Hydrofluoric acid effects on health and the environment
Hydrofluoric acid and HF vapor can cause severe burns to the eyes, which may lead to permanent damage and blindness. At 10 to 15 ppm, HF vapor is irritating to the eyes, skin, and respiratory tract. Exposure to higher concentrations can result in serious damage to the lungs, and fatal pulmonary edema may develop after a delay of several hours.
Hydrofluoric Acid Lab-Specific Standard Operating Procedure
Store hydrofluoric acid as indied in safety data sheets (SDSs). Ensure labels on original bottles remain legible and prominently displayed to identify contents. Ensure both original and secondary containers remain intact and are stored with tight-fitting caps or lids.
