Intro to Millwright Practice Exam

What signifies that a lockout/tagout procedure was properly followed?

1. Machinery is running smoothly

2. Documentation is complete

3. Employees are trained

4. Keys are missing

The correct answer is: Documentation is complete

A complete and thorough documentation is vital in lockout/tagout procedures as it serves as a formal record indicating that the necessary safety steps have been taken to ensure that machinery is correctly shut down and unable to be restarted while maintenance or repair work is being performed. Proper documentation includes lists of the equipment affected, the steps taken to achieve lockout/tagout, the individuals involved in the process, and confirmation of the removal of locks or tags once the work is finished. Without proper documentation, it would be difficult to verify that all safety protocols were adhered to, which increases the risk of accidental machine startup and worker injury. In contrast, while smooth machine operation or employee training are important facets of workplace safety and effective operation, they alone do not confirm that the lockout/tagout procedure was executed correctly. Likewise, missing keys could indicate a lack of control and proper adherence to safety measures during the process. Therefore, completed documentation serves as the definitive proof that the lockout/tagout procedure was successfully followed.
