When is secondary decontamination performed?

• A. Immediately at the point of exposure
• B. Never
• C. Later, in controlled areas, for thorough removal before re-entry or custody
• D. Only after medical evaluation

Answer: (C)

Secondary decontamination is done after the initial exposure has been addressed, in a controlled area, to thoroughly remove any remaining contaminants before a person re-enters clean zones or is handed over for custody. The on-scene, immediate decontamination reduces exposure right away, but residues can still be carried on skin or clothing, so this later step ensures complete decontamination in a protected environment without risking spread during transport or transfer. It wouldn’t be done immediately at exposure, and it shouldn’t be postponed beyond the point of safe handling; it is specifically placed to occur in controlled areas for a thorough clean before re-entry or custody.
