ABF or Ammonium Bifluoride is sold in aqueous solutions or in solid form. The solutions are colorless, clear liquids with a slightly pungent, sharp odor. In its solid form, it is a white crystal.
ABF is a corrosive chemical, which can severely burn and irritate the skin and eyes, possibly resulting in permanent damage to the eye. Breathing in ABF could severely burn and irritate the nose, lungs and throat. This could cause shortness of breath, nosebleeds, excess coughing and wheezing.
ABF is used to clean and etch metals before further processing. It is essentially utilized in the cleaning of ceramics and bricks, in glass etching and as an acidifier in oil wells. In addition, ABF may be utilized for pH adjustment in the processing of industrial textile or laundries.
Ingestion or inhalation of large amounts of ABF could result in nausea, loss of appetite and vomiting. Additionally, long term or very high exposures could lead to fluoride poisoning. This usually has symptoms such as convulsions, weakness, stomach pain and death. Repeated or long term exposures could lead to deposits of fluorides in the teeth and bones. This condition is known as fluorosis and could bring about discoloration of teeth, pain and disability.
