Transportation of Dangerous Goods


Dangerous Goods are substances, mixtures, or articles that are considered dangerous (and thus regulated) for transportation. “Dangerous Goods (DG)” is the term most frequently used internationally. In the United States, the more common term is “Hazard Materials (HazMat)”.

Transportation regulations are typically based on the UN “Orange Book” – the UN Recommendations on the Transport of Dangerous Goods. Criteria exist for nine primary hazard classes:

  1. Explosives
  2. Gases
  3. Flammable Liquids (includes Combustible Liquids in North America)
  4. Flammable Solids, Spontaneously combustible, Dangerous when wet
  5. Oxidizing Agents and Organic Peroxides
  6. Toxic and Infections Substances
  7. Radioactive Substances
  8. Corrosive Substances
  9. Miscellaneous (materials that do not fit into other classes, such as asbestos, environmental hazards [marine pollutants], dry ice, etc.)
