B304.2 Sprinkler Systems and Fire Pumps (01-01-2014) Flashcards
[B304.2 Sprinkler Systems and Fire Pumps]
Sprinklers are more effective at putting water on the fire than:
Manual firefighting
[B304.2 Sprinkler Systems and Fire Pumps]
What is the best system available to quickly control fires in buildings?
Automatic Sprinklers
[B304.2 Sprinkler Systems and Fire Pumps]
What should be visually checked any time the presence of significant fire is established in a high-rise?
Fire pump and Sprinkler system
[B304.2 Sprinkler Systems and Fire Pumps]
Fires in buildings with sprinkler protection will require the fire department to:
Supplement it
[B304.2 Sprinkler Systems and Fire Pumps]
A minimum of how many supply lines should be connected to the FDC?
2
[B304.2 Sprinkler Systems and Fire Pumps]
Which FDC should be the priority?
Standpipe
[B304.2 Sprinkler Systems and Fire Pumps]
If there are standpipe and sprinkler system FDCs, where should the initial 2 connections be made?
1 on each
[B304.2 Sprinkler Systems and Fire Pumps]
The pressure to be supplied to the sprinkler system must be equal to the:
Required system pressure
[B304.2 Sprinkler Systems and Fire Pumps]
How can you determine the required system pressure at the fire pump?
Look at the discharge gauge
[B304.2 Sprinkler Systems and Fire Pumps]
What is the minimum pressure to be supplied to an FDC?
150 psi
[B304.2 Sprinkler Systems and Fire Pumps]
Where can you look to find a number of different building’s system pressure requirements in Austin?
CAD
[B304.2 Sprinkler Systems and Fire Pumps]
If the building does not have a fire pump or it is not working and the system pressure cannot be determined, what can be used to estimate the required system pressure
The height of the building
[B304.2 Sprinkler Systems and Fire Pumps]
When estimating the system pressure based on the height of the building, what is considered adequate pressure for buildings with 10 floors or less?
150 psi
[B304.2 Sprinkler Systems and Fire Pumps]
When estimating the system pressure based on the height of the building, what is the formula for buildings over 10 floors?
150 + (5 psi for every floor over from the 11th up, or the highest floor served by the FDC)
[B304.2 Sprinkler Systems and Fire Pumps]
At what psi system pressure should trucks pump to the FDC in tandem?
225 psi
[B304.2 Sprinkler Systems and Fire Pumps]
When should sprinkler systems be shut down?
After the fire has been extinguished by the authority of Command
[B304.2 Sprinkler Systems and Fire Pumps]
At any structure fire in a building equipped with a fire pump and sprinkler system, Command should dispatch a team of at least 2 firefighters to:
Locate the main valve and ensure it is open
[B304.2 Sprinkler Systems and Fire Pumps]
When should the main valve not be opened?
When there is an out of service sign on it
[B304.2 Sprinkler Systems and Fire Pumps]
If the sprinklers are flowing water, but the pump is not running, what should be done?
Try starting the pump by putting the lever in the manual position
[B304.2 Sprinkler Systems and Fire Pumps]
What should be done to avoid the possibility of the pump shutting down?
Put the control lever into the manual position
[B304.2 Sprinkler Systems and Fire Pumps]
What are the 4 ways to either find or estimate the required system pressure?
- Look in CAD
- Sign at FDC
- Calculated using the rated pump pressure (on Pump info plate) and the intake pressure
- 150 psi rule of thumb using the height of the building estimation (+5 psi per floor above the 11th)
[B304.2 Sprinkler Systems and Fire Pumps]
What valve should be used to shut down sprinklers to improve visibility?
Section control valves
[B304.2 Sprinkler Systems and Fire Pumps]
Who shalll be notified if a system is shut down due to mechanical failures?
Prevention
[B304.2 Sprinkler Systems and Fire Pumps]
What sprinkler systems should not be supported by AFD?
Residential sprinklers (1.5 inch inlet)
