What are the toxic levels of dry ice?

Dry ice, which is the solid form of carbon dioxide, is not dangerous if it is stored and used correctly. It can present hazards because it is extremely cold and quickly sublimates into carbon dioxide gas. While carbon dioxide is not toxic, it can build pressure or displace normal air, potentially causing problems. read more
