Hey Guys, New here - great forum, don't make a lot of baits - but I'm posting because I'm a toxicologist by training and just happen to run a state childhood lead poisoning prevention program. There have been some very good posts about what to worry about for lead poisoning here already. The only thing I have to add is that it take very little lead dust to poison a child. We've had cases of dust being brought in from work sites or hobby sites and contaminating a house and poisoning a kid. Having coveralls you use when working with lead and leaving them in your workshop is a good practice.
Secondly, depending on what state you live in, you may have access to lead dust tests. You can call your state lab and see if they have them. They are cheap (<$20 up here) - it is basically a like an alcohol wipe that you rub on your workbench (or whatever other site you want to test). That can act as a validation of your practices - are you REALLY doing all the stuff that you say you are doing?
Finally, if you work with lead, you should do a blood lead test every so often. Don't remember what the recommendations are - yearly or so - but the upshot is that the effects of the lead depend on dose. Like booze - a little makes you drunk, more makes you very drunk, more makes you vomit, enough will kill you. Catching lead when the levels are low in your blood will allow you to modify your techniques to reduce your exposure. You don't want your family discovering you had lead poisoning when they are burying you. Not particularly fair to your family or useful to you at that point. It is cheap, docs do it all the time, and it is a simple test.
