This invention comprises a method of dispensing water-based decontaminants from a dispenser, comprising the steps of: (a) filling one or more tanks each with respective solutions of chemicals and water; (b) pumping the solutions from the tanks in respective hoses, each of the tanks being evacuated under the urging of a respective pump; (c) mixing the solutions at a static mixer after evacuation of the solutions from the tanks to form a mixture; (d) adding water to the mixture at the static mixer; and (e) dispensing the water-added mixture onto an incident site.

Method of, and apparatus for the dispensing of decontaminants and fire suppressant foam

Defoaming equipment, and more particularly, removing, defoaming, and storing large amounts of foam after a Blast Mitigation or Decontamination Foam has been used in either an open area or in an contained area is described. An apparatus is provided for defoaming, comprising: a vacuum system, including a vacuum head for drawing the foam through a suction hose terminating in a nozzle, that feeds the foam into a holding tank that initially stores a quantity of defoaming agent, and a pump drawing the defoaming agent from the holding tank to at least one injector that is fitted on the vacuum-side of the vacuum system, whereby the defoaming agent is actively mixed with the collected foam, reducing the collected foam. The reduced foam and defoaming agent are recirculated through the pump and the nozzle, the suction hose, the vacuum system, the injector and holding tank are of chemical-resistant construction.
