Define "lockout/tagout" in the context of EM 385-1-1.

"Lockout/tagout" in the context of EM 385-1-1 refers to a procedure designed to ensure that machines are properly shut off and are unable to be started up again until maintenance work is completed. This safety protocol is critical for protecting workers from the unexpected energization or startup of machinery during maintenance or servicing activities.

The process involves using locks and tags to indicate that a machine should not be operated. The lockout component effectively prevents access to energy sources, while the tagout component serves as a warning that the machine is not to be operated until it is removed. This method is essential for maintaining a safe work environment, especially in industries where machinery can unexpectedly become dangerous if not properly secured. Implementing effective lockout/tagout procedures significantly reduces the risk of accidents and injuries in the workplace related to machinery operation.
