When handled properly, dry ice is safe and easy to use. Please make sure that all users read and understand the information below.
Dry ice is solidifies carbon dioxide (CO2). Distinct from regular ice, which exists at temperatures of 320F (0oC) and below, dry ice is extremely cold, -109oF (-79oC). And unlike water ice, dry ice does not melt. Instead, it sublimates (goes directly from a solid to a gas), releasing CO2 vapor. CO2 vapor is substantially heavier than air. In confined, poorly ventilated spaces, it can displace air, causing asphyxiation. It is even possible for CO2 vapor to accumulate in low-lying areas out-of-doors under zero or very light wind conditions.
