FIRE SUPPRESSION QUESTIONS WITH
DETAILED VERIFIED ANSWERS
Fire Suppression Ans: All of the tactics and tasks that are performed to
achieve extinguishment of the fire
Variety of methods for fire suppression: Ans: - Remove fuel, oxygen, or
heat from the combustion process
- Typically extinguish with water
Size-up Ans: the process of initially evaluating an emergency situation
Size-up is often conducted by the: Ans: first-arriving company officer,
who serves as the Incident Commander until a higher-ranking officer
arrives
The Incident Commander uses the size-up information to: Ans: develop
an IAP, including which type of fire suppression operation to use
When fire fighters advance hose lines toward a building to attack a fire,
the strategy is: Ans: offensive
Defensive operations are conducted from the: Ans: exterior, or while
moving away from the building or fire, by directing water streams toward
the fire from a safe distance
A transitional attack is a: Ans: brief exterior, indirect attack into the fire
compartment to initiate cooling, followed by an interior attack to
suppress the fire
New firefighters are not responsible for determining the type of: Ans:
fire attack to be used
The fire attack is: Ans: - Determined before operation begins
- Continuously evaluated throughout the incident
, Page | 2
- Clearly communicated to and understood by everyone involved
Specific strategies and tactics are usually driven by: Ans: firefighter
safety and victim survive-ability
Defensive operations are used when: Ans: fire is too large to be
controlled by offensive, attack, or risk is too great to fire fighters
Defensive Operations: Ans: - Keep the fire from spreading
- Typically conducted from the exterior
- Large landlines and master streams more often used
- Exposure protection should be a high priority
Offensive operations: Ans: - Exposes fire fighters to heat and smoke
- Objective is for fire fighters to get close enough to the fire to apply
extinguishing agents to burning surfaces
- Used when fire is not too large to be extinguished by applying water
with landlines
*Small hand lines most often used
- Causes least amount of property damage
Transitional attack Ans: During structure fire experiments, researchers
found that applying a limited amount of water through an open window
or door before entering may dramatically improve interior conditions
These experiments showed that can intentional, brief, offensive exterior
attack reduced temperatures in other parts of the house at some distance
from the fire, but it did not completely extinguish the fire: Ans: - It
showed the growth of the fire
- The effects of this offensive exterior is significant but shirt-lived
- Additional water must be applied tot he seat of the fire
, Page | 3
Purpose of Transitional attack: Ans: - Soften the target
- Reduces the risk of flashover
- Improves visibility
- Makes conditions tenable for trapped occupants
Firefighters must learn how to advance and operate both: Ans: large
and small handlines, as well as master stream appliances
Master streams: Ans: - Operated from a fixed position
*On the ground
*On top of the fire apparatus
*On an aerial ladder
*On an aerial platform
- Typically used for defensive operations
- Can also be used to "blitz" a fire
The nozzle defines the: Ans: shape and direction of the water or
extinguishing agent that is discharging onto the fire
A fire stream can be produced with either a: Ans: smooth-bore nozzle or
an adjustable nozzle
Smooth-Bore Nozzle: Ans: A solid stream of water has a greater reach
and penetrating power than a straight stream of water, because it is
discharged as a continuous column of water
Fog-Stream Nozzle Ans: A fog-stream nozzle adjusts to produce either
straight stream or multiple fog-stream patterns
Straight Stream Ans: - Has greater reach than fog stream
