Information on a hazardous materials table includes descriptions and shipping names, hazard categories, material identification numbers, packaging information and details about shipping methods, explains the Legal Information Institute. A hazardous materials table contains 10 primary columns, and divides three of these into subcategories.
The second column on a hazardous materials table designates proper shipping names and appropriate terminology for the transport of hazardous materials, states the Legal Information Institute. For instance, domestic shippers may use "toxic" and "poisonous" synonymously, but "inflammable" cannot replace "flammable." The third column designates a hazard class and specifies materials disallowed for transport. Forbidden materials that are stabilized, diluted or part of a device may be exempt from this designation.
Column four shows the identification number attached to each material. An identification number preceded by "UN" allows international shipping, while those preceded by "NA" are appropriate only for movement between the United States and Canada, according to the Legal Information Institute. Columns five and six assign packing group and labeling information to each material, which communicates the hazard level associated with the material. Columns 9A and 9B specify restrictions on the amounts of materials that may be shipped by rail or aircraft. Columns 10A and 10B outline how and where ships stow hazardous materials.
