Handling & Storage
Ammonium Bifluoride is highly corrosive and toxic. Always wear chemical-resistant gloves, full face shield, acid-resistant protective clothing, and respiratory protection where required. Use only in well-ventilated areas with emergency eyewash and safety showers nearby. Store in compatible containers (plastic or lined materials only—avoid glass and metals). Keep in a cool, dry, ventilated area away from acids and oxidizers.
