Decontamination foam

Decontamination foam (known commonly as Decon foam) is a spray-on cleaning solution that, due to its physical properties, has a longer residence time on contaminated surfaces than reular liquids and thus provides efficient decontamination of biological and chemical contaminants (e.g. chemical warfare agents, anthrax spores or other toxic industrial materials(TIM)).

It is designed for use in emergency situations involving areas containing large numbers of possibly contaminated people e.g. at conventions, airports, concerts etc.

Soap cannons and other foam delivery systems in practice
The LAX airport soap cannon can spray large quantities of decon foam on crowds of potentially exposed persons, e.g. to decon an entire planeload of people who might be victims of a nuclear, chemical, or biological agent release.

Mixing and using decon foam
Decon foam often comes in two bottles, that, when mixed, expand to produce many times their volume in foam.

Using decon foam for crowd control
Decon foam is also useful as an area denial weapons medium for crowd control, e.g. to make the ground slippery, as well as to reduce visibility (as a fog), such as with the CASCAD product.
