After use, dry ice should be disposed of properly. It is important to never dispose of dry ice in a regular trash can as it can cause damage to the bin and may even lead to injury if touched without proper protection. Instead, place the remaining dry ice in an insulated container or bag and allow it to evaporate outdoors away from people and pets. Additionally, avoid contact with skin when handling dry ice, as extreme cold temperatures can cause frostbite or other injuries.
