Narendra, brother of one of the deceased, said, "...I learned that they were poisoned by gas inside the tank. I went to the scene, but the police didn't let anyone enter... they are saying that the first person went in, then he was overcome by gas and collapsed inside. Another went to rescue him and also collapsed inside. Then a third went to rescue them and got stuck inside as well. It happened one after another... if we talk about fault, it lies with the factory owner... they didn't provide any equipment... I have so many responsibilities, but I am unemployed myself..."

It may be recalled that a similar incident had occurred in New Ashok Nagar after a worker died while cleaning a septic tank.
