Here is a quick guide to help you choose the right fire extinguisher for the right part of your home. If you are in any doubt, we advise that you contact your local fire station for more help and information.
Co2
This type of extinguisher can be used on the widest range of fires within a home. It is ideal for use on textiles, wood, flammable liquids and electrical fires. It cannot be used on fires caused by cooking fats or oils. This is a good device for living areas and garages. The kitchen requires an alternative device such as a fire blanket.
Water
Water fire extinguishers are ideal for putting out fires on furniture and carpets but are dangerous when used on flammable liquids or cooking fats. Water fire extinguishers are best kept and used in bedrooms and living rooms.
Foam
Foam extinguishers are most effective on wood and flammable liquids, petrol, spirits but not for electrical fires. This type of extinguisher is best kept in the garage or shed, where these kinds of products can usually be found.
Fire Blanket
A fire blanket is ideally located on a wall in an easy-to-reach place in a kitchen. It can stop small pan-fires from spreading. They can also be used to smoulder flames, if someone has caught their clothes alight.
