What condition must be met for a worker to undergo post-event chemical testing?

The condition that must be met for a worker to undergo post-event chemical testing involves an event that meets OSHA recordable criteria. This means that if an incident occurs that results in a work-related injury or illness that is significant enough to be recorded under OSHA's recordkeeping regulations, then post-event chemical testing is warranted.

The rationale behind this requirement is to ensure workplace safety and to evaluate whether substance use may have contributed to the event that led to the recordable injury or incident. This testing helps to identify any potential risks and promotes a safer work environment by addressing substance-related issues if they exist.

In contrast, while hospitalization, behavioral violations, and indications of substance abuse can be important considerations in assessing a worker's fitness for duty, they are not universally applicable triggers for post-event chemical testing across all situations in the context of workplace safety standards established by OSHA. Only events that meet the specific recordable criteria signal the necessity for systematic chemical testing following an incident.
