When handling hydrofluoric acid, it is crucial to use appropriate personal protective equipment (PPE) due to its highly corrosive nature and potential to cause severe chemical burns and systemic toxicity. The following PPE is recommended:

1. Eye and Face Protection: Use chemical splash goggles and a face shield to protect against splashes. Eye protection should meet the requirements of standards such as ANSI Z87.1 or CSA Z94.3 [1].

2. Skin Protection: Wear chemical-resistant gloves, such as those made from neoprene or nitrile, to prevent skin contact. Ensure that gloves are inspected for any damage before use [2]. Additionally, wear a lab coat or apron made of acid-resistant material to protect your body and clothing.

3. Respiratory Protection: If there is a risk of inhaling vapors, use a respirator with an acid gas cartridge. In situations with high concentrations or poor ventilation, a full-face respirator or a self-contained breathing apparatus (SCBA) may be necessary [3].

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

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

Always conduct a hazard assessment to determine the specific PPE requirements for your work environment and ensure that all PPE is properly maintained and used according to the manufacturer's instructions. Training on the correct use and limitations of PPE is also essential [6].
