Carbon Dioxide (CO
) and Dry Ice Properties
2
At a temperature of -15°C (5°F) under normal atmospheric pressure, carbon dioxide has a density of 1.87 kg/m3 (0.12
lb/ft3) and is 1.5 times heavier than air. It is a colorless and odorless gas with a slightly pungent odor at higher
concentrations and spreads along the ground.
Carbon dioxide gas will collect in low-lying areas such as pits and cellars.

Dry Ice Production Process

The expansion of liquid carbon dioxide at pressures between 15-18 bar (217.6-261.1 psi) to atmospheric pressure is how
the pelletizers produce CO
density dry ice pellets.

Safety Hazards

Dry ice is extremely cold and may cause severe frost bite or tissue damage when in direct contact with exposed skin.
Always wear protective gloves and clothing when handling dry ice. CO
It is normally present in the atmospheric air at a level of approximately 0.04%. It is a normal product of metabolism being
