What we have written on the cold chain17 / 154

Separate dirty, in-wash and clean statuses; manage transfers at the boundary defined by equipment and site cleaning SOPs.

Total plate count can hide timing bottlenecks. Match run demand, ready stock and freezing entries by day and hour; take model limits from its manual.

Separate purchase and actual replacement, search and extra-route costs per loss; do not present estimates as incurred costs.

Compare seasons on the same route, load and delivery conditions. Record ambient exposure, waiting, preparation and measured energy together.

Record open time, cartons removed and batch outcome at each stop; leave product disposition to the authorised process.

Check issuer, product scope, system boundary, method, date and validity; do not treat a general certificate as proof of product footprint.

Match return, cleaning, freezing and readiness by plate type and product code; do not treat all plates as one cycle group.

Review plans against actual trip and dwell records, not averages alone; match delay causes to temperature profiles.

A temperature event alone is not product loss. Define period, scope and actual disposition inventory; leave product decisions to the authorised process.

Record function checks separately from cleanliness and product suitability; verify return authority in the model instructions and site SOP.

Raw damage counts hide differences in use. Divide by cycles from the same scope and period, separating event type from discovery time.

For packaging placed on the EU market, verify scope, dates and evidence against your business role.
