What does "tag out" mean in a safety procedure?

The term "tag out" in a safety procedure refers specifically to the placement of a tag on equipment to communicate that it should not be operated. This practice is part of the Lockout/Tagout (LOTO) safety standards, which are designed to prevent accidental machine start-up during maintenance or repair work. When a tag is attached, it serves as a visual warning to ensure that personnel are aware that the equipment is unsafe to use.

The intent behind this procedure is to protect employees from unintentional activation of machinery that could cause injury or harm, particularly when machinery is being serviced. By identifying equipment that is 'tagged out', workers know there is a specific reason for the equipment being out of service, reinforcing a culture of safety in the workplace.

While other options may involve aspects of safety and equipment management, they do not encapsulate the primary definition and intent of "tag out" as effectively as the placement of tags to prevent operation during hazardous situations.
