Study Notes
Hose Operations and Maintenance Procedures
- Follow procedures in Vol. 3, 6/6-01.01, Page 51 for accurate journal entries in F-2 and F-128.
- Ensure all hose coupled on apparatus is secure and orderly.
- Inspect hose gaskets; replace any that have deteriorated.
Specific Hose Types
- Small hard suction hoses assigned to tanks must not endure pressure.
- When "picking up" hose, ensure it’s ready for immediate use and minimize water damage when breaking lines indoors.
Safety Measures for Hose Lines
- Shut nozzles off after attaching to hose lines and ceasing flow.
- Avoid charging hose lines from heights until secured; use ladders or straps for safety.
- Drain water at street level before lowering hoses from heights.
- Prohibit unnecessary water direction at persons or properties.
Testing and Maintenance of Hoses
- Annual testing required for hard suction hoses during pump tests; new or repaired hoses tested post-receipt.
- Testing frequency is maximum 12 months; unreliable hoses should be tested immediately.
- Test pressure varies:
- 300 P.S.I for rubber lined double jacketed hoses (except one-inch), and synthetic nitrile hoses.
- 400 P.S.I for one-inch double jacketed hose.
- Follow N.F.P.A. 1962 standards; service test pressure must be marked on hoses post-July 1987, but the Manual of Operation takes precedence if differing pressures are noted.
Testing Protocols
- Duration of tests should be five minutes at the specified pressure.
- Maximum hose length for testing is 300 feet from one outlet.
- Limit horizontal movement of large streams (2-1/2" or larger hoses) from an aerial ladder to 15 degrees to maintain stability.
Cleaning and Repair Procedures
- Clean dirty hoses using only clear, cold water; consult with Supply and Maintenance Division for substances that resist cleaning.
- Repairs handled by Supply and Maintenance; personnel must not attempt repairs on hose threads or swivels.
- Damaged hoses should be clean, dry, rolled, and properly tagged with repair needs for handling.
- Small burns do not classify as damaged; ensure to test hoses per protocols before repair requests.
Hose Marking and Tagging
- Indicate damage with black tape and roll hose with the female coupling as the core; male coupling as core only if the female needs repair.
- Attach F-175 tag detailing the issue; clarity is essential (e.g., hole 10' from male coupling).
