Fire hose reels (fire hose reels) are mainly used in the early stages of a fire, especially when the fire is small and has not yet spread.
Usage Scenarios
Early Stage Fire: When a fire has just started and is within a controllable range, fire hose reels are ideal tools for rapid firefighting. Their design features make them more suitable for use in the early stages of a fire, rather than in the middle or later stages when the fire has spread.
Localized Fires: Fire hose reels have a water supply rate of 1.0 L/(s·m²), a supply time of 10 minutes, and a coverage area of approximately 20-30 m². They are suitable for small-scale localized fires, such as initial fires in offices, residences, or small commercial spaces.
Advantages of Use
Easy to Operate: Fire hose reels are typically equipped with simple on/off valves and lightweight spray guns, requiring no complicated operating procedures. Ordinary personnel can quickly use them after basic training.
Rapid Response: Utilizing an atmospheric pressure water supply design, water is available within 5-10 seconds of unfolding. Compared to systems that require connecting fire hoses and starting fire pumps (such as fire hydrants), the response speed is increased by approximately 80%, effectively meeting the "golden three minutes" requirement for extinguishing initial fires.
Lightweight and Flexible: Compared to traditional hoses, fire hose reels are much lighter and more portable. When extinguishing a fire, simply pull out the hose; minimal physical strength and technical skills are required, and a single person can operate it.
Usage Limitations
- Low Water Output:The water output of fire hose reels is far less than that of fire hoses, making them unsuitable for handling mid-stage fires that have spread. When the heat radiation intensity of the fire exceeds 10kW/m², the water output from the hose is insufficient to provide effective fire suppression, potentially leading to fire control failure.
- Limited Water Storage:A single hose reel typically holds no more than 200L of water. In the mid-stage of a fire, insufficient water supply may result in fire suppression failure.
- Applicable Fire Severity:Fire protection codes categorize fire hose reels with fire hydrant systems and automatic sprinkler systems. Fire hose reels handle Class 1A fires (equivalent to cardboard box fires), fire hydrant systems handle Class 2A-4A fires, and automatic sprinkler systems cover larger-scale fires.
Operating Instructions
- Open the water supply control valve: Ensure a smooth water supply.
- Roll the fire hose reel: Unwind the hose.
- Pull out the hose and run towards the fire source: Quickly reach the fire point.
- Open the nozzle valve: Prepare to spray.
- Aim at the base of the flames to extinguish the fire effectively.
Precautions
Regular Inspection: Ensure the fire hose reel is in good condition and perform regular maintenance.
Training and Use: Relevant personnel should receive basic training and be familiar with the operating procedures.
Timely Replacement: According to regulations, the service life of a fire hose reel is 5 years. It should be replaced promptly after this period.
