Terrorist organizations throughout the world have used a variety of chemical, biological, and radiological weapons (collectively known as HAZMAT/weapons of mass destruction [WMD]) to further their agendas. The possibility of such incidents requires first responders to prepare for such incidents, which can affect individuals or inflict mass casualties.
Incidents involving HAZMAT/WMD are complicated because victims may become contaminated with the hazardous material. The purpose of decontamination is to make an individual and/or their equipment safe by physically removing toxic substances quickly and easily.
