Research On Safety Announcement And Operation Permit Of Equipment Inspection And Maintenance Operation In Iron And Steel Enterprise

Inspection and maintenance activities of iron and steel enterprises refer to activities other than the main processes of ironmaking,steelmaking,steel rolling,etc.The biggest difference between it and conventional production operations is that due to changes in the operating environment,operating content and tools used,the corresponding Safety risks will also change;and due to the characteristics of iron and steel enterprises,in the process of inspection and maintenance of their equipment,due to the long maintenance time,the complex composition of personnel involved in the maintenance and the harsh working environment,etc.,the inspection has also been greatly improved.The safety risks in the maintenance operation process have brought great difficulties to the safety disclosure and operation permits of the inspection and maintenance operations.Due to the complexity of traditional safety disclosure and operation permit safety risk control measures,they cannot play their due role.It brings great inconvenience to the safety management of the inspection and maintenance work site.In order to effectively control the risks caused by the safety of the inspection and maintenance operations and the difficulty of the operation permit in the iron and steel enterprises,first of all,combined with the characteristics of the inspection and maintenance operations and risks of the iron and steel enterprises,based on the principle of risk management,the JHA analysis method is used according to the inspection and maintenance activities.The characteristics of the hazard factors are refined to achieve a comprehensive,systematic and accurate identification of safety risks and their hazards,and to supplement and improve existing control measures to control the risks in an acceptable state,thereby forming a comprehensive and effective "steel Safety Risk Information Sheet for Enterprise Inspection and Maintenance Operations".Secondly,based on the "Safety Risk Information Sheet for Inspection and Maintenance Activities of Iron and Steel Enterprises",based on the factors that cause safety risks in inspection and maintenance operations,on the basis of not missing safety risks and avoiding safety disclosures and operating permit safety risk control measures,the content is too complicated.The safety risk information was subdivided,and the following four safety risk management and control knowledge bases were formed: "Inspection and maintenance tool safety risk information database","Inspection and maintenance operating environment safety risk information database","Operation activity itself safety risk information database","Special Operation Safety Risk Information Database".Finally,in order to be able to enhance the storage,sharing,transmission of data and information involved in the use of security disclosures and operating permits,as well as to improve work efficiency and standardize the management process,the four security risk management and control knowledge bases can be selected and combined to complete the establishment "Information Management System for Safety Interpretation and Operation Permit of Steel Enterprise Inspection and Maintenance Operations".
