Fire Behavior Field Reference Guide, PMS 437
The Fire Behavior Field Reference Guide describes a range of practices by which fire behavior assessments are conducted for fireline leadership in the field, and by Fire Behavior Analysts (FBANs) and Long Term Fire Analysts (LTANs) in support of more sophisticated analysis. It is a hands-on publication for use in the field, in fire behavior training, and as a learning reference. It is intended to be used in conjunction with the Fireline Handbook, Appendix B: Fire Behavior, PMS 410-2.
The Guide 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 contained within the guide will assist with decision support using various tools and methodologies.
The guide will be updated 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, this guide will be updated to house that information. YouTube videos will be uploaded periodically to provide additional supporting documentation for information found within this guide and can be viewed at 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).
Previous editions: 2014, 2001, 1992. The 1992 edition was maintained and published through National Advanced Resources Technology Center (NARTC), currently known as the National Advanced Fire and Resource Institute (NAFRI).
