Which option is a correct example of Hazard Class 9 Miscellaneous Dangerous Goods?

• A. Dry Ice
• B. Propane
• C. Hydrochloric Acid
• D. Sodium Chloride

Answer: (A)

Miscellaneous dangerous goods cover items that don’t fit neatly into the other hazard classes. Dry ice fits here because it’s solid carbon dioxide that sublimates to gas and can pose a asphyxiation risk in enclosed spaces, even though it isn’t flammable, corrosive, or toxic in liquid form. Its transport is governed by Class 9 rules for miscellaneous dangerous goods, separate from other classes. Propane is a flammable gas and falls under Class 2. Hydrochloric acid is a corrosive liquid and is Class 8. Sodium chloride is ordinary salt with no inherent transport hazard requiring Class 9 labeling. Therefore, dry ice is the correct example of Hazard Class 9 miscellaneous dangerous goods.
