What we have written on the cold chain90 / 154

Segregate lots exposed to smoke or heat. Decide on product acceptance and equipment reuse under authorised procedures.

Record a baseline with the same load and delivery conditions; change one factor and measure again.

The question to ask before buying more containers: how much of the day do the current ones work. The ratio is container-hours dispatched divided by container-hours available.

Name trip files with identifiers, keep an independent backup and verify that a sample file can be restored.

Match trip ID, measurement point, device and timestamps. Route deviations and data gaps to the authorised owner under product instructions.

A lid sensor may show event timing; it cannot alone prove product temperature or the cause of a deviation. Match it with other records.

Assign each returnable container one ID; reconcile its location against shipment and movement records, then resolve mismatches by count.

Agree shipment and device IDs, measurement point, period and file format in advance. Limit raw-data access to customer scope and permissions.

Segregate an out-of-service container and record the reason and repair assessment. Verify reuse, sale or disposal route under authorized procedures.

Link acceptance, route use, measurements, cleaning and fault records to the equipment ID from day one.

Check coverage in the warranty and sales contract; link installation, maintenance and fault evidence to the serial number.

Trial the first batch on a representative route; base expansion on measured acceptance criteria and comparable quotes.
