The key difference between a smoke explosion and backdraft is ________
pg 312
-with backdraft, the mixture of smoke and air is extremely fuel rich (>10%)
Smoke explosions require fuel and air within its flammable range
Occurs when unburned gasses contact ignition
involves premixed fuel and oxygen
Similar to ignition of propane and air within its flammable range.
pg. 312
Smoke explosion
A smoke explosion may occur
pg 312
Before or after the decay stage.
Air current changing direction, neutral plane lifting, or smoke rushing out are indicators of_________
pg 312
Potential rapid fire development
Backdraft occurs in the ______ stage.
pg 311
Decay stage
What are the four common elements of flashover?
pg 310
Transition in fire development
Growth stage to fully developed
Rapidity
Compartment
Ignition of all exposed surfaces
Minimum temperature to which a fuel (other than a liquid) in the air must be heated in order to start self sustained combustion.
pg 309
Auto ignition temperature
Moment when a mixture of fuel and oxygen encounters an external heat source sufficient to start the combustion process.
pg 309
Piloted Ignition
Thermal layering of gases is also known as ____________
pg. 308
Heat stratification
Thermal or chemical decomposition of fuel because of heat, generally resulting in lowered ignition temperature of the material; the pre ignition combustion phase of burning during which heat energy is absorbed by the fuel, in turn giving off flammable tars pitches and gases.
Pyrolysis
Transmission of heat energy from one body to another body at a lower temp through electromagnetic waves such as infrared thermal waves, radio waves or X rays.
Radiation
Transfer of heat by the movement of heated fluids or gases usually in an upward direction.
Convection
Physical flow or transfer of heat energy from one body to another , through direct contact.
Conduction
Heat is transferred from one object to another by_________
Conduction
Convection
radiation

(draft curtains)
Noncombustible barriers or dividers hung from the ceiling in large open areas that are designed to minimize the mushrooming effect of heat and smoke and impede the flow of heat.
