24 hours
Fabric jacketed supply lines (including by-passes and soft suctions) shall be changed ______.
Weekly or more frequently if damp or dirty.
True or False?
Hose shall be kept out of direct sunlight.
True
A physical inspection shall determine if the hose and couplings are free from DEBRIS, CUTS and ABRASIONS, and/or exhibit no evidence of mildew, rot, or damage by chemicals. The interior of the hose at each end shall be visually inspected for any physical signs of DELAMINATION.
Station Commanders needing replacement of hose shall contact ________.
Equipment Engineering Unit at S&M
What is the service life of hose?
10 years
Hose shall be removed from apparatus and reloaded with SUFFICIENT REGULARITY to prevent _______ and ________.
Damage and the setting of permanent folds in the rubber lining.
If the hose leaks or the hose jacket fails inspection, identify the damaged area(s) by?
wrapping the hose with black tape at the location(s) where repairs are needed.
(Send to S&M for repair or replacement)
All lengths of hose of the same _____ shall be tested at the same service test pressure.
Size
The total length of any hose line being tested shall not exceed _____ feet.
300ft
Which hose is tested at 300 PSI?

•2” high-rise, 2-1/2” high-rise pigtail, 3” ladderpipe hose (single jacketed synthetic nitrile rubber lined hose)
•brush hose (single jacketed thermal plastic lined)
What hose is tested at 250 PSI?
4” supply hose (single jacketed synthetic nitrile rubber lined hose)
What hose is tested at 400 PSI?
Double-jacketed rubber lined hose
•1”

Hose Test
The duration of the hose test shall be ______ minutes at the required pressure
5 minutes
The maximum amount of hose per outlet during a hose test shall be ______ feet.
300 ft
To determine if a coupling or collar has slipped during the hose test, what is done before the test starts?
Mark with pen or marker around the hose at the back of each coupling.
After the hose test layout is full of water, all air in each line shall be exhausted by having the nozzle slightly open and?
-raising the discharge end of each line above the highest point of the system.
(All air must be removed from the hose before the nozzle is CLOSED and starting test)
Performing the Hose Test
The pressure shall be raised at a rate not greater than ____ PSI per second until the service test pressure is reached.
15 PSI
While inspecting the test layout for leaks, members shall remain outside of the Test Area.
Members shall never be within _____ ft of the hose.
15’
After five minutes at the service test pressure, the apparatus shall be throttled down to idle, discharge gate(s) slowly closed, pump taken out of gear, engine idled for _____ minutes before shut-down.
5 minutes.
At the conclusion of the test, the Station Commander shall document the test where?
-journal entry in the F-2
-complete and forward the F-129 Annual Hose Test Record.
(One-twenty-nine = Test-a-hose-linej
