Amerex 557 Sodium Chloride Chemical (Super D), 30 lb. Pail
Dry sodium chloride extinguishing agent designed for high-temperature combustible metal fire protection
The Amerex 557 Sodium Chloride Chemical (Super D) is a specialized Class D fire extinguishing agent formulated for controlling fires involving combustible metals such as magnesium, sodium, potassium, and aluminum alloys. Packaged in a 30 lb pail, this agent is intended for use with compatible Amerex Class D extinguishers including models B570 and 680.
When applied to a burning metal surface, the Super D sodium chloride formulation forms a heat-absorbing crust that helps isolate the fuel from oxygen and dissipate heat efficiently. This controlled smothering action assists in stabilizing hazardous metal fires commonly encountered in machining environments, foundries, laboratories, and specialized manufacturing operations.
