Safe Handling, Transport & Use of Dry Ice
Dry ice is the solid form of carbon dioxide (CO2). Dry ice is extremely cold (−109.3 °F / −78.5 °C) and rapidly sublimates, or converts, into carbon dioxide gas at room temperature. It is used extensively as a cooling agent in a variety of applications such as food chilling and freezing, vaccine cooling, expendable refrigeration, blood and tissue sample preservation, heat treating of metals, and many more.
Anyone who handles dry ice should be aware of its unique properties and potential hazards. These include the extremely cold temperature, potential to create an oxygen-deficient atmosphere, and rapid conversion from a solid to gas. It is critical that users read and follow the instructions and safety precautions provided by their dry ice supplier.
This safety poster, provided by the Compressed Gas Association, provides basic safety information for the handling, transport, and use of dry ice. To learn more, see the section, “Product Information: Carbon Dioxide” at the bottom of this page.
Dry Ice Safety Reminders
Handling Dry Ice
- Use protective gloves or tongs
- NEVER handle with bare hands or place in mouth
Storing Dry Ice
- Store in cool, well ventilated areas
- Ventilation systems should exhaust from lowest level and make up from higher point
- Install carbon dioxide monitors
- Check carbon dioxide concentration before entering storage area
- NEVER store in airtight containers
Transporting Dry Ice
- NEVER transport in airtight containers
- Open windows or ensure constant supply of fresh air in vehicles

Product Information: Carbon Dioxide
Carbon dioxide gas/vapor is colorless, odorless, and about 1.5 times as heavy as air, while dry ice is white/opaque. Carbon dioxide can exist simultaneously at its triple point as a solid, liquid, and gas at a temperature of –69.9 °F (–56.6 °C) and a pressure of 60.4 psig (416 kPa). At temperatures and pressures below the triple point, carbon dioxide can be either a solid (dry ice) or a gas, depending upon temperature conditions. At temperatures and pressures above the triple point and below 87.9 °F (31.1 °C), carbon dioxide liquid and gas can exist in equilibrium in a closed container.
