Lack of control inside Bulgaria's largest steel maker Kremikovtzi has caused the January 10 blast that killed three people, a check conducted by the state General Labor Inspectorate (GLI) showed Tuesday.
Before completing their report, the GLI team examined closely the site of the blast, and took testimony of 21 people working at the metallurgical plant.
A Kremikovtzi worker and two firemen died in the explosion caused by gas leak. Just a day after the tragedy, another accident took place at the plant, but no one was injured.
