through ongoing research, showing how fire is sustained by a chain
reaction?

B. The fire tetrahedron
,C. The fire polygon
D. The fire pentagon. Answer: B. The Fire tetrahedron
◉ What type of fire is the most recognizable, can be seen by lighting
a match, and requires the presence of a combustible gas because the
visible flame is a gaseous reaction?
A. Spontaneous combustion
B. Premixed flame
C. Diffusion flame
D. Smoldering. Answer: C. Diffusion Flame
◉ Which type of fire has no flame but still generates significant
heat?
A. Spontaneous combustion
B. Premixed flame
C. Diffusion flame
D. Smoldering. Answer: D. Smoldering

source being applied to the combustible material?
A. Spontaneous combustion
B. Premixed flame
C. Diffusion flame
, D. Smoldering. Answer: A. Spontaneous Combustion

air to mix before ignition or combustion occurs?
A. Spontaneous combustion
B. Premixed flame
C. Diffusion flame
D. Smoldering. Answer: B. Premixed flame
◉ Which of the following stages of fire occurs when the heat source,
fuel, and oxygen come together to generate more heat than is
dissipated, thus promoting the uninhibited chain reaction?
A. Incipient stage
B. Free burning stage
C. Flashover stage
D. Smoldering/decay stage. Answer: A. Incipient stage
◉ At which stage will a fire survive by consuming the air and
materials necessary to generate the flammable gas and sustain
combustion?
A. Incipient stage
B. Growth stage
C. Flashover stage
