Safety Protection: Operators should wear labor protection equipment. In severe cases, breathing difficulties and collapse may lead to cardiac paralysis and death. Since salicylic acid is excreted from the kidneys, it often causes acute nephritis. It is less toxic than phenol, but taking a large amount can cause vomiting, diarrhea, headache, sweating, rash, rapid breathing, acidosis and excitement. It irritates the skin and mucous membranes and has a corrosive effect because it can react with proteins in body tissues. It can cause corneal proliferation and peeling.
