When handling hydrofluoric acid, it is crucial to use appropriate personal protective equipment (PPE) to prevent exposure and potential injury. 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 eye damage.

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 material to protect your body.

3. Respiratory Protection: If there is a risk of inhaling vapors, use a respirator with an acid gas cartridge. Ensure that the respirator is NIOSH-certified and fits properly.

4. Foot Protection: Wear closed-toe shoes with chemical-resistant covers to protect your feet from spills.

5. Emergency Equipment: Ensure that an eyewash station and safety shower are readily accessible in case of exposure.

Employers are responsible for providing the necessary PPE and ensuring that employees are trained in its proper use, maintenance, and limitations. Regular hazard assessments should be conducted to determine the specific PPE requirements based on the level of exposure and the work environment.

It's important to note that these recommendations are based on general safety practices and may need to be adjusted based on specific workplace conditions and regulations.
