Requirements for a Fire Hose Reel System
A fire hose reel system in Malaysia is an equipment mounted close to a fire service to provide uninterrupted water supply in the event of a fire outbreak.
The presence and ease of accessibility to fire hose reels helps people minimize damage caused by accidental fires and explosions in premises.
Firefighters and volunteers can efficiently initiate a quick response to a fire outbreak if a fire hose fitted in a building is full of pressurized water or a suitable fire-extinguishing agent.
Since fire hose reels are more effective than fire extinguishers and fire blankets, they are conveniently installed in premises with heavy traffic for quick access.
A fire hose reel system should be readily accessible to people occupying a building. Other than knowing the location of fire hoses in a building such as cabinets, it is also important to know how to use the hose reel in case of a fire.
Length and Diameter
The length of fire hoses often varies, but standard hose reels have a maximum extension length of 118 feet (36 meters). A hose reel with a diameter of between 0.5 inches (13mm) to 0.75 inches (19mm) should accommodate 11 ounces (0.33 liters) of water in a fire fighting situation.
Generally, a fire hose reel system is made up of a unique ball valve shut-off device, mounting bracket and a hose reel nozzle. The direction and flow of water from a hose reel is controlled by a nozzle located at the end of the fire hose.
Reliability and Storage
Other than plastic and stainless steel, hose reel nozzles are made of solid brass to improve durability and resistance to corrosion. However, stainless steel nozzles perform well in severe fire fighting conditions while the plastic nozzles have a longer shelf-life and are equally effective. Storage for hose reels should be either a wall-mounting casing or freestanding equipment that allows for mobility.
Sizing a Fire Hose
Hose reels are designed to take up little space by collapsing into a flat profile for storage purposes or for fire response situations, without compromising the inner layers of rubber and abrasion-resistant woven fabric.
Threaded metal connections on each end of a fire hose join other segments and/or fit into water nozzles at fire fighting points. Sizing is based on the size of the bowl, hose diameter, and the water or service pressure available at a site.
There are different types of fire hoses; therefore, it is important to determine the one to use in each unique circumstance. Examples of discharge hoses include attack, relay, supply, and booster hoses designed to handle for positive pressure. Suction hoses are recommended for negative pressure conditions like in severe weather where resistance to abrasion and wear is necessary.
Although fire hoses are flexible enough to meet or exceed water pressure requirements, you should be able to determine the service pressure in a particular location before you can use a fire hose. Be sure to refer to sticker instructions on the hose for details of the hose size, design, and method of use. Hose reels are a standard safety feature in many Malaysian office and residential buildings.
