FOREWORD

In 1972, the President’s Commission on Fire Prevention and Control published America Burning. This document was the first in-depth discussion of this country’s fire problem. An 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 P.L. 93–498 mandate to collect national data on fires was the establishment of the 

National Fire Incident Reporting System (NFIRS). In 1976, six States piloted what eventually evolved into 

NFIRS. The U.S. Fire Administration (USFA), a component of the Department of Homeland Security (DHS), 

developed NFIRS as a means of assessing the nature and scope of the fire problem in the United States.

NFIRS has grown in both participation and use. Over the life of the system, all 50 States, more than 40 

major metropolitan areas, and more than 15,000 fire departments have participated in NFIRS. On a yearly 

basis, approximately 600,000 fire incidents and more than 5 million non-fire incidents are added to the 

database. NFIRS is the world’s largest collection of incidents to which fire departments respond.

NFIRS data are used at all levels of government. At the local level, incident and casualty information is used 

for setting priorities and targeting resources. The data now being collected are particularly useful for designing fire prevention and educational programs and emergency medical service (EMS)-related activities 

specifically suited to the real emergency problems the local community faces.

On the State level, NFIRS is used in many capacities. One valuable contribution is that NFIRS data are used 

by State legislatures to justify budgets and to pass important bills on fire-related issues such as sprinklers, 

fireworks, and arson.

Many Federal agencies, in addition to USFA, make use of NFIRS data—the Consumer Product Safety Commission (CPSC), the National Highway Traffic Safety Administration (NHTSA), the National Institute of 

Standards and Technology (NIST), to name a few. The CPSC has found NFIRS very useful in identifying 

potentially hazardous products.

Nationally, NFIRS is used by various private industries, including national associations for home appliance 

product manufacturers, the hotel and motel industry, insurance companies, and attorneys.

Because NFIRS is a voluntary system, not all States or fire departments within States participate. In 1977, 

only 6 States regularly reported data to the National Fire Data Center (NFDC), and 19 others had data systems in some stage of development. Since then, participation has increased significantly so that an estimated 44 percent of all U.S. fires to which fire departments respond are captured in NFIRS.

States have the flexibility to adapt their state reporting systems to their specific needs, and reporting by 

localities is voluntary. Therefore, the design of a state’s data collection system varies 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.

NFIRS 5.0 COMPLETE REFERENCE GUIDE viii

As participation in NFIRS increased, the system itself has undergone revisions and updates. The latest update of the system is Version 5.0, which provides many improvements both from the standpoint of those 

who submit the data and for those who use it. This reference guide provides step-by-step instructions for 

submitting fire incident information to NFIRS 5.0. 

Comments and suggestions on further improvements to this guide are solicited and should be submitted to National Fire Data Center, U.S. Fire Administration, Department of Homeland Security, 16825 South

provides both instructions for reporting data to NFIRS Version 5.0 and an understanding of the data elements collected by the system. It also serves as a reference for the coding of the data. NFIRS (pronounced 

“en-furs”) is a tool that fire departments use both to report fires and other incidents to which fire departments respond and to maintain records of these incidents in a uniform manner.

NFIRS 5.0 is a modular, all-incident reporting system designed by the U.S. Fire Administration (USFA), a 

part of the Department of Homeland Security (DHS), with input from the fire service and other users of 

the data.

How NFIRS Works

In 2001, more than 12,000 fire departments participated in NFIRS. After responding to an incident, fire 

department personnel complete one or more of the NFIRS “modules.” The information in these modules 

describes the kind of incident responded to, where it occurred, the resources used to mitigate it, and how 

losses and other information designed specifically to understand the nature and causes of fire, hazardous 

material (HazMat), and emergency medical service (EMS) incidents. Information is also collected on the 

number of civilian or firefighter casualties and an estimate of property loss. The uniformity of definitions 

used in coding NFIRS fields makes aggregation of national data possible.

Information is entered about an emergency response either manually on a form or directly through a computer. Local agencies forward the completed NFIRS modules 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 transmits the data to the National Fire Data Center (NFDC) at the USFA. 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, determine consumer product failures, identify the focus for research efforts, and support Federal 

legislation. NFIRS is the primary source of data for a wide range of analyses and reports, including USFA’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 United States.

At the national level, data combined from participating States are also used by information partners, as 

shown in the following graphic.

NFIRS Version 5.0 Enhancements

NFIRS 5.0 is an information-based system with data entry, data storage, and data retrieval, whether for a 

single incident or in aggregate, aggregated via a computer that interacts with the database. Because not all 

fire departments use computers for their recordkeeping, paper forms are available. Paper forms are forwarded to a central point where the data are entered to a database. This guide provides detailed instructions 

for completing paper forms. Automated reporting systems, however, should be designed to capture the data 

in the same order as these paper forms, so this guide is relevant to anyone who must collect and report 

incident data.

In Version 5.0, a series of descriptions with assigned code numbers is used to describe incidents. Many of 

these descriptive phrases were created by the National Fire Protection Association (NFPA) and published in 

NFPA 901, Standard Classifications for Incident Reporting and Fire Protection Data, 1995 edition. Appropriate codes are 

included in this user guide. Many improvements that have been incorporated into Version 5.0 are the result 

of suggestions made by participating fire departments, State agencies, and the National Fire Information 

Council (NFIC).
INTRODUCTION

NFIRS 5.0 COMPLETE REFERENCE GUIDE 1-4

The type and content of data collected by NFIRS 5.0 have evolved over more than 25 years and are based 

on the participation of all 50 States and more than 40 metropolitan fire departments. NFIRS 5.0 captures 

information on all incidents to which a fire department responds. In addition to many data coding improvements, Version 5.0 provides five new modules that recognize the increasingly diverse activities of fire 

departments today: an EMS Module, a Wildland Fire Module, an Apparatus Module, a Personnel Module, 

and an Arson Module. Other modules have been extensively revised.

The modular design of NFIRS 5.0 makes the system easier to use than previous NFIRS versions because it 

captures only the data required to profile the extent of the incident. Some fires, for example, require just 

basic information, whereas others require considerably more detail. The accuracy and reliability of the collected data are improved because of the way questions are asked and data are coded. 

The selection of data elements and the coding selections for the data have been revised to reduce confusion or improve data quality. For example, codes using 9 to indicate “not otherwise classified” have been 

changed to the value of 0 (zero) where it may be necessary to code something as “other.” The internal 

codes for “insufficient information to classify further” have been eliminated. A single code of “U” (or 

“UU” or “UUU” depending on field size) is available to designate “unknown” or “undetermined.” Although NFIRS Version 4.1 allowed a distinction between the 9 code (“not otherwise classified”) and the 0 

code (“insufficient information to classify further”), the distinction between these codes was often unclear 

to the respondent.

Other improvements incorporated in NFIRS 5.0 include:

•	 Compound data elements have been eliminated. Some of the previous data elements asked for multiple 

pieces of information. NFIRS 5.0 splits these data elements into single-issue questions to eliminate 

often confusing and ambiguous or incorrect answers. Although this increased the number of fields or 

questions being asked, the choices are clearer and the number of codes has decreased. For example, 

“Equipment Involved in Ignition” in Version 4.1 is a complex list of equipment that not only identifies 

the equipment, but also includes data on its power source and portability. Version 5.0 has three categories (Equipment, Equipment Portability, and Equipment Power Source) that makes coding easier, more 

accurate, and more specific.

•	 Contained, no-loss fires are simply reported using only the Basic Module, with as few as three codes 

having to be looked up and entered when using the paper forms.

•	 Small spills of common hazardous materials are documented only in the Basic Module instead of requiring the fire department to complete all the details that are necessary for spills that are more significant. Detailed information is completed on the HazMat Module (NFIRS–7) if a serious release of 

hazardous materials occurs.

•	 Reporting the failures of protective clothing and equipment worn or used by firefighters has been simplified to focus only on items whose failure contributed to a casualty (i.e., injury or fatality).

For convenience to users familiar with the codes of NFIRS 4.1, references are provided in this guide to the 

titles of the NFIRS 4.1 code lists that have changed in NFIRS 5.0.

INTRODUCTION

Benefits of NFIRS to Firefighters

Firefighters will find that NFIRS 5.0 is easier to use than previous versions. Also, two of the new modules, 

Apparatus and Personnel, will assist fire departments in managing apparatus, personnel, and resources. 

Each fire department is responsible for planning and managing its operations so that firefighters can perform their roles of fire control and fire prevention most effectively and efficiently. The availability of accurate information about fires and other incidents is vital in achieving maximum performance. 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' performance.

Coding

In 1963, NFPA formed a technical committee to devise a uniform system of fire reporting to encourage 

fire departments to use a common set of definitions. NFPA 901, Standard Classifications for Incident Reporting and 

Fire Protection Data, was developed as a dictionary of fire terminology and associated numerical codes. As the 

fire service gained experience with this fire data “language,” continuous improvements have been possible. 

The set of codes used in NFIRS 5.0 represents the merging of the ideas from NFPA 901 with the many suggested improvements from users of the NFIRS 4.1 coding system.

Structure of the User Guide

Chapter 2 briefly describes the 11 NFIRS modules, provides general guidance on when each module 

should be used, and details standard conventions that are to be used when completing these modules. 

Chapters 3 through 13 cover NFIRS modules 1 through 11, respectively, in detail. Guidance is provided on 

how each field of the module form should be completed and defines the codes that are used in the system. 

Chapter 14 addresses information that might be submitted on a supplemental form (NFIRS–1S). Full-size 

replicas of all NFIRS forms are found in Appendix A.

Appendix B is an index of NFIRS 5.0 synonyms of selected code lists that have been alphabetized. Appendix 

C is a glossary of terms and abbreviations. Appendix D is an alphabetized listing of chemicals and hazardous materials.

NFIRS 5.0 MODULES

NFIRS 5.0 COMPLETE REFERENCE GUIDE
NFIRS 5.0 COMPLETE REFERENCE GUIDE 2-2

Chapter 2•NFIRS 5.0 Modules

NFIRS Version 5.0 consists of 11 modules. The Basic Module is to be completed for every incident, with 

additional modules used as appropriate to describe the incident.

Description of Modules

The Basic Module (NFIRS–1) captures general information on every incident (or emergency call) to which 

the department responds.

THE FOLLOWING MODULES ARE USED IN CONJUNCTION WITH THE 

BASIC MODULE, WHICH MUST BE COMPLETED FOR EVERY INCIDENT TO 

WHICH YOUR DEPARTMENT RESPONDS

The Fire Module (NFIRS–2) is used to describe each fire incident to which the department responds. For 

wildland fire incidents, the Wildland Module can be used instead of the Fire Module if that option is available by your State reporting authority.

The Structure Fire Module (NFIRS–3) is used to describe each structure fire to which the department responds. This module is used in conjunction with the Fire Module.

The Civilian Fire Casualty Module (NFIRS–4) is used to report injuries or deaths to civilians or other emergency personnel (e.g., police officers, non-fire department/EMS personnel) that are related to a fire incident. 

This module is used in conjunction with the Fire Module and, if applicable, the Structure Fire Module. 

Non-fire-related injuries or deaths to civilians can be reported on the EMS Module.

The Fire Service Casualty Module (NFIRS–5) is used to report injuries and deaths of firefighters. The module 

can also be used to report the exposure of a firefighter to chemicals or biological agents at an incident 

where that exposure does not result in any symptoms at that time but that manifest themselves at a later 

date. This module may be used with any of the other modules.

THE FOLLOWING MODULES (NFIRS–6 THROUGH –11) ARE 

OPTIONAL MODULES THAT ARE USED ONLY WHEN THAT OPTION(S) IS 

SELECTED BY YOUR STATE REPORTING AUTHORITY

The EMS Module (NFIRS–6) is completed by fire departments that provide emergency medical services. The 

module is used to report all medical incidents where the department provided the primary patient care. 

This includes incidents where there were civilian fire-related casualties and a Civilian Fire Casualty Module 

was completed and where there were firefighter fire-related casualties and a Fire Service Casualty Module 

was completed. (This module does not serve as a patient care record, but it can be used in conjunction 

with the local requirements for patient care.)
2-3 NFIRS 5.0 COMPLETE REFERENCE GUIDE

The Hazardous Materials Module (NFIRS–7) is completed to report spills or releases of 55 gallons or more of 

hazardous materials or when special HazMat actions were taken. As appropriate, the module is used in conjunction with the Fire Module or other modules to provide detailed information about incidents involving 

hazardous materials.

The Wildland Fire Module (NFIRS–8) is completed to report incidents that involve wildland or vegetation 

fires. The module is used in lieu of the Fire Module for wildland fire incidents.

The Apparatus or Resources Module (NFIRS–9), a department-use module, is completed to report data specific 

to each piece of apparatus that responds to an incident. It includes information that can be used to calculate response time and time out of service. This module is not used if the Personnel Module is used.

The Personnel Module (NFIRS–10), a department-use module, is completed to report the same information 

as on the Apparatus or Resources Module, but it also provides for tracking the personnel associated with 

that apparatus.

The Arson Module (NFIRS–11) is completed to report additional information on fires that have been coded 

by the department as “intentionally set.” 

In addition to the 11 modules, a Supplemental Form (NFIRS–1S) can be used to report information on additional persons and entities involved in the incident and to collect additional special studies fields. This 

paper-only form extends the amount of information collected in the Basic Module. 

Preparation of Modules

Both local and State agencies should establish standard procedures on how to complete the NFIRS reporting modules and how to submit the modules to the State reporting activity. These procedures will help 

ensure consistency in the data received and provide guidance to those filling out the modules. Each coded 

field in the on-line NFIRS systems has the capability to be expanded by another alpha-numeric character so 

that information more specific than the national standard addresses can be collected.

The majority of the information on the modules is obtained at the scene by emergency responder personnel. An emergency responder at the scene should be assigned the responsibility of recording the required 

information concerning each incident. To gather additional information or to confirm one’s own impressions, the individual completing the module should contact others involved with the incident. Contacts 

may include on-scene fire service personnel, police and civilians at the scene, the dispatcher, EMS personnel, hospital staff, fire and building inspectors, the arson investigator, the local fire module coordinator, and 

State-level officials responsible for coordinating the reporting system. Most importantly, the module should 

reflect exactly what happened.

Once the module has been completed, the information should be reviewed at the local level before it is 

signed by the officer in charge at the incident and by the individual completing the module. Originals 

of the modules should be kept for departmental use and files, and copies forwarded to the State that will 

transmit them to the NFDC.

Modifications to original incident reports can be submitted later when additional information becomes 

available or if any of the original information changes or is found to be incorrect. A person injured in a fire 

who dies within 1 year as a result of the injuries is an example of the type of new information that could 

be cause for submitting a “change report.” 

Once computerized, the data can be presented in a variety of ways, such as summaries, comparisons, and 

reports. The web-based reporting tool made available to NFIRS users by the NFDC is able to produce a variety of reports. Many localities and departments develop data analysis and display programs to meet their 

own requirements. For more information concerning the new NFIRS 5.0, contact the USFA or visit its Web 

site at http://www.usfa.fema.gov/fireservice/nfirs/

Conventions Used in Completing Modules

Each time a fire service unit moves in response to an alarm, the Basic Module (NFIRS–1) must be completed. One report is completed for each incident. Other modules are completed as appropriate.

A form depicting the data for each module is shown at the beginning of that module’s chapter. The entire 

set of forms (full-size) is included in Appendix A. The forms are divided into lettered sections, and blocks 

divide sections. Blocks are formed by the section letter and the number of the block within the section 

(e.g., Section A, Block A1). The different blocks within a section contain related information. The modules 

are designed to help emergency personnel report incident information in a straightforward and orderly 

manner. Many of the codes are printed on the paper modules to expedite the report process. For many situations, however, the correct codes will need to be looked up.

Modules should be completed according to the type of incident being reported. Instruction is given on the 

module when necessary. All sections that have a star (P) by the title are required fields. Throughout this guide, notes 

or important considerations are indicated with a pointed finger (*).

Each module is discussed one section at a time in the chapters that follow. Each item or block in each section is described by its definition, purpose, entry, and example. In addition, for those items requiring a 

numerical code, the codes and a coded example are shown.

• The definition provides a common meaning for all, which ensures consistency in understanding and application.

• The purpose gives a brief explanation as to why the information has been requested; it may also indicate

how the information could be of additional use.

• The entry provides guidance on the type of information to place in the entry block.

• The example shows how the entry might look for a particular situation.
NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 2 • NFIRS 5.0 MODULES

Within the data coding used in this system, a few conventions assist in reporting. The letters “N,” “NN,” or 

“NNN” are used to indicate “none” in a field that is normally coded. The letters “U,” “UU,” or “UUU” are 

used to indicate “unknown” or “undetermined” in a field that is normally coded. If the field is a numeric 

field such as dollar loss, 0 (zero) is used to indicate none. Numeric fields such as dollar loss can be left 

blank if a value is unknown or if the incident is not a fire.

The coded field should not be left blank as that is an indication that the person completing the report 

missed it or forgot to fill it out. 

Please note that the numbers “0,” “00,” or “000” are valid codes for many coded fields. These have the 

value for “other” and are intended to be used where the item or issue being coded is identifiable but the 

code selection list does not contain the description of what has been identified for that data element. In 

some data elements, codes ending in “0” allow for further identification of the item or issue, as in the case 

where part of the answer is known but not enough to code it at the specific level required by the options 

in the list.

The entry of data into fields should follow the following conventions:

•	 Text fields should be left justified.

•	 Numeric fields should be right justified.

•	 Coded fields do not need to be justified since they should fit the entry space exactly.

Fire Department Header

Before data may be entered into NFIRS 5.0, each fire department must have established a header record. 

This record is established only once in the system and then updated whenever there is a change in the 

department’s information.

Creation of or changes to the header record must be reviewed or approved by each department’s State 

NFIRS program manager.

As a rule of thumb, if a department has a Fire Department Identification (FDID) number, a header has already been established. Most of the existing records were created from the conversion of NFIRS 4.1 header 

records at the State level; however, many of the fields may be blank because they are new to NFIRS 5.0. It is 

recommended that each department review their header record to ensure completeness. 

The table on the following page shows the fire department header fields:

Chapter 3 • Basic Module (NFIRS-1)

The purpose of the Basic Module is to collect information common to all incidents. The Basic Module is required for every type of incident to which a department responds. 

Entries in the Basic Module determine what other modules need to be completed based on the type of 

incident involved. For example, fire incidents are also reported on the Fire Module (NFIRS–2). Additionally, 

the Structure Fire Module (NFIRS–3) is required if the fire reported in the Fire Module occurs in a structure. 

A separate Civilian Fire Casualty Module (NFIRS–4) is required for each civilian who is injured as a direct 

result of a fire incident. A separate Fire Service Casualty Module (NFIRS–5) is required for each firefighter 

who is injured in response to an alarm whether or not a fire was involved.

Optional modules include the EMS, HazMat, Wildland Fire, Apparatus and Personnel, and Arson Modules. 

The type of incident reported or the nature of a particular incident, such as the release of hazardous materials 

at a fire after the arrival of the fire department, may trigger one or more of these additional modules. The 

amount of information needed in each module varies based on the type of incident, associated casualties, 

and property losses.

SECTION A

The field elements in Section A that are marked with a star (P) are required to be completed. Combined, 

these fields (FDIC, State, Incident Date, Incident Number, and Exposure) uniquely identify each incident.

Fire Department Identification (FDID) P

Definition

A unique five-character identifier assigned by the State to identify a particular fire department within the 

State. This identifier may also identify the county, fire district, or other jurisdiction in which the fire 

department is located. Many States use the two left-most digits to identify the particular department within 

a jurisdiction. All five spaces in this field must be occupied by numerals or alphanumeric characters. If the 

FDID is less than five characters, use leading zeros.

Purpose

The FDID number is used to identify incident data that have been collected and reported by individual 

departments. Feedback on local or regional incident experience can then be prepared and sent to 

individual agencies or specific fire departments. 

Entry

Enter the State-assigned FDID.

individual stations. Specific feedback on incident experience can then be prepared and sent to individual 

stations. The station number is also useful for analyzing different levels of activity within a fire department.

Entry

Enter the station number in the space provided. The fire department should determine which station 

number should be entered (e.g., first arriving unit, station’s area). The station number is left justified. Leave 

blank if there is only one station in the department.

The Incident Number is a sequential number and is numeric only; it is not an incident identification 

number.

Purpose

In conjunction with other required Section A fields, this element uniquely identifies each incident.

Entry

Enter the number assigned to the incident. The number may be assigned at the local, county, or district 

level, depending on policies. It may be necessary to obtain this number from an alarm or dispatch center. It 

must be unique for each incident on a given day.

Exposure Number P

Definition

Exposure is defined as a fire resulting from another fire outside that building, structure, or vehicle, or a fire 

that extends to an outside property from a building, structure, or vehicle. For example, if the building fire 

ignites a truck parked outside, the truck fire is an exposure fire.

In the case of buildings with internal fire separations, treat the fire spread from one separation to 

another as an exposure. Treating multiple ownership of property within a building (e.g., condominiums) as exposures, unless separated by fire-rated compartments, is discouraged.
3-8 NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 3 • BASIC MODULE (NFIRS-1)

The P denotes a required field.

A

Purpose

Although the Incident Number permits all properties involved in a fire incident to be related together, 

the Exposure Number identifies each separate property type involved in the fire. This makes it possible to 

capture the specific details of the fire in each exposure and to relate all the exposures to the basic incident, 

if necessary. The Exposure Number, in conjunction with other required Section A fields, uniquely identifies 

each incident itemized in Section C.

When a fire involves more than one building, each building fire should be considered a separate fire, with 

the ignition for all but the original building fire classified as exposure fires.

Entry

In a fire involving exposures, an additional Basic Module should be completed for each exposure. Each 

module completed for an exposure should contain the same Incident Number assigned to the original 

property involved. A separate sequential Exposure Number is assigned to each exposure. The original incident is always coded “000,” and exposures are numbered sequentially and incremented by 1 beginning 

with “001.” The three-character numeric field is zero filled, not right justified.

Delete: Check or mark this box when you have previously submitted data on this incident and now want 

to have the data on this incident deleted from the database. If this box is marked, complete Section A and 

leave the rest of the report blank. This will delete all data regarding the incident. Forward the report according to your normally established procedures.

Change: Check or mark this box only if you previously submitted this fire incident to your State reporting authority and now want to update or change the information in the State database. Complete Section A and any 

other sections or blocks that need to be updated or corrected. If you need to blank a field that contains data, 

you must resubmit the original module containing the newly blanked field along with all the other original 

information in the module for that incident. This action is required only when sending an updated module 

to your State reporting authority. Forward the report according to your normally established procedures. 

No Activity: If the fire department has had no incidents during the month, a no activity report should be 

submitted. Unless otherwise specified by the State, this report should be submitted monthly according to 

your normally established procedures.

Examples

Deleting a previously submitted incident:

Check or mark the Delete box and complete all other fields in Section A exactly as they were entered in the 

original report.

Changing a previously submitted incident:

It was incorrectly reported that six firefighters responded to a fire incident. Later, the officer in charge 

corrected the information and sent in a Change report with four fire service personnel responding:

SECTION B

Section B collects information on the specific incident location.

The check box at the top of the section should be checked or marked only if the incident address is 

provided on the Wildland Fire Module (NFIRS–8). The Wildland Fire Module provides an alternative 

method of recording the incident location.

Location Type P

The location of the incident, which may be a street address, directions from a recognized landmark, or an 

intersection of two roadways.

Purpose

The exact location of the incident is used for spatial analyses and response planning that can be linked to 

demographic data. Incident address information is required at the local government level to establish an 

official document of record.

Entry

Check or mark the single box that best indicates the address type that will be entered. If the incident is a 

wildland fire, the alternate address box at the top of Section B may be checked or marked to indicate that 

the wildland location scheme is provided in the Wildland Fire module.

Street address: A normal street address. Check or mark this box and complete the address fields.

B

Intersection: There is no street address. The incident location is at the intersection of two or more streets, 

roads, etc. Check or mark this box and enter the first street in the Street or Highway field. The intersecting street(s) is entered in the Cross Street or Directions field.

In front of: No street address is available. However, the incident location is in front of an area with a street 

address. Check or mark this box and complete the address fields. An example of this might be a park, 

plaza, or common area in front of a building with a street address.

Rear of: No street address is available. However, the incident location is in the rear of an area with a street 

address. Check or mark this box and complete the address fields. An example of this might be an alley 

that runs behind a building with a street address.
CHAPTER 3 • BASIC MODULE (NFIRS-1) B

The P denotes a required field. 3-11 NFIRS 5.0 COMPLETE REFERENCE GUIDE

Adjacent to: No street address is available. However, the incident location is adjacent to an area with a 

street address. Check or mark this box and complete the address fields. An example of this might be an 

empty lot or common area that is next to a building with a street address.

Directions: No street address is available and no street address is available near the incident scene. Check or 

mark this box and enter brief directions for the location of the incident in the Cross Street or Directions 

field. If the area is along an interstate or State highway, the closest milepost should be entered in the 

Number/Milepost address field. An example of this might be a brush fire that occurs in a remote area 

or a fire that occurs on or near an interstate highway.

United States National Grid: Provides a geospatial address based on universally defined coordinate and 

grid systems and a common frame of reference across multiple jurisdictions easily extended worldwide. Using an alpha-numeric reference that overlays the UTM (q.v.) coordinate system, USNG spatial addresses break down into three parts: Grid Zone Designation, for a world-wide unique address; 

100,000-meter Square Identification, for regional areas; Grid Coordinates, for local areas. USNG improves interoperability of location appliances with printed maps through a consistent and preferred 

geospatial grid reference system. Relates to GPS (q.v.). Contributed by Tom May. (International). For more information and examples on use, see: http://www.xyproject.org/How%20To%20Read%20USNGHow%20

SECTION D

D Aid Given or Received P

Definition

Aid given or received, either automatically (i.e., prearranged) or mutually for a specific incident. These actions are defined as:

Aid Received (automatic or mutual): A fire department handles an incident within its jurisdiction with additional manpower or equipment from one or more fire departments outside its jurisdiction. Aid received 

can be either mutual or automatic aid.

Aid Given (automatic or mutual): A fire department responds into another fire department’s jurisdiction to 

provide assistance at an incident or to cover a vacated station while the receiving fire department is busy 

at an incident. Aid given can be either mutual or automatic aid. 
CHAPTER 3 • BASIC MODULE (NFIRS-1) D

Other Aid Given: A fire department covers and responds to another jurisdiction or locale that has no fire 

department. 

No Aid: A fire department handles an incident within its jurisdiction without help from adjacent or 

outside fire departments.

Purpose

Aid information can be used to study response levels necessary to control various fire and emergency 

situations. It can be used to determine the adequacy of resources at the local level and the need for 

adjusting cooperative agreements. The Aid Given or Received entry serves as data control to ensure that 

the same incident is not counted more than once while still giving credit for activity performed by 

outside departments.

Entry

Check or mark the box indicating whether aid was given or received. If no aid was given or received, 

check or mark the None box.


 Unless otherwise stipulated, whenever the following instructions indicate completion of the “Basic 

Module,” the appropriate supporting and optional modules must also be completed.

Mutual/Automatic Aid Received: If either of these boxes is checked or marked, complete the Basic Module.

Mutual/Automatic Aid Given: If your department provided automatic or mutual aid to another fire department, check or mark the appropriate aid-given box; complete their FDID, their State, and their Incident 

Number fields; and complete the Basic Module through Block G1 (Resources). No other information is 

required for the Basic Module unless a fire service casualty occurs. In this case, you must also complete 

Block H1 (Casualties) and a Fire Service Casualty Module.

Other Aid Given: Check or mark this box if your department covers and responds to another jurisdiction or 

locale that has no fire department. Complete the Basic Module. In Section D, leave their FDID and their 

Incident Number fields blank; the State field is optional.

None: Check or mark this box if no mutual aid was involved.

If the receiving fire department completes the incident, then the giving department should complete the 

required portion of the module as needed for its own documentation of the incident. This can be particularly 

important for documenting fire service casualties.

Resources: If you give aid, you may choose to report your own resources as an option (Block G1). 

Similarly, if you receive aid, you may choose to count only your own resources or count your own 

resources plus those of the aid-giving department. If you include aid-received resources, check or 

mark the corresponding box.

Casualties: The aid-receiving department reports the details on all casualties other than the fire service casualties of the aid-giving department. Each department reports the details on its own fire service casualties.

E2 Shift and Alarms

Shift or Platoon

Definition

Identifies the on-duty shift or platoon that responded to the incident. This applies only to fire departments 

with organized work force arrangements.

Purpose

Recording the shift that responded to an incident assists fire departments in determining workload balances and staffing requirements. This is a local option.

Entry

If your fire department uses this data element, enter the designation of the on-duty shift that responded to 

the incident. If the incident was of such duration that the shift changed during the control of the incident, 

record the shift change time and the designation of the new shift in the Remarks section (L).

Alarms

Definition

The actual number of alarms transmitted for the incident. The definition of an alarm is determined at the 

local level.

Purpose

The number of alarms is one method of measuring incident severity. Knowing the number of alarms can 

be useful for local analysis of resource requirements. The number of alarms also may be related to mutual 

aid support. This is a local option.

Entry

If your fire department has a standard method of designating alarms, enter the number of alarms required 

for this incident.

District

Definition

An area identified by the fire department that is useful for administrative purposes.

Purpose

Fire departments can develop their own method of locating the frequency and severity of incidents by 

district. District numbers may identify specific townships, contract service areas, political wards, station 

response areas, inspection or administrative districts, or any other boundary a department may wish to use. 

This data element can be a powerful tool for local use. This is a local option.

E3 Special Studies

Definition

Temporary data elements that can be used for collection of information that is of special interest for a 

defined period. Special studies are typically required to capture information on emerging trends, problem 

areas, or a specific issue being studied. When the answer becomes known through the special study, the 

collection of that field is no longer required. If the data will always be needed for permanent collection, a 

State- or department-defined permanent user field should be created and used instead of the Special Studies field. A State, a fire department, or the NFDC can define special studies.

Special Study ID Number: This number uniquely identifies each special study that is being run by the fire 

department, State, or NFDC.

Special Study Value: The value in the field being collected. Responses for special studies can be defined as 

codes or as alphanumeric entries of numeric values or dates. States, fire departments, and the NFDC can 

define Special Studies fields.

Purpose

The use of special studies allows departments, States, and the NFDC to quickly collect information on an 

issue or problem and to answer a specific question through the temporary use of a special study field over 

a defined period of time. This is a State or local option.

Entry

If you are participating in a Special Study, your entry will depend on the type of data being collected. Use 

the codeset defined for the particular Special Study field if it is a coded entry. The data entered may also be 

a date or a numeric entry if the field has been so defined. Additional Special Study fields are available on the 

Supplemental Form (NFIRS–1S).

D4 Type of Material First Ignited

Type of Material First Ignited was known as Type of Material Ignited in NFIRS 4.1.

Definition

The composition of the material in the item first ignited by the heat source. The type of material ignited 

refers to the raw, common, or natural state of the material. The type of material ignited may be a gas, flammable liquid, chemical, plastic, wood, paper, fabric, or any number of other materials.

This field is required only if the Item First Ignited code is “00” or a code less than “70.”

Purpose

This information assists in determining why fires start and spread and their severity. A study of this entry 

also helps assess the need for flammability and other material characteristic standards. This information is 

important to manufacturers for product improvement, as well as for fire prevention efforts.

Entry

Enter the code and description that best describes the type of material first ignited by the heat source.

Be certain to enter the first material ignited by the heat source. For example, if an arsonist poured gasoline on a wooden floor, it was the gasoline and not the wood that was the material first ignited.

If an insulated wire short circuits, it may be the wire’s insulation that was first ignited; or it may be the 

wood studs in the wall, thermal insulation nearby, or another material.

Example

A board game (45) made of cardboard (60) ignited (81) after being left too close to the living room fireplace (14), causing a fire:

Definition

The piece of equipment that provided the principal heat source to cause ignition.

Purpose

Analysis of the equipment involved in ignition is useful for improving product safety and preventive maintenance. It is just as important to know the kind of equipment that was used improperly as it is to know 

the kind of equipment that malfunctioned. Misuse can be the direct result of the way the equipment is 

designed and constructed. When involved in ignition, equipment information provides an important part 

of the causal data. Equipment involved in ignition can be compared to other causal data to determine if the 

equipment was (or was not) operating properly.

CHAPTER 5 • STRUCTURE FIRE MODULE (NFIRS–3)

The Structure Fire Module (NFIRS–3) should be completed for all structure fires. A structure is an assembly of materials forming a construction for occupancy or use to serve a specific purpose. This includes, 

but is not limited to, buildings, open platforms, bridges, roof assemblies over open storage or process 

areas, tents, air-supported structures, and grandstands. Users may also optionally complete the Fire Module 

for confined building fires (Incident Types 113–118), although it is not required.

Like the other modules, the Structure Fire Module is divided into sections and further subdivided into 

blocks. Only Block I1 must be completed for all structure fires. Completion of the remainder of the module is required only for building fires, although that portion of the module may also be completed for 

non-building structure fires if desired.

SECTION I

This section collects information about the structure involved in the fire, including its type, current status, 

height, and size.

I1 Structure Type P

Definition

The identification of a structure as a specific property type. 

Purpose

Information on the structure type, combined with other structural characteristics, is useful for understanding fire behavior and provides assistance in targeting fire prevention or protection efforts.

Entry

Check or mark the box best indicating the type of structure involved in the fire. If the fire was in an enclosed building or a portable or mobile structure, complete the rest of the module.

0 Structure type, other.

I2 Building Status P

Definition

The operational status of the building involved in the fire. This element indicates the actual use of the 

building at the time of the fire.

Purpose

Building status, combined with other structural characteristics, is useful for understanding fire behavior, 

the potential for loss of life and property, and the likely effectiveness of fire protection that existed before 

the fire.

Entry

Check or mark the box best indicating the status of the building involved in the fire.

Example

A family of four occupied the house (2):

7 Being demolished.

0 Building status, other.

U Undetermined.

I3 Building Height P

Definition

The number of stories at or above grade level and the number of stories below grade level in the fire building.

Purpose

Building height and depth below grade, combined with other structural characteristics, are useful for 

pre-fire planning as well as for gaining a better understanding of fire behavior. Some fire departments use 

building height and depth to determine life safety hazard values. The more difficult it is for people to escape, the higher the life safety hazard value for the building.

Entry

Enter the total number of stories at or above grade level and the total number of stories below grade level.

For split grades, consider the main egress point as the “at grade” portion of the building.

Do not count normally inaccessible attics, attics with less than standing height, or the roof as a story 

(i.e., the roof is counted as part of the highest story).

I4 Main Floor Size P

Definition

The size of the main floor in square feet. This is an estimate.

Purpose

Main floor size, combined with other structural characteristics, is useful for evaluating firefighting operations and the need to allocate resources based on size and complexity of structures. It also helps in understanding the potential life and property at risk.

SECTION J

This section collects information on where in the structure the fire originated, how far the fire spread, and 

the number of stories damaged by flame.

J1 Fire Origin P

Definition

Identifies the story where the fire originated within the building.

Purpose

The story of fire origin, combined with other structural characteristics, is helpful for gaining a better understanding of fire behavior and identifying any special problems in fire strategy and tactics. Information 

on the frequency and nature of above- or below-grade-level fires is needed for assessing aerial apparatus 

needs and performance. A fire in the upper levels of a high-rise building is often difficult to control because of delays in moving personnel and equipment to the fire floor.

Entry

Enter the story of fire origin. If below grade level, check or mark the Below Grade box.

Checking or marking the Below Grade box has the effect of entering a negative number in NFIRS 5.0.

Example

The fire began in the master bedroom on the second story:

J2 Fire Spread P

Definition

The extent of fire spread in terms of how far the flame damage extended. The extent of flame damage is the 

area actually burned or charred and does not include the area receiving only heat, smoke, or water damage. 

Purpose

In combination with other information, this element describes the magnitude or seriousness of the fire. It 

can be used to evaluate the effectiveness of built-in fire protection features or the effectiveness of the fire 

suppression force relative to the conditions faced. The confinement and extinguishment of a fire is influenced by many factors. Fire spread indicates the combined effect of these conditions. Also, the analysis of 

fire spread over many fires can reveal the effects of individual factors.

Entry

Check or mark the box best describing the extent of fire spread. 

If the fire was confined to the object of origin, an entry should have been made in Block D3 of the Fire 

Module. Do not check or mark any additional box in this block.

A room is a partitioned part of the inside of a building. If the flame damage extends beyond the area 

of origin in a one-room building, such as a shed, the damage should be described as Confined to the 

Building of Origin. The Confined to the Building of Origin box is also the appropriate description if the 

fire was on the roof or outside wall of a building.

CHAPTER 6 • CIVILIAN FIRE CASUALTY MODULE 

(NFIRS–4)

The Civilian Fire Casualty Module should be completed whenever there are civilian casualties resulting 

from a fire. A fire casualty is a person who is injured or killed as a result of a fire, including injuries or deaths 

from natural or accidental causes sustained while involved in the activities of fire control, attempting 

rescue, or escaping from the dangers of the fire. Fires include Incident Types 100–199 as recorded on the 

Basic Module, Section C. 

If a civilian injury is not directly related to fire, it may be reported on an EMS Module with the same 

incident ID information.

A separate Civilian Fire Casualty Module is required for each fire casualty.

SECTION A

The guidance and directions for completing Section A of the Civilian Fire Casualty Module are the same 

as for Section A in the Basic Module. It is stressed that the entries in Section A of the Civilian Fire Casualty Module must be identical with the entries on the corresponding Basic Module. If injuries occur in an 

exposure fire, the casualty report should have the same entries as those from Section A of the Basic Module 

for that exposure fire. An example of a completed Section A can be found on page 3–8.

CHAPTER 7 • FIRE SERVICE CASUALTY MODULE 

(NFIRS–5)

The Fire Service Casualty Module is used to report all injuries, deaths, or exposures to fire service personnel. This includes casualties that occur in conjunction both with incident responses and with nonincident events such as station duties or training.

Important: In the event of a non-incident casualty, it is critical that an EMS incident report is created in 

the system and that it is treated as if the same department with the injury responded to the EMS. 

A health exposure occurs when fire service personnel come in contact with a toxic substance or harmful 

physical agent through any route of entry into the body (e.g., inhalation, ingestion, skin absorption, direct 

contact). These exposures can be reported regardless of the presence of clinical signs and symptoms. An 

exposure fire, which is captured in Section A of the Basic Module, is not the same as a health exposure to personnel. 

A separate Fire Service Casualty Module is required for each casualty or health exposure.

SECTION A

The guidance and directions for completing Section A of the Fire Service Casualty Module are the same 

as for Section A in the Basic Module. It is stressed that the entries in Section A of the Fire Service Casualty 

Module must be identical with the entries on the corresponding Basic Module. If injuries occur in an 

exposure fire, the casualty report should have the same entries as those from Section A of the Basic Module 

for that exposure fire. An example of a completed Section A can be found on page 3–8.

CHAPTER 8 • EMS MODULE (NFIRS-6)

The P denotes a required field.

CHAPTER 8 • EMS MODULE (NFIRS–6)

The EMS Module is an optional module. It should be used when that option has been chosen by your State or local authorities.

This module is completed only if the fire department provides emergency medical service. If an independent provider performs EMS, do not use this module.

The purpose of the EMS Module is to gather basic data as it relates to the provision of emergency medical 

care to the community. It may be used by both responding EMS unit(s) and responding fire suppression 

unit(s) that provide emergency medical services. This module does not include patient care information. 

The data collected from this form are incident based not patient based.

The EMS Module is not intended to replace or otherwise interfere with State or local EMS patient care 

reporting requirements. Instead, it is the intent that the data elements contained in this module be viewed 

as “core elements” and be included in the design of upgrades or new EMS data collection systems.

The EMS Module may be completed when an Incident Type 100–243, 311, 321-323, 351–381, 400–431, 

451, or 900 is reported in Section C of the Basic Module (NFIRS–1).

If the EMS is a fire casualty, completion of a separate Fire Service Casualty Module (NFIRS–5) is required.

SECTION A

The guidance and directions for completing Section A of the EMS Module are the same as for Section A in 

the Basic Module. It is stressed that the entries in Section A of the EMS Module must be identical with the 

entries on the corresponding Basic Module. An example of a completed Section A can be found on page 

3–8.

A of the Basic Module for that exposure.

Delete/Change

Definition

Indicates a change to information submitted on a previous EMS Module or a deletion of all information 

regarding that patient.

Purpose

To delete or change previously reported information.

Entry

Delete. Check or mark this box when you have previously submitted data on this EMS patient and now want 

to have the data on this patient deleted from the database. If this box is marked, complete Section A, the 

Patient Number originally assigned (Section B), and leave the rest of the report blank. Forward the report 

according to your normally established procedures.

Change. Check or mark this box only if you previously submitted this fire incident to your State reporting 

authority and now want to update or change the information in the State database. Complete Section A and 

any other sections or blocks that need to be updated or corrected. If you need to blank a field that contains 

data, you must resubmit the original module containing the newly blanked field along with all the other 

original information in the module for that incident. This action is required only when sending an updated 

module to your State reporting authority. Forward the report according to your normally established procedures.

Definitions

Time arrived at patient. The time when the fire department’s emergency personnel established direct contact 

with the patient.

Time of patient transfer. The time when the response unit physically left the scene to transport the patient to an 

emergency care facility or the time when the patient was transferred to another care provider.

Purpose

This information is needed to analyze time spent providing patient care on the scene of an incident. If 

the Apparatus/Personnel Module (NFIRS–9/–10) is also used, then this element can document situations 

when there is a significant delay between the time the response unit arrives on the scene and the time at 

which personnel can access the patient.

Entry

For each incident, enter the dates (mm/dd/yyyy) and times of day (using the 24-hour clock) when 

emergency personnel arrived at the patient and when the patient was transferred to another care provider. 

Midnight is 0000 and signifies the start of a new day.

If the date(s) is the same as the Alarm date (Block E1, Basic Module), check the box(es) and enter only 

the time of day.

CHAPTER 9 • HAZMAT MODULE (NFIRS-7)

The P denotes a required field.

CHAPTER 9 • HAZARDOUS MATERIALS MODULE 

(NFIRS–7)

The Hazardous Materials (HazMat) Module is an optional module. It should be used when that option has been chosen by your State or local authorities.

The HazMat Module is used when the Other box in Block H3 (“Hazardous Materials Release”) of the Basic 

Module (NFIRS–1) has been checked. Its purpose is to document reportable HazMat incidents. Generally 

speaking, a reportable HazMat incident is when either:

1. Specialized HazMat resources were dispatched or used, or should have been dispatched 

or used, for assessing, mitigating, or managing the situation.

OR

2. Releases or spills of hazardous materials that exceed 55 gallons occur.

Nothing in this definition is meant to alter compliance with State or local HazMat reporting requirements. 

In States with mandatory reporting, the State reporting authority determines which optional modules 

(EMS, HazMat, Wildland, etc.) are to be submitted to the State.

The HazMat Module permits hazardous materials incidents to be thoroughly profiled for incident management analysis and response strategy development. It collects relevant information on:

•	 Hazardous materials identification.

•	 Container information.

•	 Release amounts and location.

•	 Actions taken.

•	 Mitigating factors.

In addition, aggregated data on hazardous materials incidents will provide invaluable information that 

can be used by policymakers who develop regulations for the storage, use, and transportation of hazardous materials. It can also be used to develop recommended guidance for emergency personnel response to 

HazMat incidents.

If more than one HazMat was involved, one form is completed for each HazMat released. (The term 

release is intended to include spill.)

SECTION A

The guidance and directions for completing Section A of the HazMat Module are essentially the same as 

for Section A in the Basic Module. One additional field is included in Section A of the HazMat Module (Haz 

No.). It is stressed that the entries in Section A of the HazMat Module must be identical with the entries on 

the corresponding Basic Module. An example of a completed Section A can be found on page 3–8.

Identification of specific hazardous materials involved in fire or rescue incidents is a priority for emergency 

response personnel.

UN Number

Definition

A four-digit number assigned to the hazardous material that conforms to United Nations (UN) standards 

for the identification of hazardous materials in international transportation. In some cases, a single UN 

number will be assigned to several materials with similar properties. Not all hazardous materials have been 

assigned a UN number.

Purpose

Aggregate information on the identities of hazardous materials being released can reveal trends or patterns 

for particular materials or classes of materials. These trends may provide direction for policymakers, prevention efforts, and training curricula.

Entry

Enter the four-digit UN number assigned to the hazardous material. Leave the entry blank if a UN number 

has not been assigned.

These numbers may be found in a variety of reference materials, including USFA’s Hazardous Materials Guide

DOT Hazard Classification

Definition

The Department of Transportation hazard classification describes the primary hazard associated with various categories of hazardous materials. The DOT hazard classification is intended for use on placards or 

labels during the transportation of hazardous materials. Since many materials have multiple hazards, these 

placards or labels may not describe all of the potential hazards faced by emergency responders at a HazMat 

incident.

Purpose

Aggregate information on the identities of hazardous materials being released can reveal trends or patterns 

for particular materials or classes of materials. These trends may provide direction for policymakers, 

prevention efforts, and training curricula.

Definition

The piece of equipment that either malfunctioned or, while working properly, allowed the release or 

threatened release of hazardous materials.

Purpose

Analysis of the equipment involved in a HazMat release is useful for improving product safety and preventive 

maintenance. It is just as important to know the kind of equipment that was used improperly as it is to know 

the kind of equipment that malfunctioned. Misuse can be the direct result of the way the equipment is designed 

and constructed. When involved in release, equipment information provides an important part of the causal data.

SECTION P

P HazMat Civilian Casualties

Definition

The number of civilians injured or killed, either as a result of a HazMat incident or the action of handling 

the HazMat incident. The term injury refers to physical damage to a person that requires either:

Treatment within 1 year of the incident by a practitioner of medicine,

OR

At least 1 day of restricted activity immediately following the incident. An injured person is a casualty.

Purpose

The collection of information on the number of persons injured or killed as a result of their contact or exposure to hazardous materials that have been spilled or released can provide a concise measure of the scope 

of the human cost associated with hazardous materials incidents. This information can also be correlated 

with container types, transport conditions, actions taken, and other data to help understand how to reduce 

future HazMat injuries.

Entry

Identify and record separately the number of civilians injured and the number of civilians killed as a result 

of a HazMat incident.

The optional EMS Module may be completed for all non-fire service persons injured or killed as a result 

of their contact or exposure to hazardous materials. The Civilian Fire Casualty Module should not be 

used for this purpose unless the release resulted in a fire and the civilians were injured as a result of 

the fire. The Fire Service Casualty Module should be completed for all fire service personnel injured or 

killed as a result of their contact or exposure to hazardous materials.

HazMat civilian casualties should not be entered in Block H1 of the Basic Module.

Example

One hundred civilians had varying degrees of nausea and dizziness as a result of the HazMat release:

CHAPTER 10 

WILDLAND FIRE MODULE (NFIRS–8)

Historically, NFIRS data have not proven useful in understanding the nature and magnitude of the wildland fire problem. The optional Wildland Fire Module, in conjunction with the Basic Module and other optional modules, attempts to rectify this problem by capturing data about the number of acres burned, 

the type of materials involved, the conditions that contributed to the ignition and spread of wildland fires, 

and the resources needed to control or extinguish them.

The purpose of the Wildland Fire Module is to document reportable wildland fires:

Reportable Wildland Fire: Any fire involving vegetative fuels, including a prescribed fire, that occurs in the 

wildland or urban-wildland interface areas, including those fires that threaten or consume structures.

Prescribed fires are included in this definition of reportable fires to better understand the role of fire in the 

wildland ecosystem.

In accordance with your State or local policy, the Wildland Fire Module may be used in place of the Fire

SECTION G

G Equipment Involved in Ignition

Definition

The piece of equipment that provided the principal heat source to cause the ignition if the equipment malfunctioned or was used improperly.

Purpose

Analysis of the equipment involved in ignition is useful for improving product safety and preventive maintenance. It is just as important to know the kind of equipment that was used improperly as it is to know 

the kind of equipment that malfunctioned. Misuse can be the direct result of the way the equipment is 

designed and constructed. When involved in ignition, equipment information provides an important part 

of the causal data. Equipment involved in ignition can be compared to other casual data to determine if the 

equipment was (or was not) operating properly.

Entry

Enter the three-digit code and description that best describes the equipment involved in ignition. If no 

equipment was involved in ignition, check or mark the None box.

SECTION H

H Weather Information

Descriptive information regarding weather conditions that existed at the time and location of the fire origin helps identify conditions that may have contributed to the fire cause or spread.

NFDRS Weather Station ID

Definition

Space is provided to record the six-character identification number for the National Fire Danger Rating 

System (NFDRS) Weather Station that monitors weather conditions at the location of fire origin.

Purpose

Researchers can obtain specific weather data for the time and location of the fire origin. Specific weather 

data permits analysis of those conditions that may have contributed to the fire cause or spread.

Entry

Enter the six-digit NFDRS Weather Station ID number. See the completed example at the end of Section H.

If the descriptive weather information is not provided, it will be necessary for the local fire department 

to access the NFDRS database to perform later analysis of wildland fires using weather data. Because this 

may not always be feasible, fire departments should always complete this section themselves whenever 

possible.

Entry

Enter the average wind speed, to the nearest mile per hour, at the origin of the fire. Wind speed may be 

measured using an anemometer. Calm conditions are recorded as “0.” See the completed example at the 

end of Section H.

Temperature and Relative Humidity

Definitions

Air temperature is measured in degrees Fahrenheit at the location of the fire origin when the fire started. 

Relative humidity is the ratio expressed as a percent of the amount of water vapor to the greatest amount 

possible at the same temperature.

Purpose

Temperature and humidity information is used to access the potential for ignition in various weather 

conditions and to understand problems associated with suppressing fires in different ambient temperatures 

and humidity levels.

Entries

Enter the actual or estimated air temperature in degrees Fahrenheit at the time the incident started. If the 

temperature is below zero, check or mark the box that indicates a negative temperature.

Enter the percent humidity at the time the incident started. See the completed example at the end of Section H.

Fuel Moisture

Definition

The 10-hour reading of the moisture content of a fuel stick taken in the general area of fire origin. Fuel 

moisture is expressed as a percentage of the weight (generally ranging from 0 to 25 percent).

Purpose

Information about fuel moisture is used in fire modeling to assess the potential for ignition and rate of 

spread for different fuels under various weather conditions.

Entry

Enter the fuel moisture percentage level. See the completed example at the end of Section H.

Fire Danger Rating

Definition

Fire danger rating refers to one method of describing the wildfire threat in a particular area, based on the 

NFDRS. It is derived from both constant and variable fire danger factors that affect the ignition, spread, and 

difficulty of control of fires and the damage they cause. Factors considered when estimating the fire danger 

are temperature, relative humidity, wind speed, fuel type, and fuel moisture.

Purpose

This information is used in fire prevention activities to determine when fires are most likely to occur and 

their severity. Burning bans and park or forest closures or restrictions may be invoked based on the fire 

danger rating. It is also useful in pre-suppression planning to determine staffing levels and critical initial 

attack times.

Recording the estimated number of acres burned indicates the magnitude of each fire and of the wildland 

fire problem overall. This can be used to evaluate progress in wildland fire prevention. This information 

can also help determine the magnitude of resources that should be devoted to fire protection and the cost 

effectiveness of various programs. An estimate of the number of acres burned represents a vital component 

of the overall fire loss picture.

Entry

Enter the total number of acres burned. If less than one acre was burned, the decimal point field should be 

used to denote tenths of an acre.

This entry should be the most accurate estimate of acres burned that is practical to obtain (one acre 

equals 43,560 square feet). Estimates based on the use of accurately scaled maps, dot grids, planimeters, or other accurate measuring methods are preferred.

Example

A fire destroys 1,671 acres:

Primary Crops Burned

Definition

This data element identifies up to three types of crops that burned.

Purpose

Information about what type of crops burned is useful as a measure of loss and in tracking trends and patterns in wildland fires as well as planning prevention strategies.

Entry

Enter up to three primary crops that burned in the fire. Enter the crop with the most burned acres first. If 

no crops were burned, leave this block blank.

SECTION J

Property Management

Definition

The name of the principle entity having responsibility for the maintenance or control of the property 

where the fire originated. It also allows for the reporting of the percent of the total acres burned for each 

type of ownership involved.

Purpose

The number of acres burned by property ownership is of significant value to local fire departments as well 

as to State and Federal wildland agencies. It provides a means to determine the frequency and impact of 

fire on property managers, especially major holders of land, such as ranchers, lumber and paper companies, agricultural producers, and Federal and State governments. This information also can help target fire 

protection programs at entities having the greatest risk or loss potential.

Entry

Indicate the percent of the total acres burned for each type of ownership involved, then check or mark the 

box that best describes the principle entity responsible for the property where the fire originated. If responsibility cannot be determined or is unknown, check or mark the Undetermined box.

Check or mark only one owner/management entity.

If the Federal (6) box was checked or marked, enter the Federal Agency Code.

K NFDRS Fuel Model at Origin

Definition

This data element identifies the type of wildland fuel involved in a wildland fire at the point of origin. The 

Fuel Model is a simulated fuel complex or description of various vegetative fuels and combinations of vegetative fuels. Fuel models were devised as a means of organizing information about vegetative fuels for use 

in the National Fire Danger Rating System (NFDRS) to predict fire danger. The local forester should be able 

to assist in identifying the fuel models in your area.

Purpose 

Fuel models were devised as a means for organizing the required wildland fuels information that is used in 

the NFDRS to predict the behavior of a potential wildfire.

Entry

Enter the two-digit NFDRS Fuel Model code and description that best identifies the type of wildland 

vegetation burned at the point of origin.

Example

The fire area consisted of mostly mature brush (02):NFDRS FUEL MODEL AT ORIGIN CODES

K NFDRS Fuel Model at Origin

Enter the code and the descriptor corresponding

to the NFDRS Fuel Model at Origin

0 2 Mature brush

NFDRS FUEL MODEL AT ORIGIN CODES

01 Fuel Model A—Annual grasses. This fuel model represents grasslands vegetated by annual grasses and forbs. Brush 

or trees may be present but are very sparse, occupying less than one-third of the area. Examples of types where 

Fuel Model A should be used are cheatgrass and medusahead. Open pinyon-juniper, sagebrush-grass, and desert 

shrub association may appropriately be assigned this fuel model if the woody plants meet the density criteria. 

The quantity and continuity of the ground fuels vary greatly with rainfall from year-to-year.

02 Fuel Model B—Mature brush (6 feet or higher). Mature, dense fields of brush 6 feet (2 m) or more in height are 

represented by this fuel model. One-fourth or more of the aerial fuel in such stands is dead. Foliage burns readily. 

Model B fuels are potentially very dangerous, fostering intense, fast-spreading fires. This model is for California 

mixed chaparral generally 30 years or older. The B model is more appropriate for pure chamise stands. The B 

model may also be used for the New Jersey pine barrens.
10-51 NFIRS 5.0 COMPLETE REFERENCE GUIDE

CHAPTER 10 • WILDLAND FIRE MODULE (NFIRS-8)

The P denotes a required field.

K

03 Fuel Model C—Open pine with grass. Open pine stands typify Model C fuels. Perennial grasses and forbs are the 

primary ground fuel, but there is enough needle litter and branchwood present to contribute significantly to the 

fuel loading. Some brush and shrubs may be present, but they are of little consequence. Situations covered by 

Fuel Model C are open, longleaf, slash, ponderosa, jeffrey, and sugar pine stands. Some pinyon-juniper stands may 

qualify.

04 Fuel Model D—Southern rough. This fuel model is specifically for the palmetto-gallberry understory–pine overstory association of the southeast coastal plains. It can also be used for the so-called “low pocosins” where Fuel 

Model O might be too severe. This model should only be used in the Southeast because of a high moisture of 

extinction.

05 Fuel Model E—Hardwood litter (fall). Use this model after leaf fall for hardwood and mixed hardwood–conifer 

types where the hardwoods dominate. The fuel is primarily hardwood leaf litter. The oak–hickory types are best 

represented by Fuel Model E, but E is an acceptable choice for northern hardwoods and mixed forests of the 

Southeast. In high winds, the fire danger may be underrated because rolling and blowing leaves are not taken into 

account. In the summer after the trees have leafed out, Fuel Model E should be replaced by Fuel Model R.

06 Fuel Model F—Intermountain West brush. Model F represents mature closed chamise stands and oakbrush fields 

of Arizona, Utah, and Colorado. It also applies to young, closed stands and mature, open stands of California 

mixed chaparral. Open stands of pinyon-juniper are represented; however, fire activity will be overrated when 

windspeeds are low and where ground fuels are sparse.

07 Fuel Model G—West Coast conifers; close, heavy down materials. Fuel Model G is used for dense conifer stands 

where there is a heavy accumulation of litter and downed woody material. Such stands are typically overmature 

and may also be suffering insect, disease, wind, or ice damage—natural events that create a very heavy buildup 

of dead material on the forest floor. The duff and litter are deep, and much of the woody material is more than 3 

in (7.5 cm) in diameter. The undergrowth is variable, but shrubs are usually restricted to openings. Types meant 

to be represented by Fuel Model G are hemlock–Sitka spruce, coast douglas fir, and wind-thrown or bug-killed 

stands of lodgepole pine and spruce.

08 Fuel Model H—Short-needle conifers; normal down woody materials. The short-needled conifers (white pines, 

spruces, larches, and firs) are represented by Fuel Model H. In contrast to Model G fuels, Fuel Model H describes 

a healthy stand with sparse undergrowth and a thin layer of ground fuels. Fires in H fuels are typically slow 

spreading and are dangerous only in scattered areas where the downed woody material is concentrated.

09 Fuel Model I— Heavy slash, clear-cut conifers greater than 25 tons per acre. Fuel Model I was designed for 

clearcut conifer slash where the total loading of materials less than 6 in (15 cm) in diameter exceeds 25 tons per 

acre. After settling and the fines (needles and twigs) fall from the branches, Fuel Model I will overrate the fire 

potential. For lighter loadings of clearcut conifer slash, Fuel Model J should be used, and for light thinnings and 

partial cuts where the slash is scattered under a residual overstory, Fuel Model K should be used.

10 Fuel Model J—Medium slash, heavily thinned conifers (less than 25 tons per acre). This model complements 

Fuel Model I. It is for clearcuts and heavily thinned conifer stands where the total loading of materials less than 6 

in (15 cm) in diameter is less than 25 tons per acre. Again, as the slash ages, the fire potential will be overrated.

11 Fuel Model K—Light slash (less than 15 tons per acre). Slash fuels from light thinnings and partial cuts in conifer 

stands are represented by Fuel Model K. Typically, the slash is scattered about under an open overstory. This model 

applies to hardwood slash and to southern pine clearcuts where the loading of all fuels is less than 15 tons per 

acre.

12 Fuel Model L—Perennial grasses. This fuel model is meant to represent grasslands vegetated by perennial grasses. 

The principal species are coarser and the loading heavier than those in Model A fuels. Otherwise the situations 

are very similar; shrubs and trees occupy less than one-third of the area. The quantity of fuel in these areas is 

more stable from year-to-year. In sagebrush areas, Fuel Model T may be more appropriate.

CHAPTER 10 • WILDLAND FIRE MODULE (NFIRS-8)

The P denotes a required field.

K

14 Fuel Model N—Sawgrass, marsh needle-like grass. This fuel model was constructed specifically for the 

sawgrass prairies of south Florida. It may be useful in other marsh situations where the fuel is coarse 

and reedlike. The model assumes that one-third of the aerial portion of the plants is dead. Fast-spreading, 

intense fires can occur even over standing water.

15 Fuel Model O—High pocosin. Fuel Model O applies to dense, brushlike fuels of the Southeast. O fuels, except for a 

deep litter layer, are almost entirely living, in contrast to B fuels. The foliage burns readily except during the active 

growing season. The plants are typically over 6 ft (2 m) tall and are often found under an open stand of pine. The 

high pocosins of the Virginia, North Carolina, and South Carolina coasts are the ideal of Fuel Model O. If the plants 

do not meet the 6-ft (2-m) criteria in those areas, Fuel Model D should be used.

16 Fuel Model P—Southern long-needle pine. Closed, thrifty stands of long-needled southern pines are characteristic of P fuels. A 2- to 4-in (5- to 10-cm) layer of lightly compacted needle litter is the primary fuel. Some smalldiameter branchwood is present, but the density of the canopy precludes more than a scattering of shrubs and 

grass. Fuel Model P has the high moisture of extinction characteristic of the Southeast. The corresponding model 

for other long-needled pines is U.

17 Fuel Model Q—Alaska black spruce. Upland Alaskan black spruce is represented by Fuel Model Q. The stands are 

dense but have frequent openings filled with usually flammable shrub species. The forest floor is a deep layer of 

moss and lichens, but there is some needle litter and small-diameter branchwood. The branches persist on the trees, 

and ground fires easily reach into the tree crowns. This fuel model may be useful for jack pine stands in the Lake 

States. Ground fires are typically slow spreading, but a dangerous crowning potential exists.

18 Fuel Model R—Hardwood litter (summer). This fuel model represents the hardwood areas after the canopies leaf 

out in the spring. It is provided as the off-season substitute for Fuel Model F. It should be used during the summer 

in all hardwood and mixed conifer–hardwood stands where more than half of the overstory is deciduous.

19 Fuel Model S—Tundra. Alaskan or alpine tundra on relatively well-drained sites is the S fuel. Grass and low shrubs 

are often present, but the principal fuel is a deep layer of lichens and moss. Fires in these fuels are not fast spreading or intense, but are difficult to extinguish.

20 Fuel Model T—Sagebrush with grass. The bothersome sagebrush-grass types of the Great Basin and the Intermountain West are characteristic of T fuels. The shrubs burn easily and are not dense enough to shade out grass and 

other herbaceous plants. The shrubs must occupy at least one-third of the site, or the A or L fuel models should be 

used. Fuel Model I might be used for immature scrub oak and desert shrub associations in the West and the scrub 

oak–wire grass type in the Southeast.

21 Fuel Model U—Western long-needled pine. Closed stands of western long-needled pines are covered by this 

model. The ground fuels are primarily litter and small branchwood. Grass and shrubs are precluded by the dense 

canopy, but occur in the occasional natural opening. Fuel Model U should be used for ponderosa, Jeffrey, sugar, and 

red pine stands of the Lake States. Fuel Model P is the corresponding model for southern pine plantations.

UU Undetermined.

Usually, the Clear time represents when the apparatus or resources are cleared from the scene. In the 

case of transport of a casualty, however, the Clear time is when the apparatus completes the transport 

and is available for new duty.

Purpose

The time when the resources or apparatus are cleared is valuable to fire department management because 

it reflects the time spent stabilizing the incident. This assists in determining service demand and costs for 

resource allocation.

Usually, the Clear time represents when the apparatus or resources are cleared from the scene. In the 

case of transport of a casualty, however, the Clear time is when the apparatus completes the transport 

and is available for new duty.

Purpose

The time when the resources or apparatus are cleared is valuable to fire department management because 

it reflects the time spent stabilizing the incident. This assists in determining service demand and costs for 

resource allocation.

CHAPTER 13 

ARSON MODULE (NFIRS–11)

An indispensable tool in the war against arson is the ability to identify with precision when and where the 

crime takes place, what form it takes, and the characteristics of its targets and perpetrators. Armed with 

such information, fire service and law enforcement agencies can develop and implement arson prevention 

initiatives that will allow them to use their resources in the most efficient and effective manner. The NFIRS 

5.0 Arson Module (NFIRS–11) was developed with this goal in mind.

Arson: To unlawfully and intentionally damage, or attempt to damage, any real or personal property by 

fire or incendiary device.

This optional Arson Module may be used whenever the Cause of Ignition (Fire Module, Block E1) is coded 

as Intentional or as Cause Under Investigation without any distinction made as to whether a crime has 

occurred or a determination of criminal intent. The Arson Module may also be used when the fire is coded 

as Cause Undetermined After Investigation.

The Arson Module may also be used to document juvenile-set fires, whether determined to be intentional, 

unintentional, or under investigation. This information will permit analysis of juvenile firesetting trends, 

including intervention strategies and recidivism.

Juvenile-set fires are defined to be those fires where the person involved in the ignition is under the age 

of 18.

The Arson Module consists of two parts: a local investigation module that permits a fire department or 

arson investigation unit to document certain details concerning the incident; and a juvenile firesetter section that identifies key items of information that could be used for local, State, and national intervention 

programs.

Many arson investigation units use an arson information management system to collect and compile information on arson incidents. This module is not intended to replace such systems; instead, it identifies those 

data elements that could be exported to NFIRS and included as an integral part of the U.S. Fire Administration National Fire Database and the Bureau of Alcohol, Tobacco and Firearms (BATF), Arson and Explosives 

National Repository.

SECTION A

The guidance and directions for completing Section A of the Arson Module are the same as for Section A in 

the Basic Module. It is stressed that the entries in Section A of the Arson Module must be identical with the 

entries on the corresponding Basic Module. An example of a completed Section A can be found on page 

3–8.

original information in the module for that incident. This action is required only when sending an updated 

module to your State reporting authority. Forward the report according to your normally established procedures.

SECTION B

B Agency Referred To

Definition

Identifies the agency, if any, the incident was referred to for follow-up investigation. This might be a law 

enforcement agency that has jurisdiction for a criminal investigation or another fire department that may 

have been requested to conduct the investigation.

Purpose

This element provides the details necessary to contact the agency that conducted any follow-up of the 

incident. It also allows for the collection, compilation, and analysis of all data associated with a specific 

incident.

Entry

Enter the referred agency’s name, telephone number, address, case number, Originating Agency Identifier 

(ORI) number, Federal Identifier (FID) code, and FDID (if applicable). Check or mark the None box if the 

case was not referred to another agency.

ORI: A unique identification number assigned to law enforcement agencies (towns, cities, counties, State 

police agencies, and some colleges and universities) participating in the FBI’s Uniform Crime Reporting 

(UCR) system or the National Incident-Based Reporting System (NIBRS).

FID: A two-character identification number used by Federal departments to submit crime data to UCR/

NIBRS gathered by its dependent bureau/agencies. 

Collectively, the ORI, FID, and Incident numbers provide the necessary uniqueness to avoid duplication of 

reported incidents.

“00” is used for State and local agencies as the FID codes. Federal departments such as the FBI use an 

assigned FID code. This list is not provided in this guide.

Also enter the complete address of the agency the incident was referred to for follow-up investigation.

Supplemental Special Studies

Definition

These fields should be used when you are using the paper forms and need space for more than one special 

study.

Temporary data elements that can be used for collection of information that is of special interest for a 

defined period. Special studies are typically required to capture information on emerging trends, problem 

areas, or a specific issue being studied. When the answer becomes known through the special study, the 

collection of that field is no longer required. If the data will always be needed for permanent collection, a 

State- or department-defined permanent user field should be created and used instead of the Special Studies field. A State, a fire department, or the NFDC can define special studies.

Special Study ID Number: This number uniquely identifies each special study that is being run by the fire 

department, State, or NFDC

Special Study Value: The value in the field being collected. Responses for special studies can be defined as 

codes or as alphanumeric entries of numeric values or dates. States, fire departments, and the NFDC can 

define Special Studies fields.

Purpose

The use of special studies allows departments, States, and the NFDC to quickly collect information on an 

issue or problem and answer a specific question through the temporary use of a special study field over a 

defined period of time. This is a State or local option.

Entry

If you are participating in a Special Study, your entry will depend on the type of data being collected. Use 

the codeset defined for the particular Special Study field if it is a coded entry. The data entered may also be 

a date or a numeric entry if the field has been so defined.

Appendix C 

Glossary of Terms and Abbreviations

Terms

The terminology used in this document provides a common language for recording fire service data. The 

following terms are used as defined and discussed below.

Alarm. Any notification made to the fire department that a situation exists or may exist that requires a 

response.

Area of Origin. The use of the room or area within the property where the fire originated.

Automatic. As applied to fire protection devices, a device or system providing an emergency function 

without the necessity of human intervention.

Backfire. A fire set along the inner edge of a fire control line to consume the fuel in the path of a 

wildland fire or change the direction of force of the fire’s convection column. Doing this on a 

small scale and with closer control, in order to consume patches of unburned fuel and aid control line construction, is known as “burning out.”

Building. A structure enclosed with walls and a roof and having a defined height.

Building Fire. See Structure Fire.

Burning. The process of self-perpetuating combustion, with or without an open flame. Smoldering 

is burning.

Casualty (Fire). A person who is injured or killed at the scene of a fire. (Includes injuries or deaths 

from natural or accidental causes sustained while involved in the activities of fire control, rescue 

attempt, or escaping from the dangers of the fire.)

Census Data. Demographic population data available by statistical areas from a governmental agency.

Civilian Fire Casualty. Any non-fire service casualty who is injured or killed at the scene of a fire.

Char. Material that has been partially burned on the exterior of the object and has a blackened carbonized appearance.

Combustible. A material or structure that will release heat energy on burning.

Combustible Liquid. Any liquid having a flash point at or above 100°F (37.8°C) (closed cup).
C-3 NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

The P denotes a required field.

Confine a Fire. To restrict the fire within determined boundaries established either prior to the fire 

or during the fire. Wildland suppression action may be minimal and limited to surveillance under appropriate conditions.

Contain a Fire. To take suppression action as needed that can reasonably be expected to check the 

fire’s spread under prevailing conditions.

Emergency Scene. The area encompassed by the incident and the surrounding area needed by the 

emergency forces to stage apparatus and mitigate the incident.

EMT–Basic. Technician has the knowledge and skills of the first responder, but is also qualified to 

function as minimum staff for an ambulance (see Table of Care). For example, at the scene of a 

cardiac arrest, the EMT–Basic would be expected to defibrillate and ventilate the patient with a 

manually operated device and supplemental oxygen.

EMT–Intermediate. Technician has the knowledge and skills of the preceding levels, but also can 

perform essential advanced techniques and administer a limited number of medications (see 

Table of Care). For example, at the scene of a cardiac arrest, the EMT–Intermediate would be 

expected to intubate and administer first-line ACLS medications.

EMT–Paramedic. Technician has demonstrated the competencies expected of an EMT–Intermediate 

provider, but also can administer additional interventions and medications (see Table of Care). 

For example, at the scene of a cardiac arrest, the EMT–Paramedic might administer second-line 

ACLS medications and use an external pacemaker.

Explosion. Violent bursting caused by either a combustion process or an overpressure condition. 

Typical combustion processes include ignition and burning of combustible gas, dust, or flammable vapor mixture. These are technically “fires.” Typical overpressure conditions include steam 

pressure, chemical reactions, and compressed gas container rupture. These are technically not 

“fires.”

Exposure Fire. A fire in a building, structure, vehicle, or outside property resulting from a fire 

outside that building, structure, vehicle, or outside property.

Exposure (Human). Potential for injury or death to humans.

Fatality. An injury that is fatal or becomes fatal within 1 year of the incident.

Fire. Any instance of destructive and uncontrolled burning, including explosion, of combustible 

solids, liquids, or gases. Fire does not include the following, except where they cause fire or 

occur as a consequence of fire:

	 • Lightning or electrical discharge.

	 • Rupture of a steam boiler, hot water tank, or other pressure vessel due to internal pressure and

 not to internal combustion.

	 • Explosion of munitions or other detonating material.
C-4 NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

The P denotes a required field.

	 • Accident involving ship, aircraft, or other vehicle.

	 • Overheat condition.

Fire Area (Structure). The space within a structure bounded by fire division assemblies 

 (2-hour fire rating or greater).

Fire Area (Wildland). The area within wildfire perimeter control lines.

Fire Blackout. That point in time when there is no longer any evidence of open flame or glow of

 burned material.

Fire Contained. That point in time when fire spread is stopped, but the fire is not necessarily under 

control.

Fire Control Line. Comprehensive term for all constructed or natural barriers and treated fire edges 

used to control a fire.

Fire Damage. The total damage to a building, structure, vehicle, natural vegetation cover, or outside 

property resulting from a fire and the act of controlling that fire. Included are smoke, water, 

backfires, firebreaks, and fire control damage.

Fire Extinguished. That point in time when there is no longer any abnormal heat or smoke being 

generated in material that was previously burning.

Fire Ground. See Emergency Scene.

Fire Service Personnel. All employees, whether career or volunteer, of a fire department who are 

assigned or may be assigned to perform duties at emergency incidents.

Fire Under Control. (1) That point in time when a fire is sufficiently surrounded and quenched so 

that in the judgment of the commanding officer it no longer threatens destruction of additional 

property. (2) In wildfire, that point in time when a control line is around a fire, any spot fires 

therefrom, and any interior islands to be saved. Any unburned area adjacent to the fire side of the 

control lines are burned out, and all hot spots that are immediate threats to the control line are 

cooled down, until the lines can reasonably be expected to hold under foreseeable conditions.

First Responder. Uses a limited amount of equipment with various knowledge and skill in each of 

the core elements (see EMS levels above). For example, at the scene of a cardiac arrest, the first 

responder would be expected to notify EMS (if not already notified) and initiate CPR with an 

oral airway and a barrier device.

Fixed Object. An object, device, or appliance that is fastened or secured at a specific location (e.g., a 

steam radiator).

Flames. Products of combustion that are illuminated by the heat of combustion and accompany the 

burning of most materials in normal atmospheres.
C-5 NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

The P denotes a required field.

Flammable Liquid. Any liquid having a flash point below 100°F (37.8°C) (closed cup) and having a 

vapor pressure not exceeding 40 psia (2068 mm Hg) at 100°F (37.8°C).

Gas. A material that has a vapor pressure exceeding 40 psia (2068.6 mm) at 100°F (37.8°C). (Gasoline is a liquid, not a gas.)

General Property Use. The actual general (overall) use of land or space under the same management or ownership or within the same legal boundaries, including any structures, vehicles, or 

other appurtenances thereon.

Grade. Reference plane representing the elevation of finished ground level adjoining the building at 

the main entrance.

Hazardous Material. Any material that is an air-reactive material, flammable or combustible liquid, flammable gas, corrosive material, explosive material, organic peroxide, oxidizing material, 

radioactive material, toxic material, unstable material, or water-reactive material; and any substance or mixture of substances that is an irritant or a strong sensitizer or that generates pressure 

through exposure to heat, decomposition, or other means.

Heat of Ignition. The heat energy that brings about ignition. Heat energy comes in various forms 

and usually from a specific object or source. Therefore, the heat of ignition is divided into two 

parts: “equipment involved in ignition” and “form of heat of ignition.”

Ignition. The physical and chemical processes involved in reaching a point of self-perpetuation of 

fire whether or not there is an open flame.

Ignition Factor. The condition or situation that allowed a heat source and a combustible material to 

combine to initiate a fire. 

Incident. An event to which the reporting agency responds or should have responded. Included are 

“walk-ins” treated at the station. An incident may have more than one response. A rekindle is a 

separate incident.

Incident Record. The official file on an incident.

Incident Report. A document prepared by fire department personnel about a particular incident. 

For understanding and legal purposes, this report should be in their own words. For summarization purposes, the information on this report can be classified into broad categories. The incident 

report is always part of the incident record or file.

Injury. Physical damage to a person suffered as the result of an incident that requires (or should 

require) treatment by a practitioner of medicine, a registered EMT, or a paramedic within 1 year 

of the incident (regardless of whether treatment was actually received) or that results in at least 1 

day of restricted activity immediately following the incident.

APPENDIX C• GLOSSARY

The P denotes a required field.

Latitude. Latitude lines run east/west parallel to the equator. Values range from 0 degrees at the equator to 90 degrees at the North and South poles. The United States and Canada are in the Northern 

Hemisphere. Minutes and seconds range from 0 to 59.

Longitude. Longitude lines run north/south, are parallel at the equator, and converge at the North 

and South Poles. Values ranges from 0 degrees at Greenwich, England (near London at the Royal 

Naval Observatory) to 180 degrees at the International Date Line west of Hawaii. Most of the 

United States and all of Canada are in the Western Hemisphere. Minutes and seconds range from 

0 to 59.

Liquid. A material that has a vapor pressure not exceeding 40 psia (2068.6 mm) at 100°F (37.8°C).

Material First Ignited. The combustible that is first set on fire by the heat of ignition.

Mobile Property Type. Property that was designed to be movable whether or not it still is (e.g., 

vehicles, ships, and airplanes). 

Mop-Up. The act of making a fire scene safer after the fire has been controlled, such as extinguishing 

or removing burning material along or near the control line, felling snags, and trenching logs to 

prevent rolling. For structure fires, see Overhaul.

Non-Fire Service Personnel. All persons involved with an incident who are not fire service personnel. Included are police, utility company employees, non-fire service medical personnel, and 

civilians.

Not Occupied. An area with no persons present; contents or equipment present indicates the structure is not vacant.

Occupancy. The purpose for which a building or portion thereof is intended to be used. The specific 

property use as it pertains to a building is the occupancy.

Occupied. An area with persons present. A hotel (general property use) could be occupied, but the 

restaurant (specific property use) not occupied; likewise, the restaurant could be occupied, but 

its storeroom (area of origin) not occupied.

Overhaul. The act of making a fire scene safe after it is controlled, such as extinguishing or removing 

burned material, checking inside walls and hidden spaces, etc. For wildland fires, see Mop-Up.

Overheat. Destruction of material by heat without self-sustained combustion. Removal of the heat 

source will stop the destruction. Overheat is the stage before ignition.

Overpressure. A transient air pressure, such as the shock wave from an explosion, that is greater than 

the surrounding atmospheric pressure.

Portable. An object, device, or appliance that can normally be moved by one person, is designed to 

be used in multiple locations, and requires no tools to install.
C-7 NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

The P denotes a required field.

Prescribed Fire. Any fire ignited by management actions to meet specific objectives. A written, 

approved prescribed fire plan must exist prior to ignition. The controlled application of fire 

to wildland fuels in either their natural or their modified state under specified environmental 

conditions that allow the fire to be confined to a predetermined area and, at the same time, to 

produce the intensity of heat and rate of spread required to attain planned resource management 

objectives.

Principal Meridian. There are 45 principal meridians defined in the United States. They are identified at the end of this appendix.

Property. A thing of value. Specific (fixed) property refers to those things that make up the Earth’s 

surface (e.g., water, land, roadways, structures, buildings). Mobile property refers to those things 

that normally move in relation to the Earth’s surface (e.g., ships, airplanes, trains, trucks, automobiles).

Property Inventory. Information known about a property before an emergency occurs. This knowledge is in two parts: that which is general in character and has to do with external features (such 

as location, water supply, and construction), and that which is specific in character relating to 

internal features (such as interior finish, vertical openings, or suppression systems).

Property Use. The use to which a property is put. A building, for example, could serve as a garage 

or a hospital or a department store. The use of property does not define any of the other important fire-related details of a property such as access, ownership, size, internal weaknesses in fire 

defense, or construction.

Public Land Survey System. The Land Ordinance of 1785 established the Public Land Survey System in the United States. The surveys cover 30 States; other survey systems are used by the founding 13 States, Kentucky, Tennessee, Maine, Vermont, West Virginia, Texas, and Hawaii.

Range. Ranges are numbered east and west of the principal meridian. The first three digits are the 

range number and the fourth digit indicates a full or partial range (0 = full, 1 = 1/4, 2 = 1/2, 

and 3 = 3/4). The fifth character (E or W) indicates direction from the principal meridian.

Rekindle. The redevelopment of a fire after it was thought to have been extinguished by the original 

fire service response. Fire service response to a rekindle should be treated as a separate incident.

Reportable Fire. Any unfriendly, hostile fire that comes to the attention of an agency keeping fire 

records. Included are fires that may be discovered in progress or discovered after extinguishment.

Response. The deployment of an emergency service resource to an incident.

Room. The space or area bounded by walls. The walls may be fire rated and impede fire spread or not 

fire rated (e.g., mesh screen), which may impede exiting of personnel.
C-8 NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

The P denotes a required field.

Scorch. Discoloring (browning or blackening) of a material, a characteristic of the overheat condition. Removal of the heat source will stop the destruction.

Section. Sections are numbered 1–36 beginning in the northeast corner for all but the very earliest 

principal meridians. Sections 1–6 are the northern most tier and are numbered east to west. Sections 7–12 are the next tier south of the first tier and are numbered west to east. The remaining 

sections follow the same pattern. Each section is nominally 640 acres, although some sections 

vary from the standard.

Smoldering. Self-sustaining combustion of a material without any flame evident.

Stationary Object. Any object, device, or appliance that is not fastened but that is not readily moved 

from one place to another in normal use (e.g., a refrigerator).

Story. That portion of a building between the upper surface of any floor and the upper surface of the 

floor next above, except that the topmost story is that portion of a building between the upper 

surface of the topmost floor and the upper surface of the roof deck above.

Structure. An assembly of materials forming a construction for occupancy or use to serve a specific 

purpose. This includes, but is not limited to, buildings, open platforms, bridges, roof assemblies 

over open storage or process areas, tents, air-supported structures, and grandstands.

Structure Fire. Any fire inside a structure whether it involves the structure or not, or any fire under 

or touching a structure that involves the structure.

Subsection. Sections can be subdivided into successive quarters and described as the NE quarter, 

NW quarter, SE quarter, and SW quarter (each approximately 160 acres). Each quarter can be 

quartered again to describe 40-acre parcels. For example, the SE/4 of the NW/4 would be the 

40-acre parcel NW of the section center (read small parcel to large parcel).

Toxic Material. Any material that may constitute a hazard to life or health, either temporary or permanent, from exposure by contact, inhalation, or ingestion.

Township. Townships are numbered north and south of the principal base line. The first three digits 

are the township number, and the fourth digit indicates a full or partial township (0 = full, 1 = 

1/4, 2 = 1/2, and 3 = 3/4). The fifth character (N or S) indicates direction from the baseline.

Urban–Wildland Interface Area. The geographical area where structures and other human development meet or intermingle with wildland or vegetative fuels.

Urban–Wildland Interface Fire. Any fire, other than prescribed fire, where fire suppression tactics 

were influenced by a geographical area where structures and other human development meet or 

intermingle with wildland or vegetative fuels (Incident Type 632).

Vacant. No furnishings or equipment are present.
C-9 NFIRS 5.0 COMPLETE REFERENCE GUIDE

APPENDIX C• GLOSSARY

The P denotes a required field.

Wildland Fire. Any fire involving vegetative fuels, other than prescribed fire, that occurs in the wildland. A wildland fire may expose and possibly consume structures (Incident Type 141).

Wildland. Land in an uncultivated, more or less natural state and covered by timber, woodland, 

brush, or grass. An area in which development is essentially nonexistent except for roads, railroads, power lines, and similar facilities.
