Which statement correctly describes a characteristic hazardous waste?

• A. It is a liquid waste that exhibits ignitability, corrosivity, reactivity, or toxicity
• B. It is a gas waste that exhibits ignitability, corrosivity, reactivity, or toxicity
• C. It is a solid waste that exhibits ignitability, corrosivity, reactivity, or toxicity
• D. It is any waste that has a hazard label

Answer: (C)

The key idea is how hazardous waste is identified by its characteristics: ignitability, corrosivity, reactivity, and toxicity. The regulatory framework defines a characteristic hazardous waste as one that exhibits one of these properties, and this identification is described in terms of a solid waste. So a solid material that shows any of these four traits is considered characteristic hazardous waste. This focus on solids comes from how the tests and controls are applied to solid waste streams at generation and disposal, ensuring consistent treatment of hazardous properties. While a liquid or a gas can also be hazardous, the standard description for a characteristic hazardous waste centers on solid waste exhibiting those properties. A waste labeled for hazard doesn’t automatically make it a characteristic hazardous waste, and a hazard label alone doesn’t define the four-property criteria.
