What is the importance of the permit system during the maintenance of chemical processing equipment?

First, the ticket design must meet regulatory requirements; second, the ticket management system needs to be evaluated in terms of its practical feasibility. Most importantly, the way tickets are issued doesn’t indicate anything; to ensure safety, it is necessary to implement safety measures in accordance with the requirements set out in the tickets and regulations. Meanwhile, personnel at all levels must take responsibility for signing off – they can only sign after confirming that all safety measures have been put in place, and signing signifies assuming that responsibility.

1. Standardize and strictly regulate the procedures for the maintenance of chemical equipment； 2. Chemical processing equipment is all classified as hazardous equipment that is flammable, explosive, and toxic; by strictly implementing a permit system, it is possible to enforce controls at all levels and in all aspects, thereby avoiding management gaps and ensuring safe maintenance work ； 3. To be retained as original records to serve as a reference for equipment maintenance.

Handling tickets mainly involves conducting hazard analysis, formulating safety measures, clarifying responsibilities, and signing to ensure that everyone fulfills their duties; it also entails carefully checking the implementation of these safety measures

The importance of the ticketing system: By using tickets, dangerous tasks during maintenance operations are strictly controlled, with safety measures being implemented step by step at each stage of the process.

The most important thing is to ensure that responsibilities are clearly defined, and that the tickets correspond to the actual situation of the company. The current regulations are not comprehensive enough; one can refer to the systems used by companies in Europe and the United States in this regard, as they are quite thorough.

Signing work permits is a system for granting operational authorization in this province. The process of issuing these permits involves defining the safety responsibilities of the personnel involved, conducting risk analyses, and implementing safety measures. The issuance of a work permit indicates that the risks associated with the task have been effectively controlled, thereby ensuring safe operations. Therefore, the significance of signing work permits lies in the collaborative effort of all relevant parties to ensure proper oversight.

The importance of managing work order sheets for chemical plant equipment maintenance lies in eliminating hazards associated with maintenance activities, taking appropriate preventive measures against potential hazards, ensuring that all personnel involved in the maintenance process fulfill their safety responsibilities, and thus preventing injuries to people and damage to equipment during maintenance. On December 30, 2009, a maintenance accident occurred that resulted in the death of four people, including the vice president of a certain company. In my opinion, this accident was caused by the failure to properly implement the work order system, and it serves as a serious lesson. The basic situation is as follows: An explosion occurred at Shanxi Huaguang Power Generation Co., Ltd. At 16:50 on December 30, 2009, during maintenance work while the unit was shut down on the 6.9-meter platform of Generator No. 4, an explosion of residual cooling gas (hydrogen) took place inside the generator hall. Five people were injured: Zhu Hongyong, the team leader of Shanxi Tongjian Power Equipment Installation Company who was in charge of this maintenance work, along with team members Kang Fujian and Hua Guang; Gao Yongliang, the chief engineer of Huaguang Power Generation Company; Lei Yongxing, a senior engineer; and Han Guangyu, an electrical engineer. They were taken to the hospital, where doctors determined that Zhu Hongyong, Kang Fujian, Gao Yongliang, and Lei Yongxing had died. Han Guangyu suffered burns and has been taken to Taiyuan Hospital for treatment.

The main **tasks, especially those related to chemical plant maintenance, are extremely dangerous. Strict adherence to procedural guidelines is crucial for ensuring safety during such maintenance activities

In my opinion, issuing work permits serves the following purposes: 1. To highlight the uniqueness and danger associated with the task, thereby raising the awareness of the workers, supervisors, guardians, and approvers and strengthening their consciousness. 2. Identification of hazards, assessment of risks, formulation of preventive and emergency measures – by issuing work permits, personnel at all levels follow the established procedures to control various factors, ensuring that these measures are properly implemented. 3. Strengthen the implementation of responsibilities by means of review and approval at all levels, so as to ensure that safety responsibilities are fulfilled and to enhance the safety awareness of personnel at all levels.
