Flashcards in High Pressure Pumping Deck (23):
What is considered high pressure pumping?
Operating at a discharge pressure over 250 psi
Conventional engines should not operate over 250 psi unless
Emergency conditions exist and ordered by the IC and you must use utility rope to secure supply line at bldg connection and apparatus.
At what floor in a high rise BLDG would you have use high pressure pumping?
At the 31st floor you should be at 300 PSI
When going to use high pressure pumping if possible the apparatus should be how many supply lengths away from the FD connection?
When your going to use your rig for high pressure pumping you should be no more than how many supply lengths away from the FD connection
Can you supply 2 high pressure supply lines to a single Siamese?
No just one
When using the high pressure hoses they should be tethered and a safety zone established prior to operations. What is the safety zone?
Maintain 50 ft around working engine and supply hose
How many ECC's are needed to operate pumper for high pressure ops?
2 ECCS one to operate pumps and the other to use HT
When using high pressure pumps and charging the stand pipe can we use the Preset on the rig
No increase pumps slowly
If other than first due to a fire in a high rise high pressure engine and third stage engines shall be positioned where?
At a hydrant in proximity to FD connection
Pressure over what requires 3rd stage pumping?
Which engine is the preferred choice for discharge pressure over 500 psi
3 stage pumper
High pressure pumpers can pump at discharge pressures over _____ psi and up to ______ psi.
3rd stage engines can supply a maximum of _____ GPM up to ____ psi.
At what floor would 3rd stage engines RECOMENDED?
At what floor would a 3rd stage engine be mandatory?
All unused gates and outlets on a pumper going to be used for high pressure pumping must be?
Who shall assist in keeping persons out of the safety zone when high pressure pumping is going on?
Other ECC of non pumping engines
Who will be designated high pressure pumping supervisor?
A battalion chief
When your going to be high pressure pumping should the ECC use the preset button for pressure?
No should not be used when charging the standpipe system
When more than one engine co supplies the standpipe system should communicate and coordinate what
They operate at the SAME discharge pressure.
How many high pressure supply lines can be connected to a Siamese connection?
