After decontamination, personnel may be advised to do what before returning to service?

Changing clothes and taking a shower after decontamination is crucial for ensuring that personnel are fully cleaned of any contaminants or hazardous materials that may remain on their skin or clothing. This practice not only promotes personal hygiene but also reduces the risk of exposure to toxins that could potentially cause health issues. Showering helps to wash away any residues, while changing clothes prevents cross-contamination in the workplace or at home.

While group debriefs, additional training, and resting with hydration are all important components in the overall safety and well-being of personnel, they do not address the immediate need for personal cleanliness after a decontamination process. Prioritizing hygiene ensures that individuals can safely return to their duties without carrying over any harmful substances.
