IFSTA CHAPTER 14: FIRE SUPPRESSION
QUESTIONS WITH VERIFIED ANSWERS
2026/2027
1. Which strategic mode is most appropriate when the fire is spreading faster than the
resources can contain it, and the risk to personnel outweighs the potential for saving
property?
A. Offensive strategy
B. Combination strategy
C. Defensive strategy
D. Marginal strategy
Answer: C
Conceptual Explanation: A defensive strategy is chosen when the risk to firefighters is too
great or resources are insufficient to control the fire; it focuses on protecting exposures.
2. When conducting an interior fire attack, what is the primary purpose of a backup hoseline?
A. To provide additional flow for the primary attack
B. To protect the primary attack team and their egress route
C. To extinguish fires in adjacent rooms
,D. To be used for hydraulic ventilation
Answer: B
Conceptual Explanation: The primary purpose of a backup line is to protect the attack
team’s exit and provide safety if the fire worsens or the primary line fails.
3. In which type of attack is water applied directly onto the burning fuel until the fire is
extinguished?
A. Indirect attack
B. Combination attack
C. Shielded attack
D. Direct attack
Answer: D
Conceptual Explanation: A direct attack involves applying water directly to the seat of the
fire, usually in short bursts or a solid stream.
4. What is the primary danger of using an indirect fire attack in an occupied building?
A. It uses too much water and causes collapse
B. It increases the oxygen level in the room
C. It displaces the thermal layer and can steam-burn occupants or firefighters
D. It is ineffective against Class A materials
, Answer: C
Conceptual Explanation: Indirect attacks create large amounts of steam which can disrupt
the thermal balance and cause serious burns if the area is not ventilated or is occupied.
5. A combination attack involves using a fog stream in a ‘T’, ‘Z’, or ‘O’ pattern to do what?
A. Conserve water while maintaining high pressure
B. Ventilate the room and extinguish the fire simultaneously
C. Prevent flashover while retreating
D. Cool the overhead gases and then the fuel surface
Answer: D
Conceptual Explanation: The combination attack combines steam production for gas
cooling with direct application on the fuel.
6. When deploying a master stream device, what is the maximum number of firefighters
required to man the nozzle once it is set and secured?
A. Two firefighters
B. Zero (it should be unmanned)
C. One firefighter
D. Four firefighters
Answer: B
