What are the basic decontamination steps in a field exposure to chemical agents?

• A. Remove contaminated clothing, then wash exposed skin with clean water
• B. Wash exposed skin, then remove clothing
• C. Only wash hands
• D. Ignore decontamination

Answer: (A)

Decontamination in the field starts with removing the source of contamination and then cleaning the skin. The best sequence is to first take off any clothing that may be contaminated, because clothing can hold onto the chemical and spread it to skin or to others. Once the contaminated clothing is removed, wash the exposed skin with clean water to flush away any remaining agent. This order minimizes transfer and absorption and is the quickest, safest approach in a field setting. Washing the skin before removing clothing leaves contaminated fabric in contact with skin and can allow the agent to spread or remain on clothing, making decontamination less effective. Washing only the hands ignores exposed areas like arms or face, and ignoring decontamination altogether is dangerous and unacceptable.
