Sources of Lead
Lead paint is still present in millions of older structures, sometimes under layers of newer paint.
Lead dust is common in windows, doors, and soil.
If the paint is in good shape, the lead paint is usually not a problem. Deteriorating lead-based paint (peeling, chipping, chalking, cracking, damaged, or damp) is a hazard and needs immediate attention.
In 1978, the federal government banned consumer uses of lead-containing paint. The older the structure, the more likely lead is present.
Sources of Contamination
- Windows and window sills;
- Doors and door frames;
- Stairs, railings, banisters, and porches.
- Lead in household dust results from indoor sources such as deteriorating lead-based paint.
- Lead dust can also be tracked into a structure from soil outside that is contaminated by deteriorated exterior lead-based paint and other lead sources, such as industrial pollution and past use of leaded gasoline.
- Renovation, repair or painting activities can create toxic lead dust when painted surfaces are disturbed or demolished. Learn more about hiring lead-safe certified contractors.
- Pipes and solder - Lead is used in some water service lines and household plumbing materials. Lead can leach, or enter the water, as water flows through the plumbing. Lead pipes and lead solder were commonly used until 1986.
- Flame-torch cutting, welding, the use of heat guns, sanding, scraping and grinding of lead painted surfaces in repair, reconstruction, dismantling and demolition work;
- Abrasive blasting of bridges and other structures containing lead-based paints;
- Use of torches and heat guns, and sanding, scraping and grinding lead-based paint surfaces during remodeling or abating lead-based paint; and
- Maintaining process equipment or exhaust duct work.
