What type of material at a construction site may be considered hazardous waste?

• A. Cleaning supplies.
• B. Water.
• C. Sand.
• D. Wood scraps.

Answer: (A)

Cleaning supplies can be hazardous waste at a construction site because many cleaning products contain hazardous chemicals such as solvents, acids, bases, or other toxic constituents. When these products are used up or become residues, they may exhibit characteristics like toxicity, ignitability, corrosivity, or reactivity, which classifies them as hazardous waste under regulatory rules. Water, sand, and wood scraps are typically non-hazardous unless they’ve become contaminated with hazardous substances. So cleaning supplies are the material most likely to be considered hazardous waste.
