CDL Hazardous Materials Practice Test

Which of the following shipping paper descriptions for a hazardous material is in the correct order?

1. Hydrogen bromide, UN 1048, non flammable gas

2. Hydrogen bromide, non flammable gas, UN 1048

3. 1048, Hydrogen bromide, non flammable gas

4. Non flammable gas, Hydrogen bromide, UN 1048

The correct answer is: Hydrogen bromide, non flammable gas, UN 1048

The correct choice follows the required order for shipping paper descriptions of hazardous materials as established by regulations. The correct format begins with the proper shipping name, followed by the UN identification number, and then the hazard class or description. In this case, "Hydrogen bromide" is the proper shipping name, "UN 1048" is the UN identification number, and "non flammable gas" indicates the hazard classification. This order ensures that anyone handling the shipment can quickly identify both the material and its associated hazards, which is crucial for safety and regulatory compliance. The other options do not adhere to this structure; they either place the UN number or the hazard classification in the wrong sequence or use an incorrect format, which could lead to confusion or improper handling of the hazardous material in transit. Proper compliance with this order is essential to ensure that emergency responders can easily understand the contents of the shipment in case of an incident.
