Which DOT hazard class corresponds to poison or toxic materials?

• A. Class 3: Flammable liquids
• B. Class 7: Radioactive
• C. Class 6: Poison or toxic
• D. Class 9: Miscellaneous

Answer: (C)

Health hazard is the driving concern with poison or toxic materials. In DOT labeling, that translates to Class 6, which covers toxic substances (Class 6.1) that can cause poisoning through ingestion, inhalation, or absorption, and also includes infectious substances (Class 6.2) that can cause disease. The other classes represent different primary hazards: Class 3 is for flammable liquids, Class 7 is for radioactive materials, and Class 9 covers miscellaneous dangerous goods. So the classification that corresponds to poison or toxic materials is Class 6.
