What is a Class B Fire Extinguisher Used for?

Class B fires involve flammable liquids such as petrol, alcohol, and paints, which are commonly found in petrol stations, factories, and food preparation facilities. A single spark can ignite these liquids, rapidly increasing temperatures to dangerous levels. If you store flammable liquids, it is crucial to be well-prepared.

Class B Fire Extinguishers

CO₂ Fire Extinguishers: Carbon dioxide (CO₂) extinguishers are highly effective for Class B fires, as they displace oxygen and suffocate the flames without leaving any residue. They are commonly used in areas with flammable liquids and electrical equipment. CO₂ extinguishers can be identified by their black label.

Dry Powder Extinguishers (ABC Powder): These versatile extinguishers are effective against Class A, B, and C fires, making them ideal for open areas where flammable liquids are present, such as petrol stations, garage forecourts, and workshops.

AFFF Foam Extinguishers: Designed for tackling flammable liquid fires, these extinguishers discharge a cooling foam that smothers the fire and prevents reignition. They can be identified by their cream-coloured label.
