Used in life-threatening situations, the goal is to remove contaminant as quickly as possible.

• A. Delayed decontamination
• B. No decontamination
• C. Immediate decontamination
• D. Radiation decontamination

Answer: (C)

Immediate decontamination is the fastest way to reduce harm when a person is contaminated in a life-threatening situation. The quicker the contaminant is removed, the less chemical can be absorbed through skin or inhaled into the body, lowering the risk of serious toxicity. In practice, this means rapidly removing contaminated clothing, flushing exposed skin and eyes with copious clean water, and moving the person to fresh air if inhalation is a concern, all while continuing life-saving care. Delaying decontamination allows more of the contaminant to enter the body and worsen outcomes, and not decontaminating at all is unsafe. Radiation decontamination is a specialized process for radiological exposure and isn’t the default approach in most immediate contaminant emergencies; the priority in urgent cases is to remove the contaminant immediately.
