The folks that had the contaminated workplace and clothing were in
effect melting lead on a stove. They weren't doing wire brushing or
other operations, so the lead dust must have come from melting the
lead.

While they do wire brushing in radiator shops, they were also using a
propane torch which was also way hotter than usual, so the lead dust
could have come from either operation.

Thus suggesting that Gordon's initial proposition--that melting lead at its
normal melting point doesn't create lead dust--is likely as not correct.

QED

I think it suggests that small amounts of lead in a soldering
operation wouldn't make much lead dust, but that melting larger
amounts (like for pouring into a small mold, even one as small as
making lead shot for hunting) requires more heat and would make lead
dust.
