There are two main problems in this issue. One is the sense of responsibility of staff when they go to work, practically implement the safety system, improve the safety quality of operators, and grasp the fundamentals of safety management. The other is that the equipment must be diligent in maintenance and inspection equipment must be comprehensive. The operating personnel must strictly implement the equipment patrol inspection system, inspect the equipment every shift, and immediately fill in the defect notice when the problem is discovered, and notify the leaders of the work area to request maintenance. The duty staff insists that the equipment be inspected on a regular basis every day, so that the equipment defects have nowhere to hide. Once the equipment is found to be defective, the maintenance class must be rushed to the site for processing as soon as possible. In principle, small defects cannot be overshifted, and large defects cannot be overdone. At the same time, whether it is a defect or an overhaul, the operating personnel and the maintenance personnel must inspect the equipment after inspection together. To ensure the quality of defects and maintenance.
