When handling hydrofluoric acid (HF), it is crucial to use appropriate personal protective equipment (PPE) to prevent exposure to this highly corrosive and toxic chemical. The following PPE is recommended:
-
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].
-
Skin Protection: Wear chemical-resistant gloves, such as those made from neoprene or nitrile, as HF can penetrate skin and cause severe burns. Additionally, wear a lab coat or apron made of acid-resistant material to protect your body [2].
-
Respiratory Protection: If there is a risk of inhaling HF vapors, use a respirator with an acid gas cartridge. Ensure that the respirator is NIOSH-certified and that a proper fit test is conducted [3].
-
Foot Protection: Wear chemical-resistant boots to prevent exposure to spills on the floor.
-
Emergency Equipment: Ensure that an eyewash station and safety shower are readily accessible in the area where HF is used.
Employers must conduct a hazard assessment to determine the specific PPE requirements based on the concentration and form of HF being handled, and ensure that all PPE is properly maintained and employees are trained in its use [2].
Important Safety Note:
Always verify safety information with your organization's specific guidelines and local regulations.
