Fire Behavior Field Reference Guide, PMS 437

PMS 437 Cover. Decorative.
The Fire Behavior Field Reference Guide is intended to be used in conjunction with the Fireline Handbook, Appendix B: Fire Behavior, PMS 410-2.

The FBFRG contains helpful references to the factors from the fire triangle (fuels, weather, and topography), including features that are vital to field-going fire managers. It provides detail about the fire behavior models and tools used to estimate fire ignition, spread/size, fireline intensity, and crown fire potential. The reference material will assist with decision support using various tools and methodologies.

The guide will be updated twice annually (April and November) as necessary to reflect the most recent science and technologies for field use to help improve and assist with decision support, fireline safety, and fire behavior interpretation. As new and improved safety zone research is obtained and available for distribution, the FBFRG will be updated to house that information. YouTube videos will be uploaded periodically to provide additional supporting documentation: www.youtube.com/user/FireBehaviorSC.

The Fire Behavior Field Reference Guide is developed and maintained by the Fire Behavior Subcommittee (FBSC), under the direction of the Fire Environment Committee (FENC), an entity of the National Wildfire Coordinating Group (NWCG).

While they may still contain current or useful information, previous editions are obsolete. The user of this information is responsible for confirming that they have the most up-to-date version. NWCG is the sole source for the publication.

Comments, questions, and recommendations shall be submitted to the appropriate agency representative assigned to the FBSC. View the complete roster.

The National Wildfire Coordinating Group (NWCG) provides national leadership to enable interoperable wildland fire operations among federal, state, tribal, territorial, and local partners. NWCG operations standards are interagency by design; they are developed with the intent of universal adoption by the member agencies. However, the decision to adopt and utilize them is made independently by the individual member agencies and communicated through their respective directives systems.

Updated NWCG Wildland Fire Risk and Complexity Assessment, PMS 236

Date: June 24, 2024
Contact: Incident and Position Standards Committee 

The June 2024 update of the NWCG Wildland Fire Risk and Complexity Assessment, PMS 236, is now available to meet the current needs for incident management typing.

The NWCG Wildland Fire Risk and Complexity Assessment should be used to evaluate firefighter safety issues, assess risk, and identify the appropriate incident management organization based on incident complexity. Assessing risk, determining incident complexity, and identifying an appropriate incident management organization is a subjective process based on examining a combination of indicators or factors, which can change over time.
