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. This is essential as hydrofluoric acid can cause severe damage to the eyes and face upon contact.

2. Skin Protection: Wear chemical-resistant gloves, such as those made from neoprene or nitrile, as hydrofluoric acid can penetrate the skin and cause severe burns. Additionally, wear a lab coat or apron made from acid-resistant materials to protect your body.

3. Respiratory Protection: If there is a risk of inhaling vapors, use a respirator with an acid gas cartridge. In environments with high concentrations of hydrofluoric acid vapors, a full-face respirator or a supplied-air respirator may be necessary.

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

Employers are responsible for conducting a hazard assessment to determine the specific PPE required based on the concentration and form of hydrofluoric acid being handled, as well as the specific work environment [1].

Ensure that all PPE is properly maintained, fits correctly, and is used according to the manufacturer's instructions. Training on the correct use and limitations of PPE is also essential [2].
