Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

Under which condition is it acceptable to remove another employee's lockout lock?

1. When the employee who applied the lock left without removing it

2. After attempting to contact the employee

3. Only with permission from the employee who applied the lock

4. Only after all of the above have been done

The correct answer is: Only after all of the above have been done

The scenario described involves lockout/tagout procedures, which are critical for ensuring safety during maintenance work on machinery or equipment. The correct answer emphasizes a thorough and respectful approach to safety protocols. The process of removing someone else's lockout lock is serious because it can expose employees to hazardous energies. Therefore, it is essential to adhere to a strict protocol to ensure that everyone is safe and aware of the situation. Removing another employee's lock should only occur after attempting to contact that employee, as their presence and awareness are vital to ensuring safety. Getting permission from the employee who applied the lock not only honors their rights but confirms that they are indeed unavailable and that it is safe to proceed. Only after these steps have been completed should a lock be removed, which ensures that all necessary precautions have been taken to protect workers. This approach aligns with best practices in workplace safety, highlighting the importance of communication, respect for personal safety measures, and the collective responsibility for maintaining a safe working environment.
