Class C: Flammable gases like propane or butane. Dry powder extinguishers are recommended.

Class E (Electrical): Fires involving electrical equipment. COâ‚‚ or dry powder extinguishers are safest.
Class F: Cooking oils and fats. Wet chemical extinguishers focus on these high-heat fires.
Using the wrong extinguisher type can be dangerous—for instance, using water by using an electrical or oil fire may spread flames or cause electrocution.
