The process of rapidly reducing or removing contaminants from multiple persons, and potentially life-threatening situation, is known as __________ decontamination.

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

Answer: (A)

Mass decontamination is the rapid removal of contaminants from a large number of people in a life‑threatening situation. When many individuals are contaminated and time is critical, the priority is speed and high throughput—setting up a decon line, promptly removing clothing, and quickly washing to dramatically cut contaminant levels. This approach protects both victims and responders and gets people ready for immediate medical care.

Other forms of decon exist for different contexts: emergency decon aims to quickly decontaminate individuals who are in immediate danger or require rapid access to care but usually for smaller groups; technical decon is a thorough, longer process used for specialized contaminants or equipment; routine decon is the slower, standard decontamination used in non-emergency settings. In a scenario involving many people and an urgent risk, mass decon is the appropriate choice because it emphasizes speed and scale.
