But you still needn't limit your own involvement in shooting. I asked Dr. Vickers about the possibility of exposure to lead, which might be transmitted to the baby through breast-feeding. The EPA would like to classify the lead emissions in a shooting range as a hazard, which would require even small ranges to go through a cleanup. But they've never proven any lead contamination in individual shooters. In range officers, yes.
Problems occur at the impact area.
There, lead is pulverized against metal backstops, and this powdered lead may get into the air and eventually into range officers' lungs. The lead acid vaporizes, and can be inhaled. But this can be easily solved, either through good ventilation or by wearing a mask while you're shooting. Obviously, once baby gets past the infant stage and starts crawling and playing with everything in sight, you'll need to exercise great care when handling and storing firearms and supplies. This is especially true of cleaning supplies, many of which are toxic if swallowed.
