UMD: Substances (i.e., decontamination agents) intended to destroy, physically remove, or reduce to acceptable levels contaminants such as chemical agents, radioactive materials, and toxic industrial material. Some decontaminants are also effective against biological agents (i.e., agents with germicidal capabilities). Decontaminants typically work by either removing (i.e., physical decontaminants) or neutralizing (i.e., chemical decontaminants) the contamination agent. These products can be used to decontaminate individuals (especially the skin), equipment, and/or installations (i.e., infrastructure).
