Class C - Gas Fire

What is a Type D fire?

A Class D fire is characterised by the presence of burning metals. Only certain metals are flammable and examples of combustible metals include sodium, potassium, uranium, lithium, plutonium and calcium, with the most common Class D fires involve magnesium and titanium.

What is example of a Class C fire?

A Class C fire is the burning of flammable gases, which can be very dangerous and highly explosive. These include gases such as butane and propane in gas canisters, which you'd expect to find in certain building trades. You will also find these with gas camping stoves and gas barbeques.

Which fire extinguisher is suitable for Class C fire?

How do you handle Class C fires?

The most important thing to remember is that a class C fire cannot be fought with water; you must use non-conductive substances. Carbon dioxide fire extinguishers, and those loaded with a dry chemical like PKP, are effective. Conductive substances such as water or foam can put the fire fighter at risk.
