Fire extinguishers are some of the most significant tools in preventing small fires from becoming life-threatening emergencies. Simple to use, compact, and successful, they're a vital safety device for homes, workplaces, vehicles, and public spaces.
How Fire Extinguishers Work
A fire extinguisher is a pressurised container full of an agent meant to suppress flames. When activated, the agent is released under pressure to chill the burning material, smother flames, or disrupt the chemical reaction that sustains the fire. Different extinguishers use different agents—including water, foam, carbon dioxide (CO₂), dry powder, or wet chemicals—each suitable for particular fire types.
Classes of Fire and Matching Extinguishers
Fires are classified according to the fuel source:
Class A: Combustible solids like wood, paper, and textiles. Best tackled with water or foam extinguishers.
Class B: Flammable liquids including petrol, paint, or solvents. Foam, COâ‚‚, or dry powder is most effective.
Class C: Flammable gases like propane or butane. Dry powder extinguishers are recommended.
Class D: Combustible metals for example magnesium or sodium. Specialised powder agents are essential.
Class E (Electrical): Fires involving electrical equipment. COâ‚‚ or dry powder extinguishers are safest.
Class F: Cooking oils and fats. Wet chemical extinguishers are designed for these high-heat fires.
Using the wrong extinguisher type can be dangerous—for example, using water with an electrical or oil fire may spread flames or cause electrocution.
When and How to Use
Fire extinguishers are prepared for small, contained fires. If a hearth is spreading rapidly or room is filling with smoke, evacuate immediately and call emergency services.
When it’s safe to proceed, recall the PASS technique:
Pull the pin
Aim the nozzle on the base of the fireplace
Squeeze the handle
Sweep from side to side
Regular checks are essential—ensure extinguishers will be in date, undamaged, and correctly pressurised.
