In the UN classification system, what does Class 7 signify?

Class 7 in the UN classification system specifically designates radioactive materials. This classification is critical for the safe handling, storage, and transportation of substances that emit radiation, which can pose significant health risks to humans and the environment.

Radioactive materials require stringent safety protocols to prevent exposure and contamination, and their proper identification under the UN classification system helps ensure that responders are aware of the potential hazards associated with these materials. This classification is distinct from other classes, each of which covers different types of hazardous materials, such as oxidizers, flammable solids, and toxic substances. Therefore, understanding that Class 7 pertains to radioactive materials is essential for anyone involved in emergency response or hazardous materials management.
