A carbon dioxide fire extinguisher works on a Class B fire by expelling CO2 to suffocate the fire removing the oxygen necessary to keep it burning. A Class C fire is a fire that involves electrical equipment electrical appliances or electrical wiring.

But this classification typically does not include fires involving cooking oils or grease. A Class B fire is anything started by a flammable liquid such as petrol or alcohol. They are caused by energized electrical elements such as damaged power cors or overloaded electrical outlets.

Examples of flammable liquids include petrol oil paraffin alcohol and certain paints. Solid materials tend to have organic materials and carbon that causes them to combust. To avoid a class A fire from happening try to keep all.

So a class B fire is very dangerous as it is the burning of flammable liquids. Flammable Liquids and Gases. This will spread the flames.

But it is always best to disconnect the power source prior to fighting the fire. Caused by electrical equipment such as TVs computers faulty wiring frayed cables broken electrical appliancestools short circuits overloading multi-adaptor plug sockets hairdryers extension leads etc. Once the electrical item is removed the fire changes class.

If an extinguisher has a Class C rating it means that the agent will not conduct electricity. Its important to note however that cooking fats and oils are not included in this class. The class A fire uses these materials as fuel and the fire will die out once all the solid fuel runs out.

Beyond knowing your fire hazard classification you also need to understand your area hazard classification. Fire damage in this class involves fires related to flammable liquids as well as solid materials that can liquify. That normally do not leave any embers or residues or very low amounts of residues.
