In the material, a lead-based paint hazard is defined as equal to or greater than how many milligrams per square centimeter?

• A. 0.2 mg/cm2
• B. 2 mg/cm2
• C. 20 mg/cm2
• D. 200 mg/cm2

Answer: (B)

The key idea is how a lead hazard is defined in paint by the amount of lead per surface area. In this material, a paint hazard is identified when the lead loading on a painted surface is equal to or greater than 2 milligrams per square centimeter. This threshold means that if you measure the paint and find 2 mg of lead or more on each square centimeter of the surface, it’s considered a lead-based paint hazard and typically triggers remediation actions. The other numbers (0.2, 20, or 200 mg/cm2) don’t match this defined threshold—they would indicate levels that are either well below or well above the standard hazard level.
