At least three people have been died and over 50 hospitalised of a suspected chlorine leak at the Mumbai Port Trust near Sewri on Wednesday.

As a precautionary measure, people residing in and around the area have been evacuated. The Cause of the leakage is being probed.
Chlorine gas is a respiratory irritant. It causes eye irritation as well as nausea, vomiting, dizziness and headache.
If exposed a long period of time and in strong concentration, it can lead to restlessness, throat irritation and excess salivation.
