FFP - HIGH RISE OFFICE BUILDINGS Flashcards
DC Beckham is drilling with members of a Midtown Engine company on the use of manual fire pumps at High Rise Office Buildings. In how many points was the Chief correct?
- An ECC should be assigned to either assist the building engineer or to start and operate the building fire pumps.
- Most high rise buildings have two pumps side by side which are connected in the parallel position.
- The operation of these pumps differs from building to building even though the layout is usually similar.
- Near each fire pump is a standpipe phone providing direct communication with the Incident Command Post.
- The building fire pumps may not be capable of supplying adequate nozzle pressure to hose lines at upper floors. The primary supply for firefighting in most operations shall be Fire Department pumpers.
- A good rule of thumb is to have a separate Engine supply the standpipe system for each hand line in operation.

B) 250 psi
C) 350 psi
D) 80 psi
ANSWER: A) 300 psi
(HROB 4.1.7 / Engine Ops 9, Add 1, 2.1)

- If possible, the SAE Group Supervisor shall choose a location on a floor which is not serviced by the same bank of elevators as the fire floor and at least five floors above the fire floor.
- For a fire on a floor serviced by a high rise bank of elevators, the SAE Group Supervisor would be located at least five floors above the fire floor.
- In this scenario the fire is on the 24th floor, therefore the SAE Group Supervisor would select a floor which is not serviced by the same bank as the fire floor. (BANK C)
- B Bank goes from 20-40 so the SAE Group Supervisor would choose the C Bank 40-60.
- SAE will never establish himself in the sky lobby of an elevator bank because of a concern of mushrooming. Therefore he would not go to the 40th floor because the B Bank also services that floor.
You have been ordered by the IC to ensure that the building fire pump is operating at the correct pump discharge pressure for a fire on the 29th floor of a HROB. You would know that the pump should be set to which recommended pressure listed below?
A) 150 psi
B) 200 psi
C) 250 psi
D) 300 psi
ANSWER: C) 250 psi
(HROB 4.1.7)
FIRE FLOOR / PUMP DISCHARGE PRESSURE
1 - 10 = 150 psi 61 - 70 = 450 psi
11 - 20 = 200 psi 71 - 80 = 500 psi
(21 - 30 = 250 psi) * 81 - 90 = 550 psi

As the Officer of a Midtown Engine Company, you know the responsibility of starting a HROBs fire pumps rests with the building engineers, however if the engineer has been assigned to a different task by the IC or is not present, FDNY units will start and manage the fire pumps. Which is the most correct procedure when operating the buildings fire pumps?
A) Locate the bypass valve on the discharge side of the fire pump. The discharge side can be readily identified by examining the gauges. The discharge gauge is calibrated for higher pressures than the inlet gauge.
B) The bypass valve should be in the closed position (Stem Out). Some engineers keep them closed for test purposes, so they must be checked by the ECC assigned to operate the pumps. If they are found to be closed, they should be opened by turning in a clockwise direction.
C) Some systems are quite complex and the bypass valve is not readily visible. If such a situation is present, it is not permissible to start the pump as ordered without checking the bypass valve.
D) The efficiency of the pump will be affected if the bypass is open. A loss of 45% can be expected in an 8” riser and a loss of 25% can be expected in a 6” riser with the bypass open.
ANSWER: A) Locate the bypass valve on the discharge side of the fire pump. The discharge side can be readily identified by examining the gauges. The discharge gauge is calibrated for higher pressures than the inlet gauge.
B - The bypass valve should be in the closed position (STEM IN). Some engineers keep them OPEN for test purposes, so they must be checked by the ECC assigned to operate the pumps. If they are found to be OPEN, they should be CLOSED by turning in a clockwise direction.
C - Some systems are quite complex and the bypass valve is not readily discernible. If such a situation is present, IT IS PERMISSIBLE to start pump as ordered without checking bypass valve. Notify the engineer upon his/her arrival of this and any other actions taken.
D - The efficiency of the pump will be affected if the bypass is open. A loss of TWENTY FIVE (25%) can be expected in an 8” riser and a loss of FORTY FIVE (45%) can be expected in a 6” riser with the bypass open.
