Repainting Lead-Based Paint
In April 2011 the EPA will finally put its long standing rules about lead paint abatement into effect. Back in 1991 new rules were established for dealing with renovations on homes built before 1978. These rules were intended to stop lead poisoning in children due to disturbing painted surfaces containing lead-based paint from such activities as scraping and sanding for repainting as well as remodeling and demo work that involves disturbing lead coated surfaces and releasing lead dust into the air.
What the Rules State
Anyone being paid to do renovations or painting, such as a home improvement contractor, is required to be trained and certified in methods of containing and cleaning up the lead dust involved in their activities.
EPA approved methods for dealing with renovations call for covering surfaces, including floors and other places lead dust could settle, with plastic sheeting. In addition the plastic must extend beyond the work area by six feet in all directions. In addition, a misting of water is required while working to keep dust down.
No demo may be done that would spread debris such as breaking wall materials, etc. with a hammer, instead these surfaces must be gently broken apart in other ways. All power tools that cut, sand or grind must be hooked up to a vacuum system with a HEPA filter and heat guns may not exceed 700 degrees Fahrenheit to keep lead dust and fumes out of the air.
In addition to using approved methods for containing any lead that may be released during renovation and painting, a contractor is also required to test the site after work is completed to insure no lead residue remains on surfaces such as windowsills, countertops and floors. And a record of the job must be kept by contractors for 3 years to prove all work was done in accordance with EPA approved methods.
Exceptions to the Rules
There are a few exceptions to these stringent requirements, for instance small jobs involving no more than six square feet in interiors and 20 square feet on exterior surfaces are exempt. Also housing for the elderly and disabled is exempt if no child under 6 years old is in residence or will be in residence there. Dwellings with no bedrooms such as an efficiency apartment are also exempt.
The DIY Loophole
If you are doing painting and renovations yourself, on your own property, you are not bound by these new rules. This doesn't mean you should just disregard the possibility of lead dust being created by the work you are doing. If you have children, especially children under 6 years old, you should be very careful they are not exposed to lead. Because a child's brain is still developing, lead is much more hazardous to them than to adults. Pregnant women should also avoid any lead in their environment for the same reasons.
Consumer paint has not contained lead in decades, however anyone working in an older home or building (built before 1978) may encounter old, lead-based paint. While lead-based paint does not present a hazard when intact (i.e. not chipping, peeling, chalking or otherwise disturbed), if you are contemplating a typical renovation or remodeling project know that it can disturb the painted surface and create lead dust. Special attention should be given when you prepare any old painted surface for repainting. Never use open burning methods, if you scrape, sand or remove old paint by any means you may release lead dust or debris. Lead is toxic and exposure to lead can cause serious illness, such as brain damage, especially in children. Pregnant women should also avoid exposure.
