What we have written on the cold chain38 / 154

Isolate the faulty container by ID, set its lid as model and site instructions require, and record its holding condition at shift handover.

Duration bands make events easier to compare. Define boundaries and include logging intervals and gaps in the report.

Plan with usable stock whose quarantine reason and release evidence are known, not physical totals.

Product requirements and evidence duties do not disappear when the main carrier outsources work.

Leaving units randomly between loading and departure creates sun, heat-source, impact and wrong-vehicle risks.

Assessing every trip alone hides gradual performance change.

Link damage location, container ID, product waiting state and spare readiness records in one event file.

Identify the event by container, lot, time and measurement point; track decision owner and notification acknowledgement.

When the drop-off point and the signature desk are apart, identity checks and visible damage get missed; a station brings the record and the container together at one point.

A maintenance schedule says what will be done, a maintenance card says what was done. Without the second, the first is a statement of intent.

Record the ID and fault, isolate the container under the site SOP, and keep it out of use until an authorized technical decision.

The same average can hide different record completeness and route mix. Match runs first, then review the distribution.
