Class 9 hazardous materials are designated for which category?

Class 9 hazardous materials are designated for which category?

• A. Class 3: Flammable liquids
• B. Class 2: Gases
• C. Class 9: Miscellaneous hazardous materials/dangerous goods
• D. Class 4: Flammable solids

Answer: (C)

In hazmat classification, materials are grouped by the type of hazard they present, and Class 9 is the miscellaneous dangerous goods category. This catch‑all is used for items that are hazardous but don’t fit into the other eight classes. It covers a variety of unusual or mixed hazards, such as lithium batteries and environmentally hazardous substances, that still require special handling and transport rules. The other choices refer to specific hazards: flammable liquids belong to Class 3, gases to Class 2, and flammable solids to Class 4. Therefore, Class 9 is the correct designation for miscellaneous dangerous goods.
