What four matters must the Mine Isolation, Lockout and Tagging System address?

The Mine Isolation, Lockout and Tagging System is a critical safety protocol in the mining industry, designed to prevent accidents associated with the unexpected release of energy from equipment during maintenance or other servicing activities. Option B addresses the essential elements of controlling the risk of unplanned energy release and ensures that testing for zero potential is carried out. This is paramount because it involves identifying and isolating energy sources before any work begins, significantly minimizing the potential for accidents or injuries.

By focusing on controlling risks associated with energy release, the system ensures that all personnel can confidently perform their duties without the threat of unexpected machinery movements or other hazardous energy discharges. This is vital in maintaining a safe working environment, as it directly correlates with the health and safety regulations outlined in industrial safety standards.

While other options, such as training, documentation, and emergency drills, are important aspects of a comprehensive safety plan, they do not capture the core objectives of the Mine Isolation, Lockout, and Tagging System, which is explicitly focused on the isolation and safe handling of equipment during maintenance to prevent any unplanned energy release.
