hazardous material
Requires special handling
Hazardous material is any substance that poses a risk to health, safety, or property—chemicals, radioactive materials, flammable liquids, explosives, or biological agents.
The term appears in regulatory and industrial contexts: The truck was placarded for hazardous materials.
Often shortened to hazmat: a hazmat suit, hazmat team.
