Answer 10

150 psi

Question 11

[B304.2 Sprinkler Systems and Fire Pumps]

Answer 11

CAD

Question 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

Answer 12

The height of the building

Question 13

[B304.2 Sprinkler Systems and Fire Pumps]

Answer 13

150 psi

Question 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?

Answer 14

150 + (5 psi for every floor over from the 11th up, or the highest floor served by the FDC)

Question 15

[B304.2 Sprinkler Systems and Fire Pumps]

Answer 15

225 psi

Question 16

[B304.2 Sprinkler Systems and Fire Pumps]

When should sprinkler systems be shut down?

Answer 16

After the fire has been extinguished by the authority of Command

Question 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:

Answer 17

Locate the main valve and ensure it is open

Question 18

[B304.2 Sprinkler Systems and Fire Pumps]

When should the main valve not be opened?

Answer 18

When there is an out of service sign on it

Question 19

[B304.2 Sprinkler Systems and Fire Pumps]

If the sprinklers are flowing water, but the pump is not running, what should be done?

Answer 19

Try starting the pump by putting the lever in the manual position

Question 20

[B304.2 Sprinkler Systems and Fire Pumps]

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

Answer 20

Put the control lever into the manual position

Question 21

[B304.2 Sprinkler Systems and Fire Pumps]

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

Answer 21

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)
