This handbook summarizes requirements of EPAâs Lead-Based Paint Renovation, Repair and Painting. Program Rule, aimed at protecting against lead-based paint hazards associated with renovation, repair and. painting activities. The rule requires workers to be trained to use lead-safe work practices and requires renoÂ­. vation irms to be EPA-certiied; these requirements will become effective April 22, 2010.
The U.S. government defines lead-based paint as any paint, surface coating that contains lead equal to or exceeding one milligram per square centimeter (1.0 mg/cm2) or 0.5% by weight.. Some states have adopted this or similar definitions of lead-based paint.. These definitions are used to enforce regulations that apply to certain activities conducted in housing constructed prior to 1978, such as abatement, or the permanent elimination of a lead-based paint hazard..
