Which hazmat class is designated for radioactive material?

• A. Class Seven - Radioactive Material
• B. Class Five Oxidizing Substances and Organic Peroxides
• C. Class Three - Flammable Liquids
• D. Class Two - Gases

Answer: (A)

Radioactivity is handled under hazmat transport as Class 7. This category is set apart because the hazard comes from radiation exposure rather than chemical reactivity, so it requires specialized packaging, shielding, monitoring, and labeling, plus strict regulatory controls for safe transport. The other classes refer to different hazards: oxidizers and organic peroxides are Class 5, flammable liquids are Class 3, and gases are Class 2. Those do not involve radiation, so they are not the designation for radioactive material.
