HUD defines a lead-based paint hazard as lead present at or above which thresholds?

HUD defines a lead-based paint hazard using two criteria that can trigger hazard status: if on friction or impact surfaces the paint contains 1.0 mg of lead per square centimeter, or if the paint itself contains lead at or above 0.5% by weight (about 5000 ppm). So, a surface like a window sill that wears and could create lead dust is hazardous at 1.0 mg/cm2, and any accessible painted surface with 0.5% lead by weight is hazardous regardless of wear. This is why the correct threshold pair is 1.0 mg/cm2 or 0.5% by weight. The other numerical options do not match HUD’s defined thresholds.
