What Each Different Type of Fire Extinguisher Is Used For

Water Fire Extinguishers

These fire extinguishers are best for use on fires involving ordinary materials like wood, paper and fabrics. They produce a steady jet of water that can be directed to the fire. These aren't suitable for using on flames on live electrical equipment or burning oil or fat.

Carbon Dioxide Fire Extinguishers

These fire extinguishers are thought for scenarios involving live electrical dangers or flammable liquids. Since they're just producing a gas they cause very little damage and so are good for use on printers, photocopiers faxes, etc.. Though they may be utilized perfectly on any electrical equipment, they can't be guaranteed to not cause any harm at all to delicate electronic devices and IT equipment.

Foam Fire Extinguishers

These fire extinguishers are safe on precisely the same sort of materials which you would use a water dispenser, and in addition may be used on flammable liquids such as gas, diesel, solvents and spirits. They create a foam that seals in vapours to avoid the fire re-igniting. These extinguishers aren't, however, appropriate to be used on deep fat fryers.

Dry Powder Fire Extinguishers

These are a flexible fire extinguisher, which may be used on fires with flammable gases like butane and propane. They are also safe on electrical fires, but are likely to cause more damage than the usual Carbon Dioxide extinguisher. Because of the character of this fine powder created, they are not recommended to be used in confined spaces or by people with breathing issues.

Types of Fire Extinguisher - How Many Should I Have?

For general work areas such as offices, shops and similar regions having no specific hazards, you ought to be supplying water fire extinguishers. Concerning the amount you want to provide, the official requirement is that you just need one for each 200 square yards of floor space, subject to a minimum of two fire extinguishers on each floor.

Where Should The Fire Extinguishers Be Located?

Unless an extinguisher has been supplied to deal with a particular risk, they should be located at key points on your emergency escape routes. Key locations are adjacent to fire exit doors, near the exit from a floor or space, etc..
If an extinguisher is intended to cover a specific risk, such as a hot fat fryer in a kitchen, then it obviously needs to be sited from the area near to the hazard it relates to.

The very best way of fixing is to attach your fire extinguishers into a wall by a special bracket. This places them at a good height for visibility and access as well as offering a level of protection from being knocked over or moved. Where this isn't feasible, you can acquire free standing units that the fire extinguisher sits in. This helps to provide them a more permanent position than when they were only by themselves and makes them less inclined to be transferred or damaged.

Maintenance And Testing of Fire Extinguishers

Part of this duty about the Responsible Person will be to properly maintain all of your fire fighting equipment, as it may as well not be there if it's not in working order. The very best method to ensure this is to prepare a maintenance contract with a specialist business to inspect your extinguishers at least a year. This will then give you documentary evidence that you have taken proper precautions, if anything go wrong in future.

In between reviews you should execute your own regular tests. These can just entail recording the fact that you have checked that each extinguisher is in its proper place and hasn't been discharged or damaged. You should maintain a record of this in a log book in case the Fire Authority wish to scrutinize it. Again the documentary proof of your reviews could be rather helpful.
