Not just what and how, but why!
Flashover is likely the most common type of extreme fire behavior encountered in structural firefighting. As my friends and colleagues from Sweden frequently observe, this is not really extreme fire behavior, its normal fire behavior. I think it is both. The term extreme “is framed within the context of our perception with ‘extreme’ defining our … Read more
In Reading the Fire: How to Improve Your Skills, I discussed building a concept map fire of behavior indicators as a method to increase competence in reading the fire. Construction of a concept map increases awareness of key indicators and understanding their interrelationships. I am working through this process along with you, with the latest … Read more
Live Fire Simulations: Key Elements of Fidelity examined some of the important elements in physical fidelity, the extent to which the simulation looks and feels real. This post will begin the process of identifying key aspects of functional fidelity, the extent to which the simulation works and reacts realistically. Maintaining the Balance One important factor … Read more
In many cases, smoke may provide the dominant indication that there is a fire in the building (but keep in mind that if you can see smoke on the exterior, there are also air track indicators). Have a look at Figure 1 and see what smoke indicators you observe. Figure 1. Smoke Indicators Note: Terry … Read more
Several earlier posts (Training Fires Versus Real Fires, Live Fire Training: Important Questions) introduced the concepts of live fire training as simulation, physical fidelity, and functional fidelity. This post will dig a bit deeper into what aspects of fidelity may be important in live fire training. Interesting Puzzle Physical fidelity is the extent to which … Read more
As discussed in prior Reading the Fire posts and the ongoing series examining fire behavior indicators (FBI) using the B-SAHF (Building, Smoke, Air Track, Heat, and Flame) organizing scheme, developing proficiency requires practice. This post provides an opportunity to exercise your skills using three video segments shot during a commercial fire. In addition to practicing … Read more

In several recent posts (Training Fires and “Real” Fires and Live Fire Training in Purpose Built Structures, I emphasized that all live fire training is a simulation. Fidelity is the extent to which the simulation replicates reality. Figure 1. Training in an Acquired Structure Note: Ed Hartin Photo The Questions Some firefighters and fire officers … Read more
While I have not had much input (via Twitter or post comments), I have been working on the Building Factors map to include factors related to the surrounding environment and to revise fire protection systems, construction, fuel, size, and ventilation profile. Surrounding Environment Previous versions of the fire behavior indicators (FBI) concept map considered wind … Read more
Last week I had the opportunity to attend the Florida State Fire College’s Live Fire Training Instructor (LFTI) Course held at the Oregon Public Safety Academy. This delivery is part of an effort by the state’s Department of Public Safety Standards and Training (DPSST) to evaluate options for improving safety during live fire training. DPSST … Read more
