Which of the following does not belong to the category of dangerous goods?

• A. Explosives
• B. Toxic substances
• C. Biohazard substances
• D. Radioactive substances

Answer: (C)

Dangerous goods are grouped into official classes used in transport regulations. Explosives and radioactive substances are clear, distinct classes, and toxic substances fall under a recognized category as well. A term like biohazard, while common in safety discussions, isn’t an official separate class in the dangerous goods framework. In transport rules, infectious substances (a type of biological hazard) are included with toxic and infectious substances in the same Class 6 category, not as a standalone “biohazard” class. So labeling something as a biohazard substance doesn’t match an official danger goods category by itself; it would be treated as an infectious or toxic substance under the existing class structure. That’s why the option describing biohazard substances doesn’t belong as its own dangerous goods category, while the other options align with defined classes: explosives as a separate class and radioactive substances as another, with infectious substances falling under the appropriate part of Class 6. When shipping biological materials, you’d identify them as infectious substances under Class 6 and follow the corresponding packaging, labeling, and documentation requirements.
