A "lockout/tagout" procedure is a crucial safety protocol used in various industries, particularly in electrical and mechanical maintenance and inspection. It is designed to ensure that equipment is properly shut off and not able to be started up again until maintenance work is completed. This procedure typically involves locking the power source to an equipment or machine and placing a tag on it to indicate that it should not be operated. This prevents accidental energization, which could lead to severe injuries or fatalities among workers during maintenance activities.

The significance of lockout/tagout procedures cannot be overstated, as they provide a systematic approach to managing hazardous energy releases—both electrical and mechanical—thereby safeguarding employees and maintaining a safe work environment. Properly implementing lockout/tagout procedures is a requirement under various safety regulations, including those from the Occupational Safety and Health Administration (OSHA).

While other options mention different practices related to electricity, none address the critical aspect of safety that lockout/tagout specifically targets, making it the clear and appropriate choice in this context.
