Meanwhile, officials have confirmed that the chemical that leaked from the plant was styrene. The spread of styrene monomer vapours in the air depends on the wind speed and officials are working to neutralise the air with chemicals such as 4-tert-Butylcatechol (TBC), a senior official of the department of factories said on Thursday.
“Officials are using inhibitors to neutralise the vapours and they are reducing gradually. However, it has not been arrested fully. They are using neutralisers such as TBC (4-tert-Butylcatechol (TBC),” the joint chief inspector of factories, Visakhapatnam, J. Siva Sankar Reddy, told a news agency.
“The spread may be two or three-kilometers wide. Right now we cannot exactly determine the area of the spread because it will depend on the wind speed. High wind speed will mean the spread will be more,” the official added.
A special chemical accident team from the National Disaster Response Force has been deployed for search and evacuation work, assisting local people, and administration on site.
Styrene, chemically known as ethylbenzene, is a synthetic chemical that evaporates easily and has the texture of a colourless liquid. This chemical is commonly used in the manufacture of plastic products used in food packaging, rubber, plastic, insulation, fiberglass, pipes, and automobile parts.
The harmful effects of styrene monomer include severe irritation to eyes and mucous membranes, as well as gastrointestinal effects. Exposure to styrene can also affect the central nervous system, cause headaches, fatigue, weakness, and depression.
G. Srijana, the commissioner of Greater Visakhapatnam Municipal Corporation (GVMC), said, “According to the primary report, polyvinyl chloride gas (or may be Styrene) leaked from the LG Polymers plant at around 2:30 a.m. on Thursday. Hundreds of people have inhaled the toxic gas and fallen unconscious or have breathing issues.”
The commissioner added, “The GVMC is trying to minimise the effect by blowing water through most blowers. Public address systems have been pressed into service asking people to use wet masks.”
