A construction site item that may be considered hazardous waste is which of the following?

• A. Cleaning supplies.
• B. Plywood.
• C. Nails.
• D. Concrete.

Answer: (A)

Hazardous waste on a construction site often comes from chemicals in cleaners and solvents. Cleaning supplies can contain flammable solvents, corrosive or reactive ingredients, or other hazardous components, so when they’re used up, spilled, or simply disposed of, they may be classified as hazardous waste and require special disposal and handling. The other items—plywood, nails, and concrete—are typically inert or nonhazardous in normal use on a job site. Plywood is wood, nails are metal, and concrete is a concrete mixture; none pose the same potential for hazardous waste classification under standard conditions.
