HAZMAT CDL Practice Test

Which hazard class would you associate with radioactive materials?

1. Class 4

2. Class 6

3. Class 7

4. Class 8

The correct answer is: Class 7

Radioactive materials are categorized under Class 7 of the Hazardous Materials Identification System. This classification specifically addresses materials that emit ionizing radiation, which can pose significant health risks to individuals and the environment. Class 7 includes not only the radioactive substances themselves but also the items that are contaminated by them. The regulation and transportation of these materials are governed by strict guidelines to prevent exposure and ensure safety. These regulations are crucial because exposure to radioactive materials can result in serious health issues, including radiation sickness and increased cancer risk. This classification and the associated regulations are vital for maintaining safety during transportation and handling practices, as they provide essential information for drivers, emergency responders, and those working in facilities that handle such materials.
