 When using compressed carbon dioxide or dry ice, care should be taken to ensure there is sufficient ventilation available at all times, and that procedures are in place to rapidly evacuate CO2 from any enclosed space in an emergency.Liquid carbon dioxide (−56.6 °C) and dry ice (−78.5 °C) present a significant risk of frostbite if mishandled.Proper protective clothing, such as long sleeves and gloves, should always be worn when handling these products.
