TOPIC 1: FIRE DYNAMICS
10 Questions • 10.0% of Exam • This topic covers the principles of fire behavior, including combustion and heat transfer mechanisms.
QUESTION 1
A fire is burning in a room with a volume of 10000 cubic meters. If the oxygen content in
the room is 20% by volume and the fire is consuming oxygen at a rate of 10 cubic
meters per minute, what is the duration of the fire assuming no other factors affecting
oxygen consumption?
[A] 20 minutes
[B] 30 minutes
[C] 45 minutes
[D] None of the above
Correct Answer: D. None of the above.
Rationale: Oxygen consumption rate is 10 cubic meters per minute. The total volume of oxygen available in the room is
2000 cubic meters (20% of 10000). So, the oxygen will last for 200 minutes (2000/10).
QUESTION 2
A fire is classified as a class C fire. What type of material is most likely to be involved in
this type of fire?
[A] Class A materials (wood, paper, etc.)
[B] Class B materials (flammable liquids)
[C] Class C materials (electrical equipment)
[D] Class D materials (combustible metals)
Correct Answer: C. Class C materials (electrical equipment)
Rationale: Class C fires involve electrical equipment as the ignition source and fuel.

QUESTION 3
What is the term for a fire that is burning in a confined space?
[A] Class A fire
[B] Class B fire
[C] Class C fire
[D] Vented fire
Correct Answer: D. Vented fire.
Rationale: A vented fire is a fire that is burning in a confined space with adequate ventilation.
QUESTION 4
A fire that ignites without an external source of ignition, such as a spark, is classified
as a _______________________ fire.
[A] Spontaneous ignition
[B] Spontaneous combustion
[C] Incendiary device
[D] Electrical fault
Correct Answer: Spontaneous ignition.
Rationale: Spontaneous ignition is a type of fire that ignites without an external source of ignition, often due to internal heat
generation within a material.
