How do I store dry ice?

Store dry ice in an insulated container to slow sublimation. The best options depend on volume:

• Small volumes: Expanded polystyrene (EPS) foam containers
• Larger volumes: Rotational-molded insulated transport containers with insulated lids or thick quilted top pads

The thicker the insulation, the slower the rate of sublimation.

⚠️ Important Safety Warnings

• DO NOT store in airtight containers, sealed poly bags, or glass containers — sublimation will cause pressure buildup that can rupture or explode the container.
• DO NOT store in a freezer or refrigerator — it will cause the thermostat to shut off and can displace oxygen.
• ALWAYS store in a well-ventilated area — CO₂ gas is heavier than air and will sink to low areas, displacing breathable air.

Consult your dry ice or CO₂ gas supplier for more details and professional advice for your specific situation.
