How To Use A Fire Hose Reel: A Technical Guide For Emergency Operation

Fire hose reels are intended for immediate, first-aid suppression of Class A fires involving solid combustibles such as paper, wood, and textiles. Successful deployment requires rapid extraction of the hose length to the fire site followed by the immediate activation of the water supply valve, ensuring the nozzle is set to the correct flow pattern before engaging the flames from a safe distance.

Pre-Operation Assessment and Safety Protocols

Before operating a fire hose reel, personnel must conduct a rapid risk assessment to ensure the fire remains within the scope of the equipment's capability. Fire hose reels are strictly prohibited for use on electrical fires due to the conductivity of water, and they should never be used on oil or grease fires, which require specialized foam or powder suppression.

• Essential Safety Prerequisites:
  
  
  • Verify the fire classification is Class A (solid combustibles).
  • Confirm the fire is contained within a manageable area and has not reached the ceiling or spread to high-voltage electrical installations.
  • Ensure an unobstructed path of retreat is maintained at all times.
• Operational Benchmarks:
  
  
  • Standard hose length: Typically 30 meters.
  • Operating pressure: Usually between 2 and 4 bar depending on the building's fire hydrant booster system.
  • Estimated deployment time: Should not exceed 15 to 20 seconds for a trained operator.

Operational Execution: Step-by-Step Deployment

Step 1: Initial Alarm Activation

Before attempting to suppress the fire, sound the building fire alarm. If the facility is equipped with a manual call point, activate it immediately. Never prioritize firefighting over life safety or the evacuation of building occupants.

Step 2: Unwinding the Hose

Approach the reel and ensure the nozzle is in the closed position. Grasp the nozzle firmly and pull the hose from the reel, walking toward the fire. Do not attempt to use the hose while it is still coiled on the reel, as the water pressure will be restricted, causing the hose to kink and fail. Ensure you have pulled enough length to reach the base of the fire comfortably.

Step 3: Engaging the Water Supply

Locate the gate valve or the stopcock usually mounted on the wall adjacent to the reel. Turn the valve handle fully in an anti-clockwise direction to open the water flow. You will hear the water travel through the reel and into the hose line.

Warning: Do not attempt to open the water valve until the hose is fully unwound to the base of the fire; attempting to move the hose while it is pressurized is physically taxing and increases the risk of kinking.

Step 4: Nozzle Adjustment and Suppression

Point the nozzle toward the base of the fire. Most fire hose reel nozzles are adjustable between a jet (straight stream) and a spray (fog pattern). For initial suppression of solid fuel fires, a spray pattern is often preferred to cover a wider area and cool the fuel source. Direct the stream at the base of the flames, moving the nozzle in a sweeping motion to smother the combustion.

Step 5: Monitoring and Containment

Maintain a safe distance from the fire. As the flames subside, adjust the nozzle to a jet pattern to reach deep-seated embers. Continue until the material is thoroughly soaked and the fire is extinguished. Monitor the area for signs of re-ignition until professional fire services arrive to assume control of the scene.

Technical Specifications and Performance Parameters

The efficiency of a fire hose reel is determined by its ability to maintain constant flow pressure over the entire length of the hose. The following table outlines the technical specifications typically associated with fire-rated equipment meeting international standards like EN 671 or equivalent local building codes.

Troubleshooting Common Field Failures

Even with proper maintenance, mechanical or human-error-related failures can occur during an emergency. Understanding these failure points is vital for quick resolution.

• Nozzle Fails to Discharge Water:
  
  
  • Root Cause: The supply gate valve is closed or the hose is severely kinked.
  • Actionable Fix: Verify the gate valve is turned fully counter-clockwise and trace the hose line back to the reel to clear any physical obstructions or sharp bends.
• Insufficient Water Pressure:
  
  
  • Root Cause: The hose is not fully unwound, restricting flow through the reel hub.
  • Actionable Fix: Ensure the hose is pulled out entirely. If pressure remains low, check for leaks at the drum connection or ensure other hose reels in the building are not simultaneously depleting the local system pressure.
• Nozzle Jammed:
  
  
  • Root Cause: Mineral build-up or debris in the nozzle head from infrequent testing.
  • Actionable Fix: Attempt to rotate the nozzle head forcefully to break the seal. If it remains fixed, prioritize evacuation rather than attempting to repair the equipment during an active fire.

Frequently Asked Questions

Can I use a fire hose reel on an electrical fire?

No, never use a water-based fire hose reel on an electrical fire. Water is an excellent conductor of electricity, and using it risks electrocuting the operator or causing a short circuit that can worsen the fire; use a CO2 or dry chemical extinguisher instead.

How often should fire hose reels be serviced?

Under international safety standards, fire hose reels require a formal inspection and testing by a certified technician at least once every 12 months. This ensures the valves, hose integrity, and water pressure meet the regulatory requirements for the facility.

What should I do if the fire is too large to handle?

If the fire is spreading rapidly, producing heavy smoke, or has moved beyond the immediate vicinity of the starting material, stop firefighting efforts immediately. Prioritize your personal safety, evacuate the building through the nearest fire exit, and await the arrival of the fire department.

Are fire hose reels only for Class A fires?

Yes, fire hose reels are specifically designed for Class A fires (wood, paper, textiles). They are ineffective and potentially dangerous when used on flammable liquid (Class B) or electrical (Class E) fires.
