Dry ice is solidified carbon dioxide and is much colder than regular ice. It can burn skin similar to frostbite. As dry ice melts, it turns into carbon dioxide gas and can be a very serious hazard in a small space that isn't well-ventilated. You should wear thick, insulated gloves when handling it and avoid inhaling carbon dioxide gas.

Keep dry ice out of the reach of children and pets. Never eat or swallow dry ice. For safe disposal, allow leftover dry ice to melt and turn into gas in a well-ventilated area. Dry ice can cause carbon dioxide gas to accumulate and build up pressure. Do not dispose of dry ice in a sewer, garbage disposal, garbage chute, etc.
