Lead-based paint

The federal government banned lead-based paint for homes, childcare facilities and preschools in 1978. EPA says roughly three-quarters of US homes built before 1978 still contain some.

Intact paint is a smaller risk. EPA says children can live safely in these homes as long as paint and surfaces are in good condition and kept clean. The danger comes from chipping, peeling and dust, especially on doors, windows and sills where surfaces rub.

Renovation is the big trigger. Sanding, scraping or demolition can turn old paint into fine lead dust that settles on floors and toys. See the RRP rule for the work-practice law that applies to paid renovators.

Before you remodel an older building, test the paint. An XRF analyzer can read lead without damaging the surface. If hazards are found, lead abatement is the licensed route to remove or control them.
