help! my husband was at work the other day pulling copper wire & he came across a bag that said corrosive to the skin he didn t touch he but he thinks that maybe the wire he was pulling ran across the powder inside the bag now he has massive itchy red bumps all over he s hands knees & arms & a spot very close to his eye. he doesn t have insurance so I was wondering if you could help me figure out what it could be or possible how to treat something like that.
