Energy isolation "work requirements
"Most accidents in chemical enterprises are related to the accidental release of energy or materials. Therefore, in daily inspection and maintenance operations, the requirements of the company must be strictly followed to avoid accidental release of energy resulting in personal injury or property loss." In the special training course of energy isolation in the factory, the head of production technology department explained in detail the principle of energy isolation, the scope of application of lock tag, the management procedure of lock tag, lock equipment and storage requirements to the director in charge of process and technical personnel in the workshop. Since this year, the factory has implemented the Energy Isolation Management Measures of Jilin Petrochemical Company to strengthen on-site operation safety risk control.

However, in the process of implementing the management measures, there are still non-standard phenomena. In view of this situation, the factory has organized special training at the factory and workshop levels to improve the knowledge and skills of the cadres and employees on energy isolation. PBL workshop takes the energy isolation training as an important part of the activities of "great training, great training, great competition and great assessment". Through theoretical learning and on-site simulation operation, the staff can master the specific operation steps of energy isolation. The electrical workshop prepared the Implementation Plan of Energy Isolation in Electrical Workshop, and with this as the training focus, organized staff to explain the plan on site, which deepened staff's understanding of the plan. In addition to the energy isolation training, the mixing and packaging workshop also organizes the staff to watch the video of the energy isolation accident through the safety activities of the team and group, so as to warn and educate the staff to pay more attention to the energy isolation work.

G-abs unit stopped for maintenance for A short time. ABS workshop technician Shi Shengtao came to A substation and filled in the contact list of power stop and energy isolation list. Electrical workshop Zhao Zhongqiang cut off the power supply to the main motor of the vacuum filter. Later, Shi shengtao and Zhao Zhongqiang together to lock the low-voltage switch cabinet, and hang a label marked "danger, do not operate" and indicate who, when and other words. According to Shi shengtao, routine inspection and maintenance must first confirm that energy isolation measures are in place before construction is allowed. Especially for the operation of stopping power supply of electrical equipment, the factory requires local workshop and electrical workshop to Lockout and tagout the high and low voltage switchgear of the equipment at the same time. The factory organized personnel to make statistics on all the high and low voltage equipment in the factory, and formulated different management measures according to the actual situation of the equipment. If the condition of locking is met, the management of Lockout tagout shall be firmly implemented; if the condition of locking is not met, the management of hanging label shall be implemented, and the label shall be signed upon confirmation by the technician. When stopping power supply, the factory requires the local workshop to fill in the Energy Isolation Registration Form and the Electrical Energy Isolation List. When it comes to the opening operation of materials and public works pipelines, local workshops are required to make energy isolation plans in advance, complete the handover of single equipment and construction disclosure before construction, and take measures such as adding blind plates, closing valves and Lockout tagout to prevent the accidental release of dangerous energy and materials.
