The correct order of shipping paper descriptions for hazardous materials follows a specific format as outlined in the Department of Transportation (DOT) regulations. This format typically includes the proper shipping name, hazard class, and UN number in a logical sequence, ensuring clarity and safety during the transportation of hazardous materials.

In the case of the selected answer, hydrogen bromine is correctly identified as a non-flammable gas and is followed by its assigned UN number (UN 1048). This follows the format that first identifies the material and its state before categorizing its hazard classification and providing the UN number, which serves as a unique identifier for that particular substance.

The other options do not adhere to the universally accepted format for hazardous material descriptions. In particular, descriptions may contain inaccuracies in naming conventions, classifications, or incorrectly structured sequences that could lead to misunderstandings when handling hazardous materials. Proper understanding and implementation of these descriptors are crucial for safety and compliance in transporting hazardous materials.
