Class C: Flammable gases like propane or butane. Dry powder extinguishers are recommended.
Class D: Combustible metals such as magnesium or sodium. Specialised powder agents are expected.
Class E (Electrical): Fires involving electrical equipment. COâ‚‚ or dry powder extinguishers are safest.
Class F: Cooking oils and fats. Wet chemical extinguishers are prepared for these high-heat fires.
Using the incorrect extinguisher type can click here be dangerous—for example, using water by using an electrical or oil fire may spread flames or cause electrocution.

When it’s safe to proceed, remember the PASS technique:
Pull the pin
Aim the nozzle on the base of the fire
Squeeze the handle
Sweep from side to side
Regular checks are essential—ensure extinguishers come in date, undamaged, and correctly pressurised.
