What is the initial decontamination step for a person with suspected biological contamination?

• A. Rinse with alcohol wipe
• B. Remove clothing and jewelry, then rinse skin with water; wash with soap and water; avoid scrubbing.
• C. Remove clothing only, no rinse
• D. Immediate shower without removing clothing

Answer: (B)

Initial decontamination aims to quickly reduce exposure by removing contaminated sources and washing contaminants off the skin. Removing clothing and jewelry first takes away the bulk of the contaminant that is on fabrics and accessories, preventing transfer to skin and further spread. Then rinse the skin with water to physically wash away surface contamination, followed by washing with soap and water to help dissolve and remove residues that water alone may not eliminate. Scrubbing is avoided because it can irritate or injure the skin and may push contaminants deeper or spread them. This sequence minimizes contact and prepares the person for further medical care.
