Which is a correct sequence for decontaminating a contaminated skin surface?

• A. Remove contaminated clothing, wash skin with soap and running water, rinse, avoid abrasive scrubbing, dry and inspect; consult medical care if needed
• B. Rinse first, then wash with soap, remove contaminated clothing, dry and inspect; ignore medical care
• C. Wash with water only, no removal of clothing
• D. Scrub vigorously with soap and water then re-dress

Answer: (A)

Removing contaminated clothing first is essential because it stops ongoing exposure and reduces the amount of contaminant remaining on the skin. Once the source is removed, washing the skin with soap and running water helps lift and dissolve residues that may be on the surface, and rinsing afterward flushes these contaminants away. Abrasive scrubbing should be avoided because it can irritate or injure the skin and may increase absorption of certain chemicals or worsen tissue damage. After washing and rinsing, drying and a careful inspection help identify any remaining contamination or skin injuries that may require further care. If there’s a risk of chemical exposure, symptoms, or uncertain contamination, seeking medical care ensures appropriate treatment and monitoring.

The other approaches fall short because rinsing alone or washing without first removing clothing allows ongoing exposure to continue; skipping the clothing removal keeps contaminants in contact with skin longer; and scrubbing vigorously can damage the skin and worsen the situation.
