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.
