Engine Ops

Question 1

What is an indication of kinks?

T or F- increasing pressure and quickly resolve most kinks.

Answer 1

Indication of kinks- good pressure with a reduction in flow at the flow meter

False- do not increase pressure to try to resolve a kink

Question 2

What is a sign of a burst length (at the pump panel)?

Answer 2

Adequate pressure, increased flow, and an increase in RPM’s of the pumps

Question 3

Short stretch

Adding a length to the back of the stretch may be impractical when more then ____ lengths were originally deployed.

Answer 3

More then 4

Question 4

Do you need a special fitting when:

You have short stretch a 1 3/4” and are going to add a length of 1 3/4”?

You have short stretched a 2 1/2” and will be adding a 2 1/2” length?

Answer 4

1 3/4” to 1 3/4” no fitting needed

2 1/2” to 2 1/2” you will need a 1 1/2” to 2 1/2” increaser

Question 5

Buildings that require a stretch of more the _#___ lengths from the standpipe should be entered into CIDS for that reason.

Answer 5

More then 3 lengths

Question 6

At some standpipes there will be “occupant use” hose. Who and when can this be stretched?

Answer 6

Ladder or rescue companies can use this line if operating remotely from an engine company and it is used to save lives.

Question 7

What are the following standpipe Siamese colors for?

1) green
2) yellow
3) red
4) silver

Answer 7

Green- automatic sprinkler
Yellow- combo standpipe and sprinkler
Red- standpipe
Silver- non-automatic sprinkler or perforated pipe

Question 8

Standpipes should alway be supplied by ____ hose (size)? Whenever possible how many engines should supply a standpipe

Answer 8

Supply with 3 1/2” hose

When possible 2 engines should supply it

Question 9

A second engine is going to supply the standpipe system. Where should they hook up?

Answer 9

At a floor outlet, they should not connect to the Siamese the 1st engine is using

Question 10

T or F
As a general rule, one engine should be supplying the standpipe system for each line stretched. 3 lines stretched = 3 engines supplying

Answer 10

True

Question 11

T or F
If the 1st engine is supplying both standpipe and sprinkler systems, the second and third engine MUST stretch additional lines to augment BOTH systems.

Answer 11

True

Question 12

What is in a standpipe kit?

Answer 12

2 1/2” controlling nozzle
Pipe wrench
Spinners
In line pressure gauge
Door chocks
Special adapters

Question 13

At a standpipe operation with water flowing what should the pressure be at the outlet for 3 lengths? 4 lengths?

Answer 13

3 lengths 70psi

4 lengths 80psi

Question 14

What is considered high pressure pumping?

A high pressure engine ( two stage) can pump up to what pressure?

Answer 14

High pressure pumping is above 250psi

A high pressure engine can pump up to 600psi

Question 15

A 3rd stage engine can pump a maximum pressure of what?

Answer 15

500 gpm at 700psi

Question 16

High pressure supply hose has its couplings pained what color?

Answer 16

White

Question 17

Whenever possible an engine supplying high pressure should be within __#__ length(s) of the fire department connection being supplied. No more then __#__ lengths of high pressure hose should be stretched to a fire department connection.

Answer 17

1 length is ideal, no more then 2 lengths.

Question 18

When operating in high pressure how big is the safety zone?

Answer 18

50ft all around the engine

Question 19

3rd stage pumpers are proffered when pumping over pressures over ___psi. Who can order the use of a 3rd stage pumper?

Answer 19

500psi

An IC of the rank battalion chief or higher

Question 20

T or F
When using a high pressure, the supply lines need to be tethered and pressure will be increased slowly to avoid damaging the standpipe system.

Answer 20

True

Question 21

When is an air pressure standpipe required?

Answer 21

The construction of buildings over 75ft and the destruction of buildings with an existing standpipe.

Question 22

An air pressurized standpipe system is required to have as many relief valves as needed to bleed the system in no more then __#__ minutes

Answer 22

No more then 3 minutes

Question 23

A sprinkler system should always be supplied by what size hose?

Answer 23

3 1/2”

Question 24

Pump discharge pressure for supplying a sprinkler system should start at what psi?

Answer 24

Start at 150psi
