Dry powder is a multi-purpose fire extinguishing medium with excellent knock-down properties. A dry powder fire extinguisher is often called an ABC unit because it can tackle Class A, B and C fires. The low minimum operating temperature of a powder fire extinguisher makes it suitable for all-year-round external situations. A powder fire extinguisher shouldn’t be used in confined spaces because the powder can be easily inhaled. Boasting PFAS free contents, consider this extinguisher for premises including garage forecourts, commercial boiler rooms and workspaces that feature welding.
