Lead-based paint is usually not a hazard if it is in good condition, and the paint is not on an impact or friction surface, such as a window. Deteriorating lead-based paint (peeling, chipping, chalking, cracking, or damaged paint) is a hazard and needs attention. Lead dust can form when lead-based paint is scraped, sanded, or heated. Dust also forms when painted surfaces bump or rub together. Lead chips and dust can reside on surfaces and objects that people touch.
