Daily Inspection and Monitoring of Remote Water Supply Hoses

     Remote water supply hoses are the "lifeline" of firefighting operations, and their performance and stability directly impact firefighting and rescue efficiency. To ensure hoses are fully operational at critical moments, Sanjiang Fire Department reminds you: daily inspections and dynamic monitoring are essential.
Appearance Inspection: The subtleties reveal the truth.
Daily inspections should focus on the Fire Hydrant Hose's surface condition:
Damage Inspection: Use a strong flashlight to scan the entire length of the hose, inspecting for cracks, bulges, or signs of wear. For rubber hoses, be wary of aging and cracking; for metal hoses, check for cracks in the welds.
Special Inspection of Joints: Joints are a high-risk area for leaks. Use a wrench to confirm that threaded connections are tight and that the seals are intact and free of deformation. Water stains or rust on the joints may indicate micro-leakage.
Environmental Assessment: Observe whether the hose has come into contact with sharp objects, corrosive chemicals, or high-temperature equipment. Remove any entangled debris promptly to prevent damage. Pressure and Flow Monitoring: Data-Based Risk Warning

Build a real-time monitoring system using pressure gauges and flow meters:

Parameter Baseline Establishment: Record the hose's normal pressure range (e.g., 0.8-1.2 MPa) and flow rate (e.g., 50 L/s) under rated operating conditions as a benchmark for subsequent comparisons.

Abnormal Response Mechanism: If the pressure consistently drops by 20% below the baseline value or the flow rate drops by more than 15%, this may indicate an internal blockage or leak. Immediately shut down the unit for inspection to avoid escalating the incident by operating with the problem.

Trend Analysis Application: Continuously record 30 days of operating data and plot a pressure-flow curve to proactively identify progressive failures such as pipe wall scaling and localized collapse.

Sanjiang Fire Department Reminder: A "one pipe, one file" management system must be established for the maintenance of remote water supply hoses. After each inspection, an electronic log should be completed, recording the damage location, repair history, and replacements.
