Hose reels

Manually operated for general proteetion, e.g. hose reels, hydrants and foam installations, or Automatieally operated for general proteetion, e.g. sprinklers, or for speeial-risk proteetion, e.g. earbon dioxide installations.

Hose reels connected to the public water supply have the advantage that their supply of water is unlimited, although the pressure may be less than that generated in a portable extinguisher. Very large hoses are difficult to handle and lengths should not normally exceed 14 meters. Water should be immediately available when the control valve is opened.

When water is combined with other additives, it can control and extinguish most petroleum fires. A water suppression system consists of a supply source, distribution system, and the end using equipment such as fixed spray systems, monitors, hose reels and hydrants. The objective of water suppression systems is to provide exposure cooling, fire control, suppression of fire incidents and may assist in the dispersion of flammable or toxic vapors. 

A hydraulically designed system is preferred over standardized approach for optimization of the firewater flows, water storage requirements and piping materials. In any case, the main header should not be less than 203 mm (8 in.) in diameter. Piping routed to hydrants, monitors, hose reels and other protective systems should be at least 152 mm (6 in.) in diameter. 

Monitors are considered the primary manual water delivery device for hydrocarbon facilities, while hydrants and hose reels are considered secondary. Monitors are an initial manual fire suppression device that can be activated by operators with limited fire fighting training or experience. Use of hydrants and hoses usually require additional manpower and previous training. The use of a fire hose however, provides for more flexibility in the application of water sprays and where it may be needed when it is impractical to install a monitor. Monitors are usually placed at the process areas, while hydrants are placed at the perimeter roads, accessible to mobile apparatus. Most monitor pipe connections may also be fitted with fire hose connections. 

Hydrants should be considered as a backup water supply source to monitors and fixed fire suppression systems. Hydrants should be located on the ring main at intervals to suitably direct water on the fire hazard with a fire hose. Hydrants monitors and hose reels should be placed a minimum of 15 meters (50 ft.) from the hazard they protect for onshore facilities. Hydrants in process areas should be located so that any portion of a process unit can be reached from at least two opposite directions with the use of 76 meters (250 ft), hose lines if the approach is made from the upwind side of the fire. Offshore hydrants are located at the main accessways at the edge of the platform for each module. Normal access into a location should not be impeded by the placement of monitors or hydrants. This is especially important for heavy crane access during maintenance and turnaround activities. 

Hard rubber hose is preferred over collapsible fabric hose for process area hose reels and for preference of immediate availability. The rubber hose should not be allowed to be stored or exposed to direct sunlight for any considerable time period. 

The surface slope at the placement of all hydrants, monitors and hose reels should be slightly away from the device itself so water will drain away and prevent corrosion effects. Where automobile traffic may be prevalent, protective post or railing should be provided to prevent impacts to the devices. The protective barriers should not affect the hose connection, use of hoses or obscure the spray from monitors. The posts should be provided with highly visible markings or reflective paint.

Hose Reels and Hydrant Hoses Can be used to provide coverage to several hazards and then directed to specific incident occurring. Requires operator attendance for manual startup. 

Hard rubber fire hoses are usually provided throughout the process area of a hydrocarbon facility. The coil of a hose on a hose reel presents a considerable friction loss factor to the flow of water through it. In some instances a fire water hose reel may not be completely unrolled from a reel before its use. Therefore it is prudent to conduct a hose reel flow test with a partial removal of the hose and full unreeling from it. The spray reaches of each scenario can then be fully evaluated and observed. 

The ease of unrolling a hose reel to the protected hazard should be tested.

Fire water lines within process unit areas feeding more than two monitors, hose reels, or hydrants, should be connected to two separate sections of the fire main and separated by a valve in the main. Piping to hose reels and monitors should contain an isolation valve. 

Since control rooms are normally constantly manned, it is considered unlikely that a fire could progress undetected to a hazardous size. Fixed fire protection systems, whether manually or automatically activated, are seldom installed in control rooms of processing facilities, mainly due to the fact that they are normally constantly manned. As such, it is considered unlikely that any fire that does occur would progress undetected to a size that cannot be extinguished by manual intervention (fire extinguishers, hose reel, etc.). 

Hose Reel Cylinders around which fire hose may be manually or mechanically rolled to keep it neat and orderly. 

The Emergency Plan must identily aU the equipments that the emergency responders have and the equipments that they need to do their work properly. A map showing the location of fire hydrants, hose reels, safety showers, and other emergency equipment is needed. 

A Are hose reel for washing away spillages and dealing with smouldering sources of reignition— e.g. wood, paper—is generally useful but should be Atted with a variable jet/spray nozzle and needs to be protected Aom freezing. 

For these reasons the use of a water hose reel in factories is common and is suitable for most fires except those involving flammable liquids or live electrical equipment. 

Comply with requirements of insurance companies regarding fire fighting facilities to be provided on the premises, e.g. cast iron pipelines, dedicated water pumps of special design for fire fighting, separate power supply feeders/DG set, CO2 cylinders, sand buckets, dry chemical powder-type fire extinguishers, long hose reels smoke detectors, and sprinklers must be installed and maintained.

A device for compactly storing a hard rubber fire hose. It also allows the firewater nozzle to be readily used as the hose is being unwound from the reel. The hose is permanently connected to a water supply source at one end, and a nozzle is provided at the free end. A shutoff valve is provided on the pipe supplying water to the hose reel. Primarily installed on mobile fire apparatus vehicles and at industrial facilities. They generally are provided with 1.9-, 2.54-, or 3.8-centimeter (0.75-, 1.0-, or 1.5-inch) hoses that can be up to 60 meters (200 feet) in length and can be adapted for the application of foam water.
