A worker's behavior that leads to a significant safety risk will likely result in what type of testing?

The correct answer is based on the specific circumstances surrounding behavior that poses a notable safety risk in the workplace. Post-event testing occurs after an incident or noticeable behavioral issue has taken place, typically when there is evidence suggesting that an individual’s actions may have contributed to a safety violation or accident. This testing is conducted to evaluate the fit of the employee for their duties and to ensure the overall safety of the workplace.

In this scenario, post-event testing serves as a crucial tool for assessing whether impairment or other factors influenced the unsafe behavior, thereby providing both a corrective action for the individual and a preventive measure for future incidents. It can help identify whether substance use or other issues were at play, which is essential for maintaining safety standards.

Other types of testing, while they serve important functions, do not apply in this specific context. Random testing is planned without suspicion and not necessarily linked to specific incidents; follow-up testing often relates to monitoring an employee after they have undergone prior treatment or issues; and for-cause testing is based on specific evidence or behavior that suggests impairment, which may apply but doesn't typically occur in the aftermath of a recognized safety risk incident as explicitly as post-event testing does.
