News has emerged that the head of Samsung’s engineering (KRX: 028050) unit has, reportedly had to step down as a result of an accident that occurred in South Korea last week.

The incident, a water tank explosion, led to the deaths of three workers at the plant inside Samsung Fine Chemicals in Ulsan, about 410 kilometers southeast of Seoul.

The Yonhap News Agency reports that Samsung Group said Thursday that it fired the chief of its engineering unit Samsung Engineering Co., holding him responsible for the explosion.

A water tank burst during a stress test at a polysilicon plant construction site, which also injured more than 10 workers. The news agency said a 1,300-tonne water tank was being filled to detect any cracks as part of a stress test, but erupted at around the 1,000 tonne mark.

Workers were hit by flying debris and the tank’s supporting structures.

Samsung Engineering, a unit of conglomerate Samsung Group, was building the tank for SMP, a joint venture between Samsung Fine Chemical and MEMC of the United States.

Power Engineering International has placed a request for more information with the company and hopes to provide more detail on the news shortly.
