A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist, but are less common.

Understanding Fire Classes:It’s essential to match the extinguisher to the potential fire hazard:

• Dry Powder (ABC) Extinguishers: The most versatile type, effective against Class A (wood, paper), B (flammable liquids), and C (electrical) fires.
• CO2 (Carbon Dioxide) Extinguishers: Ideal for electrical fires (Class C) and flammable liquids (Class B), as they leave no residue. Perfect for server rooms and kitchens.
• Foam Extinguishers: Effective on Class A and B fires.
• Water Extinguishers
