What essential information must be included on shipping papers for hazardous materials?

The requirement for including specific information on shipping papers for hazardous materials is crucial for safety and compliance with regulations. The correct answer emphasizes the need for details that ensure the safe transport and handling of hazardous materials.

The proper shipping name identifies the specific material being transported, allowing first responders to understand what they're dealing with in case of an emergency. The hazard class categorizes the material based on its risk characteristics, which is essential for determining the precautions necessary during transport. The UN number is a unique identifier assigned to hazardous substances and facilitates quick identification during emergencies. Finally, having an emergency contact ensures that there is a responsible party available to provide information or guidance if an incident occurs.

Other options contain information that, while potentially useful in various shipping contexts, do not meet the specific safety and regulatory requirements for hazardous materials. Shipping cost, delivery date, and sender's address, for instance, do not contribute to emergency response preparedness. Similarly, product weight and expiration date may be relevant in different contexts but lack the specific details required to ensure safe handling of hazardous materials. Finally, handling instructions and a tracking number are not part of the mandatory details needed on shipping papers for hazardous materials.
