___________ is a chemical chain reaction that includes a self-sustaining rapid oxidation
of a fuel accompanied by the release of heat and light. CORRECT ANSWERS Fire
In the combustion process, heat is energy and can be chemical, mechanical, electrical,
or ____________ in origin. CORRECT ANSWERS nuclear
In the combustion process, fuel is the material being burned in the combustion process
and can be a liquid, solid or_________. CORRECT ANSWERS gas
The fourth element of the fire _______________ is the molecular chain reaction, which
allows for a self-sustaining chemical reaction and flame propagation. CORRECT
ANSWERS tetrahedron
Which form of heat transfer involves the transfer of heat by the movement of gases and
liquids? CORRECT ANSWERS Convection
Which form of heat transfer involves the transfer of heat through solid objects, liquids,
and gases? CORRECT ANSWERS Conduction
Which form of heat transfer involves the transfer of heat through invisible waves of
light? CORRECT ANSWERS 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
ANSWERS Incipient stage
What is the lowest temperature that will give off gases of an ignitable mixture than can
self-ignite and sustain burning? CORRECT ANSWERS Ignition Temperature
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
ANSWERS 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 ANSWERS Flashover
Which stage of a fire is occurring when all contents within the perimeter of a structure
are burning? CORRECT ANSWERS Fully developed stage
, Which class of fire involves ordinary combustibles such as paper, cloth, wood, plastics,
and rubber? CORRECT ANSWERS Class A
Which class of fire involves flammable and combustible liquids, gases and greases?
CORRECT ANSWERS Class B
Which class of fire involves energized electrical equipment? CORRECT ANSWERS
Class C
Which class of fire involves combustible metals and alloys such as magnesium, sodium,
lithium and potassium? CORRECT ANSWERS Class D
Which class of fire involves high-temperature combustible cooking fuels such as
vegetable or animal oils and fats? CORRECT ANSWERS 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 ANSWERS National Board of
Fire Underwriters
The process of formally accepting a code and setting it into action is known as:
CORRECT ANSWERS adoption
Which NFPA Standard addresses occupant safety in buildings with regard to the
establishment and maintenance of exits? CORRECT ANSWERS NFPA 101
Exit access, exit, and exit discharge all make up a(n): CORRECT ANSWERS 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 ANSWERS initiation
The _____________ device displays audio or visual signals (or both) to provide stimuli
to alert building occupants of a potential or real fire. CORRECT ANSWERS notification
Smoke detectors and alarms work on one of two basic principles: CORRECT
ANSWERS 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 ANSWERS ionization
