WebContact Hazard: At -109 °F (-79 °C), skin contact with Dry Ice can lead to severe frostbite; skin cells freeze and become damaged very quickly. Asphyxiation Hazard: Dry Ice will sublime (change from solid to gas) at any temperature above -109 °F. This releases potentially substantial volumes of CO 2 (1 pound solid = 250 liters gas) causing ... WebAlthough not a cryogen, solid carbon dioxide or dry ice which converts directly to carbon dioxide gas at -78°C (-109°F) is also often used in laboratories. Cryogens, as well as dry …
WebCryogens can freeze flesh, causing painful blisters, much like a burn. Prolonged exposure can cause frostbite with pain occuring only when the flesh thaws. Flesh can stick to cold metals. Asphyxiation Cryogens expand into large volumes of gas that can displace air.
