Thiruvananthapuram: State Industries Minister A C Moideen expressed grief over the death of a worker in a mishap at the state-run Travancore Titanium Products Limited Friday.
The minister said a probe has been ordered to ascertain if there was any "structural fault".
A 55-year-old man working at the factory was killed and another injured after a supporting structure of a raw material silo at its neutralisation plant near here collapsed on Friday morning.
The deceased was identified as senior process operator M P Hareendranath from Kannur.
Police said the concrete structure supporting the silo that stored calcium carbonate collapsed and an iron beam fell on the two persons and one of them died on the spot.
The minister said the neutralisation plant was designed by a Chennai-based firm and the construction work was completed in 2014.
The injured person, 28-year-old Suresh, stated to be a contract worker, has been admitted to the intensive care unit of the medical college and hospital here, hospital sources said.
Investigation is on to ascertain whether it was a case of negligence, the police said.
