What is the main purpose of a lockout/tagout (LOTO) procedure?

The main purpose of a lockout/tagout (LOTO) procedure is to prevent the accidental startup of machinery during maintenance. This critical safety protocol is implemented to ensure that the equipment is properly shut down and cannot be started up again until maintenance or repair work has been completed. By utilizing locks and tags, authorized personnel can visibly mark equipment that is being worked on, which helps to communicate that the equipment is not to be operated. This significantly reduces the risk of injury or accidents caused by unintended machinery operation, which can have severe consequences for employees who are servicing the equipment. Therefore, the emphasis on preventing accidental startup during maintenance is foundational to occupational health and safety practices.
