Which scenario requires emergency decontamination?

Emergency decontamination is specifically required when there is an immediate health threat to victims who have been exposed to hazardous materials. In the context of the scenario, victim removal or recovery is a critical situation where individuals may have been contaminated. If these victims are brought out from the contaminated area, it is essential to conduct emergency decontamination procedures to prevent the spread of hazardous substances, protect emergency responders, and provide appropriate medical treatment.

During this scenario, effective decontamination can also reduce the potential for secondary contamination and mitigate further exposure to harmful substances. Unlike regular equipment monitoring, routine safety checks, or training exercises, which may involve planned procedures and timelines without immediate health threats, victim removal/recovery is an urgent matter requiring prompt action to safeguard health and prevent additional harm.
