combustion? - ANSWER- Chemical chain reaction
Which of the following is the cause of most fire deaths? - ANSWER- Exposure to toxic
gases found in smoke and/or lack of oxygen
How does a compartment fire affect pressure of gases in and around the compartment?
- ANSWER- Heat from a fire increases the pressure of the surrounding gases.
Which of the following is the measuremnt of the average kinetic energy in the particle of
a sample of matter? - ANSWER- Temperature
What is the most common source of heat in combustion reactions? - ANSWER-
Chemical energy
Gases, such as air, used to fill insulation void spaces do not conduct heat very well
because: - ANSWER- Their molecules are relatively far apart

sustain combustion, is its - ANSWER- Flash point
What may occur if water is added to a burning liquid that is less dense that water? -
ANSWER- The water may disperse the burning liquid instead of extinguishing it
The energy release in fire is directly proportional to the - ANSWER- Amount of oxygen
available for combustion
, For combustion to occur after a fuel converts into a gaseous state, the fuel must be
mixed with air (an oxidizer) in the proper ratio, known as the - ANSWER- Flammable
(explosive) range

upon the chracterisitics and configuration of the fuel involved. - ANSWER- Incipient
Which of the following statements BEST describes a fire in the incipient stage? -
ANSWER- The temperature is only slightly above ambient in areas that the fire, plume,
and ceiling jet directly affect
Which of the following may occur during the growrth stage of a compartment fire? -
ANSWER- Isolated or intermittent flames may move through the hot gas layer
Rapid transition from the growth stage to the fully developed stage is known as: -
ANSWER- Flashover
Which of the following can occur during flashover? - ANSWER- The volume of burning
gases can increase to fill the room's entire volume and extend out of any openings from
the room
An increase in ventilation in a space containing a high concentration of heated
flammable gases that lack sufficient oxygen for flaming combustion can result in a -
ANSWER- Backdraft
The flow path of a structure fire is comprised of two regions: the ambient air flow and -
ANSWER- The hot exhause flow out
What will occur if firefighters begin an attack on a ventilation-limited structure fire with
ventilation alone? - ANSWER- The fire's heat release rate and spread will progressively
increase as additional vents are made
Using extinguishing agents other than water and faom to inhibit or interrupt the
combustion reaction is referred to as - ANSWER- Chemical flame inhibition
Most building codes rate the various construction types according to - ANSWER- How
well each construction type maintains its structural integrity over a certain period of time
Which of the following is the most effective means of establishing awareness of hazards
in commercial, industrial, and storage facilities with large fuel loads? - ANSWER-
Performing and updating preincident surveys
In addition to structural members, which of the following can be a significant factor
influencing fire spread and loss of lives in fires? - ANSWER- Combustible interior
finishes and furnishings
