Description
Carbon dioxide, solid (dry ice) is produced by expanding liquid carbon dioxide to vapour and “snow” in presses that compact the product into blocks. It is used primarily for cooling and due to its very low temperature (about -79°C), can cause severe burns to skin upon direct contact. When carbon dioxide, solid (dry ice) converts (sublimates) directly to gaseous carbon dioxide, it takes in heat from its surroundings. The resulting gas is heavier than air and can cause suffocation in confined areas as it displaces air. Packages containing carbon dioxide, solid (dry ice) must be designed and constructed so as to prevent build-up of pressure due to the release of carbon dioxide gas.
Upon successful completion of this training course, individuals will have an understanding of the rules and regulations governing the transport of dry ice, including documentation, packaging and marking and labelling requirements for shipping dry ice.
