Here is a set of maintenance record archiving precautions for clean rooms / GMP / audits that can be directly passed. It is simple, practical, and can be directly posted on the wall for execution:
Maintenance Record Archiving Precautions for Supply Air Ceilings – Archive Management Notes
1. Complete Archiving Scope
All daily inspections, cleaning, pressure difference monitoring, filter replacement, fault handling, verification records, and audit records must be archived completely. No selective retention is allowed.
Supporting materials should also be archived together: equipment ledger, filter certificate, pressure difference meter calibration certificate, maintenance SOP number.
2. Clear Archiving Classification
Archive separately by **”Workshop → Area → Equipment Position Number → Year”**. Each machine should have its own file. Do not mix with other equipment.
Paper Archives: Establish a directory + page numbers for quick retrieval.
Electronic Archives: Store according to a unified naming rule, such as:
Supply Air Ceiling – XX Workshop – Position Number – 2026 Annual Maintenance Record
3. Timely Archiving Deadline
Principle: Whoever records, whoever organizes, and archive on time.
Daily records: Archive once a week/month.
Annual archives: Complete binding and archiving within 1 month of the following year.
Prohibit long-term storage on-site, scattered storage, loss or damage.
4. Writing and Modification Specifications (Must be checked before archiving)
Clear handwriting, no alterations, no scribbling or drawing.
If modification is necessary: single-line deletion → rewrite → signature + date. Do not cover, scrape, or use correction fluid.
All operators, reviewers, and auditors must sign.
5. Storage Environment Requirements
Paper Archives: Dry, ventilated, protected from light, moisture-proof, pest-proof, rodent-proof, fire-proof.
Do not place in: clean area corridors, workshop corners, damp areas.
Electronic Archives: Dual backup in cloud + local, and check for readability regularly.
6. Compliance with Preservation Period
General industry: No less than 3 years.
Pharmaceuticals / Food / Clean Rooms: According to regulations or customer requirements, usually **≥3 years or long-term preservation**.
Do not destroy or discard prematurely.
7. Management of Borrowing and Review
Establish borrowing registration: Borrower, date, purpose, return time.
Originals are not to be borrowed or taken away. Copies are preferred for auditing / inspection.
Set permissions for electronic records to prevent accidental deletion or modification.
8. Audit and Traceability Requirements
Archived records must be traceable, reviewable, and verifiable.
In case of cleanliness not meeting standards, equipment failure, or customer audits, the corresponding records for the period can be quickly retrieved.
Strictly prohibit filling in, backfilling, or fabricating records for archiving.
9. Handling of Invalidated / Expired Records
Expired destruction requires approval, registration, and supervision of destruction.
Do not discard randomly as waste to prevent information leakage.
