What is the primary hazard associated with DOT 412/312 tankers?

• A. Chemical burns
• B. Thermal burns
• C. Electrical hazards
• D. Radiation release

Answer: (D)

The main danger with DOT 412/312 tankers is the potential release of radioactive material and the accompanying ionizing radiation. When these tankers carry radiological cargo, a breach or improper handling can allow radiation to escape and contaminate people and the environment. That radiological risk drives the response: establish a controlled area, use radiation monitoring, decontaminate as needed, and summon specialized radiological responders. Other hazards—like chemical burns from corrosives, thermal burns from hot liquids, or electrical hazards—are concerns in other contexts, but they are not the primary threat associated with these tankers when the cargo involves radioactive materials.
