What we have written on the cold chain89 / 154

Build the checklist around product requirements and site procedures; assign an owner and evidence for each item.

Do not assume the source of odour; inspect removable parts, cleaning steps and verification records.

Add drying area, container ID and inspection to the wash record. Keep wet containers separate from clean, dispatch-ready stock.

Check labeled use, application instructions and rinsing conditions. Verify compatibility with the body, seal and contact surfaces.

Cold leaking past a gasket never shows on an invoice but sits in the temperature curve. The replacement interval comes from a check record tied to the container ID, not from a calendar.

Appearance alone does not prove hygiene. Record material compatibility, damage points and cleaning verification.

Record interrupted cycles and affected lots; verify manufacturer and quality acceptance before reusing plates.

Use stock, lead-time and usage records to identify stoppage-critical parts and validate a suitable backup.

Damage on the road forces two decisions: does the trip continue and can the goods be protected. A temporary fix never replaces a proper repair.

Look first for a spare set with the same melting point; if there is none, three routes remain: delay the trip, split the order or go out with dry ice.

Do not skip cleaning when water is unavailable. Segregate soiled carriers, verify an approved alternative and resume with records.

Maintain batch and movement traceability manually during an outage. Decide to continue or stop based on record capability and authorised procedure.
