In DOT hazard classifications, which class includes liquid poisons?

• A. Class 1
• B. Class 2
• C. Class 3
• D. Class 6

Answer: (D)

Toxicity is the factor that places a material in Class 6. Materials that can cause poisoning are categorized as toxic substances, which is Class 6, because the primary hazard they present is the potential to harm by exposure. This is true for liquids as well as solids, so a poisonous liquid is labeled as Class 6 rather than Class 3 (flammable liquids) or Class 2 (gases). Within Class 6, the main split is into 6.1 for toxic substances and 6.2 for infectious substances; liquid poisons fall under 6.1 unless they are infectious agents, which would be 6.2. In short, the reason liquid poisons belong to Class 6 is that their defining hazard is toxicity, not flammability or other properties.
