Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

What is the correct procedure to follow during a lockout/tagout operation?

1. Apply a lock that every worker has a key for

2. Apply your own lock, tag, and test for power

3. Apply a tag, lock and call your supervisor

4. Leave the key in the lock in case someone needs to use the equipment

The correct answer is: Apply your own lock, tag, and test for power

During a lockout/tagout operation, the correct procedure involves applying your own lock and tag to ensure that the equipment cannot be operated while you are performing maintenance or servicing tasks. This process is essential for worker safety, as it guarantees that only authorized personnel can access the equipment. Applying a lock signifies that the machinery is under maintenance and cannot be used until the lock is removed by the person who applied it. Additionally, tagging helps to communicate to others that the equipment is unsafe to operate and that maintenance is being performed. Testing for power after applying your own lock and tag further ensures that the machinery is in a zero-energy state and poses no risk of accidental startup. Following this protocol not only adheres to safety standards but also enhances accountability, as each worker is responsible for their own lock and tag. This minimizes the risk of equipment being accidentally operated, thus protecting both the individual performing the work and the surrounding personnel.
