Evolution 1A...IN LINE PUMPING

Question 1

IN LINE PUMPING…

Answer 1

pumper reaches hydrant BEFORE fire

4 FF Engine:
hydrant FF =control
hose ff= back up

5 ff engine co:
hydrant ff=control
hose ff= door

Question 2

Pumper stops so that rear step is opposite hydrant…

Answer 2

Hydrant FF equipped with a hydrant wrench and 2 1/2” gate, test the hydrant

Question 3

After the hydrant is deemed serviceable, the ___FF will KEY THE HYDRANT by pulling sufficient 3 1/2” hose from the hose bed and take turn around the hydrant?

Answer 3

HOSE FF (NOT HYDRANT FF)

-HOSE FF then mounts the backstop and prepares to use signal buzzer

Question 4

Hydrant FF will?

Answer 4

-maintain the key
-connect the 3 1/2” hose to the 4 1/2:” outlet
-IF TIME PERMITS, connect the 2 1/2” gate
WAIT for ECC notification, before opening hydrant

Question 5

At SLOW rate of speed, playing out hose, the pumper process to the vicinity of the fire building, NOT to impeded the positioning of a ladder company…

Answer 5

HOSE FF rides the rear step and monitors the playing out of hose

Question 6

Supplying BOOSTER WATER upon OFFICERS ORDERS shall be give priority over hooking up the in line supply line….

Answer 6

Initial handline stretch will be controlled by Door (5 FF engine) or ECC (4 FF ENGINE) until relieved by control FF

Question 7

Booster water is used…?

Answer 7

NOTIFY Engine Officer and notify Engine OFFICER she n back to hydrant water

Question 8

Notes for ILP:

Answer 8

• hydrant must be on 6” or LARGER main…during water alert, ILP shall not be used UNLESS absolutely necessary
• 3 1/2” supply line
• NOT more than 6 lengths of hose shall be used in the initial supply line
• when INTAKE PRESSURE DROPS BELOW 15 PSI, the pump operator shall have his intake supply augmented
• necessary fittings to connect to a hydrant shall be pre connected to 3 1/2” supply hose on the pumper(DON’T CONFUSE WITH SUPPLY LINE NOT BEING PRECONNECTED)
• Supply SHOULD NOT be pre connected to pumper
• Generally max of 3 lengths of 3 1/2’’ supply line should be HAND STRETCHED back to hydrant
• time permitting- 2 1/2” gate connected

Question 9

ECC of the ILP should have water supply augmented when the INTAKE pressure drops below 15 PSI.

WHEN INTAKE IS low (30-40 psi), residual pressure may not be capable of sustaining 2 lines

Answer 9

Following signals used form back step buzzer:
ONE BUZZER- EMERGENCY STOP
TWO BUZZER- HOSE FF in position, pumper to proceed
THREE BUZZER TONES-area to rear of pumper is clear for backing up operations and under proper supervision

Question 10

The capacity of a hydrant is a MAJOR FACTOR in in line pumping operations …capacity is based on ?

Answer 10

size of main
location within the system
