Abstract

Accidental hydrofluoric acid (HF) splashes often occur in industrial settings. HF easily penetrates into tissues by initial acid action allowing fluoride ions to penetrate deeply, chelating calcium and magnesium. Resultant hypocalcemia and hypomagnesemia can be fatal. This report describes the utilization of Hexafluorine--a hypertonic, amphoteric, chelating decontamination solution--in workplaces where water decontamination followed by calcium gluconate inunction failed to prevent HF burns and systemic toxicity. Between 1998 and 1999, 16 cases of ocular and dermal HF splashes with either 70% HF or 6% HF/15% nitric acid (HNO3) were decontaminated with Hexafluorine at the worksite. HF burns did not develop and medical treatment other than initial decontamination was not reQuired in 12/16 (75%). In 7/16 (44%) cases, lost work time corresponded to duration of hospital observation (mean < 1 d).

一种用于眼部和皮肤氢氟酸飞溅的紧急去污的改进方法。
在工业环境中经常发生意外的氢氟酸溅溅。HF通过最初的酸作用很容易渗透到组织中,使氟离子深入渗透,螯合钙和镁。由此导致的低钙和低镁血症可能是致命的。本报告描述了在工作场所使用六氟(一种高渗、两性、螯合的去污溶液),在工作场所,水去污后用葡萄糖酸钙涂敷未能防止HF烧伤和全身毒性。在1998年至1999年期间,16例眼部和皮肤的HF飞溅用70% HF或6% HF/15%硝酸(HNO3)在工作场所用六氟净化。在12/16(75%)中,没有发生HF烧伤,除了初始去污外不需要进行药物治疗。在7/16(44%)的病例中,损失的工作时间与住院观察时间相对应(平均< 1 d)。
