If a contaminated person exits the hot zone without decontamination, the most likely result is:

• A. Contaminants would be transferred to other personnel or equipment.
• B. The contaminant would quickly dissipate and cause no further risk.
• C. There would be direct contamination of the warm zone.
• D. The individual would be permanently isolated from others.

Answer: (A)

Secondary contamination occurs when a contaminated person leaves the hot zone without decontamination, letting contaminants cling to skin, clothing, and gear and be carried into safer areas. The most likely result is that those contaminants get transferred to other personnel or to equipment they touch, or to surfaces and PPE in the warmer zones. Decontamination is critical to remove these residues and prevent spreading the contamination. Contaminants don’t simply disappear or dissipate on their own, so assuming no further risk after exiting the hot zone isn’t accurate. While the warm zone could become contaminated if the person and their gear move into it, the primary concern is the spread to people and equipment through contact or contact with contaminated surfaces. The idea of permanent isolation isn’t relevant to the immediate hazard in this context.
