Meanwhile another person is in a critical condition and is undergoing treatment at a hospital.
According to locals, the tank was not being used by the owners for a long time. The incident occurred when one worker out of the four deployed to clean the tank fell unconscious after entering into it. The other three workers jumped in to rescue him.
