Basic Pumping Ops

Question 1

1.5
The Volume position is to be utilized as a standard operating procedure. ALL FDNY pumpers are to be maintained in Volume setting unless_____?

Answer 1

Upon arrival at the scene of an operation, head pressures must be overcome.
(standpipe operations)

Question 2

Lowest RPM that an apparatus is capable of achieving.

Answer 2

Engine Idle

Question 3

Pump Idle Pressure =

Answer 3

The pressure the pump pressure gauge will read when the apparatus is in its lowest RPM

Question 4

Pump Idle Pressure ALWAYS =_______+______?

Answer 4

the pressure the pumps provide at its lowest RPMs (around 55 psi in volume or around 110 psi in pressure) + water intake receives from a water source.
ex: hydrant pressure of 50 psi plus idle pressure in volume 55 psi will equal a pump idle pressure of 105psi

Question 5

The Pro Pressure Governor operates in two modes what are they?

Answer 5

1) Pressure Mode- in this mode the PPG will automatically maintain the discharge pressure set in the LED display

2) RPM Mode- will maintain engine RPMs set in the LED display.
However, WILL NOT automatically compensate for any changes in discharge pressure.

Question 6

True or False
In emergencies, RPM mode is used as a backup in the event that the pressure Mode malfunctions. It can maintain adequate pressure and all handlines will operate the same regardless.

Answer 6

False.
In emergencies it is used as a backup however, if this should occur, ANY hoselines in operation should not advance and should back out to an area of safe refuge.
FDNY uses the PPG in pressure mode only

Question 7

Residual pressure indicates what?

Answer 7

Ramaining capability a hydrant has to supply water INDICATED ON THE INTAKE PRESSURE GAUGE, ONCE WATER IS FLOWING.

Question 8

Flowmeters measure the rate water will flow in GPMs but only when_____

Answer 8

Water is flowing

Question 9

The Officer calls for more water in an 1 3/4” hand line, the ECC notes a flowmeter reading of 110 gpm. This indicates the possibility of _______?

Answer 9

Kinks

Question 10

Officer reports no water at the nozzle of an 1 3/4” hand line or decrease in pressure at the nozzle and the ECC notes a flowmeter reading of 230 gpm. This indicates:

Answer 10

Possibility that there could be a burst length

Question 11

To flush a hydrant when testing it, you must open it fully. True or False?

Answer 11

False.
DO NOT OPEN FULLY.
*let the gentle water flow push out any debris without forcing it up into the barrel.

Question 12

What two hydrant connections are suggested for 1st to arrive engines on the 1st alarm?

Answer 12

10’ small, OR the 35’ soft hydrant connection SHOULD be used

Question 13

When other than 1st to arrive on the 1st alarm what hydrant connections should be used?

Answer 13

10' small suction
10' hard suction
35' soft
*this says SHOULD not MUST.
*NOTICE 3 1/2" IS NOT SUGGESTED FOR ANY 1ST DUE UNITS OR 2ND ALARM UNITS.

Question 14

How should second alarm or greater engine companies connect to hydrants?

Answer 14

10’ hard suction should be used

Question 15

T or F

An Engine Company drafting can use any means available to get water.

Answer 15

FALSE

• *MUST USE 10’ HARD SUCTION
• *ONLY MUST

Question 16

T or F

An Engine Company drafting can use any means available to get water.

Answer 16

FATLSE

• *MUST USE 10’ HARD SUCTION
• *ONLY MUST

Question 17

What should the initial supply line be for in-line pumping operations?

Answer 17

3 1/2” hose

Question 18

When residual pressure drops below____psi on the intake pressure gauge, augmentation will be required.

Answer 18

BELOW 15 psi- residual pressure

Question 19

What shall be done if the Pro Pressure Governor malfunctions?

Answer 19

The apparatus shall be placed OOS.

Question 20

What are the steps for getting a single handline into operation using hydrant water?

Answer 20

4 P’s

1) Once water is entering the apparatus, engage pumps
2) Prime the pumps
3) Depress the Preset Button
4) Determine pressure required
5) Slowly open the discharge outlet until the desired pressure is reached.
* *the PPG will adjust engine speed to maintain indicated pump pressure.

Question 21

What hydrant connections should the supply pumper use in a Water Relay?

Answer 21

10’ or 35’ connection

Evolutions 8 3.3

Question 22

Other than in standpipe ops, both the supply and operating pumpers operate in Volume position at ALL water relay operations. True or False?

Answer 22

True
Exception is a pumper being supplied in a standpipe operation still operates in PRESSURE. Supply pumper operates in VOLUME.
