Lockout/tagout at the work site is a crucial procedure in safety management. It is mainly used during equipment maintenance, repair or cleaning. By isolating the energy source and marking warnings, it prevents accidental startup or energy release, thereby ensuring personnel safety and equipment integrity. Lockout/tagout is not only a "prescribed action" It is even a direct means to eliminate risks through engineering control. According to statistics, compliance with Lockout/tagout can reduce mechanical-related accidents by approximately 30%. Enterprises should regard it as the core link of safety management rather than a simple process burden. 1. Preventing misoperation: By installing locks and tags on equipment or energy isolation devices, clearly informing personnel that the equipment is under maintenance or shut down, it prevents other personnel from starting the equipment or operating the energy switch unknowingly, thus avoiding safety accidents caused by misoperation. 2. Protecting the safety of workers: It can ensure that during equipment inspection, maintenance and other operations, energy is reliably isolated, preventing accidental power-on, gas supply or startup, providing a safe working environment for workers and reducing the risk of accidental injury. 3. Standardize work procedures: The Lockout/tagout system in the "Three Regulations and Two Musts" system requires that operations be carried out in accordance with the prescribed procedures before work, clearly defining the responsibilities and steps of each link. This helps standardize work behavior, making the work process more rigorous and orderly, and enhancing the safety and reliability of the work.
