What is the responsibility of the second person during an equipment tag-out procedure?

The responsibility of the second person during an equipment tag-out procedure focuses on ensuring that all safety measures are implemented effectively. This role is critical in preventing accidental energization of equipment during maintenance, which could lead to severe injuries or even fatalities.

By ensuring proper tag attachment and positioning of the switch or valve, the second person plays an essential part in the tag-out procedure. Properly placed tags serve as a clear indication to all personnel that the equipment is not to be operated. The accuracy of this positioning directly affects the effectiveness of the tag-out, allowing everyone in the vicinity to be aware of the status of the equipment and ensuring that the maintenance team can work safely.

It's also worth noting that while other roles like safety observers or working to verify de-energization are important, those tasks do not encompass the full scope of ensuring that the equipment is safely tagged out as described in the correct choice. The focus of the tag-out procedure emphasizes the necessity of the second person's involvement in securing the environment for maintenance work.
