TB 63 Supplementing High Rise Fire Pumps

Question 1

System pressure equals

Answer 1

head pressure plus friction loss in the standpipe plus pressure required at the highest outlet

Question 2

Quickest way to identity system pressure.

Answer 2

Locate the fire department connection sign, a plaque mounted near the FDC

Question 3

FDC sign provides the system pressure and may also include

Answer 3

area of building served and address of building.

Question 4

Alternate method to determine SP would be to consult the ______or

Answer 4

building engineer or to view the discharge gauge of the buildings fire pump while the pump is running.

Question 5

Estimating SP can be calculated by

Answer 5

multiplying the number of floors by 5 then adding the constant of 150 psi.

Question 6

The constant of 150 PSI is derived by

Answer 6

Question 11

If pumping over _____ , strap the lines together using ladder straps on ______

Answer 11

300 PSI / each side of each coupling and midway between each coupling. Load the 2 1/2” lines before strappig.

Question 12

Another apparauts shall spot to the hydrant/4 way and pump half the system pressure to the apparatus supplying the FDCs if

Answer 12

the high rise is over 20 stories or the system pressure at the FDC is over 250 psi

Question 13

If there is fire, pump into the system ____

Answer 13

100 psi below the system pressure.

Question 14

To determine if water is flowing or not?

Answer 14

Feather the discharge gate, if the gate resists closing and or there is a drop on the discharge gauge. water is flowing.

Question 15

If there is an actual fire,

Answer 15

duplicate the lay into the other two inlets of the FDC utilizing a separate source of water.

Question 16

At the scene of a high rise fire, danger from ____

Answer 16

falling glass and debris is a genuine concern

Question 17

Safety Considerations: Have truck spot there aerial to cover both the panel and the FDCs. Once spotted ____

Answer 17

lay salvage covers, folded to a quarter of their width, on the rungs from the pedestal to the top of the aerials

Question 18

Safety Considerations: Spotting a second apparatus next to your engine and using a ______

Answer 18

pike pole and salvage create a roof over the panel.

Question 19

Safety Considerations: Draping ______ over the offside running board to the ground to protect the legs from horizontal spread of flying glass shards
