Shipment Arrived Warm? How to Check and Prove What Happened to the Temperature

1. Preserve the original logger file

Keep the original logger export exactly as received. Do not rename columns, delete readings or overwrite the source with a spreadsheet edit. Work from a copy if you need to inspect it.

2. Keep the shipment and delivery context

Record the shipment identity, dates, origin and destination, delivery time, handover details and any known refrigeration or storage stages. Temperature readings are much easier to interpret when the observation window can be tied to the journey.

3. Find the actual temperature specification

If a customer, contract, product specification or other documented requirement states a temperature threshold, preserve that source. Do not substitute a generic number simply because it sounds typical.

4. Read the full temperature journey

One isolated reading rarely explains the event. Look at when the temperature changed, how long it stayed elevated, the peak, and whether it recovered before delivery. Duration, peak and recovery provide more context than the maximum reading alone.

5. Preserve instrument and calibration context

If the logger has an individual calibration certificate, device serial, sensor identity or other instrument record, keep it with the source data. Missing calibration context should be reported as a limitation rather than filled in by assumption.

6. Separate evidence from conclusions

A warm arrival does not by itself establish exactly when an event occurred, who caused it, whether the goods were safe, whether a contract was breached or whether an insurer must pay. Those conclusions may depend on other facts, specifications and professional advice.

What GCCAP adds

GCCAP can preserve a supported source file, reconstruct the observation period, summarise excursions, keep limitations visible and produce a sealed temperature evidence report with source and report integrity fingerprints.

GCCAP reports observed temperature evidence and limitations. It does not certify food safety or legal compliance.
