What is a PSSR safety review before driving? Is a dedicated review unit required?

Pre-Startup Safety Review

The safety checklist is an important basis in PSSR reviews, and its effectiveness determines the final outcome of the review. Therefore, certain issues need to be given special attention during its use, such as: (1) Developing an appropriate PSSR checklist – different projects require different checklists, and it is necessary to create a suitable PSSR checklist based on the actual conditions of each project. Depending on the size of the project, the extent of equipment changes, as well as the company’s safety management level and the implementation of various systems, the contents and scope covered by the PSSR checklist also vary. When the changes to the device are minor and the risk is low, the PSSR checklist is relatively simple and short, and vice versa. (2) Thorough understanding of the inspection items in the checklist: During the PSSR audit process, it is crucial for the members of the PSSR team to fully understand the meaning of the inspection items listed in the checklist, to recognize the differences between PSSR and previous completion inspections and safety checks, and to determine effective inspection methods. This is of great significance for improving the overall quality of the PSSR audit. In practical applications, there are two methods through which inspectors’ understanding and awareness of the inspection requirements can be improved, as follows: ① Strengthen the training of PSSR team members to deepen their understanding and knowledge of PSM and PSSR, thereby enhancing their ability to carry out PSSR ； ②The \"PSSR Review Guidelines\" were developed to provide an explanation for each item on the PSSR checklist, clarify the meaning of the relevant provisions, and determine the directions and key focus areas for the audit. (3) The inspection process must be thorough and meticulous. When conducting a PSSR review using a safety checklist, it is essential to carry out a careful inspection on-site or conduct a document review, checking each item listed in the safety checklist one by one. Regarding the issues identified during the process, the review panel must conduct an objective and fair assessment, and must avoid being presumptuous or drawing generalizations based on partial information. Once the PSSR team reaches a consensus, the corrective actions are identified; these actions are classified into those that must be carried out immediately and those that can be addressed later, and they are monitored and implemented to ensure the safe startup and operation of the project. The contents of the PSSR safety checklist are not fixed; they need to be adjusted according to the actual conditions of the project. When using a safety checklist, it is necessary to take into account the actual management conditions on site, thoroughly understand the relevant provisions, and conduct a thorough and meticulous check of each item in a realistic manner.

The safety checklist serves as the standard and basis for the Pre-Operation Safety Review (PSSR), and the quality of its preparation directly affects the final outcome of the safety review. Therefore, when preparing a safety checklist, comprehensive consideration is required to meet the following requirements: (1) Appropriate staffing – PSSR covers a wide range of areas such as process safety information, mechanical integrity, process hazard analysis, and fire protection; it is difficult to handle all these aspects relying solely on the expertise and experience of one or two people. The content of the PSSR safety checklist must be developed through consultation among technical experts from various specialized fields and safety managers with extensive practical experience, in order to ensure its professionalism and comprehensiveness. (2) Adequate preparation: The items to be checked in the PSSR safety checklist should be formulated based on the actual conditions of each enterprise and each project installation. For different facilities, the requirements for PSSR reviews vary due to the specifics of their production processes, products manufactured, and production equipment. Moreover, for the same type of facility in different companies, the contents of the PSSR safety checklists also differ, as safety management levels vary from one company to another. Before preparing the PSSR safety checklist, the preparer should, based on a thorough understanding of the company’s safety management system as well as the implementation of safety management procedures and policies, conduct on-site inspections of the project or facility, collect relevant technical information, and gain a deep understanding of the process flow of the facility in question as well as the technical characteristics of its production equipment. Based on the actual conditions of the project, a PSSR safety checklist that meets the project’s requirements should then be developed. (3) Proper application of relevant laws, regulations, standards, and specifications. The basis for conducting inspections using the PSSR safety checklist are the relevant laws, regulations, standards, specifications, and rules and regulations at the national, local, and industry/enterprise levels. China’s technical standard system is relatively complex; it can be divided into **national standards, industry standards, local standards, and enterprise standards** based on hierarchy ； Based on the applicable entities, they can be divided into general standards and specialized standards ； Based on their legal validity, standards can be divided into mandatory standards and recommended standards; moreover, different production facilities have varying standard requirements. When using the PSSR safety checklist to strictly implement laws, regulations, standards, and specifications related to inspection items, it is necessary to pay attention to the correctness and applicability of relevant standards, as different standards apply to different inspection items. (4) The review content should be comprehensive and systematic, easy to understand, with emphasis on key points. The PSSR safety checklist covers a wide range of aspects in a comprehensive and systematic manner, with review items including process technology, equipment, environmental protection, safety management, and more. At the same time, the contents of the safety checklist should be clear and easy to understand, with well-structured clauses that highlight the key points for inspection, facilitating verification by the PSSR team members. This helps to avoid including concepts that make objective judgment difficult, as well as repeated or similar inspection items in the verification clauses. The above content outlines the requirements for preparing a Pre-Startup Safety Review (PSSR) checklist, covering aspects such as staffing, key elements, the applicability of laws and regulations, and tasks during the preparation phase. Each requirement is based on practical experience and serves as an important guide for companies in developing safety checklists.

Checklists are the most important and core element of PSSR, but they are also the most difficult, as they require specificity. Headache

Look on the third floor; CNPC has complete sets of inspection forms that can be used as a reference

Studying*, studying* – this is quite important.

In fact, it is a comprehensive joint inspection by various departments prior to driving, which is more extensive than the three inspections and four fixations

No matter what the examination is, the key is to carry it out carefully and responsibly.
