In industrial settings, lockout/tagout procedures are crucial for preventing accidents related to hazardous energy sources. Authorized employees must evaluate, identify, and control energy sources to avoid unexpected startups or energy releases. These procedures cover servicing, maintenance, and normal operations, with a focus on safety measures to protect employees. An energy control program, preparation for shutdown, and specific shutdown procedures are essential elements of effective lockout/tagout practices.
