Safe dry-ice packing needs control of handling hazards and CO₂ gas release as well as product temperature. Use a container intended for the application, follow the supplier’s handling procedure and preserve the package’s gas-release design. Insulation or a compliant-looking sticker alone is not a complete safety check.
Prepare the work area and handlers
Plan storage and packing in an appropriately ventilated location. Keep dry ice out of uncontrolled enclosed spaces, and follow the site’s procedure for access, storage and exposure risks. CDC: dry ice exposure and ventilation documents illness from CO₂ exposure in an enclosed vehicle.
Use appropriate cold-protective handling equipment and protective measures specified by the supplier and workplace procedure. Avoid bare-skin contact. UPS: handling and shipping dry ice describes dry-ice handling protection and the need for appropriate training.
Check compatibility before loading
- The manufacturer permits dry ice in the exact container.
- The liner, separators and primary packages tolerate the intended exposure.
- The product is suitable for the proposed cold conditions.
- The gas-release arrangement remains functional after closure.
- Outer protection does not defeat that arrangement.
- The operator can assemble the design consistently.
Do not assume all plastic coolers or soft bags tolerate the same application. Do not modify a container by drilling improvised vents and present it as an approved shipping system.
Review the loaded package
| Check | Question before dispatch |
|---|---|
| Dry ice | Does actual form and loading mass match the accepted instruction? |
| Payload | Is the product prepared and positioned correctly? |
| Separation | Are contact risks and movement controlled by the specified components? |
| Closure | Does it provide intended protection without trapping CO₂? |
| Identification | Are category-specific markings and records complete and consistent? |
Sealing the contents against leakage and enclosing the coolant in an airtight vessel are different actions. Use suitable primary containment while preserving the dry-ice package’s gas-release design.
Assign safe handoff and receipt
Tell each responsible party what it is receiving and which handling instructions apply. The dispatch plan should cover collection, any permitted intermediate handling and the receiver’s access to the appropriate procedure.

For applicable US air or water shipments, 49 CFR 173.217: carbon dioxide, solid establishes gas-release packaging requirements. The carrier’s acceptance process and workplace safety controls both need attention.
Frequently asked questions
Can I seal the outer dry-ice box airtight?
No. The package must release CO₂ gas safely.
Does using newspaper prove the separator is suitable?
No. Use the specified compatible separator and assess the complete arrangement.
Can adding more dry ice change the safety plan?
Yes. It changes the amount offered, fit, gas generation and potential product exposure. Review the revised configuration and acceptance requirements.
