  DECONTAMINATION
Decontamination is the reduction or removal of chemical agents.
Decontamination at the medical treatment facility prevents spread of the agent to areas of the body previously uncontaminated, contamination of personnel assisting the patient, and contamination of the medical facility.
Decontamination at the medical treatment facility is directed toward (1) eliminating any agent transferred to the patient during removal of protective clothing; (2) decontaminating or containing of contaminated clothing and personal equipment; and (3) maintaining an uncontaminated treatment facility.

 EPA: Federal Register: Pesticide Worker Protection Standard; Decontamination Requirements
With regard to the decontamination requirement, several commodity and other groups stated their belief that the duration of the 30-day requirement is unnecessary because decontamination supplies must be provided even when there is no apparent risk, in their estimation.
Retaining decontamination requirements for a period of 30 days after the expiration of an REI for pesticides other than the low toxicity pesticides lessens the chances that workers will be harmed by pesticide residues and decreases their chronic exposures to pesticides.
If decontamination supplies were the sole means of addressing drift, the Agency would have to require that supplies always be available, regardless of the length of the REI or the toxicity of the pesticide.

 ODP Fact Sheet - Mass Casualty Decontamination: Massachusetts' Rapid Response System
In the event of a chemical, biological, or radiological attack, a phased response system will be activated to provide for the decontamination of large numbers of people in a manner that maintains control of the incident, reduces harm to exposed persons, and prevents the spread of the agent by contaminated persons.
This Rapid Response System (RRS) relies on the immediate initiation of decontamination by local first responders, who are supported by a phased decontamination response that provides the local jurisdiction with the ability to access, decontaminate, and treat exposed persons, including those who cannot extricate themselves or be safely extricated.
These units also carry the mass casualty decontamination system, consisting of tents, decontamination pools, heaters, lights, water manifolds, hoses and wands, and a locally developed rail system that allows for the free movement of stretcher-borne casualties.
