Foam-oxidizing decontaminants consisting of a binary mixture of surfactants and mild oxidizers intended to transform the chemical agents into nontoxic substances; they may also be effective in killing bacteria, spores, and viruses. Binary spray foam decontaminants are usually supplied as a twin liquid sprayer device. The simultaneous delivery of both sprays combine to form a foam that expands to many (e.g., 100) times its liquid volume; the foam collapses back as a nondangerous toxic liquid form in a few hours. They are intended for decontamination from nerve agents of the G series and VX, mustard (HD), and biological agents such as anthrax.
