Which of the following UN Hazard Classes is associated with toxic substances?

UN Hazard Class 6 is designated for toxic substances, which include materials that can cause harm or death upon exposure. This classification is crucial for handling, transporting, and responding to incidents involving such materials, as it informs first responders and emergency personnel about the potential risks and necessary precautions.

Class 6 is further divided into two divisions: Division 6.1 for toxic substances that are harmful or lethal, and Division 6.2 for infectious substances. Recognizing the characteristics and behaviors of these substances is vital in emergency situations to ensure the safety of responders and the public.

In contrast, the other hazard classes each pertain to different types of materials. For instance, Class 7 is related to radioactive materials, Class 8 includes corrosive substances, and Class 9 covers miscellaneous hazardous materials that do not fit into the other defined classes. Understanding these distinctions helps ensure that appropriate response measures are taken during emergencies involving hazardous materials.
