Describe Class 9 HAZMAT.

Describe Class 9 HAZMAT.

• A. Radioactive materials
• B. Infectious Substances
• C. Flammable liquids
• D. Miscellaneous hazards not covered by other classes (e.g., anesthetic gases)

Answer: (D)

Class 9 is the catch‑all category for dangerous goods—the miscellaneous hazards that don’t fit any of the other eight classes. That’s why the description fits best: it isn’t limited to a single, well-defined type like radioactive materials, infectious substances, or flammable liquids. Instead, it covers a range of materials that pose hazards in transport but aren’t covered by the other classes, such as certain batteries, dry ice, environmentally hazardous substances, or other unusual or mixed hazards that require special handling and labeling. The other options point to specific classes, while Class 9 exists precisely to label those items that don’t belong to any of the others.
