A Guide to Class C Fires (Flammable Gases)

It’s a common misconception that the differences between fires are obsolete. In reality, it can be life saving to know the about classes of fire, ensuring you can be fully equipped for the type of fire you are most likely to experience at your particular workplace.

The methods of extinguishing different fires can vary greatly, and the following guide provides all you need to know about Class C (flammable gas) fires.

It is always best to call 999 if you’re in any doubt as to whether to tackle any fire. Class C fires in particular can involve highly explosive materials, so it’s better to be safe than sorry.

What is a Class C fire?

A Class C fire is the burning of flammable gases. These can include butane and propane, found in gas canisters used for camping stoves and gas barbecues. The natural gases used in stoves or heating systems are also flammable; these fires tend to occur when leaks are present, or flames have accidentally got too close to where gas is stored.

Preventing a Class C fire

To prevent Class C fires that burn flammable gas, ensure all the equipment in your commercial environment, and at home, is modern and up to date. Make sure you always enlist the help of a professional when carrying out any necessary work to minimise the risk of leaks.

Don’t store lots of gas in one place – only keep what you need. This eliminates the risk of a larger scale explosion. Also, never leave gas canisters close to heat sources, and always make sure that if you smell gas, switch off all appliances and contact a professional immediately.

Make sure all safety equipment is well maintained and test all fire alarms and extinguishers regularly, ensuring they are the best suited products for your particular environment.

Dry Powder Fire Extinguishers

Only dry powder fire extinguishers are safe to use on gas (Class C) fires. If you use any other type of extinguisher, it will at best be ineffective, but it is more than likely to be highly dangerous. It is particularly hazardous to use carbon dioxide or wet chemical extinguishers on flammable gas fires.
