a computer disk 

file. They are responsible for the overall management of the data system 

and handle the dissemination of information developed from the data. 

In small departments, they may be the same firefighters who collect data 

at the incident scene. However, in larger departments they will likely be 

specialists whose primary task is to process incident reports.

•	 Data Collection System Mechanics: Training is needed in how and 

when to interface with the other members of the collection team. 

Scheduling of data submission and specific responsibilities of all 

those involved is important to those managing the system, including 

when and how to submit data to other agencies.

•	 Using the Computer Software: Most collection systems will be computer-based and the data managers will be operators of this equipment. They will need detailed training and instructions on how to 

utilize the software and hardware needed to process data for the incident system. In addition, training may be needed in operating systems and local area network systems.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

SYSTEM IMPLEMENTATION GUIDELINES

348

•	 Quality Control Considerations: Data managers have the major responsibility for maintaining high quality data. They need training in 

the many different techniques of ensuring that data is collected accurately and reliably.

Chiefs, Officers, and Data Users 

These are usually senior department personnel who turn the raw data 

into usable and understandable information for distribution. They will 

take the computer files and manipulate and refine the data into tables, 

graphics and other forms appropriate for the intended audience.

•	 Audience Recognition and Plausible Uses: Managers need training in 

recognizing the many different audiences for incident information. 

This information should include appropriate ways to present the information to a particular user.

•	 Data Analysis Skills: Appropriate training for these managers would 

include the many different ways to analyze the data and turn it into 

meaningful information. They should be qualified to utilize statistical 

programs as well as graphic presentation tools.

•	 Data Definitions: This group must be able to understanding the exact 

meaning of every data element and the codes that are used to classify 

the incidents. Thorough training on the data dictionary will enable 

these managers to properly interpret the information as they develop 

presentations for end users.

Training Frequency

Just as operations training is incorporated into a department’s routine, 

data collection and management need to become regular training events. 

Based on the needs of the department, training will be appropriate many 

different times. The size of the department, number of training personnel available, and the method of data collection all dictate the frequency 

of training events.

•	 Change-over Time: When a new reporting system is adopted there 

will be an urgent need to provide training for most of the department personnel. There will be many questions about procedures and 

features of the new system. This is an excellent time to provide those 

training classes while members are motivated to learn as much as 

they can about the new system. This training also will ensure that 

there is no drop in quality during the changeover.

•	 Regular Drills: Training drills afford an opportunity to provide reporting system training on a regular schedule. By giving an appropriate amount of training on a scheduled basis, personnel can learn 

the system without being pulled from their duties. This requires coordination from company officers.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 349

SYSTEM IMPLEMENTATION GUIDELINES

•	 Data Entry Point: Training materials should be present at the data entry points for regular use and reference by those personnel. The frequency of training would be as needed by those entering data.

•	 Scheduled Training Events: It will be helpful to schedule training 

events periodically to introduce new procedures and reinforce established ones. There will be times when the only way to accomplish 

the training goals is to put groups together and present classes.

Training Approaches

A wide variety of training approaches encourages individual and group 

exploration of the data system and its impact on the department.

•	 Organized Classes: In these situations, an instructor is placed in a 

class of an appropriate size and a traditional training event occurs. 

Many innovative techniques may be used such as audio/visual and 

computerized procedures, but the training is held in the traditional 

class format.

•	 Video Presentations: This approach utilizes a videotaped program as 

the primary medium for training. It can be a class presentation that 

has been reduced to video, or it can be actual or simulated action 

situations used for illustration and training. It may be accompanied 

by written tests or response documents.

•	 Computer-aided Instruction: These training events are usually done 

on an individual basis and utilize a computer to present the information and perhaps receive responses from the learners. Major types of 

computer aided instruction include tutorials, interactive programs, 

and game simulations.

•	 Help Files: These informational documents usually accompany computer programs. They can now be produced as stand-alone documents for use in different learning situations. They can be displayed 

using standard computer programs.

•	 Working Manuals: These documents are developed and provided for 

the purpose of step-by-step guidance in accomplishing the subject 

matter. They take the form of instruction manuals, documentation 

manuals, and handbooks.

•	 On-line Sources: It is now possible to distribute training information and instructions over local area networks and the Internet. This 

makes it possible to reach large audiences with a common body of 

knowledge of interest to many users.

Implementation Action Plan

Integrating hardware, software, policy development, and training requires an action plan that will help manage NFIRS 5.0 implementation. 

An action plan is a powerful tool to assist in clarifying goals, objectives 

and determining who, what, when and how the objectives will be met. 

The Goal - implementing NFIRS 5.0 - has several objectives that need to 

be achieved for the system to be operational. Each objective has specific 

tasks that may be dependent on the completion of other tasks or objectives.

Following are several benefits gained from using an action plan process 

for NFIRS 5.0 implementation:

•	 To provide a management tool for achieving a successful implementation

•	 To give the project a focus and direction

•	 To furnish a blueprint for management to monitor project status

•	 To render a shared view of the project that leads to improved teamwork and cohesiveness

Following this section is a sample action plan for implementing NFIRS 

5.0. The objectives are clearly measurable and the tasks for each objective 

have a clearly defined start/stop date and responsible party. It is best to 

keep timeframes for each objective under 6 months. Objectives that take 

longer than 6 months may be jeopardized by changing requirements and 

budgets.

The sample action plan objectives, tasks and time frames are dependent 

on the jurisdiction’s operating environment. Changes will be required to 

tailor the plan to your jurisdiction. For example, budget approvals and 

contract awards may be done outside the organization and can take significantly longer to complete. This plan also assumes that any custom development can be completed in 8 weeks. This may be an underestimate if 

the work is being done by another governmental agency.

Section 5

STANDARD USFA 

SOFTWARE IMPLEMENTATION 

GUIDELINES

State Software 

The United States Fire Administration has developed a standard software 

package which states may use to implement the NFIRS 5.0 standard described in this specification. Entities that choose not to develop their 

own NFIRS 5.0 compliant software may use the USFA provided standard 

software. The USFA software package consists of the following software 

components:

Data Entry Tool

The USFA Data Entry Tool provides the user the ability to enter, validate 

and maintain NFIRS 5.0 compliant incident information. The software 

can be used by departments to enter incidents and by the state NFIRS 

program manager to enter paper incidents and to manage the state database of reported incidents.

The Data Entry tool supports all paper forms associated with the national 

standard. In addition, the tool includes support for a number of options 

that provide states and local departments the ability to setup information 

outside the national standard. This includes the following: 

Plus+ One Codes: Every coded field included in the national standard 

allows for one additional level of specificity, definable by the state. For 

example, if the national standard for a code is three digits, a fourth 

digit is provided for the states to provide more specific responses.

State and Local Information: To encourage states and local fire departments to participate, additional state and local fields may be captured 

using the Data Entry Tool. (Note: This information needs to be setup 

in the system using the Program Administration Tool, which is discussed below).

Special Studies: Special Studies track specific coded responses for information that is captured only for a specific period of time. These 

studies may be performed at the national, state and/or local level. This 

information can be setup and maintained using the Data Entry tool.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

STANDARD USFA SOFTWARE IMPLEMENTATION GUIDELINES

354

Fire departments interested in using the USFA standard data entry software must contact their state NFIRS program manager to see if the standard USFA software will be supported by their state. States choosing to 

provide the standard USFA data entry software to their departments must 

provide all technical and help-desk support for the software. If states lack 

resources to provide software support they may choose to implement 

other software options.

Data Validation Tool

One of the key objectives of the new NFIRS was to provide validation of 

incident information against the national standard at the earliest possible 

point in the reporting process, regardless of the tool used to enter the incident information. If the information is entered via the USFA Data Entry 

Tool, validation is automatically performed as the information is being 

entered.

For those choosing to enter incident information via 3rd party or custom 

systems, the USFA Data Validation Tool can be used to validate a delimited 

flat file containing the incident information. These delimited flat files will 

serve as the lowest common denominator between the national NFIRS 

tools and other NFIRS 5.0 compliant systems.

The process of validating incident information begins by reading all the 

records in the delimited flat file associated with a particular incident exposure. If all records are read successfully, this information is then validated against all codes and rules defined at the national level, as well as 

any additional state and local information requirements.

Data Conversion Tool

Many states and local fire departments will continue to report incidents 

using the NFIRS 4.1 standard. Another key objective for the new system 

is the ability to store and report on information entered in both 4.1 and 

5.0 compliant systems. The new NFIRS 5.0 data structure will support 

the storage and reporting of NFIRS 4.1 compliant data. This data can be 

validated after entry and before transmission to the next level of the reporting process, using a process similar to that used in the USFA Data 

Validation Tool. NFIRS 4.1 data will go through the following conversion/validation processing as part of the NFIRS 5.0 system.

•	 NFIRS 4.1 data will be mapped to the NFIRS 5.0 format

•	 NFIRS 4.1 data will be marked as 4.1 data

•	 NFIRS 4.1 data will be validated against 4.1 rules

Program Manager Administration Tool

The new NFIRS 5.0 system is a dynamic, rules based system, which provides for state and local information needs. NFIRS Program Managers can 

use the USFA Program Manager Administration Tool for two main purposes.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION 355

STANDARD USFA SOFTWARE IMPLEMENTATION GUIDELINES

First, this tool is used to enter and maintain state and local information 

requirements, including the following:

•	 Plus+ One Codes

•	 State Specific Rules and Actions

•	 State and Local Information

- Coded Information 

- Numerical Information

- Textual Information

- Date/Time Information

Second, this tool is used by states to “Release” their information within 

the national database for national analysis. All participating states are given ultimate control over when their information can be used for national 

analysis. In an effort to encourage states to send their information more 

frequently during the year, and as a safeguard for states who opt to store 

all their incident information on the national database, each state is responsible for releasing their information for national analysis. Two key 

points should be noted in reference to releasing incident information.

•	 Only valid incidents may be released for national analysis.

•	 Releasing incidents does not include sensitive information (names, 

addresses, etc.). For details on security levels for sensitive information fields See “System Field Security Levels” on page 112.

System Administration Tool

The system administration tool is used for the day-to-day technical operation of the NFIRS 5.0 system. This tool is used for the following functions:

•	 Maintain users and user groups.

•	 Assign NFIRS service permissions to user groups.

•	 Manage NFIRS services.

•	 View system performance statistics.

Reporting Environments

The NFIRS 5.0 system offers three different reporting environments, designed to accommodate the various needs of different users within the 

NFIRS community; the reporting environments are as follows:

•	 FEMA Intranet Reporting.

•	 WWW Internet Reporting.

•	 Direct Data Access (ODBC) Reporting.
NFIRS VERSION 5.0 DESIGN DOCUMENTATION

STANDARD USFA SOFTWARE IMPLEMENTATION GUIDELINES

356

Implementation Options

For states choosing to use the Standard NFIRS 5.0 software there are two 

implementation options:

Implementation Using National Database

States may choose to use the FEMA National Database Server as their primary storage for incident information. Each state database resides in its 

own protected area on the FEMA server. Hardware and database maintenance, backups and system performance handling is performed by FEMA 

and USFA. Database management is done via the FEMA WAN by the 

state NFIRS program manager using the software components described 

above. These system software components are part of standard, USFA 

provided client software which resides on a computer in the state NFIRS 

program office. If data entry occurs at the state level, incident information may be entered directly into the national database via the NFIC Data 

Entry Tool. This entry may be accomplished only via the FEMA WAN. Local data entry, for a state which has implemented the NFIRS 5.0 System 

using the national database requires the use of a local database when 

entering information via the NFIC Data Entry Tool.

The second option available to states is to allow states that desire a local 

version of the NFIRS 5.0 system access to the various system components for local implementation. This will require a local installation of 

the national Server based components and the use of an ORACLE database. States that choose this option will be required to provide their 

own hardware, disk storage, hardware maintenance, ORACLE Database 

Administrator (DBA), ORACLE maintenance and database backups. This 

step in implementation will occur only after the various components are 

determined to be stable under option one above. The following diagram

States that decide to develop their own state level software using this 

specification as a guide must use the second option described above with 

the following additional differences:

•	 The state must develop its own system and client software components.

•	 The state may choose to use a database other than ORACLE and transmit incidents through the Open Database Connectivity Standard 

(ODBC) or by using the standard Flat Transaction File format.

Hardware and Software 

Implementation Requirements

PLEASE NOTE: These requirements are subject to change pending final release of 

this specification!

National Fire Data Center Hardware and Software

At the national level, database sizing and usage estimates were used to 

specify the national database and web server. Database estimation factors 

included the following:

•	 National database server slated to hold 7-9 million incidents per year 

for the first three years.

•	 EMS incidents will total 80% of all incidents nationwide.

•	 15,000 Fire Service casualties per 1,000,000 Fires.

•	 15,000 Civilian casualties per 1,000,000 Fires.

•	 Database overhead for indices, views, etc. estimated at 100% raw data 

size.

From these estimates, the following hardware and common off-the-shelf 

software (COTS) were chosen for the national database server.
