What does Hazard Class 7 represent?

Hazard Class 7 represents radioactive materials. This classification is specifically designated for substances that emit ionizing radiation, which can be harmful to human health and the environment. Radioactive materials can include isotopes used in medical applications, industrial gauges, and certain research materials. The regulation of these materials under Hazard Class 7 ensures that they are handled, transported, and disposed of with stringent safety measures to mitigate risks associated with radiation exposure.

The other hazard classes mentioned do not pertain to radioactive materials. Cytotoxic materials, corrosive materials, and miscellaneous hazardous materials each have their own distinct classifications and safety protocols, indicating that this is a specialized category focusing exclusively on the unique hazards presented by radioactivity.
