Yes, if not properly handled, it may be hazardous. Dry ice is just carbon dioxide. At low altitudes, carbon dioxide-produced gases displace oxygenated air. If there is insufficient ventilation, carbon dioxide can cause suffocation and death. Oven mitts may also be useful while working with dry ice. However, it is best to avoid direct skin contact and prolonged exposure. In general, keep children away from dry ice. It is incredibly cold, and if it comes into touch with your skin, it can immediately cause frostbite. As a result, it is also essential to properly dispose of dry ice after use. It may also endanger wildlife and pets while ruining diverse surfaces.
