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.
