ABC powder extinguisher is the most versatile fire protection device. It is effective against :
Class A: dry or smouldering fires involving solid materials (wood, fabric, paper, cardboard, etc.).
- Class B: grease, liquid or liquefiable solid fires (hydrocarbons, alcohol, solvents, greases, oils, paints, etc.).
- class C: gas fires (propane, butane, methane, etc.). These powder extinguishers can also be used to extinguish electrical fires (electrical installations with a voltage of less than 1000V), as the powder is non-conductive. ABC powder extinguishers work by smothering the flames and isolating the fuel.
