TB 63, supplementing hi rise fire pumps Flashcards
in the event of fire pump failure, the quickest and most reliale way to identify and determine the system pressure is?
locate the fire department conception sign which provides the stem pressure
the member responsible for supplying the water system at a hi rise building is?
first arriving 200 series engineer
the engineer supplying the water system at a hi rise fire should do all of the following…
la hydrant to fire
remove all plugs from the FDC inlets
connect 2 2 1/2” lines from the apparatus to the FDC
the purpose of supplementing fire pumps at hi rise buildings is?
designed a s a back up in case of fire pump failure
buildings with a fire pump supplying the standpipe stystem. hi rise buildings affected are?
1960-1975 higher than 150’
75-150’ retrofitted with a fire pump
built after 1974
if a high rise building is over ? or the system pressure at the FDC is over? psi, another apparatus shall spot to the hydrant/4 way valve and pump half the system pressure to the apparatus supplying the FDC
20 stories;
250
if there is a fire, pump into the system ? the system pressure as indicated to fht FDC sign or on the calculated estimate. this should be below the ON/OFF pressure settings on the fire pump allowing the pump to perform its designed function
100 psi below
At an actual fire emergency at a 35 story high rise building and a FDC system pressure gauge is not provided, the engineer assigned to supply the fire dept. connections shall pump approximately how many psi?
225 psi
