To maintain safety, personnel must not be under the influence of what types of substances?

Maintaining safety in various environments, especially in workplaces that require high levels of focus and physical ability, necessitates that personnel not be under the influence of both legal and illegal substances. This includes not just illegal drugs and alcohol, but also prescription medications that may impact cognitive or physical functioning. The rationale behind this requirement is to ensure that all personnel can perform their duties effectively and safely, minimizing the risk of accidents, injuries, or other safety breaches.

Legal substances such as alcohol and certain prescription medications can impair judgment, coordination, and reaction times, just as illegal drugs can. Therefore, reinforcing a policy that prohibits the influence of any substance—whether it is legal or illegal—is critical for maintaining a safe working environment. This comprehensive approach ensures that all factors that could compromise safety are addressed rather than focusing on specific categories, thus fostering an overall culture of safety and responsibility.
