Fire Dynamics for the Fire Service

National Institute of Standards and Technology
100 Bureau Drive
Gaithersburg, MD 20899
 
September 3rd, 2008
9 AM to 3:30 PM
Building 101 – RED Auditorium
 
 
This presentation will discuss how building geometry, materials, furnishings, ventilation and firefighting tactics can influence fire growth and spread leading to untenable conditions for firefighters.  Fire behavior will be described using a combination of videos and data to characterize the thermal environment that firefighters may be exposed to. 
 
Fire behavior or fire dynamics is based on the fundamental relationship between fuel, oxygen and heat, i.e. the fire triangle.  The type of fuel, the location of fuel in the room, the geometry of the fuel, building construction and ventilation can have a significant effect on the speed of fire growth and spread.  Ventilating the structure can provide cooling by removing heat.  But ventilating a “fuel rich” room may cause a flashover, by allowing fresh air into the structure.  It is important to remember that smoke is fuel. Ventilation does not equal cooling.  Understanding ventilation will lead to improved tactical decisions, such as when to use positive pressure ventilation.
