Check back soon for video updates to see how scientific fire analysis can help you.
The use of fire modeling can help demonstrate various principles of fire behavior often misunderstood by fire professionals. One such example is by demonstrating how elevated fires can spread to areas well away from their origin causing far more damage to items not responsible for the fire. Confusion of such issues can lead to erroneous conclusions as to where and how a fire started. Is your product or your client being wrongly accused of starting a fire?
Arched Roof Space Smoke Flow
This is an example of a computer fire modeling run that demonstrates the flow of smoke expected from a fire in a corner of a large space with an arched roof. Demonstrations such as this enable investigators to consider various fluid (smoke) flow scenarios and how they compare with hypotheses as to fire development.
Fire Model - Sprinkler Activation
This is an example of how a computer fire model can be used to estimate sprinkler activation times even in a complex geometry such as an arched roof. The results can be presented in a graphic format as shown here. In this instance, the smoke which would otherwise obscure the sprinkler is removed for easier viewing.
Seeing is Believing
The science of fire behavior involves many fields such as chemistry, heat transfer, fluid dynamics and others. This clip shows flames moving away from the fuel and burning at an outside opening, something many say does not occur. How can that happen?

Chico Elevated Fire
This video was taken of a elevated fire test coordinated by Carman & Associates Fire Investigation in coordination with the Chico, California Fire Department and the Northern California CCAI Roundtable.
Many thanks to all who made this possible.
Denver Elevated Fire Test
This fire was started in a pan of oil the base of which was elevated to typical kitchen counter height. The oil was ignited and the flames grew and impinged upon the OSB cabinets above. Note the length of time of direct flame impingement and lack of overall fire growth. Only after a firefighter added additional fuel (thermoplastics and denatured alcohol) did the fire become sufficiently energetic and unstable to grow much beyond the initial conditions.
The fire had been burning for about 5 minutes at the time of the start of the video.
Elevated Fire ignited at kitchen counter level in a 16' x 24', two-room burn cell at the Pacific Northwest Fire Investigators' Assn conference in May 2013. The video starts after approximately 20 minutes of burning at about the same heat release rate as seen at the beginning of this video.
