What does UN1845 correspond to?

UN1845 corresponds to Dry Ice, which is the solid form of carbon dioxide (CO2). It is used primarily as a refrigerant because it sublimates at temperatures below -78.5 degrees Celsius. In the context of transporting dangerous goods, Dry Ice is categorized under the UN number 1845 due to its nature of being non-flammable but having asphyxiating properties when it sublimates in confined spaces. It must be handled with care to ensure that it does not create a hazardous atmosphere.

The classification of Dry Ice as a dangerous good highlights the importance of awareness when shipping or handling materials that can pose risks when not properly managed. Dry Ice can release gas that may displace oxygen in enclosed areas, which is why it requires specific packaging and labeling in transport situations.

Understanding UN classifications such as UN1845 is crucial for individuals involved in the handling, shipping, or transportation of hazardous materials, enabling them to take the appropriate safety measures to protect themselves and others.
