In which hazard classification would you find poisonous solids?

Answer: B — Hazard Class 6

Poisonous solids are classified under Hazard Class 6, which specifically deals with toxic substances. This classification includes materials that can cause harm to human health or the environment through various routes of exposure, such as ingestion, inhalation, or skin contact. The primary focus of Class 6 is on the toxicity of the substances, which is why it encompasses both solid and liquid forms that are poisonous. Understanding the categories helps in recognizing the potential dangers associated with hazardous materials. For instance, Hazard Class 1 pertains to explosives, which is unrelated to poisonous solids, while Hazard Class 3 includes flammable liquids, focusing on fire-related hazards instead. Hazard Class 5 deals with oxidizers and organic peroxides, which also do not concern themselves with toxicity in the same way that Class 6 does. Thus, Class 6 is the appropriate classification for substances that are classified as poisonous solids.
