Gas leakage kills three in semiconductor factory in S.Korea

Three workers were dead Thursday for gas leakage in a SK Hynix factory, which is now being built, local broadcaster YTN reported citing police officers.

Nitrogen-estimated gas was leaked at about 12:30 a.m. local time from a semiconductor factory of SK Hynix, the world's second- largest memory chip maker, in the city of Icheon, just southwest of capital Seoul.

Three workers, who were working to link ventilator pipes at the rooftop of the factory, were taken to hospitals by helicopter, but they ended up dying from suffocation.

Four other workers working at the rooftop suffered no injury.

On March 18, thirteen workers were slightly injured at the same factory for gas leakage. In July 2014, two workers received medical treatment after being exposed to silica dioxide at another factory to produce DRAM chips. Endi
