Toxic Substances are classified under which division?

• A. Division 6.1
• B. Division 5.2
• C. Division 4.2
• D. Division 6.2

Answer: (A)

Toxic substances are grouped by the hazard they pose: chemical toxicity. This places them in the division that specifically covers Toxic Substances, separate from other hazard categories like Infectious Substances, organic peroxides, or flammable solids. The key idea is that the risk comes from the chemical's ability to harm the body through inhalation, ingestion, or skin absorption, not from being a disease-causing organism. So handling, packaging, and labeling are tailored to chemical toxicity rather than biological risk. For contrast, infectious substances have a different division because their danger comes from causing disease, not chemical toxicity. Examples of toxic chemicals include cyanide or certain pesticides, which illustrates why they belong in the Toxic Substances division.
