203.01.10 Response and Actions Flashcards
Which engines will secure a water source in response to a structure fire?
A source of water supply shall be secured by the first two (2) due-in Engine Companies unless the pre-plan preempts this requirement. Third (3rd) Engine to Level 1 Stage at next closest hydrant and only secure water supply at the direction of Command
What size/type of hose should be used for water supply?
The water supply should be a 5” supply line, or soft suction
On narrow or dead-end streets where access will be limited, Engine Companies should consider utilizing:
A reverse lay (Crossfire) to a hydrant past the address to allow unimpeded access for the first arriving Ladder Company
In the event a supply source or line cannot be secured, the Officer of the Engine Company must:
Notify Command immediately. Later arriving Companies may need to relay water to this Engine Company.
For each supply hose lay, over _______ an Engine Company shall be placed to boost pressure and relay water to the initial attack Engine Company
1000 feet
For Defensive or Large GPM operations, FAO’s should ensure the 5” supply is coming directly into:
The side intake to provide maximum GPM flow into the fire pump and avoid any friction loss from the front intake piping
What line can be used for most fires (i.e., one or two rooms in a residential fire, multi-families, compartmentalized areas)?
1-3/4 inch attack line
A 2-1/2 fire line shall be used for the following:
Commercial, Industrial, Retail, Auto Repair
Shops, Churches or High Rise Occupancies
For obvious defensive operations, what size tips should be used on the ATTACK LINE?
1-1/4” or 1-3/8”
What is the most important means of egress to protect?
The interior stairs
Where should the first line be placed (typically)?
Between fire and victims via the primary means of egress
Where should the second line be placed (typically)?
i. Back-up first line in the event of failure of the first line by providing additional GPM in the event the first line can’t control the fire.
ii. Position to control exposures in the event the first line didn’t control exposures initially.
iii. Position on interior if the first engine chooses to protect exposures, protect trapped occupants.
iv. Floor above if not needed for back up because the 1 line is controlling the fire. ENSURE SECOND LINE IS SUFFICIENT TO REACH THE FLOOR ABOVE.
v. Fire line choice must be the same size or larger than the first line.
Where should the third line be placed?
i. As directed by Command.
ii. Cover secondary means of egress.
iii. Protect trapped occupants above the fire, on fire escapes or
in any type of danger.
iv. Exposure control, line deployment into exposed buildings
v. Vertical extension to floors above or other areas if
necessary
True or False: First two Engine Companies shall always work to put the first line into service
True
Do not operate fire streams into smoke unless:
You are encountering extreme levels of heat or suspect unseen rollover or black fire, which will lead to a flashover, or rapid-fire spread event
The largest tip size should be utilized initially on the mounted master stream device, preferably the:
2-inch tip
If no exterior stairs or door to access the basement and
HEAVY FIRE CONDITIONS EXIST WITHIN THE BASEMENT, then “knock down” fire from:
An exterior window prior to attempting to enter from interior steps
Where should the second and third lines be placed in a basement fire?
iii. If safe to do so, the second line must go to the interior of the building at the steps to the basement and protect the rest of the building from vertical extension.
iv. Third line may back-up either line or go to top floor for extension control.
What type of fires should Class A foam be used?
Class A foam shall be used on all offensive, interior attack
lines unless specifically instructed to not use the foam by the Company officer or Incident Commander. Don’t wait for the foam to be called for, use it on all fires.
What type of fires should Class A foam NOT be used on?
Class A foam shall not be utilized for defensive or master stream operations
First Arriving Engine, position apparatus to not impeded access to structure for the Ladder Co., this is done by?
Pulling past the structure
