Buckeye 5 lb Purple K BC Fire Extinguisher, Wall Mount or Vehicle Bracket

Purple K (potassium bicarbonate) is the dry chemical Buckeye describes as most effective on flammable liquid fires. It is rated for Class B and C fires, not Class A. This 5 lb unit comes with a discharge hose, rated 20-B:C, or a fixed nozzle, rated 10-B:C, and with a wall mount or a vehicle bracket. Both reach 12–18 ft (3.7–5.5 m); the hose unit discharges in 9 seconds and the fixed nozzle in 12. Buckeye does not recommend Purple K for sensitive electronic equipment.

Either discharge meets the 5-B:C minimum that 49 CFR 393.95 sets for commercial motor vehicle power units, and the 10-B:C required when transporting placarded hazardous materials. Buckeye builds it to ANSI/UL 299 and ANSI/UL 711 (UL and ULC listed), DOT and Transport Canada compliant, with a powder-coated steel cylinder and trilingual English, Spanish and French labels.
