You've gotta do one of two things now.
1) get Tyvek suits and wear them while doing your scraping. Put the used ones in a bag with the paint chips and your scrub pads and everything goes out during the next hazardous waste day in your town.
2) Wear a set of your oldest clothes when you're working on this; those go in the bag at the end of the job. Don't was them. If you're put clothes through the laundry already, run the washer with nothing in it.
Do the work on top of plastic sheeting. At the end of the job, it all goes in the bag.
Do you have a much younger brother or sister? don't let them near this.
At the end of the job, get yourself tested. (This is starting to sound like sex, isn't it?)
