Ventilation
Tactical ventilation is performed during fire attack to: (493) [4.3.11, 4.3.12]
a. quickly extinguish a fully developed fire.
b. limit the need for LDH hose streams.
c. help control the fire.
d. minimize personnel needed on scene. - Answer-c. help control the fire.
Why is ventilation used during overhaul and loss control? (493) [4.3.11, 4.3.12]
a. Evacuate smoke from structures after a fire has been extinguished
b. Eliminate the need for respiratory protection
c. Remove soot and odors from valuable contents
d. To help control the fire - Answer-a. Evacuate smoke from structures after a fire has been extinguished
When performing tactical ventilation, what action has the most impact on successful ventilation? (494)
[4.3.11, 4.3.12]
a. Activating sprinkler systems
b. Exposure protection
c. Controlling oxygen availability
,d. Removing fuel sources - Answer-c. Controlling oxygen availability
Which action may improve visibility inside structures so that interior crews can work more effectively?
(494) [4.3.11, 4.3.12]
a. Exposure protection
b. Increasing the number of personnel
c. Cooling the exterior of the building
d. Controlling exhaust openings - Answer-d. Controlling exhaust openings
As a fire within a compartment consumes oxygen, the amount of unburned fuel in combustion products:
(494) [4.3.11]
a. may either increase or decrease.
b. stays the same..
c. increases
d. decreases. - Answer-c. increases
Why should ventilation be immediately followed with exterior or interior fire attack to cool gases and
surfaces in the fire room? (494) [4.3.11, 4.3.12]
a. Fire will enter ventilation-limited decay when water is applied.
b. The greater the time between ventilation and application of water, the greater the fire's growth.
c. The ventilation crew is already in position to perform fire attack.
d. Ventilation will cause the fire to go into decay, making it easy to extinguish. - Answer-b. The greater
the time between ventilation and application of water, the greater the fire's growth.
What disrupts the ventilation strategy and causes the fire to grow? (494) [4.3.11]
a. Breaking windows unnecessarily
b. Activating sprinkler systems
, c. Changing to a transitional attack
d. Removing items from the structure - Answer-a. Breaking windows unnecessarily
Before interior attack, what action will reduce oxygen available to the fire? (495) [4.3.11]
a. Closing exterior doors and windows
b. Opening exterior doors and windows
c. Directing hose streams to the interior of the structure
d. Directing hose streams on the exterior of the structure - Answer-a. Closing exterior doors and
windows
What occurs when fresh air (oxygen) from ventilation is introduced into a room, causing gases to
reignite and rapid fire development to occur? (495) [4.3.11, 4.3.12]
a. Decay
b. Vaporization
c. Flashover
d. Burst - Answer-c. Flashover
The primary mode of heat transfer from one compartment to another in a structure fire is: (497) [4.3.11,
4.3.12]
a. direct burning.
b. radiation.
c. conduction.
d. convection. - Answer-d. convection.
Water application to a fire compartment begins to transition the fire from: (498) [4.3.11, 4.3.12]
a. growth stage back to the incipient stage.
b. fuel-limited to ventilation-limited conditions.
