Allcooper supply and install a variety of fire extinguisher types

Extinguishers are an essential protection measure should your business experience a fire. Each type of extinguisher contains a different substance such as water, powder or foam, and is available in 3, 6 and 9 litre sizes. Carrying out a full Fire Risk Assessment will allow us to help determine which types of extinguishers you need and how many.

The importance of using the right type of extinguisher

As fires can be caused by many different types of combustible fuel, some extinguishers are more suited to dealing with certain types of fire than others. Using the wrong fire extinguisher on the wrong fire could make a situation worse. It’s important to understand the types of fire that you could potentially experience, so you know which fire extinguisher types are best to use.

Important note: Halon Fire Extinguishers were banned in the UK in 2003. This was due to scientific findings linking Halon substances to damage of the Earth's ozone layer. it is now illegal to hold an extinguisher of this type on your premises without special permission. They can be easily identified as they were green in colour, rather than red. If you have an old Halon Fire Extinguisher, we can help advise on disposing of these safely.
