CDL Hazardous Materials Practice Test

The correct order for shipping descriptions follows specific guidelines established for transporting hazardous materials. This structure is designed to ensure clarity and consistency in identifying and labeling dangerous substances during shipment.

In the correct sequence, the name of the material is provided first, followed by its designation as a hazardous material (such as "Poison A"), and finally the UN (United Nations) number, which is a unique identifier assigned to hazardous substances and articles. This order is essential for safety and regulatory compliance, facilitating quick recognition and understanding of the substance being handled.

For the given choices, "Phosgene, Poison A, UN1076" adheres to this established format, presenting the substance first, categorizing it properly, and concluding with the UN number. This arrangement helps transporters, emergency responders, and regulatory authorities to process the information efficiently and respond appropriately in case of an incident.
