How to improve quality and efficiency with multiple energy lock-in points?

The open inspection and maintenance environment forms multiple energy lock-in points, which poses significant challenges when LOTO is executed. Practical misconception: A personal lock does not mean that each person has only one lock. Some friends can't figure it out: "Providing all LOTO authorized employees with personal exclusive locks and keeping only one key", does it mean that each authorized employee has only one lock? No, during the inspection and maintenance process, an open working environment is often encountered, and there are multiple energy cut-off devices in the system. There must be as many locks as there are locking points. For instance, if a production line has two energy locking points at the front and back, when one employee implements LOTO for the maintenance and upkeep of the production line, a total of two locks need to be added. In practical operation, having too many locks undoubtedly increases the cost and management burden of LOTO. More locks mean more unexpected situations and failure probabilities. Therefore, some factories will adapt to local conditions and change the "personal locks" to "post locks" for the regular inspection and maintenance of fixed production line workstations. They usually place the post locks at the fixed lock stations of the workstations.
