This happened to a buddy of mine while he was cleaning out an old sub pump pit in a steel mill. He came across a pocket of ferric sulfate acid and it melted the tops of his boots and ate away at his flesh. He described it as the worst pain he’s encountered. The hospital took care of him tho with a nice script of oxys. I started calling him “the colonel” because the skin is “xtra crispy.”
