___________ is a chemical chain reaction that includes a self-sustaining rapid oxidation of a fuel
accompanied by the release of heat and light. - (Correct Answer)-Fire
In the combustion process, heat is energy and can be chemical, mechanical, electrical, or
____________ in origin. - (Correct Answer)-nuclear
In the combustion process, fuel is the material being burned in the combustion process and can
be a liquid, solid or_________. - (Correct Answer)-gas
The fourth element of the fire _______________ is the molecular chain reaction, which allows
for a self-sustaining chemical reaction and flame propagation. - (Correct Answer)-tetrahedron
Which form of heat transfer involves the transfer of heat by the movement of gases and liquids? -
(Correct Answer)-Convection
Which form of heat transfer involves the transfer of heat through solid objects, liquids, and
gases? - (Correct Answer)-Conduction
Which form of heat transfer involves the transfer of heat through invisible waves of light? -
(Correct Answer)-Radiation
Which stage of a fire is occurring when a form of energy transfer, usually heat, generates gas
from a fuel source so the fuel is able to mix with the air? - (Correct Answer)-Incipient stage
What is the lowest temperature that will give off gases of an ignitable mixture than can self-
ignite and sustain burning? - (Correct Answer)-Ignition Temperature
, 2
Which stage of fire is occurring when other combustibles heat up, giving off flammable gases,
and igniting and spreading a chain reaction to other flammables? - (Correct Answer)-Growth
stage
What occurs during the transition between the growth phase and the fully developed stage and is
the point at which all contents of a room reach their ignition temperatures and quickly change to
a fully developed fire? - (Correct Answer)-Flashover
Which stage of a fire is occurring when all contents within the perimeter of a structure are
burning? - (Correct Answer)-Fully developed stage
Which class of fire involves ordinary combustibles such as paper, cloth, wood, plastics, and
rubber? - (Correct Answer)-Class A
Which class of fire involves flammable and combustible liquids, gases and greases? - (Correct
Answer)-Class B
Which class of fire involves energized electrical equipment? - (Correct Answer)-Class C
Which class of fire involves combustible metals and alloys such as magnesium, sodium, lithium
and potassium? - (Correct Answer)-Class D
Which class of fire involves high-temperature combustible cooking fuels such as vegetable or
animal oils and fats? - (Correct Answer)-Class K
What organization, formed in 1866, served as the foundation for many of today's fire service and
construction codes, municipal water supply and alarm systems, fire apparatus, and fire insurance
rating systems? - (Correct Answer)-National Board of Fire Underwriters
, 3
The process of formally accepting a code and setting it into action is known as: - (Correct
Answer)-adoption
Which NFPA Standard addresses occupant safety in buildings with regard to the establishment
and maintenance of exits? - (Correct Answer)-NFPA 101
Exit access, exit, and exit discharge all make up a(n): - (Correct Answer)-means of egress
A(n) _____________ device senses the presence of heat or smoke, detects a sprinkler activation
or a triggered manual activation and sends a signal to the control panel. - (Correct Answer)-
initiation
The _____________ device displays audio or visual signals (or both) to provide stimuli to alert
building occupants of a potential or real fire. - (Correct Answer)-notification
Smoke detectors and alarms work on one of two basic principles: - (Correct Answer)-ionization
and photoelectric
A(n) ______________ smoke detector/alarm works by using a small amount of a radioactive
material that electrically charges air particles to produce a measurable current in the sensing
chamber and when smoke enters the chamber, the flow of ions to the electrode changes and the
alarm is activated. - (Correct Answer)-ionization
A(n) _____________ smoke detector/alarm operates by using a light source aimed at a light
sensor within the sensing chamber to initiate an alarm when the light source reflects or obscures
smoke particles. - (Correct Answer)-photoelectric
What type of sprinkler system is used in areas subject to freezing? - (Correct Answer)-Dry pipe
