[B304.2 Sprinkler Systems and Fire Pumps]

Sprinklers are more effective at putting water on the fire than:

Manual firefighting

2
[B304.2 Sprinkler Systems and Fire Pumps]

What is the best system available to quickly control fires in buildings?

Automatic Sprinklers

3
[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

4
[B304.2 Sprinkler Systems and Fire Pumps]

Fires in buildings with sprinkler protection will require the fire department to:

Supplement it

5
[B304.2 Sprinkler Systems and Fire Pumps]

A minimum of how many supply lines should be connected to the FDC?

2

6
[B304.2 Sprinkler Systems and Fire Pumps]

Which FDC should be the priority?

Standpipe

7
[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

8
[B304.2 Sprinkler Systems and Fire Pumps]

The pressure to be supplied to the sprinkler system must be equal to the:

Required system pressure

9
[B304.2 Sprinkler Systems and Fire Pumps]

How can you determine the required system pressure at the fire pump?

Look at the discharge gauge 

10
[B304.2 Sprinkler Systems and Fire Pumps]

What is the minimum pressure to be supplied to an FDC?

150 psi

11
[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

12
[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

13
[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

14
[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)

15
[B304.2 Sprinkler Systems and Fire Pumps]

At what psi system pressure should trucks pump to the FDC in tandem?

225 psi

16
[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

17
[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

18
[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

19
[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

20
[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

21
[B304.2 Sprinkler Systems and Fire Pumps]

What are the 4 ways to either find or estimate the required system pressure?

1. Look in CAD

2. Sign at FDC

3. Calculated using the rated pump pressure (on Pump info plate) and the intake pressure

4. 150 psi rule of thumb using the height of the building estimation (+5 psi per floor above the 11th)

22
[B304.2 Sprinkler Systems and Fire Pumps]

What valve should be used to shut down sprinklers to improve visibility?

Section control valves

23
[B304.2 Sprinkler Systems and Fire Pumps]

Who shalll be notified if a system is shut down due to mechanical failures?

Prevention

24
[B304.2 Sprinkler Systems and Fire Pumps]

What sprinkler systems should not be supported by AFD?

Residential sprinklers (1.5 inch inlet)
