Questions remain after huge hydrofluoric acid leak | News ...
Nov 08, 2012· The highly toxic hydrofluoric acid was released on 27 September at the Hube Global chemical plant in Gumi, about 200km from Seoul. The leak killed five workers at the plant and severely injured at least 18 others, including workers and emergency personnel.
The acid grade fluorspar is then transported to the hydrofluoric acid plants by ship, road, rail or barge. Here it reacts with sulphuric acid to form hydrogen fluoride gas. This is either collected and stored for use as a liquefied gas, or it can be diluted with water to produce aqueous solutions of hydrofluoric acid.
