Samsung issued an apology yesterday for the tragic accident that occurred at its semiconductor plant in Hwaseong on January 28th. A hydrofluoric acid leak killed one worker while injuring four others. It is said that around 3 gallons of the acid leaked. The colorless poison damages the lungs and bones and eventually harms the entire nervous system. While the incident occurred around 11:00PM that night, Samsung failed to report it until 3:00PM the next day.
