There are lead certification requirements for contractors who work on pre-1978 residential houses (build date of December 31, 1977 or earlier) or child-occupied facilities (kids under the age of 6 frequent on a regular basis - day cares, preschools, kindergartens, etc) that are in pre-1978 buildings. If your job is renovation, repair or painting on a pre-1978 house or child-occupied facility, then the Washington State RRP (Renovation, Repair, and Painting) training is required (for states that don't have their own RRP program you must be compliant with the Federal EPA RRP program). The WA State RRP Program is fully compliant with the EPA Program.
The purpose of the Renovation, Repair and Painting Program (RRP) is to minimize exposure from lead-based paint dust during renovation, repair, or painting activities. Common renovation activities like sanding, cutting, and interior demolition can create hazardous lead dust and chips by disturbing lead-based paint, which can be harmful to adults and children. Firms performing renovation, repair, and painting projects that disturb lead-based paint in pre-1978 homes or child care facilities in WA State must be certified by the WA State Department of Commerce and use certified renovators who are trained by an approved training provider to follow lead-safe work practices.
