My Brother in law work at a steel place spraying Red Lead Primer paint before it was baned. He passed on lead poisoning to my sister via clothing. She was pregnant at the time. Her Twins were born with lung defects that they allmost didn't survive. Whole family had to be checked for several years. They didn't have a clue. She died of cancer, any connection? Nobody knows or ain't saying. Do what you want, but I like to error on the side of caution.
