Which class includes radioactive materials?

Class 7 specifically pertains to radioactive materials as defined by the United Nations' transport classifications for hazardous materials. This classification encompasses any material that emits ionizing radiation and includes both fissile and non-fissile materials, which can pose risks to health and safety if not handled appropriately.

Understanding the significance of Class 7 is crucial for first responders and hazardous materials teams. It informs them about the potential health hazards associated with exposure to radioactivity and guides them in planning appropriate handling, transportation, and containment procedures to mitigate those hazards.

In contrast, other classes focus on different types of hazards. Class 5 pertains to oxidizers and organic peroxides, which increase the risk of fire and explosion. Class 6 is associated with toxic and infectious substances, which pose health risks primarily through exposure. Class 8 includes corrosive substances, which can damage living tissue and materials. Each classification is critical in managing the unique risks they present, but Class 7 is specifically designated for the challenges posed by radioactive materials.
