LW series dual-agent chambers combine both foam and dry-chemical applications to the internal fire. First a foam application will extinguish and secure the surface fire, then a secondary dry-chemical discharge dispels any residual flammable vapor above the foam blanket rendering the internal space inert thus allowing safe follow-up risk mitigation and recovery operations. These dual agent chambers are modified Williams LW series foam chambers, each fitted with additional piping and discharge tips for dry chemical. Used around the perimeter of a storage tank at a spacing of 80 feet (24.4 m), the dual agent chamber works in tandem with this network of adjacent foam chambers to apply a powerful dry-chemical attack that eliminates residual flammable vapors in the space above the foam blanket. LW series dual-agent foam chambers are a simple retrofit. It is compatible with the mounting dimensions and hardware for Williams LW series foam chambers.
