After decontamination, what is required for highly exposed personnel prior to returning to duty?

Verification of full decontamination is essential for highly exposed personnel before returning to duty because it ensures that all harmful substances have been properly removed, minimizing the risk of health issues for both the individual and their colleagues. This step is crucial in maintaining safety standards and preventing further exposure, which could lead to contamination of equipment, vehicles, or the work environment.

While other choices might seem relevant, they do not specifically address the immediate concern of ensuring that personnel are free from contaminants. For instance, while a physical examination may be necessary in some cases, it comes after the confirmation of full decontamination. An immediate return to service without verification could put the individual and the team at risk, and creating a detailed report of the incident is important for documentation and analysis but does not directly relate to the safety of the returning personnel. Therefore, confirming that full decontamination has occurred is the most critical step before allowing anyone who was highly exposed to resume their duties.
