Ventilation Flashcards
Ventilation:
What is the stage where firefighters can effectively operate and extinguish by denying the fire additional oxygen?
An elongated decay stage
Ventilation:
What type of heat is absorbed by the members gear faster? Convective or radiant?
Convective: a result of energy efficient construction compartmentalizing heat.
Ventilation:
Any unusual ventilation profile should be communicated immediately to whom?
The LCO and IC.
Ventilation:
Is vented fire from my building is considered a favorable condition?
No we must still control all venting
Ventilation:
If the officer and count is high heat and heavy smoke without a charged hose line, what should he consider?
Exit the fire area, and limit ventilation
Ventilation:
If fire has not communicated to the floor above, should you vent upstairs?
Only limited ventilation if it facilitates searches
Ventilation:
When should you tell the roof man not to vent the roof?
If you are unable to gain control of the apartment door, or if there is an uncontrolled fire in the hallway
Ventilation:
When should you vent the roof?
Anytime you are not ordered to delay vertical ventilation
Ventilation:
If you were ordered to delay vertical ventilation, can you still open bulkhead and check for victims?
Yes
Ventilation:
When should you tell the officer that you have vertically vented?
When you have completed venting
Ventilation:
When should you vent skylights etc.?
After the fire was extinguished
Ventilation:
If you are on the fire escape and you hear transmissions that there is water on the fire, can you vent the windows?
No, you should prepare to. Only after you coordinate with the LCBO can you vent horizontally.
Ventilation:
When is the fire area considered and IDLH?
When it progresses past the incipient stage
Ventilation:
What is a known life hazard?
Victim that is seen, heard, or you have information from a credible source at the scene.
Ventilation:
When you are venting for search, should you take the window or just open it?
That depends on the conditions. It is up to the member entering the window.
Ventilation:
Before you enter to search, what do you need to do?
Notify the officer.
he might be able to get to the victim quicker and he will tell you not to vent.
Ventilation:
What is the priority action once you vent and enter?
Close the door
Ventilation:
If after your event, a victim is found prior to isolating the room, what should you do next?
Isolate the room and then continue with the rescue effort
Ventilation:
Fire proof: who controls horizontal vent? Who controls vertical vent?
Horizontal is the LCO
Vertical is the IC
Ventilation:
Fire proof: does the person assigned to the roof have to stay at the roof level?
Yes, to ensure that the doors remain closed.
Ventilation:
At a low rise fire proof, which stairway is generally vented early on?
The attack
Ventilation:
At a low rise fire proof when do you usually vent the stair?
Earlier in the operation
Ventilation
Where is the neutral plane during the incipient stage?
Near the top of the door
Ventilation
Can you vent during the elongated decay stage?
Do not! This is when we should be operating to extinguish
