Dry ice blasting also requires no additional time for drying. When compared with commonly used chemicals and solvents, dry ice blasting is a superior cleaning method. Unlike cleaning solutions, dry ice blasting is non-toxic and does not produce secondary waste. Overall, this makes it a safer and more environmentally-friendly cleaning option.
In addition, the CO2 used to make dry ice pellets is typically captured as a byproduct of other industrial activities and repurposed.

Part 3. Do not store dry ice in a completely airtight container. The sublimation of dry ice to carbon dioxide will cause the container to expand and possibly explode. Dry ice can cause a violent eruption if packed too tightly. Some people have been brought up on felony criminal charges for purposely confining dry ice until it explodes, creating a dry ice "bomb. Avoid keeping dry ice in cellars, basements, cars, or other poorly ventilated areas. The carbon dioxide from the dry ice will gradually begin to replace oxygen and can cause suffocation if breathed exclusively.
