Application of the B-SAHF (Building, Smoke, Air Track, Heat, & Flame) organizing scheme for critical fire behavior indicators to photographs or video of structure fires provides an excellent opportunity to develop your knowledge of fire behavior and skill in reading the fire. While video provides the opportunity to observe fire behavior indicators over time, still photos also an excellent tool for practice your skill in reading the fire.

Smoke Showing Photography

This Reading the Fire exercise is based on a photo taken by Scott LaPrade, a firefighter assigned to Ladder 1 in Leominster, Massachusetts. Scott has been photographing fires around New England for 25 years. His website, Smoke Showing Photography is an excellent resource when looking for fire photos to practice reading the fire.

Apartment Fire

On February 6, 2009, the Leominster Fire Department received a call for smoke in the building at 77 Cedar Street. Ladder 1 was first due and reported smoke showing from a three-story wood frame apartment building originally built in the 1900s.

Initially light smoke was showing from the roof, but then appeared to dissipate. After companies made entry to investigate, the fire progressed rapidly.

Download and print the B-SAHF Worksheet. Consider the information provided above and examine the following photo. First, describe what you observe in terms of the Building, Smoke, Air Track, Heat, and Flame Indicators. Second, answer the following six questions:

1. What stage(s) may the fire be in (incipient, growth, fully developed, or decay)?
2. What burning regime is the fire likely to be in (fuel or ventilation controlled)?
3. What conditions would you expect to find inside the doorway in the photo?
4. What hazards does the firefighter in does the firefighter in the photo face while working in the doorway?
5. How could these hazards be mitigated?
6. If the fire is on Floor 1 (it was), what are likely avenues for extension in this type of building construction?

Note the kink in the 1-3/4″ (45 mm) hoseline behind the firefighter. Kinks can dramatically reduce flow rate. Watch your hoseline as well as the B-SAHF indicators!

Visit Scott’s website Smoke Showing Photography for additional photos of this incident and extend your practice in Reading the Fire.

Deliberate Practice

Application of the B-SAHF (Building, Smoke, Air Track, Heat, & Flame) organizing scheme for critical fire behavior indicators to photographs or video of structure fires provides an excellent opportunity to develop your knowledge of fire behavior and skill in reading the fire. As you complete this Reading the Fire exercise, think about what you saw and what you did not see. Did you recognize developing conditions, what might you have missed? Watch the video several times. Remember that deliberate practice is focused on continuous improvement and requires repetition of critical skills.

Residential Fire

Download and print the B-SAHF Worksheet and then view the first 25 seconds of the following video of conditions on Side A of a residential fire. First, describe what you observe in terms of the Building, Smoke, Air Track, Heat, and Flame Indicators. Second, answer the following five questions:

1. What additional information would you like to have? How could you obtain it?
2. Where do you think the fire is located?
3. What stage(s) of fire development is the fire likely to be in (incipient, growth, fully developed, or decay)?
4. What burning regime is the fire in (fuel or ventilation controlled)?
5. How would you expect the fire to develop over the next two to three minutes?

Back the video up to the beginning and then watch the first 45 seconds of the clip. Consider the following questions:

1. What changes in in fire behavior did you observe?
2. What fire behavior phenomena occured? What changes in conditions were the likely cause?
3. How could the crew on the hoseline have mitigated the hazards presented by this change in fire behavior?

After completing the B-SAHF exercise, view the remainder of the video. Safe and effective fireground operations require that firefighters and officers are proficient at reading the fire and managing the fire environment. Developing proficiency requires ongoing deliberate practice.

Deliberate Practice

As discussed in my posts on Outstanding Performance and Reading the Fire improving proficiency requires sustained deliberate practice!

Application of the B-SAHF (Building, Smoke, Air Track, Heat, & Flame) organizing scheme for critical fire behavior indicators to photographs or video of structure fires provides an excellent opportunity to develop your knowledge of fire behavior and skill in reading the fire.

Residential Fire

Download and print the B-SAHF Worksheet and then view the first 45 seconds of the following video of conditions on Side C of a residential fire as the crew of Toronto Pumper 223 makes entry into a window on Floor 2, Side A to check for extension from a fire in the basement. First, describe what you observe in terms of the Building, Smoke, Air Track, Heat, and Flame Indicators. Second, answer the following five questions:

1. What additional information would you like to have> How could you obtain it?
2. What state(s) of fire development is the fire likely to be in (incipient, growth, fully developed, or decay)? Remember that fire in adjacent compartments can be in a different stage of development?
3. What burning regime is the fire in (fuel or ventilation controlled)?
4. What conditions would you expect to find on Floor 2? Is the environment tenable for properly protected firefighters?
5. Is it likely that the fire has extended to Floor 2? Why or why not?
6. How would you expect the fire to develop over the next two to three minutes

Back the video up to the beginning and then watch the first three minutes of the clip and consider the following questions:

1. What changes in indicators did you observe prior to the egress of the crew of Pumper 223 from Floor 2?
2. What changes in indicators did you observe following their egress from Floor 2?
3. What might have caused the change in conditions while the crew of Pumper 223 was checking for extension
4. Were there significant indicators of worsening fire behavior visible from the exterior prior to the egress of the members working on Floor 2?
5. What indicators of changing conditions would you have expected on the interior of Floor 2?
6. What tactical options might have reduced the probability of developing untenable conditions on Floor 2?
7. Review your answers on the B-SAHF worksheet. Did any of your answers change based on the additional information provided by the second segment of the video clip? Did you successfully predict the fire behavior that occurred?

After completing the B-SAHF exercise, view the remainder of the video. Placement of the tip of the ladder above the window sill made egress from Floor 2 a bit more difficult. However, Captain Mark Fitzsimmons and Firefighters Geoff Mortimer and Mark Ashcroft from Toronto Pumper 223 escaped without serious harm because they recognized changing conditions and quickly made the decision to exit.

As noted in my earlier post on Flashover & Survival Skills it is essential to train on emergency procedures, but it is even more important to ensure that firefighters and officers are proficient at reading the fire and managing the fire environment to reduce the probability that emergency procedures will be required.

Commercial Fire

Download and print the B-SAHF Worksheet and then view the first 8 seconds of the following video of conditions on Side C of a commercial fire. First, describe what you observe in terms of the Building, Smoke, Air Track, Heat, and Flame Indicators. Second, answer the following five questions:

1. What additional information would you like to have?
   How could you obtain it?
2. What state(s) of fire development is the fire likely to be in (incipient, growth, fully developed, or decay)? Remember that fire in adjacent compartments can be in a different stage of development?
3. What burning regime is the fire in (fuel or ventilation controlled)?
4. What conditions would you expect to find inside this building? Is this likely to be a survivable environment for unprotected occupants? For firefighters?
5. How would you expect the fire to develop over the next two to three minutes?

Back the video up to the beginning, watch the first 15 seconds, and review your answers on the B-SAHF worksheet. Did any of your answers change based on the additional information provided by the view of Side A?
After completing the B-SAHF exercise, view the remainder of the video. Did you successfully predict the fire behavior that occurred? This video provides excellent examples of smoke and air track indicators. However, sometimes the indicators of potential for extreme fire behavior might not be so obvious. Under these circumstances, you will need a higher level of skill to anticipate fire development.

Make it a Habit!

As Geoff Colvin emphasizes in Tallent is Overrated the quantity and quality of deliberate practice is the major determinant in expertise at all levels from novice to expert. Developing skill in reading the fire requires practice. Additional B-SAHF exercises will be posted on a regular basis at cfbt-us.com. Also check the CFBT-US Resources page for additional information on Reading the Fire!

Consider making B-SAHF exercises a regular part of your training schedule. During a recent Compartment Fire Behavior Training (CFBT) Instructor course conducted at Tualatin Valley Fire & Rescue we used B-SAHF drills each morning to help the participants develop skill in reading the fire. However, these drills are equally appropriate for recruit firefighters. Understanding fire behavior and the ability to read the fire and anticipate changes in fire development are critical for everyone working on the fireground!
