Fermentation Heating Tube Anti-Corrosion Archive Centralized Management & Data Security Specification

# Anti-Corrosion Archive for Fermentation Heating Tubes Centralised Management and Data Security Specification ## Introduction The entire anti-corrosion document system, which encompasses Doc.33 to Doc.106, is supported by this specification. It establishes unified management rules for the centralised filing, classification storage, access authority control, data backup, confidentiality protection, and expired file disposal of all anti-corrosion paper archives and electronic data. It guarantees the integrity, security, and traceability of all anti-corrosion management materials, thereby preventing risks such as file loss, unauthorised manipulation, confidential production data leakage, and disorderly discarded records. For the purpose of differentiated authority administration, all anti-corrosion archives are classified into four confidential grades. Standardised operation SOPs, public training courseware, and cross-workshop exchange materials are all included in the general public files. These files are accessible to all on-site staff with basic work authority. Daily patrol ledgers, maintenance records, monthly statistical reports, and routine audit documents are only accessible to production, maintenance, and workshop management personnel in the internal working archives. Before being viewed, confidential archives necessitate approval from factory equipment supervisors. These archives include cost-benefit analysis data, equipment transformation bidding documents, fault accountability materials, and third-party audit reports. Full-system acceptance reports, new production line anti-corrosion design drawings, and long-term core optimisation schemes are among the top-secret archives that are restricted to senior factory management and designated technical engineers. The "unified centralised archive management department" is the designation of the apparatus management department. A clear index catalogue is affixed outside each cabinet, and paper files are stored in special filing cabinets that are moisture-proof, fire-proof, and dust-proof. The cabinets are classified by serial document number, year, and workshop. The factory's dedicated encrypted cloud server is where electronic anti-corrosion data is stored. The server is designed with independent file folders that correspond to each serial specification and are designated in a unified, standardised format to facilitate rapid retrieval. In order to promptly update damaged electronic files and supplement absent documents, all physical and electronic archives must be counted and inspected on a quarterly basis. The procedures for access and borrowing are rigorous. In order to temporarily view paper archives on-site, staff members must register personal information, the purpose of the viewing, and the file serial numbers without removing the files from the archive room. It is necessary to submit a formal borrowing application form with the department supervisor's signature in order to borrow archives off-site. The borrowing period is limited to seven working days, and overdue borrowers are prohibited from reapplying for archive borrowing until all materials have been returned. The system automatically records all viewing, downloading, and printing traces for permanent tracking, prohibiting the unauthorised copy and transmission of confidential data through mobile storage devices. Electronic archives can only be registered in through exclusive personal work accounts. In order to mitigate data loss, dual backup mechanisms are implemented. The automatic daily cloud backup and weekly offline hard disc backup of electronic anti-corrosion data are completed. The two sets of backup storage media are located in distinct fire-proof areas. Simultaneous preservation is achieved by scanning paper key archives into electronic versions. The archive team sorts out expired records, submits a unified disposal application to the equipment department, and uniformly shreds invalid paper files and permanently deletes redundant electronic copies after approval, with complete disposal records being retained, when files reach the retention time limit of three years. The archive index catalogues, backup logs, quarterly inventory records, expired file disposal documents, and borrowing registration forms are all preserved independently. This specification establishes a comprehensive security control system that encompasses archive collection, storage, access, and disposal. It also protects the data foundation of the entire heating tube anti-corrosion closed-loop management system and offers comprehensive, secure, and credible file support for daily operation, audit inspection, and long-term system optimisation.
