Temperature And Choosing A Solids Or Liquids Drum

If a hazardous material, at ambient temperatures, meets the definition of a solid under CFR 171.8 when packaged and offered for transportation, it is a solid material. However, if the solid will likely encounter temperatures in transportation that may cause the material to become a liquid per CFR 173.197(e)(5), then the packaging must be capable of containing the hazardous material in the liquid state. Most of Skolnik‘s UN Certified drums are tested and marked for both Liquids and Solids — thus one drum from both states. A Solids drum is tested with a solids (sand) content. A Liquids drum is tested with water. Solids drums can only be open heads whereas Liquids drums can be either open or closed head.
