Dry Ice Special Instructions Dry ice is not a regulated waste, but it should not be disposed of in any waste bin, sink, toilet, or sewer. Safely dispose of unused dry ice by placing it into an uncovered, durable plastic or metal container, and allow it to sublimate in a well-ventilated area. Remember to wear appropriate hand protection when handling dry ice. Regulated in Transport The use of dry ice in transportation is regulated. Work with Transportation Services when intending to ship an item with dry ice.
