Which statement about secondary contamination is true?

• A. Responders in the hot zone may contaminate others if they carry contamination outside the hot zone
• B. Secondary contamination is impossible with PPE
• C. Contamination is automatically removed when exiting the hot zone
• D. Decontamination is unnecessary if exposure was short

Answer: (A)

Secondary contamination happens when contaminants are carried out of the hot zone on clothing, PPE, or skin and then transfer to people or surfaces outside the controlled area. The statement that responders in the hot zone may contaminate others if they carry contamination outside the hot zone is true because contaminants can cling to gear or be left on skin, and without proper doffing and decontamination, those residues can be spread by touch or contact with surfaces and other people. This emphasizes why rigorous decontamination procedures and proper PPE removal are essential to prevent spreading contamination beyond the hot zone. The other options imply that PPE always prevents contamination, that leaving the hot zone cleans you automatically, or that decontamination isn’t needed if exposure is brief, none of which are accurate.
