Mass Decon is defined as which process?

• A. Recovery Decon
• B. Mass Decon
• C. Technical Decon
• D. Emergency Decon

Answer: (B)

Mass decontamination is the rapid decontamination of a large number of people or equipment to quickly reduce surface contamination so they can be moved to safety. It uses high-throughput, field-ready methods—fast washdowns with water and basic rinsing techniques—prioritizing speed and volume over complete contaminant removal. This typically happens at the edge of the hot zone to process many victims or responders fast, enabling medical care and safe movement. It’s different from technical decon, which is thorough and equipment-intensive, and from recovery decon, which is the later, full-site cleanup. It also isn’t the immediate life-safety actions of emergency decon. So the defined process for rapid, large-scale decontamination is mass decon.
