Fire extinguishers are among the most significant tools in preventing small fires from becoming life-threatening emergencies. Simple to use, compact, and impressive, these are an important safety device for homes, workplaces, vehicles, and public spaces.
How Fire Extinguishers Work
A fire extinguisher is often a pressurised container filled with a representative made to suppress flames. When activated, the agent is released under time limits to cool the burning material, smother flames, or disrupt caffeine reaction that sustains the hearth. Different extinguishers use different agents—such as water, foam, fractional co2 (CO₂), dry powder, or wet chemicals—each worthy of particular fire types.
Classes of Fire and Matching Extinguishers
Fires are classified based on 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 check here 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 focus on these high-heat fires.
Using the wrong extinguisher type could be dangerous—as an example, using water by using 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 hearth is spreading rapidly or 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 at the base of the fire

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