make sure your children do not inhale or ingest it. If your garage is attached to your house, find somewhere else to strip the paint, and don't wash your clothes in the same machine that you use to wash theirs. Lead is far more hazardous to children than adults.
You can make sure the kids don't ingest it by cleaning up after yourself. Not washing your clothes in the same LOAD of wash where they wash their clothes is prudent, but not washing your clothes in the same washer where they wash their clothes is overkill. Lead isn't going to jump out at you and bite you. You need to practice good hygiene, wash your hands after sanding the car, before eating etc. and don't wear your "sanding" clothes into the house. Don't keep an open drink container in the area where you are sanding. Just be reasonable and do intelligent things. Wear a respirator or at least a dust masks when sanding. The thing about dust masks is they don't offer much measurable protection. A fitted respirator with dust cartridges can be purchased at the hardware store. Learn to fit test it and change the cartridges after a reasonable period of use. I can't say what that is, but if the cartridges start looking dirty they probably are. If you can begin to taste anything in the air while wearing a respirator, stop what you are doing and change the cartridges. I am not a certified safety professional but have worked as an environmental manager and environmental engineer for over thirty years much of it around heavy metals so I am familiar with the topic.
