In the Hazardous Materials Table, proper shipping names are set in regular (Roman) type, and any wording in italics is not part of a proper shipping name. Shipping papers must use the proper shipping name itself, so an italicized name cannot take its place.
Along with the Hazardous Materials Table, shippers, carriers, and drivers check this list, which names hazardous substances and the reportable quantity for each, to see whether a material is regulated. Indexes of restricted freight or tables of load sizes are not official sources for this.
An 'I' identifies the proper shipping name to use when materials move internationally; if only domestic transportation is involved, a different name may be used. It is the counterpart of the 'D' symbol, which marks names appropriate for domestic shipments.
Column 1 symbols explain how an entry applies to different kinds of transportation. A 'D' signals that the proper shipping name is appropriate for domestic transportation but may not be correct for international shipments; generic names are marked 'G', and water-only coverage is marked 'W'.
Appendix B, the List of Marine Pollutants, covers chemicals that are toxic to marine life, but for road shipments it is used only when the container can hold 119 gallons or more. The 1,001-pound figure comes from the placarding rules, not from the marine pollutant list.
Appendix B is the List of Marine Pollutants, which covers chemicals that are toxic to marine life and singles out the severe ones. Appendix A instead lists hazardous substances with their reportable quantities.
This federal DOT list names every material regulated as hazardous in shipping and spreads each entry's details across ten numbered columns, from the symbols in Column 1 to Columns 9 and 10, which cover air and vessel shipments.
A technical name is the accepted chemical or microbiological name found in scientific handbooks, journals, and texts. Slang terms and brand or trade names do not qualify.
Shipping papers describe a hazmat entry with its ID number, proper shipping name, hazard class or division, and packing group. Words in italics in the table are not part of the proper shipping name, so they are not part of the basic description either.
Column 2 lists each material's description and proper shipping name. The hazard class or division appears in column 3, and the identification number in column 4.
Only the names printed in Roman type in the table are proper shipping names; words in italics are not, so they cannot serve as one. The identification number is a normal part of hazardous materials markings.
The symbol 'A' limits the Hazardous Materials Regulations to air transportation of that material, unless it is also a hazardous substance or a hazardous waste. The symbol that points to transportation by water is 'W'.
Column 4 lists each material's identification number, which is the four-digit number after the letters UN or NA. The number is required on shipping papers, packages, cargo tanks and other bulk containers; Column 3, in contrast, shows the hazard class or division.
When "Forbidden" appears where the hazard class should be, the material cannot be offered for shipment or transported, so a carrier must refuse it regardless of the packaging or the amount.
Symbols in Column 1 qualify an entry. The letter "A" means the HMR apply to the material only when it moves by air, except when it is also a hazardous substance or a hazardous waste. A "D" marks a name meant for domestic shipments, and a plus sign fixes the name, class, and packing group.
