What is the first step of the lockout/tagout procedure?

  1. Remove the equipment from service

  2. Identify energy sources

  3. Notify all affected employees that a lockout/tagout system is going to be used and the reason why

  4. Apply the lockout/tagout devices

The correct answer is: Notify all affected employees that a lockout/tagout system is going to be used and the reason why

The first step of the lockout/tagout procedure is to notify all affected employees that a lockout/tagout system is going to be used and the reason why. This is essential to ensure that everyone in the area is aware of the ongoing procedure and the reason behind implementing it. It helps in preventing any accidental use of the equipment that is being locked out or tagged out, reducing the risks of accidents or injuries. Options A, B, and D are not the first step in the lockout/tagout procedure. Removing the equipment from service, identifying energy sources, and applying the lockout/tagout devices are important steps in the procedure, but they come after notifying all affected employees.
