Fires occur when there is a chemical reaction between heat, oxygen/air and fuel. All three elements must be present for a fire to start. If any one of the elements is removed, the fire will be extinguished. Fire extinguishers operate in a variety of ways. All fire extinguishers remove one or more of the elements, then the fire is extinguished. So Fire fighting equipment is very important in our daily life.
There are different types of fire extinguishers that are available to purchase, including water, dry powder, foam, wet chemical and carbon dioxide. Each type of extinguisher is classified and identified according to the type of fire that it will be put out. It is essential that the correct type of fire extinguisher is selected for the type of fire. Always remember that staff should be trained in the safe use of fire extinguishers. Fire extinguishers are pressurised containers and should always be handled with caution.
There are two main types of fire extinguishers: Stored Pressure and Cartridge Operated. Stored Pressure fire extinguishers are fully pressurised cylinders that contain a fire fighting agent and propellant. Cartridge operated fire extinguishers are not pressurised but contain a small gas cartridge that discharges into the unit when it is activated. Most extinguishers are made from steel or aluminium.
The number of fire extinguishers required depends up on the size of the premises and the risks involved. As a general guide, no person should ever be more than 30 metres away from a fire extinguisher. Fire extinguishers should always be placed where they are easily accessible. The type of building and the use will mean that different numbers and types of extinguishers will be required. Further information is available from a Fire Protection Engineer or your local Fire Service.
Fire extinguishers should be located where they can easily be viewed and they are quickly and easily accessible in case of an emergency. Fire extinguishers should be located on wall brackets or fire extinguisher stands and located on emergency escape routes. Fire extinguishers should be securely hung on wall brackets and attached to walls. It is also permissible to locate fire extinguishers on fire extinguisher floor stands or fire extinguisher boxes that can also be attached to walls. Fire extinguishers should not be placed directly on the floor.
The manufacturers instructions will tell you what you need to do to keep your extinguisher in good working order. After an extinguisher has been used, even if only partially, it must be recharged according to the manufacturers instructions.
The extinguisher should be serviced annually.
