What is the correct sequence to safely perform a Lockout/Tagout?

The correct sequence for performing a Lockout/Tagout (LOTO) procedure is significant for ensuring safety when servicing or maintaining machinery or equipment that could inadvertently start up. The first step involves notifying all affected employees about the maintenance work to ensure they are aware that operations will be temporarily halted. This is crucial for preventing any unintentional actions by those operating or near the machinery during the lockout process.

After notification, the next step is to shut down the equipment properly. This ensures that it is completely turned off before any further safety measures are applied. Following the shutdown, isolating the energy sources of the machinery is essential. This could include disconnecting power sources, shutting off gas valves, or locking out hydraulic systems.

Once the energy sources are effectively isolated, the next step is to apply appropriate Lockout/Tagout devices. These devices serve as a physical barrier to prevent the machinery from being energized accidentally while maintenance is ongoing and also serve as a clear indicator that the equipment should not be operated.

This correct sequence minimizes the risk of accidents and ensures that all necessary precautions are taken to safely work on the equipment. Each step builds upon the last, reinforcing the principle of safeguarding personnel during maintenance activities.
