Which statement best defines hazardous waste?

• A. A solid, liquid, or contained gas material that is no longer used or no longer serves its purpose and could pose dangers after discarded
• B. A non-toxic household item
• C. Water-based liquids only
• D. Any waste that is biodegradable

Answer: (A)

Hazardous waste is any material that, after its useful life, could pose a danger to people or the environment when it’s discarded. It can be a solid, a liquid, or a contained gas, and its danger comes from properties like toxicity, flammability, reactivity, or corrosiveness. In pesticide management, this includes leftovers of pesticides, containers with residue, rinsates, contaminated soil or equipment, and PPE that have pesticide contamination. So the statement that best defines hazardous waste is that a material no longer used can still pose dangers after it’s discarded. The other options fail because a non-toxic item isn’t hazardous, it’s not limited to only water-based liquids, and being biodegradable doesn’t inherently make something hazardous.
