What does a lockout/tagout procedure ensure?

A lockout/tagout procedure is essential for ensuring that electrical systems are properly shut off and cannot be inadvertently started during maintenance. This procedure involves isolating the energy sources of machinery or systems and securing them in a manner that prevents their re-energization while maintenance work is being performed.

When a lockout/tagout process is implemented, it typically involves placing a lock on the energy isolating devices and attaching a tag that indicates the maintenance work taking place. This not only protects the individual performing the maintenance but also communicates to other personnel that they should not attempt to operate the machinery or system until the lockout/tagout has been removed. This is crucial in preventing accidents or injuries that could occur if equipment were to unexpectedly start while someone is working on it.

While the other options focus on safety aspects or accountability related to tools and personnel, they do not specifically address the main purpose of lockout/tagout procedures, which is to ensure safety during maintenance by securing the energy sources of electrical systems.
