Abstract Bromine pentafluoride is a colourless or light yellow liquid. The material has a chemical reactivity similar to that of elemental fluorine. At temperatures above its boiling point, it is a colourless, pungent, and corrosive gas. Contact of the liquid or vapour with the skin or eyes causes painful, deep- seated, long-lasting burns. Relatively short exposures at high concentrations cause serious lung injury similar to that seen in phosgene-exposed individuals (e.g., pulmonary fibrosis, emphysema, atelectasis, bronchitis); lower concentrations cause watering of the eyes and difficulty in breathing within a few minutes. Based on the toxicological analogy of bromine pentafluoride with hydrogen fluoride, the maximum exposure limit (maximum admissible concentration) for bromine pentafluoride has been established at 0.5 mg/m3. Based on the results obtained from clinical studies of human exposure to hydrogen fluoride, a short-term exposure limit of 1 mg/m3 is proposed.
