Which hazard class includes toxic materials like cyanides?

Explanation:
Toxic materials are designated as Hazard Class 6.1 because their primary hazard is poisoning to humans. Cyanides are among the most toxic substances, with exposure that can cause severe harm or death through inhalation, ingestion, or skin absorption. That level of toxicity places cyanides squarely in the toxic substances category, Class 6.1. The other classes describe different hazards—Class 2 covers gases, Class 3 covers flammable liquids, and Class 8 covers corrosives—so cyanides aren’t classified by those hazards.
