What information is typically included in the markings on the outer packaging of hazardous materials?

• A. Descriptive name, UN number, weight, and cautions
• B. Color of container
• C. Packaging date only
• D. Manufacturer address only

Answer: (A)

The markings on outer packaging are meant to quickly tell you what the material is, where it fits in the regulations, how much is inside, and what special precautions you should take. The typical markings include a descriptive name of the substance, the UN number, the weight or quantity, and cautions or hazard statements. The descriptive name identifies the material, the UN number provides a universal identifier that aligns with regulatory and emergency response guides, the weight or quantity informs handling and shipping requirements, and the cautions convey the specific hazards and any necessary safety measures. Color of the container, packaging date, or a manufacturer address alone don’t give this essential combination of identification, quantity, and safety information, so they aren’t the standard markings used for hazmat shipments.
