Handling lead in a solid form is not haz. as long as one uses common hygine and washes their hands.
Little bits of lead are constantly being abraded of any solid piece of lead.

This scare tactics regarding lead is unfounded. Granted lead is a harmful substance especially for young children, but all in all one stands a much greater chance of death and injury from many other sources.
So, exposure to lead pollution is involuntary and has huge but subtle social costs.
