Three people were injured Thursday after a toxic gas leaked again at Samsung Electronics Co.’s chip plant in Hwaseong, Gyeongggi Province, the company said.

In January, one worker was killed and several others injured after they were exposed to poisonous hydrofluoric acid gas.

At 11:30 on Thursday, a small amount of the gas leaked while the workers were replacing a pipeline inside the Central Chemical Supply System.

They were slightly injured and treated at a nearby hospital, according to the company.

The colorless acute poison can damage the lungs and bones and even affect the nervous system.

In February, seven people, including three Samsung officials, have been indicted on charges of negligence in connection with the January incident in which one maintenance worker from the STI Service -- Samsung’s subcontractor -- was killed.
