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.

- 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.
