Avoid and mitigate fumes. Buy a jug of D-Lead hand soap and laundry detergent and use it. Get regular blood tests for lead levels.

If you have or are regularly around small children, you need to be extremely diligent about the above. That goes for all you idiots obsessed with guns as well. Primers use lead styphnate and create lead vapor everytime you fire. Worse with rifles because your face is closer to the expelled gases.
