Fire extinguishers are among the most crucial tools in preventing small fires from becoming life-threatening emergencies. Simple to use, compact, and noteworthy, these are a vital safety device for homes, workplaces, vehicles, and public spaces.
How Fire Extinguishers Work
A fire extinguisher is really a pressurised container full of an agent designed to suppress flames. When activated, the agent is released pressurized to cool the burning material, smother flames, or disrupt the chemical reaction that sustains the fire. Different extinguishers use different agents—for example water, foam, skin tightening and (CO₂), dry powder, or wet chemicals—each fitted to 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 like petrol, paint, or solvents. Foam, COâ‚‚, or dry powder is ideal.
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 required.
Class E (Electrical): Fires involving electrical equipment. COâ‚‚ or dry powder extinguishers are safest.
Class F: Cooking oils and fats. Wet chemical extinguishers are equipped for these high-heat fires.
Using the wrong extinguisher type can be dangerous—for example, using water on an electrical or oil fire may spread flames or cause electrocution.
When and How to Use
Fire extinguishers focus on small, contained fires. If a fire is spreading rapidly or room is filling with smoke, evacuate immediately and call emergency services.
When it’s safe to proceed, remember fondly the PASS technique:

Sweep from side to side
Regular checks are essential—ensure extinguishers have been in date, undamaged, and correctly pressurised.
