o Answer: Convection is heat transfer through the circulation of a fluid (liquid or
gas). Conduction is heat transfer through direct contact between materials.
3. What is the most common toxic gas produced in structure fires?

4. What is the term for the sudden introduction of oxygen into an oxygen-depleted,
superheated space?
, o Answer: Backdraft.
5. What is a flashover?
o Answer: The simultaneous ignition of all combustible materials in a
compartment when the temperature reaches their ignition point.
6. What stage of fire is characterized by fuel-controlled combustion?
o Answer: The growth stage.
7. What does BLEVE stand for?
o Answer: Boiling Liquid Expanding Vapor Explosion.
8. What is the primary expansion ratio of water when it turns to steam?
o Answer: Approximately 1:1700.

11. What is the purpose of the PASS device on an SCBA?
o Answer: To emit a loud audible alarm if a firefighter is motionless for a set period
(typically 20-30 seconds).
12. What is the standard service time for a 30-minute SCBA cylinder?
o Answer: It is not 30 minutes. It is highly variable based on air consumption, but
the rated service time is based on a standard breathing rate. Actual working time
is often much less.
13. What is the "skip-breathing" technique used for?
