"Previously, when repairing equipment, we only focused on turning off the power supply. Now we have come to realize that 'lockout tagout' provides a 'double insurance' for life." At the city-wide promotion and training session for the "lockout tagout" system, the safety director of a manufacturing enterprise, Mr. Wang, held the exclusive lock and completed the entire process of "identifying energy sources - isolating with lockout-tagout warning" through simulated operations. Recently, our city issued the "Implementation Plan for Comprehensive Promotion of the 'lockout tagout' Safety Management System for Mechanical Equipment", and has fully implemented this system in key industries such as industry, manufacturing, and agricultural machinery, to promote the transformation of safety governance from pre-event prevention to strict regulations, using "small locks" to safeguard "big safety". 

Policy Leading: Standardization System Solves Practical Problems

"More than 90% of mechanical maintenance accidents are caused by omitting the basic process of lockout and tagout." The person in charge of the emergency management bureau at the promotion meeting stated that previously, some enterprises had problems such as unstandardized operation procedures and unclear responsibility divisions, which led to frequent safety accidents caused by incorrect operations. To solve this problem, our city based on the actual situation of enterprises and constructed a standardized system of "template for systems + operation norms + responsibility loop". 

In the system design, the core principle was clearly defined as "who operates, who locks, who unlocks", and the seven-step operation method of "accurately identifying energy sources - shutting down the machine - machine isolation - placing lockout-tagout devices - storing energy - isolation verification - unlocking lockout-tagout devices" was implemented. Each link was made clear and orderly. In terms of hardware specifications, the lock must be marked with the name and contact information of the operator, and the must clearly fill in the equipment name， the date of locking， and the reason for the operation， implementing "one person one lock， dedicated lock for dedicated use"， and strictly prohibiting multiple people from sharing the lock to ensure that the operators independently control safety. According to the characteristics of different industries， special guidelines for five application scenarios such as high-voltage electrical equipment， mechanical equipment， and agricultural machinery equipment have been subdivided， allowing enterprises to directly refer to and implement them. 

Full-scale Promotion： Three-Dimensional Training Drives Standardization into Mind and Heart

"This lock should be fastened to the main power switch， and the key must be kept by oneself. The position should be conspicuous， so that others can see it at a glance." At the practical training site in the industrial park， the safety expert demonstrated and explained while conducting practical drills for lock operation， filling， etc.， by groups of trainees. To ensure the implementation of the system， our city innovatively carried out "three-level training - entering enterprises， entering workshops， entering positions"， using a "three-in-one" model of policy interpretation， case warnings， and simulated operations to ensure that front-line workers truly understood and mastered it. 

During the training， typical cases such as the death of a tractor repair worker in Huai'an and being fined 350，000 yuan for not hanging the during live electrical work were analyzed in detail. Using "the lesson of blood" to sound the safety alarm. As of now， our city has organized 28 special training sessions， covering 830 enterprises and training 12，000 workers， distributing 3，000 sets of standardized locks and 5，000 copies of operation manuals. "Previously， I thought the process was cumbersome， but now seeing the accident cases， I understand that every step is to save lives." The maintenance worker， Old Li， who just completed the training， said that now， locking and tagging before operation has become a "rigid rule" for the team.
