Correct use of Lockout tagout procedures
First of all, the HSE (health, safety and environment) department or maintenance management department of the enterprise should develop detailed hazardous energy control procedures. Secondly, staff including equipment maintenance and equipment operators should be trained in the knowledge of hazardous energy, hazardous energy injury cases, hazardous energy control procedures, Lockout tagout process, appliance use methods, etc. And all maintenance personnel and part of the equipment operators in need of Lockout tagout authorization, as well as Lockout tagout process card, equipment issuance. Third, the establishment of hazardous energy isolation measures for the equipment in the enterprise. Fourth, the implementation of dangerous energy requirements are also different, so the design should consider the two kinds of weld, as well as the accessibility requirements of the scanning direction. Because the in-service inspection accessibility requirements of this weld were not fully considered in the initial design, it is necessary to change the length and structural arrangement of the fluctuation nozzle, the safety relief nozzle and the safety end, so as to meet the requirements of the in-service inspection accessibility of the weld again. Although such changes meet the accessibility requirements of nozzle welds, they fail to comprehensively consider the length size of the fluctuating pipe in the initial design, resulting in a certain size overlap between the fluctuating pipe and the pipe. As a result, design changes to meet accessibility requirements may affect related equipment and pipelines. Therefore, the form of design should be considered comprehensively to meet the accessibility requirements, but also to maintain the reliability and integrity of the equipment.
