What is the key characteristic of Class 7 hazardous materials?

Class 7 hazardous materials are specifically characterized by their radioactive properties. This classification includes materials that emit radiation and pose risks associated with exposure to radiation, which can be harmful to human health and the environment.

In the realm of hazardous materials, each class is defined by its unique characteristics and dangers. While flammability, corrosiveness, and toxicity are important considerations for other classes of hazardous substances, they do not pertain to Class 7. This class is distinct due to its focus on the effects of radiation, which requires specialized handling, storage, and transportation protocols to ensure safety and compliance with regulations. Understanding the specific attributes of Class 7 helps in identifying the appropriate safety measures needed when dealing with such materials.
