Safe Handling, Transport, & Use of Dry Ice

Dry ice is the solid form of carbon dioxide (CO2). 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. It is also sometimes used to create special effects such as fog for events or stage presentations.

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 critical that users read and follow the instructions and safety precautions provided by their dry ice supplier.

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. This safety poster, provided by the Compressed Gas Association, provides basic safety information for the handling, transport, and use of dry ice.

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.
