Who is responsible for lock out/tag out when two mechanical contractors are working on a common steam line?

In a scenario where two mechanical contractors are working on a common steam line, each person involved in the work holds responsibility for lockout/tagout (LOTO) procedures. This collective responsibility ensures that all workers are aware of the hazardous energy sources and are protected from accidental start-up or release of hazardous energy during maintenance and repair tasks.

The reason why each individual working on the steam line is accountable stems from the principle that LOTO is designed to protect the safety of all personnel engaged in the operation. By sharing the responsibility, it reinforces the importance of communication and coordination between the two contractors, which helps to avoid accidents and ensure everyone is properly safeguarded. Each worker must verify that their own lockout/tagout devices are effective and that they have communicated their presence and actions to others on the job site.

While options such as a lead contractor, site supervisor, or a single individual from either contractor may seem responsible for overseeing safety, they do not account for the decentralized nature of lockout/tagout procedures. A system where everyone is responsible helps create a safer work environment and fosters accountability among all individuals involved, aligning with OSHA regulations and best practices in safety management.
