Product and contamination information should show verified grades, loading dates, moisture events and the next intended use in sequence. Corrections retain their source and date so the cleaning decision can be reconstructed later.
The documents must match the product and grade actually stored. Superseded or unrelated information can lead the review in the wrong direction.
Current, previous and next materials
Put the verified product sequence on one record before the physical cleaning areas are discussed.
Keep gaps visible in the product history
Keep dates, grade changes and moisture events in order against the same vessel. If an entry cannot be verified, mark the gap and its source rather than filling it from memory. The uncertainty can then be resolved before a method or recovered-material route is chosen.
The stored material information sheet provides a working format. Use it when discussing powder silo cleaning or a cross-contamination risk.
Mark missing product information as unknown
Do not fill the gap with an assumption. Provide the records available and let the uncertainty form part of the job details review.
The site is responsible for providing accurate product and contamination information and following its safety, quality and approval procedures.
