A dangerous good is any solid, liquid, or gas that can harm people, other living organisms, property, or the environment. An equivalent term, used almost exclusively in the United States, is hazardous material (HAZMAT). Dangerous goods may be radioactive, flammable, explosive, toxic, poisonous, corrosive, biohazardous, an oxidizer, an asphyxiant, a pathogen, an allergen, or may have other characteristics that render it hazardous in specific circumstances.
