smoke; crib fires; fire suppression; furniture
calorimeters; crib burning; chemical properties;
extinguishment; physical properties
The impact of fire suppression agentson the quanity and
composition of smoke generated furing extinguishment has
been investigated in two series of crib fires. Both
series examined the physical and chemical properties of
smoke from crib fires before, during and after
extinguishment. Fire fighters have observed that a
cloud of very bright "white smoke" is often generated as
they extinguish a fire using a fire suppression agent.
This "white smoke" is not usually observed when they use
water to extinguish fires. Questions have arisen
concerning what causes the generation of "white smoke"
and whether or not it represents a significant new
hazard for fire fighters.
