When handling hydrofluoric acid (HF), 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:
-
Eye and Face Protection: Use chemical splash goggles and a face shield to protect against splashes.
-
Skin Protection: Wear chemical-resistant gloves, such as those made from neoprene or nitrile, as HF can penetrate skin and cause deep tissue damage. Double-gloving is often recommended for added protection. Additionally, wear a lab coat or apron made of acid-resistant material.
-
Respiratory Protection: If there is a risk of inhaling HF vapors, use a respirator with an acid gas cartridge. In situations with high concentrations, a full-face respirator or a supplied-air respirator may be necessary.
-
Body Protection: Wear a full-length lab coat or apron and ensure that all skin is covered to prevent exposure.
-
Foot Protection: Use chemical-resistant boots or shoe covers to protect feet from spills.
Ensure that all PPE is inspected for damage before use and replaced if necessary. Additionally, have calcium gluconate gel readily available as a first aid measure for skin exposure to HF. Always work in a well-ventilated area, preferably under a fume hood, to minimize inhalation risks.
These recommendations are generally applicable, but always consult your workplace's specific safety protocols and the Safety Data Sheet (SDS) for hydrofluoric acid for detailed guidance tailored to your specific situation.
Important Safety Note:
Always verify safety information with your organization's specific guidelines and local regulations.
