What are three common problems that cause water loss?
Kinks, Burst Lengths, and Short Stretching.
FFP ENG CO OPS Ch 12 Sec 1.1

C. Control FF 2nd due
D. All members operating at an incident, both engine and truck
D. All members
FFP ENG CO OPS Ch 12 Sec 2.4
An indication of a __________ is when the engine officer reports there is little or no water and the ECC sees adequate pressure reading and an increased flow showing on the outlet flowmeter with the pumps RPMs increasingly automatically.
A. Kink
B. Burst Length
C. Short stretch
B. burst length
FFP ENG CO OPS Ch 12 Sec 3.2
T or F Once a water loss due to a burst length is confirmed by a member he should transmit an Urgent?
True
FFP ENG CO OPS Ch 12 Sec 3.3
Once the location is verified and after water has been shut down what are two correct ways to correct a burst length?
- If enough hose is available, remove the burst length and reattach the existing couplings.
- Replace the burst length with a new length of hose, when there is not enough existing hose available in the stretch.
This should only be accomplished upon the engine officers orders, after the fire has been confined by closing a door/or members have moved to a safe area of refuge.
