What is the first step in an electrical lockout/tagout procedure?

The first step in an electrical lockout/tagout procedure is to shut down all energy sources. This step is crucial because it ensures that all forms of hazardous energy that could potentially injure workers are controlled before any maintenance or servicing work begins. By completely shutting down the machinery and disconnecting it from its power source, you significantly reduce the risk of accidental startup or energy release, which could cause severe injuries.

The subsequent steps, including locking and tagging the machinery as well as notifying coworkers, hinge upon the successful and complete shutdown of energy sources. Without this initial step, the effectiveness of the lockout/tagout process would be compromised, making it unsafe for personnel to proceed with their tasks. Emphasizing the importance of this first step helps reinforce the principles of worker safety and the need for thorough procedures in environments where hazardous energy is present.
