More than 30 school students were affected after exposure to fumes from a storage tank at JSW Energy’s thermal power plant in Maharashtra’s coastal Ratnagiri district on Thursday, police said. However, in a statement Thursday evening, JSW Energy said its thermal plant at Ratnagiri does not have any gas storage facility and is not involved in the incident as reported in the media.

The students are from the Jaigad Vidya Mandir school, which is near the plant, a police official told PTI. Of the 250 students who were in the school, more than 30 complained of eye irritation after exposure to fumes coming from the cleaning process of the tank, police said. Some of them were taken to a nearby hospital.
