How frequently should safety drills be conducted?

Conducting safety drills at least once a year, or as dictated by specific workplace requirements, is essential for ensuring that all employees are familiar with emergency procedures and can respond quickly and effectively in the event of a crisis. Regular drills reinforce safety protocols, enhance readiness, and allow employees to practice their roles in a controlled environment, which can significantly reduce panic and confusion during actual emergencies.

Moreover, different workplaces might have unique hazards or regulations that could require more frequent drills, making it critical to adhere to those tailored requirements. This not only meets compliance standards but also fosters a culture of safety within the organization by keeping emergency procedures fresh in everyone's mind.

The other options suggest infrequent or irregular practices that can lead to a lack of preparedness among employees, which may endanger lives and violate safety standards set by regulatory bodies like OSHA.
