crowd control, e.g. to make the ground slippery, as well as to reduce visibility (as a fog) 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 Decontamination of methamphetamine labs Mold remediation Disinfection of hospitals and schools Pesticide removal Military applications Preventative measure at presidential debates Benefits of decontamination foam over other decontaminants The two main benefits of decontamination foam over liquid decontaminants (chlorine, decontamination solutions, etc.) are its effectiveness on non horizontal surfaces and its high air to liquid ratio. Other decontaminants are difficult to apply to walls and ceilings due to poor adhesion, however decon foam is much better at adhering to surfaces, which increases the amount of time for the decontamination reaction to take place. Additionally, the high air to liquid ratio allows the foam to be used without over-applying the decontaminant. This high ratio also allows a small amount of liquid to cover a relatively large area in the event of a major contamination.
