Having dry-ice and plate-cooled containers on one vehicle is not automatically suitable for every product or carrier. Verify the plan against product instructions, packaging, transport mode and vehicle-operator conditions.
Confirm acceptance before dispatch
Obtain current instructions from the product owner and carrier for dry-ice use, packaging, declaration, marking and handoff. Check the vehicle maker's or operator's current dry-ice requirements; determine ventilation and staff-training steps from that scope.
CDC's US laboratory safety guidance says dry ice should not be kept in sealed containers and carbon dioxide can accumulate in poorly ventilated vehicles. Before dispatch, confirm the ventilation setup and driver check with the vehicle operator; this guidance is not universal Turkish transport law.
Keep the dry-ice load separate from the plate-cooled load in a compatible, identified container; do not combine two cooling sources in one container unless a validated procedure explicitly permits it for the product and equipment. Open separate product, lot, method and sensor records for each container.
Reconcile records after the trip. Record dry-ice quantity loaded, container ID, start and arrival condition; for plate-cooled containers, record plate type and preparation state. Link door openings, delays or alarms to their times. Isolate a lot and obtain an authorized decision if suitability is in doubt; do not use a universal dry-ice quantity, safe duration or product outcome.
