Fire extinguishers are some of the most important tools in preventing small fires from becoming life-threatening emergencies. Simple to use, compact, and highly effective, these are an essential safety device for homes, workplaces, vehicles, and public spaces.
How Fire Extinguishers Work
A fire extinguisher is often a pressurised container full of a real estate agent designed to suppress flames. When activated, the agent is released pressurized to cool down the the burning material, smother flames, or disrupt caffeine reaction that sustains the fireplace. Different extinguishers use different agents—for example water, foam, skin tightening and (CO₂), dry powder, or wet chemicals—each suited to particular fire types.
Classes of Fire and Matching Extinguishers
Fires are classified in accordance with the fuel source:
Class A: Combustible solids like wood, paper, and textiles. Best tackled with water or foam extinguishers.
Class B: Flammable liquids such as petrol, paint, or solvents. Foam, COâ‚‚, or dry powder website is best suited.
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 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 prepared for these high-heat fires.
Using an unacceptable extinguisher type can be dangerous—for instance, 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, remember fondly the PASS technique:
Pull the pin
Aim the nozzle at the base of the fire
Squeeze the handle
Sweep from side to side
Regular checks are essential—ensure extinguishers have been in date, undamaged, and correctly pressurised.
