Remember, a closed car is an unventilated area, especially if the air is not on. Don’t leave dry ice in a parked, closed car. When transporting it, open the windows, or make sure you set the air conditioner to bring in fresh air. In addition, place it away from you when you’re driving. [8] X Research source
Don’t put dry ice down a sink or in a toilet, as you may destroy them. Similarly, don’t put dry ice in a trash can or leave it where it can accidentally be picked up or touched by someone who doesn’t know it’s dry ice, as it can burn them.
