Patent

CA 2300698

A decontamination formulation is provided which is effective against a broad spectrum of chemical and biological warfare agents and radioactive dusts, comprising an active decontamination agent, a co-solvent, a buffer system to optimize the initial reaction pH above 8.5 and more preferably in the range of to 11 for favoring oxidation of VX and HD and hydrolysis of G agents, and a surfactant similar to fire-fighting foaming agent. Formulations comprise, in water by weight, 1 % to 15% of a hydrated chloroisocyanuric acid salt, 1% to 10% of a polypropylene glycol co-solvent, 1 % to 15% surfactant and a buffer system to initially maintain said formulation at a pH from about 11 to about 8.5 for sufficient duration to effect decontamination. The formulation can be provided in kit form or concentrate form, be prepared, in part, in advance or on site, and be dispensed in foam form which aids in coating and adhering of the decontamination formulation to contaminated surfaces. All ingredients can be pumped through a foam nozzle or water, co-solvent and surfactant can be pumped to the nozzle with solutions of buffer and of active ingredient being introduced at the nozzle for minimizing pump exposure.
