Which hazard class includes liquid poisons, military agents, flammable solids, and poison gases?

Hazard Class 6 is correctly identified as the class that includes liquid poisons, military agents, flammable solids, and poison gases. This classification specifically encompasses toxic and infectious substances, which pose significant risks to human health and safety.

Liquid poisons and poison gases fall under the toxic substances category that is part of Hazard Class 6. These materials can cause serious harm through inhalation, ingestion, or skin contact. Military agents, which may include chemical warfare agents, are also classified here because of their highly toxic nature and potential for mass harm.

In contrast, the other hazard classes do not encompass the same range of toxic substances. Hazard Class 5 pertains to oxidizers and organic peroxides, Hazard Class 4 relates to flammable solids, and Hazard Class 3 involves flammable liquids. Each of these classes addresses different properties and hazards, highlighting the importance of proper identification and response strategies for each category. Understanding these classifications helps responders effectively plan and execute safety measures in the event of a hazardous materials incident.
