Safety and Handling

Hydrofluoric acid is one of the highest-risk reagents in laboratory use. The fluoride ion penetrates skin without immediate pain and causes serious systemic toxicity. Dermal exposure requires urgent medical attention—even in the absence of a visible burn.

• Handle exclusively in a fume hood with adequate extraction
• Required PPE: neoprene or PVC fluoride-resistant gloves, full face shield, acid-resistant lab coat, safety footwear
• Calcium gluconate gel must be available at the workstation before any operation begins
• Store in polyethylene, PTFE or polypropylene containers—not glass
• Keep away from strong bases, alkali metals and other incompatible materials
