‘Over 60% of styrene vapour leak from plant polymerised’

AMARAVATI: Over 60 per cent of the styrene vapour that leaked from a tank in LG Polymers near Visakhapatnam on Thursday, killing at least 11 people, has polymerized so far and all chemical tanks in the plant are safe, District Collector V Vinay Chand said on Friday.

In a report submitted to Chief Minister Y S Jagan Mohan Reddy during a video conference, the Collector said it might take 18-24 hours for the remaining vapour to polymerise, a process to bring down the temperature below 20 degree Celcius where styrene remains in its original liquid form, and turn safe.

"We have taken all measures to plug the leak completely and experts are closely monitoring the situation. The situation is now fully under control," the Collector added.

On Thursday, he had said a technical glitch in the refrigeration unit attached to the two styrene tanks at the plant had caused the vapour leak.

"Styrene monomer is normally in a liquid state and is safe below a temperature of 20 degrees Celsius. But because of the malfunctioning of the refrigeration unit, the chemical started gasifying," the Collector, quoting a preliminary report by the Factories Department, had said yesterday.

On Friday, Chief Secretary Nilamsawhney, who was camping in Visakhapatnam overseeing the relief measures, also said the situation was totally under control and that all tanks in the unit were safe.

Responding to this, the Chief Minister directed the officials to speak to the engineers and explore steps to utilise the raw material and chemicals in the plant fully.

"Also, take steps to remove the chemicals from the plant to another place," he said.

Meanwhile, Chief Secretary Nilamsawhney issued an order appointing a high-level probe into the causes behind the gas leak and suggest measures to improve the protocol for industrial safety of similar types of plants.

Special Chief Secretary (Environment and Forests) Neerabh Kumar Prasad will be its chairman and Pol

lution Control Board Secretary Vivek Yadav will be the member-convenor.

Special CS (Industries), Visakhapatnam District Col

lector and city Police Commissioner will be the other members.
