Regularity
A what shall determine if the hose and coupling are free from debris, cuts, and abrasions and/or exhibit no evidence of mildew, rot, or damage by chemicals?
Physical inspection
The interior of the hose at each end shall be visually inspected for any physical signs of what?
Delamination
Who identifies hose that is in need of replacement due to excessive wear or the 10 year service life has been reached and shall contact equipment engineering unit at S and M division for assistance?
Station commanders
All hose shall be cleaned when?
After each use
Dirty hose shall be washed with what?
Clear cold water
Heavily soiled hose may be washed using a what percentage solution of concentrated liquid soap?
5% to 10%
Who that has identified hose which is contaminated and cannot be cleaned with cold water shall contact S and M, equipment engineering unit personnel for instruction?
Station commanders
Hose shall be positioned to minimize what?
Mechanical damage and/or heat exposure
Vehicles should what over fire hose whenever possible?
Avoid driving over
Nozzles and valves shall be opened and closed slowly to prevent surges and what which can burst hose and cause injury to personnel and/or damage the fire pump?
Water hammer
All hose shall be drained and throughly dried before being placed into what?
Service
If the hose leaks or the hose jacket fails inspection, identify the damaged areas by wrapping the hose with what the the location(s) where repairs are needed?
Black tape
If the couplings fail or are defective, the hose shall immediately be what and sent to S and M?
Taken out of service
All lengths of hose of the same size shall be tested at the same what?
Service test pressure
Total length of any hose line being tested shall not exceed how many feet?
300 feet
The total lay out of hose shall be straight without any what?
Kinks or twists
Hose testing should not be performed during incidents, post incidents or training unless who can ensure that all safety provisions can be adhered to and can be monitored for hose failure and clear of civilians and vehicles?
Company commanders
Safety precautions are vital to hose testing, a hose line may burst under pressure due to what and can be hazardous?
Trapped air and/or pump volume
Double jacketed rubber lined hose such as bypasses and soft suctions shall be tested at what psi?
300 psi
Single jacketed synthetic nitrile rubber lined hose such as 2 high rise hose, 2 1/2” pig tail and 3” ladder pipe hose shall be tested at what psi?
300 psi
Single jacketed synthetic nitrile rubber lined 4” supply hose shall be tested at what psi?
250 psi
Double jacketed rubber lined hose such as 1”, 1 1/2”, 1 3/4”, and 2 1/2” shall be tested at what psi?
400 psi
Single jacketed thermal plastic lined hose (brush hose) shall be tested at what psi?
300 psi
Due to the lightweight construction of brush hose it is recommended that the hose be tested on what?
Grass or light fuel bed surfaces
Dragging brush hose one what will cause damage to the outer jacket leading to leaks in the hose?
Concrete or asphalt
The duration of hose testing is how many minutes at required pressure?
5 minutes
The length of each hose line is how many feet per outlet?
300 feet
When laying out the hose from the apparatus discharge, attach a what to the end?
Shut off butt and appropriate nozzle
Each hose shall be marked with what around the full circumference at the end of the hose at the back of coupling?
Pen or marker
Marking the hose at the back of each coupling will deterring after the hose has been tested or drained if the coupling or collar has what during test?
Slipped
The hose shall be attached to which side of the engine?
Offside
What shall not be used while performing the test of the hose?
Appliances such as gated wyes
With the discharge gate and nozzle open slightly, the pressure shall be gradually raised to what psi (+-)?
45 psi
Depending on LAFD apparatus, consider pumping the hose in what position at the panel?
Volume
Open the tank to pump slightly and open the tank fill valve to circulate water, if equipped utilize what valve to avoid the building up of excessive heat within the pump casing?
Recirculating valve
After hose is laid out and full out water, all air in each line shall be exhausted by raising the discharge end of each line above what point of the system?
Highest point
All air must be removed from the hose score the nozzle is what and the pressure is raised to the appropriate test pressure?
Closed
When using manifold gates, the gates should be opened how much and the isolation gates on the pump panel should be open how much?
Manifold gate fully, isolation gate slightly cracked opened and locked
The pressure shall be raised at a rate not greater than how many psi per second until the service test pressure is reached and maintained for 5 minutes?
15 psi
While inspecting the test layout for leaks, members shall remain outside of the test area and the front end of the hose of how many feet and never straddle a hose in the test area?
15 feet
If during the test a section of hose is leaking or bursts the service test shall be what?
Terminated immediately, defective hose removed
After the 5 minute test, the apparatus shall be throttled down to idle, discharged gates slowly closed and pump taken out of gear, allow the engine to idle for how many minutes before shut down?
5 minutes
Who shall make a journal entry into the F-2 and complete and forward the F-129 annual hose test record at the conclusion of the test?
Station commander
