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:
-
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, to prevent skin contact. Additionally, use a chemical-resistant apron or full-body suit to protect against spills and splashes.
-
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].
-
Foot Protection: Wear chemical-resistant boots to protect your feet from spills.
-
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].
Important Safety Note:
Always verify safety information with your organization's specific guidelines and local regulations.
