Division 6.1 refers to which category of substances?

• A. Substances that are not toxic
• B. Toxic Substances that are liable to cause harm through ingestion, inhalation, or skin contact
• C. Radioactive materials
• D. Agricultural seeds

Answer: (B)

Division 6.1 designates toxic substances—chemicals that may cause harm if they are ingested, inhaled, or absorbed through the skin. This classification is used to cue specific handling, packaging, labeling, and documentation requirements because the risk comes from exposure to people. The other options don’t fit: radioactive materials belong to a different category (Class 7), agricultural seeds are not defined as toxic substances under this division, and there isn’t a general “not toxic” division in this system. So Division 6.1 is the category for substances that are toxic through ingestion, inhalation, or skin contact.
