Study Notes

Hard Suction and Hose Covers

Hard suction must be secured to the apparatus when not in use to prevent movement during transport.
Hard suction hose cannot be connected to a pressurized water source at any time.
All hose beds and storage areas on PBCFR apparatus require a cover and securement system per NFPA 1901 standards to prevent unintentional deployment.

General Care of Fire Hose

Proper maintenance and care of fire hoses are essential for performance and longevity.
Clean hoses after each use; if contaminated, wash with warm water and mild detergent.
Avoid dragging hoses over rough surfaces, placing them near exhausts, or allowing vehicles to pass over them.

Hose Maintenance Practices

Use hose ramps and chafing blocks to prevent damage from abrasion and vibrations.
Open and close nozzles and discharge gates slowly to avoid water hammer effects.
Ensure hoses are fully charged with water and all air is expelled to prevent hose whip during bursts.

Testing Procedures

Pressure testing involves applying 45 psi (± 5 psi) and checking for leaks at each coupling.
Mark hoses with a permanent marker at the back of the coupling for monitoring slippage during tests.
Service test pressures vary:
- 5” fire hoses: 200 psi max
- 3” fire hoses: 300 or 400 psi depending on age
- 2½” Hi-Combat: 300 psi
- 2½” Key Tru-ID: 400 psi
- 1¾” fire hoses: 300 psi
- 1½” forestry hoses: 300 psi
- Booster Reel hoses: 250 psi

Test Conditions and Cautions

Pressure must be increased slowly at no more than 15 psi per second.
Hoses should maintain test pressure for 3 minutes.
Water must circulate through the pump during testing to avoid damage; open Tank Fill valve just enough to move water without exceeding 100 psi.
Inspect hoses for leaks while under test pressure and keep personnel a safe distance from the hose lines to avoid injury from ruptures.
