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.

经验教训—氟化物暴露

在进行实验研究时，实验室工作人员可能会遭受各种化学危害。此外，化学品的独特组合会产生个别化合物不会产生的危害。因此，研究人员可能缺乏适当的个人防护设备来充分保护自己。检查了最近发生的事件，其中研究人员在将六氟磷酸锂（LiPF ₆）溶解在碳酸二甲酯和碳酸亚乙酯的混合物中使用时，遭受了痛苦的氢氟酸（HF）灼伤。在环境条件下，LiPF ₆会产生HF，而HF本身不会轻易渗透到丁腈手套中。但是，碳酸盐混合物迅速渗透到丁腈手套中。该混合物通过丁腈手套携带了HF，可快速渗透。复合危害导致丁腈手套对这种实验的保护不足。这封信描述了这一事件，并讨论了适当的风险评估如何防止类似事件的发生。
