Amerex 548 Copper Agent Class D Chemical, 50 lb. Pail
Copper-based Class D extinguishing agent engineered for lithium and combustible metal fire protection
The Amerex 548 Copper Agent Class D chemical is a specialized extinguishing agent designed for controlling fires involving lithium and other reactive combustible metals. Supplied in a 50 lb pail, this agent supports recharge and maintenance requirements for compatible Amerex Class D extinguishers including Navy 125S, B571, C571, and model 681.
When applied to burning lithium metal, the copper-based formulation forms a heat-conductive crust that helps absorb heat and isolate the fuel surface from oxygen. This controlled suppression approach helps reduce fire intensity while minimizing the risk of violent reaction commonly associated with water or standard extinguishing agents in lithium hazard environments.
