On January 21, 2019, two laboratory employees were dissolving metal fuel samples in a fume hood when a reaction caused some of the acidic sample solution to be expelled from a Teflon beaker. The solution, which contained nitric, hydrochloric, and hydrofluoric acids, contacted both employees.
Lessons learned: Be sure to use non-direct line-of-sight visual inspection methods when working with chemicals in fume hoods and ensure the fume hood sash is at an appropriate height. This can prevent any hazardous solutions from contacting personnel when chemical reactions occur and are expelled from the container (in this case a Teflon beaker).
