Understanding fire classes helps buyers specify the right extinguisher and meet local regulations.

Class A — ordinary combustibles

Wood, paper, textiles and plastics. ABC powder smothers and interrupts the chain reaction.

Class B — flammable liquids

Petrol, diesel, solvents and oils. The powder blanket prevents re-ignition.

Class C — flammable gases

LPG, natural gas and similar. ABC powder is effective, though the gas source must still be isolated.

Electrical equipment

ABC dry powder is non-conductive and safe on live equipment up to the rated test voltage, making it ideal for offices, factories and vehicles.

Our ABC units are rated 13A–55A / 55B–233B / C depending on capacity. Sichuan Longshengan Fire Equipment Co., Ltd. supplies the full 1kg–50kg range with CE/EN3 where applicable.
