________ occurs outside of the incident area when people come in contact with a contaminated person or object.

• A. Primary Contamination
• B. Secondary Contamination
• C. Tertiary Contamination
• D. Quaternary Contamination

Answer: (B)

Secondary contamination occurs outside of the incident area when people come in contact with a contaminated person or object. This happens when the contaminant is carried beyond the hot zone by a person or by contaminated clothing, equipment, or surfaces, spreading to areas or individuals who were not directly involved in the initial exposure. The key is that the contamination moves from the incident scene into clean areas, which is why strict decontamination and careful doffing of PPE are essential to prevent spreading the contaminant. For contrast, contamination that happens right at the source within the incident area is primary contamination, while other terms used in some contexts are less relevant here.
