Hazard Class 7 is associated with which type of material?

Hazard Class 7 is associated with which type of material?

• A. Corrosives
• B. Gases
• C. Flammable liquids
• D. Radioactive

Answer: (D)

Understanding how hazardous materials are categorized for transport, Class 7 denotes radioactive materials. This class covers materials that emit ionizing radiation and require special handling, shielding, and regulatory controls. Examples include medical isotopes, sealed radioactive sources used in industry, and certain nuclear fuel materials. These are distinct from other hazard classes: corrosives are designated as a different class that deals with materials capable of causing severe chemical burns and material damage; gases are classified separately as Class 2, covering compressed, liquified, or dissolved gases; flammable liquids belong to Class 3, which includes liquids with a low flash point that can ignite easily. Because the question asks which type of material aligns with Class 7, radioactive materials is the correct association.
