化工安全论文2（Chemical safety thesis 2） Abstract: the operation of chemical equipment overhaul is complex, technical and risky. This paper analyzes the safety handling and behavior standards of chemical equipment during overhaul, and ensures that the equipment is put into operation again after being checked and maintained, so as to create favorable conditions for safe production. 1. Preface The chemical safety inspection not only ensure the safety of maintenance operations, to prevent major accidents, and protect the safety and health, but also can promote the repair job on time, quality and quantity to complete, maintenance work to ensure that the quality of the equipment, the equipment is put into operation, stable operation, high operation rate, prevent accidents and pollution of the environment, create a good the conditions for safe production. For this reason, it is necessary to do the safety technical treatment before and after the overhaul and the safety technical treatment before and after the shutdown. 2. safety control of parking before overhaul Once the parking plan has been determined, the parking schedule, step 4345, process variation range, and confirmed parking schedule shall be carried out in an organized and orderly manner in strict accordance with the parking plan. On the one hand, the safety of production can be affected; on the other hand, it will affect the safety of the maintenance operation and the quality of safety inspection. The main safety technologies for device shutdown are as follows: 2.1 parking in strict accordance with the scheduled parking plan Maintain close contact according to the maintenance plan and the upper and lower processes and relevant sections (such as boiler room, power distribution room, etc.), and strictly stop the operation of the equipment in accordance with the procedures stipulated in the parking plan. 2.2 the pressure should be slow and moderate The relief operation shall be carried out slowly and shall not be dismantl
