Laboratory workers are potentially exposed to a wide range of chemical hazards while performing experimental research. Moreover, unique combinations of chemicals can generate hazards that the individual chemical compounds would not produce. Thus, researchers may lack proper personal protective equipment to adequately protect themselves. A recent incident is examined in which a researcher suffered a painful hydrofluoric acid (HF) burn when working with a solution of lithium hexafluorophosphate (LiPF6) dissolved in a mixture of dimethyl carbonate and ethylene carbonate. Under ambient conditions, LiPF6 can produce HF, which by itself does not easily permeate nitrile gloves. However, the carbonate mixture rapidly permeates nitrile gloves. The mixture carried HF through the nitrile gloves allowing for rapid permeation. The compounding hazards led to nitrile gloves being inadequate protection for such an experiment. This Letter describes this incident and discusses how a proper risk assessment could prevent similar incidents from occurring.
