Rashtriya Ispat Nigam Limited (RINL) Director (Operations) Umesh Chandra on Monday visited the Blast Furnace-3 and made a preliminary inquiry into the blast at Visakhapatnam Steel Plant (VSP) that injured five employees on Sunday.

He reportedly gathered information on power outage that was believed to have caused spillage of slag, leading to hospitalisation of five employees. Some of the workers suggested measures for uninterrupted power supply.

The condition of four employees, who were admitted to a corporate hospital, was improving. According to doctors attending on them, they might be discharged in a day or two.

All-India Trade Union Congress national vice-president D. Adinarayana said lack of emergency generator caused the accident.
