A meaningful analysis of a fire requires an understanding of the fire
growth, the total heat released, and WHAT? - ✔✔✔ Correct Answer > Heat
Release Rate
If the current flowing out from an electrical panel is 12.5 amps, and it
then flows through an electrical load of 1500 watts, what is the
amperage of the remaining current flow of the return circuit? - ✔✔✔
Correct Answer > 12.5
What does he term AFCI stand for? And, the "A" specifically represents
what? - ✔✔✔ Correct Answer > Arc-fault circuit interrupter
,The fire characteristic that most affects fire growth during the pre-
flashover phase of a fire - ✔✔✔ Correct Answer > Heat Release Rate
A deflagration resulting from the sudden introduction of air into a
confined space containing oxygen-deficient products of incomplete
combustion - ✔✔✔ Correct Answer > Backdraft
The transport of heat energy from one point to another point, caused
by temperature difference between those points - ✔✔✔ Correct Answer
> Heat transfer
The organization that develops standard methods for testing materials -
✔✔✔ Correct Answer > ASTM
Initiation of combustion by heat but without a spark or flame - ✔✔✔
Correct Answer > Auto-ignition
,An explosion caused by a combination of combustible materials heated
to the ignition point and a sudden introduction of oxygen to support
combustion - ✔✔✔ Correct Answer > Backdraft
If a hair dryer draws 8.3amps (in a home with 120-volt service), what is

Flashover? - ✔✔✔ Correct Answer > 1100°F
The temperature at which copper melts - ✔✔✔ Correct Answer > 1960°F
The measurement of the radiant heat flux (from gas layer to the floor)
that indicates the onset of flashover - ✔✔✔ Correct Answer > 2 W/cm2
The voltage between the two hot wires at the service entrance cables
in most single-family residences in the United States (single-phase
service with three wires) - ✔✔✔ Correct Answer > 240 volts
The revision cycle for NFPA 921 (timespan) - ✔✔✔ Correct Answer > 3 years
The flash point of power steering fluid - ✔✔✔ Correct Answer > 350°F
In high-pressure fuel-injected vehicles, this is the typical range of
pressure that is used to pump fuel from a fuel tank - ✔✔✔ Correct Answer
> 35-70 p.s.i.
