When handling hydrofluoric acid, it is important to wear appropriate personal protective equipment (PPE). While the provided documents do not explicitly list the required PPE for handling hydrofluoric acid, they do offer general guidance regarding hazardous substances and the use of PPE. Based on this guidance and general safety practices, the following PPE is recommended when handling hydrofluoric acid:

• Eye Protection: Wear appropriate eye protection [1]. Safety glasses with side shields or a face shield are recommended to prevent splashes from contacting the eyes.
• Skin Protection: Wear gloves to handle wire cable [2]. Chemical-resistant gloves are essential to protect the skin from contact with hydrofluoric acid, as well as appropriate clothing to prevent skin contact [3].
• Respiratory Protection: If there is no other way to control the dust, wear an approved respirator [4]. Use respiratory protection equipment that meets requirements [5].

It is also important to note that contaminated clothing should not be worn outside of the workplace, and employers are required to supply facilities for drying and cleaning contaminated clothing [3].
