What PPE is required for handling hydrofluoric acid?

When handling hydrofluoric acid, it is crucial to use appropriate personal protective equipment (PPE) to prevent exposure to this highly corrosive and toxic chemical. The following PPE is generally recommended:

1. Eye and Face Protection: Use chemical splash goggles and a face shield to protect against splashes. Eye protection must comply with ANSI/ISEA Z87.1 standards for occupational and educational personal eye and face protection devices [1].

2. Skin Protection: Wear chemical-resistant gloves, such as those made from neoprene or nitrile, to prevent skin contact. Additionally, use a chemical-resistant apron or full-body suit to protect against spills and splashes.

3. Respiratory Protection: If there is a risk of inhaling vapors, use a respirator with an appropriate acid gas cartridge. Ensure that the respirator is NIOSH-certified and that a proper fit test is conducted [2].

4. Foot Protection: Wear chemical-resistant boots to protect your feet from spills.

5. Emergency Equipment: Ensure that an eyewash station and safety shower are readily accessible in the area where hydrofluoric acid is handled.

Employers must conduct a hazard assessment to determine the specific PPE requirements based on the concentration and quantity of hydrofluoric acid being used, as well as the specific tasks being performed [2]. Training on the proper use, limitations, and maintenance of PPE is also essential [3].
