Test painted surfaces for lead. You can rely on positive results from chemical lead-test kits, but if you get a negative result, collect and send samples to a lab for testing or have a professional test using an X-ray fluorescence machine.
Inform yourself! Start by reading "Protect Your Family From Lead in Your Home" and "Reducing Lead Hazards When Remodeling Your Home." Call the National Lead Information Service at (800) 424-5323 or download these brochures at www.epa.gov/lead.
Turn off air-conditioning and forced-air heating systems.
Move everything you can out of the work area. Cover and seal in plastic anything you can't move. For example, move furnishings out of a room and cover the floor with plastic.
Seal the work area with plastic and duct tape.
Take steps to control dust, such as misting work surfaces with water.
To clean, you will need a vacuum cleaner with a High Efficiency Particulate Air (HEPA) filter, buckets, disposal bags and more. Test for lead again after completing a major project.
Keep away everyone who does not need to be in the work area, especially children and pregnant women, who are more vulnerable to lead contamination.
Wear personal protection gear, including, for example, a respirator with HEPA filters that's approved by NIOSH (National Institute for Occupational Safety and Health), protective clothing and goggles.
