Define storage classes before receiving
Set storage class requirements by material type before purchase orders are submitted. Receiving teams should not decide storage conditions ad hoc.
Document class requirements in a shared SOP table so procurement and lab operations follow the same protocol.
Track exposure windows during handling
Monitor the total out-of-storage handling window for each lot and annotate exceptions with timestamps.
Repeated short exposures can still create cumulative risk if teams do not capture handling history.
Use lot-level stability notes in protocol interpretation
Protocol logs should reference the lot history and any storage deviations that occurred before use.
Stability context improves reproducibility reviews when comparing results across study windows.
