In a life-threatening exposure, what is the priority regarding decontamination timing?

• A. Delayed decontamination
• B. Immediate decontamination
• C. Drip decontamination
• D. Postponed decontamination

Answer: (B)

Immediate decontamination is the priority because removing the contaminant from the body as quickly as possible minimizes ongoing absorption and limits secondary exposure to others. In a life-threatening exposure, you should not delay essential life-saving care—decontamination should start right away if it can be done safely and without delaying critical interventions like airway, breathing, and circulation. Actions are rapid and focused: remove contaminated clothing, brush off dry residues if present, and rinse the skin with water as soon as possible, with decontamination performed in parallel with ongoing resuscitation or treatment whenever feasible. If life support must come first, provide it promptly and begin decontamination as soon as possible thereafter to reduce toxin absorption.
