Basic Firefighter 1 Exam
Questions and Answers 100%
PASS
Three (3) Physical State of Matter in which FUEL EXISTS.—ANSWER-1. Solids
2. Liquids
3. Gases
Three (3) ways HEAT is transfered—ANSWER-1. Conduction
2. Convection
3. Radiation
Heat Transferred by an intervening Heat-conducting medium or by the direct contact of two
bodies—ANSWER-CONDUCTION
Note: Not all materials conduct heat similarly.
Four (4) products of combustion—ANSWER-1. Heat
2. Smoke
3. Gases
4. Light (Flame)
,Three (3) MAIN progressive phases or stages of a Fire—ANSWER-1. Incipient (or beginning)
Phase
2. Steady-State Burning (or Free burning) Phase
3. Hot-Smoldering Phase
Characteristics of liquid fuels which increases Difficulty of Extinguishment—ANSWER-Liquids
Assume the shape of their container.
Heat transferred by the movement of air, other gases or liquids.
FORM OF HEAT TRANSFER—ANSWER-Convection
Note: Heat transferred by convection usually occurs in an upward direction.
The Four (4) elements of the Fire Tetrahedron—ANSWER-1. Fuel (Reducing Agent)
2. Oxygen (Oxidizing Agent)
3. Heat (Temperature)
4. Chemical Chain Reaction
Mode of Combustion
Associated with the Fire Triangle—ANSWER-Smoldering Mode of Combustion
Occurs when unburned combustible gases which accumulate at the ceiling level are pushed
into uninvolved areas where they mix with oxygen and upon reaching their flammable
range, ignite and expand rapidly rolling over the ceiling.—ANSWER-Rollover
Note: unlike a Flashover, in a Rollover only the gases are burning, not the contents of the
room.

, Four (4) methods used to extinguish fire.—ANSWER-1. Elimination of Fuel
2. Exclusion of Oxygen
3. Reduction of Temperature
4. Inhibition of the Chemical Chain Reaction
Mode of combustion associated with the fire tetrahedron—ANSWER-Flaming Mode of
Combustion
Terms for process by which gases evolve from solid fuels when they are heated and for
processes by which gases evolve from liquid fuels.—ANSWER-Solid Fuels - Pyrolysis
Liquid Fuels - Vaporization
Density of gases in relation to air—ANSWER-Vapor Density
The Vapor Density of Air is 1
Gas which supports combustion—ANSWER-Oxygen
Fire phase when portable fire extinguishers may be most effective—ANSWER-Incipient
Phase
Caused by an excessive buildup of heat, flames fully involve and entire area or surface—
ANSWER-Flashover
Definition of Combustion—ANSWER-The self-sustaining process of rapid oxidation of a fuel
producing light and heat.
Involves flammable liquids, greases and gasses
CLASSIFICATION OF FIRE—ANSWER-Class B
