exposure to trifluoroacetic acid requires protection by wearing chemical protective gloves, goggles and protective masks to avoid irritation and injury to the skin, eyes and respiratory tract.

should avoid directly inhaling the smell of trifluoroacetic acid, because its vapor has an irritating effect on the respiratory tract and may cause dizziness, nausea and other symptoms. In the process of contact with trifluoroacetic acid, a well-ventilated working environment should be maintained to avoid long-term exposure to high-concentration trifluoroacetic acid gas.

do not use trifluoroacetic acid mixed with oxidants, alkaline substances or flammable substances to avoid accidents caused by chemical reactions.
After using trifluoroacetic acid,
