and Verified Answers| 100% Correct
Q: Why should firefighters be outside the fire compartment when making an indirect attack
from the interior? (678) [4.3.10]
The fire compartment will not be large enough to conduct an effective indirect attack.
The hose stream will not reach the target if it is inside the fire compartment.
Large volumes of water will make walking areas slippery and dangerous.
A large volume of steam will be created.
Answer:
A large volume of steam will be created.
Q: If a firefighter uses a Z pattern to apply water to the hot gas layer and then the burning fuels
at the floor level, he or she is using a(an) __<\/strong> fire attack. (679) [4.3.10]
transitional
direct
indirect
combination
Answer:
combination
Q: Which type of fire attack involves applying water from the outside of the structure in order
to reduce the potential for flashover and make the environment more survivable for an interior
attack crew? (679) [4.3.10]
Indirect attack
Combination attack
Direct attack
Transitional attack
Answer:
Transitional attack<\/p>\n\n\n\n
will not upset the thermal layering as much as other stream patterns. (679) [4.3.10]
fog
broken
straight
shielded
Answer:
straight
Q: Which statement describes a safety guideline for operations at a multistory building? (681)
[4.3.10]
Firefighters must not use an elevator to get to the fire floor.
Firefighters must not connect the hose to the standpipe on the fire floor.
If the structure does not have a standpipe, firefighters must avoid using the stairwell nearest to
the fire.
If the standpipe is in a protected stairwell, the hose must be connected on the floor above the fire.
Answer:
Firefighters must not use an elevator to get to the fire floor.
Q: Which is a characteristic of fires in residential basements? (682) [4.3.10]
The safest path into a basement fire is through an interior enclosed stairwell.
Residential basement fires tend to be fuel-limited rather than ventilation-limited.
FireFighters working on the floor above the basement fire are at an increased risk of floor
collapse.
Sounding the floor is the best way to determine whether it is safe to work on the floor above a
basement fire.
Answer:
FireFighters working on the floor above the basement fire are at an increased risk of floor
collapse.
Q: Which method of attack would put firefighters at the least risk when fighting a residential
basement fire? (683) [4.3.10]<\/p>\n\n\n\n
Entering through an enclosed interior stairwell
Advancing down the stairwell while using a fog stream for protection
Entering on the first floor and installing a cellar nozzle
Answer:
Applying water through an exterior basement window
Q: Which is an example of protecting interior exposures? (684) [4.3.10]
Performing negative pressure ventilation
Closing a door between the fire and unaffected area
Deactivating sprinklers once the fire is extinguished
Applying water to the hot gas layer
Answer:
Closing a door between the fire and unaffected area
Q: In a building that is protected by control mode sprinklers, firefighters need to: (685) [4.3.14]
complete suppression before turning off the system.
perform fire attack from outside the fire compartment.
stay back and allow the sprinklers to put out the fire.
turn the system off before entering the building
Answer:
complete suppression before turning off the system.
Q: Which action would be taken first when performing suppression operations at a structure
protected by automatic sprinklers? (685) [4.3.14]
Closing the main sprinkler control valve
Advancing attack hose to the fire floor
Testing the sprinkler system
Connecting the pumper to the FDC
Answer:
Connecting the pumper to the FDC<\/p>\n\n\n\n
[4.3.13, 4.3.14]
Upon arrival at the structure
Immediately prior to fire attack
Once the pumper has been connected to the FDC
Once the fire is under control and the IC gives the order
Answer:
Once the fire is under control and the IC gives the order
Q: When firefighters apply water to the hot gas layer in a compartment, it will: (670) [4.3.10]
increase the potential for flashover.
increase the radiant heat flux from the upper layer.
reduce the radiant heat flux from the upper layer.
push fire into adjacent rooms.
Answer:
reduce the radiant heat flux from the upper layer.
Q: What can happen if excess steam is produced inside the structure as a result of applying
water on the fire? (670) [4.3.10]
Disruption of the thermal layering
Increase in the potential for backdraft or flashover
Transition from fuel-limited to ventilation-limited conditions
Pyrolysis process speeds up
Answer:
Disruption of the thermal layering
Q: In which situation would fuel removal be a likely method of extinguishment? (670) [4.3.19]
Fire in an apartment building
Fire in a one-story house
Grass fire
