What is the primary function of a lock-out/tag-out system?

The primary function of a lock-out/tag-out system is to prevent accidental machinery startups. This safety procedure is crucial in ensuring that machinery cannot be inadvertently activated while maintenance or repair work is being performed. The system involves physically locking and tagging energy sources, such as electrical, mechanical, hydraulic, or pneumatic sources, to ensure that these sources are not re-energized until the work is completed and all personnel have moved to a safe distance.

By using lock-out/tag-out, workers can focus on their tasks without the risk of an unintended start-up, which could lead to severe injuries or fatalities. The system emphasizes the importance of clear communication and the enforcement of safety standards in the workplace, ensuring that everyone understands that the equipment is not safe to operate until it has been properly checked and all safety protocols have been adhered to.
