Which division is Infectious Substances?

Which division is Infectious Substances?

• A. Toxic Substances Division 6.1
• B. Infectious Substances Division 6.2
• C. Organic Peroxides Division 5.2
• D. Flammable Solids Division 4.2

Answer: (B)

In the transport classification, Class 6 covers Toxic Substances, and its divisions distinguish different hazards. Infectious Substances are assigned to Division 6.2 because they are biological hazards—materials known or reasonably expected to contain pathogens that can cause disease. This grouping sets them apart from Division 6.1, which covers toxic chemical substances based on chemical toxicity rather than the presence of pathogens. The other options point to entirely different classes or divisions (flammable solids, organic peroxides), which explains why Division 6.2 is the correct placement for Infectious Substances.
