What is meant by "bulk transport" of hazardous materials?

The term "bulk transport" of hazardous materials specifically refers to the movement of large quantities of these materials without packaging, meaning they are transported in large tanks or containers. This method is typically employed for substances that can be easily transferred and managed in significant volumes, such as liquids, gases, or loose solids that do not require individual packaging for safety during transport.

In contrast, transporting small, packaged quantities pertains to materials that are carefully divided into units that can be handled individually, which is not characteristic of bulk transport. Furthermore, while the use of bulk containers is common in bulk transport, it is not exclusive to this method, as bulk transport may involve various means without strict adherence to specific container types. Lastly, the idea of using road trailers for all hazardous materials does not accurately define bulk transport, as it encompasses a broader range of transportation methods and is not limited to trucks or trailers.
