Lead dust is easily inhaled or ingested and very difficult to identify. It may be scattered through the home, increasing the number of potential exposure sources. If surfaces that contain lead-based paint are in good condition, they do not pose a hazard and should be left alone. But any surface that shows signs of deterioration can easily release lead into the environment. Chipping and flaking Abrasions Water damage Recent demolition or construction Lead painted surfaces in and around the home include interior and exterior walls, ceilings, stairway components, door trim, and baseboards.
Window frames painted with lead-based paint can be a significant exposure risk.
Friction from opening and closing these windows can easily release lead dust that can collect on windowsills and other nearby surfaces. Any home renovation that disturbs lead painted surfaces can release very dangerous amounts of lead dust into the environment. Home renovations are a frequent cause of lead poisoning in children. Renovations should proceed only when those performing the work are well aware of the hazards and knowledgeable about procedures used to reduce the risk. Some states require contractors who remove lead paint to be licensed.
