Fire extinguishers are one of the most crucial tools in preventing small fires from becoming life-threatening emergencies. Simple to use, compact, and highly effective, they are a crucial safety device for homes, workplaces, vehicles, and public spaces.
How Fire Extinguishers Work
A fire extinguisher is often a pressurised container filled with an agent designed to suppress flames. When activated, the agent is released under time limits to chill the burning material, smother flames, or disrupt caffeine reaction that sustains the hearth. Different extinguishers use different agents—including water, foam, fractional co2 (CO₂), dry powder, or wet chemicals—each suited 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 including 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 like magnesium or sodium. Specialised powder agents are needed.
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 a bad extinguisher type can be dangerous—for example, using water by using an electrical or oil fire may spread flames or cause electrocution.
When and How to Use
Fire extinguishers are designed for small, contained fires. If a fireplace is spreading rapidly or perhaps the room is filling with smoke, evacuate immediately and call emergency services.
When it’s safe to proceed, remember the PASS technique:
Pull the pin
Aim the nozzle in the base of the hearth
Squeeze the handle
Sweep from side to side
Regular checks are essential—ensure extinguishers come in date, undamaged, and correctly pressurised.
