Taxpayers Flashcards
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, adjoining occupancy or for an advanced fire in the cellar. The need for additional ladder companies at these operations is great, anticipate such and special call as needed.
7.1.2 When heavy or medium fire conditions are encountered the initial lines should be 2-1/2 inch. These lines can later be used to supply distributors, cellar pipes and heavy stream appliances. If the striking power and the water capability of 2-1/2 inch hoselines are not required, after the initial attack, they can be reduced to 1-3/4 inch lines for subsequent operations.
- 1.3 Supplying a sprinkler system is to be given a high priority after the establishment of the initial line.
- 1.4 When compatible with fire conditions, 1-3/4 inch lines may be used in exposures.
7.1.7 For a fire that is traveling rapidly along a row of stores in a taxpayer it may be best to skip stores and stretch lines into alternate stores ahead of the fire. The by- passed stores will be covered by subsequent lines.
cellar taxpayer
-When the line can advance down the cellar stairs it should do so. A second hoseline must be stretched to the top of the stairs to protect the members in the cellar and prevent the upward extension of the fire.
If it is impossible to stretch a line into the cellar via the interior stairs, lines must be operated from front or rear exterior entrances. Use caution and do not have lines opposing one another. Advancing two lines into the cellar simultaneously may control the fire.
Cellars of large area or heavy fire conditions may require two lines advancing in unison. If these lines do not control the fire, heavy outside streams will be required.
When fire conditions or collapse potential make it necessary to keep personnel out of the cellar, considerations must be given to the use of high expansion foam, cellar pipes and distributors to control the fire.
Cellar fire taxpayer:
-First engine company: - Stretch the first line into the occupancy above the fire to prevent vertical extension. In a building protected by a sprinkler system, if staffing and conditions permit, a second line shall be stretched to feed this system.
-
Second engine company: - Assist first engine with initial line. In a building protected by a sprinkler system, when first engine has not supplied it and staffing and conditions permit, a second line shall be stretched to feed this system. After supplying the sprinkler system, when staffing and conditions permit, stretch a line to backup first engine company’s line which may be used for any of the following:
1. To control the first floor if the first engine company has advanced into the cellar via the interior cellar entrance.
2. Serve as a backup or protection line for the first engine company.
3. Stretch into the cellar via the interior stairs or the outside entrance if the first unit’s line has to control the first floor.
4. To employ the use of cellar pipes or distributors over the fire.
Third engine company: - Ensure sprinkler system is supplied. When second engine is assisting with first line, stretch a second line which may be used as in section B, subsections 1 through 4 above.
Store Fires
First engine company: - Stretch the first line into the involved store to protect life and extinguish the fire. In a building protected by a sprinkler system, when staffing and conditions permit, a second line shall be stretched to feed this system.
Second engine company: - Assist first engine with initial line. In a building protected by a sprinkler system, when first engine has not supplied it and staffing and conditions permit, a second line shall be stretched to feed this system. After supplying the sprinkler system, when staffing and conditions permit, stretch a line to backup first engine company’s line.
Third engine company: - Ensure sprinkler system is supplied. Stretch a line and operate as ordered by the Incident Commander.
Cockloft Fires
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. In-line pumping will give good positioning and allow room for placement of a tower ladder.
1. Stretch a handline into the most seriously exposed occupancy/building, depending on life hazard and the location and severity of the fire.
2. Refer to Section 7.1.2 and 7.1.4 for hose sizes and operating procedures.
3. 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, and the need for exposure protection is critical, 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.
–Third engine company: - Ensure sprinkler system is supplied. Stretch a line and operate as ordered by the Incident Commander.
