How are the energy sources isolated during a lockout/tagout procedure?

The correct approach to isolating energy sources during a lockout/tagout procedure involves using distinctly marked locks on energy isolation devices. This method serves several critical functions that enhance safety.

Firstly, using distinctly marked locks ensures that only authorized personnel can access the energy sources. Each lock is specific to an individual worker, making it clear who is responsible for the isolation and who can re-energize the equipment. This prevents unauthorized access and ensures that workers are protected against accidental energization of machinery during maintenance work.

Furthermore, the clarity and visibility provided by distinctly marked locks act as a visual warning to others that maintenance is taking place. This communication is essential in a work environment where multiple employees may be present, as it minimizes the risk of misunderstanding or mistakenly attempting to operate the equipment while it is being serviced.

In contrast, while temporarily disconnecting the equipment can be part of the procedure, it is not sufficient by itself to ensure safety and compliance with lockout/tagout regulations. The physical disconnection must be accompanied by proper locking and tagging to prevent re-energization.

Placing equipment in a designated area and removing tools from the vicinity are important practices but do not directly address the isolation of energy sources. These actions can contribute to safety but do not provide the
