Flashcards in Taxpayer Deck (18):
When two handlines are operating on an advanced fire in a store
special call an extra engine and ladder
Transmit a second alarm for
> extension to the cockloft
> extension to the adjoining occupancy
> or for an advanced fire in the cellar.
If fire is in the cellar the ladder company officer can give permission to remove the window after communication and coordination.
If a Store/Cockloft fire it must be communicated and coordinated with ladder company officer, IC must give permission, and a charged line must be present.
A hole _____________, where possible, is recommended.
8' x 8'
When it is not possible to make an eight feet by eight feet cut in a serious cockloft fire or where a heavy heat and smoke condition exists in the cockloft, the largest opening possible shall be made.
The immediate ventilation and cutting of an effective size hole on the roof calls for _______________________________ on the roof.
A Roof Sector Supervisor must supervise roof operations when
two saws and four members
more than one power saw is working on the roof.
In many cases where entry is delayed or where the pulling of ceilings is impossible due to fire conditions or ceiling construction, a hoseline or lines operated properly into a trench cut may confine the fire.
Before these lines are operated all members in the stores must be withdrawn.
Tactics (store fires)
The first arriving engines must position their lines if possible, between the people and the fire.
Break the store front windows for line advancement and leave the exit doors free for the people to use.
The first two hand lines should be stretched to the store involved.
Additional lines should be stretched to the adjoining stores.
A line may also be required on the roof to protect personnel and exposures once the roof is opened.
Tactics (cockloft fires)
Operate hoselines directly into roof openings. This generally is not a good practice but in some cases may be the only way of hitting the fire and controlling it.
Note: Before lines are operated into the roof all interior operations must cease or personnel withdrawn to a safe area. It must be remembered that the primary purpose of roof lines is to protect members operating on the roof and prevent fire extension to exposures.
First engine company: -
When fire has control of the cockloft and the need for exposure protection is critical, position the engine to utilize the deckpipe.
Stretch a handline into the most seriously exposed occupancy/building, depending on life hazard and the location and severity of the fire.
When exposures are not an immediate problem, then the first line should be stretched into the store under the main body of fire and operated to extinguish the fire.
Second engine company: - When fire has control of the cockloft
assist first engine with initial line.
When staffing and conditions permit, stretch a line into another seriously exposed building/occupancy and operate into the cockloft to confine and extinguish the fire.
It may be advisable to skip stores in order to confine a cockloft fire.
The roof firefighter or Roof Sector Supervisor, when assigned, should relay information on the following to the Incident Commander:
A. Size and shape of the building.
B. Location and volume of fire or smoke.
C. Exposures-sides and rear.
D. Roof loading-signs, machinery, etc.
E. Evidence of cockloft fire.
F. Roof construction.
- Presence (or absence) of extending parapets or evidence of fire walls.
- Differences in levels of the roof
- Cornices - information on height, depth, opening into cockloft, etc.
- False fronts extending over the roof.
