  2. Monitoring and regulating hazardous shipments

  3. Providing discounts on shipping costs

  4. Offering loyalty programs for frequent shippers

The correct answer is: Monitoring and regulating hazardous shipments

The key function of the Postal Service regarding hazardous materials is to monitor and regulate hazardous shipments. This is essential because hazardous materials can pose safety risks not only to postal employees but also to the public and the environment. Therefore, the Postal Service has established guidelines and regulations that govern how these materials are handled, packaged, and transported to ensure safe delivery and compliance with federal laws. This includes adhering to regulations set forth by the Department of Transportation (DOT) and the Occupational Safety and Health Administration (OSHA), among others. By focusing on monitoring and regulating these shipments, the Postal Service maintains safety standards and promotes responsible shipping practices, which helps prevent accidents and incidents associated with hazardous materials.
