Decontaminated personnel must undergo medical evaluation at what time?

• A. They must undergo medical evaluation after exiting the decon zone.
• B. They must undergo medical evaluation prior to rehab.
• C. They must undergo medical evaluation immediately upon exiting the decon zone.
• D. They must be quarantined until cleared for release.

Answer: (C)

Medical evaluation should happen immediately upon exiting the decontamination zone. This timing is essential because any residual contaminants on skin or garments may still pose a risk even after decon steps are completed. An immediate evaluation lets responders assess exposure status, check vital signs, identify any symptoms, and determine if further medical care or additional decontamination is needed, all before the person moves into rehab or other areas. Delaying evaluation or waiting until after rehab can allow contaminants to spread or symptoms to manifest, and quarantining until release isn’t necessary or practical. By evaluating right at the point of exit, the process confirms decontamination effectiveness and ensures timely medical care.
