Decontamination Procedures for Personnel and Areas 1942 US Army

Decontamination is the removal and/or neutralization of hazardous levels of chemical and biological contamination from personnel, material, or the ground. Following the introduction of large-scale chemical warfare during World War I, the need to decontaminate after a chemical attack became a major concern of the Chemical Warfare Service, the forerunner of the Military Chemical Corps. Water was one of the earliest known decontaminants. Rain showers washed away ground pollutants while bathing eliminated bodily contamination. Waters capability to breakdown and decompose substances, called hydrolysis, was used to change toxic substances into useable products. Hydrated lime and bleaching powder is also used to neutralize the agent on the ground and on equipment. The success of this initial decontamination operation led to the birth of the modern concept of battlefield decontamination. Many of these procedures were adopted and modified for use in hazardous materials responses and cleanup in the 1970s and 1980s.
