Which of the following is listed as an example of Class 9 substances?

• A. Lithium batteries
• B. Water
• C. Glass
• D. Cotton fabrics

Answer: (A)

Class 9 covers miscellaneous dangerous goods—items that don’t fit neatly into the other eight classes but still pose hazards in transport. Lithium batteries fit here because they contain a concentrated energy source that can short-circuit, overheat, or ignite if damaged, improperly packed, or subjected to rough handling. That fire and thermal risk is why they’re listed as Class 9 and require specific packaging, labeling, and handling rules to prevent incidents during shipment. Water, glass, and cotton fabrics aren’t classified as Class 9 substances in typical regulations; they aren’t considered the hazardous items that need the extra precautions applied to Class 9 materials.
