Which of the following is NOT a standard decontamination step?

• A. Remove contaminated clothing
• B. Brush off dry chemicals
• C. Flush skin with water
• D. Apply ointment to skin

Answer: (D)

The main idea is that decontamination should remove or dilute the contaminant as quickly as possible to minimize absorption and injury. Start by removing contaminated clothing to eliminate the source of exposure, then brush off any dry chemicals so particulates aren’t pushed into the skin or dissolved in moisture, and finally flush the skin with water to wash away residues. Applying ointment to the skin is not part of standard decontamination because ointments can trap residual chemical against the skin, slow or hinder washing, and may react with certain chemicals. After decontamination is complete, medical care can address any burns or irritation, including appropriate skin treatments, but not as a step in the decontamination process itself.
