Hazardous Materials Class 7 deals with which material type?

• A. Corrosive
• B. Poison
• C. Radioactive
• D. Gases

Answer: (C)

Hazardous materials are grouped by the type of hazard they pose during transport. Class 7 is the category for radioactive materials, because radiation from these substances requires special controls to protect people and the environment. Shipping radioactive material involves specific packaging (often Type A or Type B packages), labeling with the radiation symbol, and regulatory restrictions on handling, storage, and routing. In aviation, these shipments must meet strict containment, licensing, and operational procedures to prevent exposure or contamination. Other hazardous materials belong to different classes with their own rules—corrosives, toxic substances, and gases are handled under separate classifications and requirements.
