Flashcards in B304.2 Sprinkler Systems and Fire Pumps (01-01-2014) Deck (24):
1

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

Manual firefighting

2

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

Automatic Sprinklers

3

What should be visually checked any time the presence of significant fire is established in a high-rise?

Fire pump and Sprinkler system

4

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

Supplement it

5

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

2

6

Which FDC should be the priority?

Standpipe

7

If there are standpipe and sprinkler system FDCs, where should the initial 2 connections be made?

1 on each

8

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

Required system pressure

9

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

Look at the discharge gauge 

10

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

150 psi

11

Where can you look to find a number of different building's system pressure requirements in Austin?

CAD

12

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

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

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

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

225 psi

16

When should sprinkler systems be shut down?

After the fire has been extinguished by the authority of Command

17

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

When should the main valve not be opened?

When there is an out of service sign on it

19

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

What should be done to avoid the possibility of the pump shutting down?

Put the control lever into the manual position

21

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

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

Section control valves

23

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

Prevention

24

What sprinkler systems should not be supported by AFD?

Residential sprinklers (1.5 inch inlet)
