What we have written on the cold chain13 / 154

A blank display does not mean the container cannot hold cold, but it cannot prove that it did. For quick-frozen food a recording device is a legal requirement; for other loads the buyer's contract decides.

Count repeats by container and part ID, work out the rate within a set follow-up period, then look for the cause.

A rejection closes under one code. Put the legal temperature limits next to the appointment and door-opening times and you can see where the loss actually happened.

Define the same functional unit and system boundary; use actual cycles adjusted for loss and early retirement, not planned life.

An unidentified container looks like spare equipment at a branch. A persistent number ties it to the trip, its last location and a responsible role.

A last-minute hold on an unready plate can affect waiting and sequence. Track batch, rack and verification records together.

One air sensor alone does not show product exposure or determine acceptance.

Read water volume alongside the wash programme, compliant assets and calculation boundary.

A missing castor or latch can idle a box for months. Service life depends on the parts plan and the ATP inspection calendar together; both are worked out below.

One suspect display does not establish product condition. Preserve the first reading, check its context and report the result to the authorized role.

Sum each container's repair days; show wait type and share of fleet to interpret capacity impact.

Cooling a warm body with goods and plates spends their capacity on the container mass.
