My father is a marble cutter. Because of long-term contact with sewage, his hands are rotten, and the rotten parts are as rotten as corns.

I'm in this business, too, but I haven't seen the kind you said. Because the main component of natural marble is calcium carbonate, contact is not very harmful to people. If it is harmful, it is to cut artificial stone, which is composed of stone powder and resin, as well as other chemicals and so on. This is harmful. If the gas discharged from the over-circulation pool for cutting artificial stone is thick enough, it will really kill people.

Last year, there was a large artificial stone factory in Yunfu. I didn't notice the gas when cleaning the mud in the pond. The first worker fainted, and the two people who went down to save people were also poisoned. Three people died in time because of emergency treatment.

If what you said really happened, I think your father cut the artificial stone. Go to the hospital as soon as possible, and wear waterproof glue gloves and cloth gloves before cutting anything, which will be waterproof and not easy to break.
