Full Lifecycle Training & Competency Qualification Specification for Fermentation Heating Tube Anti-Corrosion System

# Full Lifecycle Training & Competency Qualification Specification for Fermentation Heating Tube Anti-Corrosion System (Doc.75) ## Preface Documents No.33–72 comprise a comprehensive closed-loop anti-corrosion management system that encompasses corrosion theory, on-site operation, maintenance inspection, risk early warning, supervision audit, document archiving, and supervision enforcement. Document 75 implements a hierarchical competency assessment, post-qualification certification, training archive traceability mechanism, standardised teaching content, and stratified training system for all personnel involved in the operation and management of heating tubes. It eliminates the prevalent issues of inconsistent staff anti-corrosion awareness, unstandardised operation, uneven mastery of standards, and ambiguous competency thresholds, and it guarantees the human resource for the complete implementation of the entire anti-corrosion management system. ## Chapter 1 General Training Management Rules ## 1.1 Personnel Classification & Training Responsibility Division 1. Type A: Frontline operators who have been recently recruited (fermentation/CIP post) Responsible department: Production workshop + equipment team Training core objective: Completion of the second independent duty assessment, mastery of basic operation anti-corrosion SOP, risk identification, and simple emergency disposal. Type B: In-service shift operators (regular retraining)…Responsible department: Shift foreman + equipment supervisor Training core objective: Consolidate standard operation, acquire knowledge of new failure cases and revised document clauses, and eliminate prohibited misoperations 3. Training core target: Master material matching, standardised disassembly/assembly, gasket management, post-overhaul anti-corrosion requirements, predictive testing operation specifications 4. Type C: Equipment maintenance & overhaul personnel. Responsible department: Workshop equipment management team. Type D: Shift foremen and equipment supervisors (management execution layer) Responsible department: Production management department + factory equipment department Training core target: Comprehend full-system lifecycle management, risk hidden danger closed-loop rectification, audit supervision standards, KPI assessment management, accident root cause investigation methods 5. Type E: Workshop directors and factory equipment auditors (decision and audit layer) Responsible department: Factory management department Training core target: System overall optimisation logic, hardware transformation planning, major risk emergency command, cross-departmental audit & accountability standards ## 1.2 Training Frequency Mandatory Standards 1. No independent operation is permitted without certification 2. Mandatory 24 class hours of centralised training for new staff members prior to assuming their positions. Frontline operator monthly regular training: A minimum of two class hours per month, with a fixed monthly anti-corrosion case training session. Maintenance personnel undergo professional skill training on a biweekly basis, with a 1.5-hour session scheduled every two weeks. The training includes disassembly, testing, and consumable management. Management personnel undergo quarterly advanced system training, which occupies four hours and encompasses the implementation of optimisation plans, accident investigations, and audits. Full-staff special emergency training: Occurs every six months and simulates red major risk abnormal disposal (e.g., heating tube leakage, filter full failure, alkali/fluoride cross-contamination).6. Temporary supplementary training is initiated by the following conditions: - The release of a new anti-corrosion document version; - A serious heating tube corrosion failure accident occurs in the factory; - A large-scale pipeline transformation of hardware is conducted, resulting in the implementation of new heating tube material; - A quarterly factory audit identifies repeated non-conformities in a large area. ## 1.3 Fixed Training Teaching Materials Library (Unified Teaching Basis) The unified standard materials in the integrated bound volume Doc.68 shall serve as the primary textbook for all training. Supplementary supporting materials may include: 1. Core standard documents: operator SOP (Doc.59), lifecycle management, risk prevention manual, and corrosion hazard analysis (Doc.33–64).2. Management execution documents: Doc.58 accident investigation, Doc.60 KPI indicators, Doc.62 optimisation plan, Doc.70 audit specification, Doc.71 archiving traceability rules 3. Auxiliary teaching materials: Accident video records, patrol checklists, test report templates, hidden danger rectification cases, on-site heating tube corrosion failure physical samples. Differentiated handouts: Simplified handouts that are categorised for operators, maintenance workers, and management staff. # Chapter 2 Tiered Differentiated Training Content Framework ## 2.1 Level 1 Training (Frontline Operators Type A/B) ### Theoretical Module (Basic Anti-Corrosion Knowledge) 1. 2. Absolute forbidden operations and core protection characteristics of four heating tube materials. Identification of early corrosion abnormal signs in stainless steel, titanium, PFA, and quartz.

Chapter 3 Standardised Assessment & Post Qualification Certification System ## 3.1 Two-in-One Assessment Mode: Written Theory + On-Site Practical Operation ## 3.1.1 Written Examination Content Rules 1. Operator written exam: Extract all test questions from the operator SOP in Doc.59 and the risk prevention manual in Doc.64. The full score is 100, and the pass score is ≥90 points. Written test for maintenance workers: Include questions regarding material matching, testing operations, and maintenance standards. A passing score of 85 points is required. ## 3.1.2 On-Site Practical Assessment Items 1. Management staff written test: Cover accident investigation, audit, KPI, risk rectification, and system management clauses, pass score ≥80 points. Operator practical test: Simulate the setting of CIP parameters, the identification of abnormal corrosion signs during patrols, the control of static standby timing, and the disposal of simple parameter abnormalities through parameter dilution. Maintenance practical test: Monthly potential scanning test operation demonstration 3, gasket classified matching, filter disassembly cleaning, standard flange disassembly and assembly. Management practical assessment: On-site hidden danger identification grading, filling of the hidden danger rectification journal, and simulating the accident root cause. ## 3.2 Graded Qualification Certification Mechanism 1. Primary Qualification Certificate (Frontline Operator): Awarded upon successful completion of the Level 1 assessment, this certificate is valid for six months. Applicants must retake the assessment prior to its expiration, and they are unable to work independently without a valid certificate. Intermediate Qualification Certificate (Maintenance Worker): Successful completion of Level1+Level2 assessment, which is applicable for 12 months, is a requirement for conducting heating tube overhaul work. Advanced Management Qualification Certificate (Supervisor/Foreman): Successfully complete the Level 1+2+3 assessment, which is valid for 12 months. This certificate is a prerequisite for the anti-corrosion audit and hidden danger supervision work4. Senior System Qualification Certificate (Workshop/Factory Manager): Successfully complete a comprehensive four-level training and assessment, which is valid for 24 months. This certificate is awarded to individuals who are responsible for the optimisation of the overall operation of the anti-corrosion system. ## 3.3 Assessment Failure Disposal Rules 1. First failure: Schedule an additional eight hours of training within three business days and participate in a second make-up examination. 2. The second consecutive failure necessitates the suspension of the autonomous post operation, the coordination of comprehensive retraining, and the deduction of the monthly shift performance bonus. Unqualified for repeated assessment: Transfer from positions related to heating tube operations following adjustments. ## Chapter 4: Training Archive & Competency Traceability Management ## 4.1 Personal Electronic Training File (One File Per Person, Permanent Archive) Mandatory archive contents for each employee: 1. 1. Basic information, post type, and training level; 2. Attendance record for pre-employment training and receipt for approving the training handout; 3. Training video sign-in documents, as well as all monthly/quarterly regular training attendance forms; 4. Written examination papers, on-site practical assessment scoring sheets, and records of the issuance and renewal of qualification certificates; 5. Supplementary training records that are initiated by accidents, audit non-conformities, and document version updates; 6. Records of rewards and penalties associated with the performance of training and anti-corrosion operations. ## 4.2 Workshop Monthly Training Summary Archive The equipment management office generates a monthly training summary report that comprises the following: 1. Total training man-hours of each type of personnel, training schedule execution completion rate; 2. All personnel assessment pass rate statistics, a list of unqualified personnel, and supplementary training arrangements; 3. The typical incorrect question categorisation in the assessment, which is the focus of the training optimisation plan for the upcoming month. Training effect monitoring: Comparison of the frequency of forbidden misoperation occurrences before and after training, as well as the monthly anti-corrosion KPI compliance rate. Doc.71 document archive materials are archived and bound with all monthly reports, with a retention period of three years. ## 4.3 Training Traceability Audit Standard Auditors shall randomly select staff for on-site oral spot checks of anti-corrosion standard clauses during the factory quarterly cross-audit and verify personal training files: 1. Class B general nonconformity will be assessed in the event that training records are missing or qualification certificates have expired. This is classified as a Class A major non-conformity, necessitating the retraining of the entire staff within one week, as multiple staff members fail the oral spot check and lack complete supplementary training records. # Chapter 5: Training Incentive & Restraint Mechanism ## 5.1 Training Reward Rules 1. Individual small performance reward and public recognition on workshop bulletin board for all staff with full attendance and full score in monthly training assessment; 2. Shift collective anti-corrosion bonus: 100% assessment pass rate for the shift for the past six months; 3. Staff who actively share anti-corrosion failure cases and optimise operation suggestions during training: Priority in promotion evaluation, recorded in personal performance file; 4. Maintenance workers and supervisors who successfully complete advanced qualification certification on time will receive a monthly post-competency allowance. ## 5.2 Training Accountability Penalty Rules 1. Failure to attend mandatory regular training without legitimate leave will result in a written warning, a deduction from the daily performance wage, and mandatory make-up training during off-hours. Skip the training assessment or cheat in the written test intentionally: Serious criticism, a one-week suspension following retraining, and a double performance deduction. The team management KPI score is deducted, and a rectification training plan must be submitted within three days. This is due to the failure of management personnel to organise training as scheduled, resulting in a low aggregate post qualification pass rate. # Supplementary Provisions of Chapter 6 1. The comprehensive set of anti-corrosion system documents No. 33~72 shall be matched and implemented in conjunction with this Doc.75. The unified specifications of this document shall govern all training content, assessment standards, and qualification thresholds. 2. The workshop equipment management office is responsible for the daily implementation of training organization, archive sorting, and qualification certificate management. The factory production and equipment departments conduct quarterly supervision and spot checks on the effectiveness of training execution. 3. Supplementary special training must be conducted within one week of the revision of significant anti-corrosion documents or the emergence of new heating tube corrosion failure modes. The corresponding assessment questions must be updated synchronously. 4. For the purpose of factory audit traceability, all training attendance, assessment papers, personal competency files, and monthly training summary reports must be archived for a minimum of three years and dual-backed electronically and on paper. ## Summary Doc.75 establishes a closed-loop, tiered, and full-staff anti-corrosion training and competency qualification system that encompasses pre-job training, regular retraining, special emergency training, layered differentiated teaching content, dual theory-practical assessment, and lifelong personal competency file traceability. It addresses the fundamental hidden danger of insufficient personnel anti-corrosion awareness and unstandardised operation at the source of human factors, establishing human resource support that is aligned with the hardware transformation, process interlock, inspection audit, and risk prevention links of the entire anti-corrosion system. This fundamentally reduces human-induced forbidden misoperations and guarantees that all on-site personnel can accurately and consistently implement all anti-corrosion management standards in the Doc.68 integrated bound volume.
