(2) TB 063 - Procedures for Supplementing High Rise Fire Pumps Flashcards
The high-rise pumping procedures will be implemented on buildings with a building fire pump supplying the standpipe systems.
This includes the following high-rise buildings:
•high-rise buildings built between 1960 and 1974 higher than 150 ft
•high rise buildings between 75 and 150 feet that have been retrofitted to include a fire pump
•high-rise built after 1974
At an emergency, and a FDC system pressure sign is not provided, an estimate of the building’s system pressure can be calculated by?
multiplying the number of floors by 5, then adding the constant of 150 psi.
The member responsible for supplying the water system to a high rise will be?
the first arriving 200 series engineer, or in the event that the first two arriving companies on scene are single engines, the second arriving engineer will supply the system.
Each 2-1/2” hose attached to a high rise FDC shall be a maximum of ______ ft.
100 ft
2-1/2” Lines that are connected to the FDC
If pumping over _____ psi, strap the lines together using ladder straps on EACH SIDE of each COUPLING and MIDWAY between each coupling. Load the lines BEFORE strapping.
300 PSI
If the high rise is over _____ stories or the system pressure at the FDC is over _____ psi, another apparatus shall spot to the hydrant/4-way and pump HALF the system pressure to the apparatus supplying the FDC’s.
Over 20 stories
Or over 250 PSI
If there is a fire, pump into the system ____ PSI BELOW THE SYSTEM PRESSURE as shown on FDC sign or on the calculated estimate.
100 PSI
(This allows apparatus pump pressure to be below the ON/OFF pressure settings of the building fire pump. This will allow the building fire pump to perform its designed function of supplying the system.)
If there is an ACTUAL FIRE, whether the Engineer is supplying the FDC with one apparatus, or two apparatus pumping in series, request additional engines from the Incident Commander and have them do what?
duplicate the operation into the other two inlets of the FDC utilizing a SEPARATE source of water, if possible, for the supply lines.
Once the Engineer is hooked up and pumping to the FDC, determine if the water is flowing or not and notify the ______ to this fact.
Incident Commander
At the scene of a high rise fire, danger from falling glass and debris is a genuine concern.
The engineer pumping to the FDC can protect himself by one of more of the following:
l. Donning all safety clothing
- Having a truck company spot their aerial so as to cover both the panel and the FDC’s. Once spotted, lay salvage covers, folded to a quarter of their width, on the rungs from the pedestal to the top of the aerial.
- Spotting a second apparatus next to your engine and using a pike pole and salvage cover, create a roof over the panel.
- Creating a lean-to over the panel out of pike poles, rubbish hooks and salvage covers.
- Draping rubbish carriers, salvage covers or other such suitable barriers over the offside running board to the ground to protect the legs from the horizontal spread of flying glass shards.
Protection for the 2 1/2” hose can be accomplished by using:
-ladders
-salvage covers
-seat cushions
-compartment or hose bed liners (wood slats).
Once the Engineer is hooked up to the FDC and pumping 100 psi below system pressure, he needs to determine if the water is flowing or not.
An expedient way to determine if water is flowing is to ________.
-feather the discharge gate
(If the gate resists closing and/or there is a drop on the discharge gauge, water is flowing. If the water is static, the closing of the gate is easily accomplished)
The quickest and most reliable way to identify the building system pressure is to locate _________.
The Fire Department Connection (FDC)
If fire pump fails, Fire Department apparatus will be required to assume the building fire pump’s function of maintaining the system pressure.
The system pressure is defined as?
Head pressure plus friction loss in the standpipe inlets plus pressure required at the HIGHEST outlet.
