Which class in the UN classification system refers to poisons?

The correct classification for poisons in the United Nations (UN) system is Class 6. This class is specifically designated for toxic substances and infectious substances. Within Class 6, there are further subdivisions, with Class 6.1 focusing on toxic substances that can cause harm through exposure or ingestion. This designation is important for regulatory and safety purposes, especially for transportation of hazardous materials, as it ensures that appropriate measures are taken to manage the handling and risk associated with these substances.

Other classes in the UN classification system cover different types of dangerous goods. For example, Class 4 includes flammable solids, Class 7 is designated for radioactive materials, and Class 8 pertains to corrosive substances. Each class has specific guidelines and regulations to ensure safety during the transportation and management of hazardous materials. Understanding these classifications is crucial for anyone involved in fire safety, hazardous materials handling, or regulatory compliance.
