I'm sure that you've heard that inhaling 'things' like lead paint can cause problems. That's #1. #2, if small children happen to get their little mouths on this stuff, well, lead can harm them too. #3, different municipalities regulate who and how lead paint can be removed and disposed of. Soooo, before you go doing ANYTHING, including vacuming, check with your local municipality.
Did you have your home inspected? And if you did (or didn't), did you know there was lead paint? And if so, did you check into this BEFORE you signed your name 24x's at closing??? (I mention these because I usually recommend that prospective homebuyers 'play off' the cost of lead abatement into the Sale Price of the home. Plus, maybe you wouldn't have bought the home.)
Here are a number of posts on the Forum that talk about this issue from various angles. Do read them and see if they are of use.
PS: If you didn't hire YOUR OWN ASHI-Approved Home INspector, or didn't hire YOUR OWN Real Estate Attorney, when you buy your next home, be sure to do so. You'll find that those costs are a lot less than the cost of Lead Abatement ...
