Handling dry ice requires caveat, as its extremum temperature can lead to serious injuries if proper refuge quantity are not followed. A dry ice burn is fundamentally a form of cryopathy, occurring when skin arrive into direct contact with the solid shape of carbon dioxide, which sits at an astonishing -109.3°F (-78.5°C).
