Corrosives belong to which hazard class?

• A. Class 8
• B. Class 7
• C. Class 6
• D. Class 9

Answer: (A)

Corrosives are categorized under the hazard class whose defining danger is the ability to cause severe damage by chemical action to skin, eyes, and metals. This classification is Class 8. That’s because the primary risk they pose in transport and handling is corrosion, not flammability, radioactivity, toxicity, or other hazards. Examples like sulfuric acid or sodium hydroxide illustrate why they belong here—they can aggressively corrode materials and tissue. This classification guides the required packaging, labeling, and handling procedures. Other hazard classes cover different dangers—radioactive materials, toxic substances, or miscellaneous dangerous goods—so they don’t apply to corrosives.
