The storage and use of Chlorine gas versus on-site generation is an international problem. Here is an article from Mumbai, India. "Nearly 103 persons fell sick early today after inhaling chlorine gas leaking from a cylinder stored in Bombay Port Trust (BPT) premises at Sewri prompting BPT, police and Brihanmumbai Municipal Corporation to begin a joint probe into the incident.
All the affected persons were taken to King Edward Memorial hospital, JJ hospital and BPT hospital, police and fire brigade sources said, adding, they included college students, BPT staff and firemen.
The condition of eight persons at JJ hospital was said to be critical. However, there are no casualties so far, Dean of JJ hospital T P Lahane told reporters.
Some of the affected persons were discharged after getting treatment. Currently, 78 persons are recuperating out of which eight are in the Critical Care Unit due to respiratory problems and 14 in Medical Intensive Unit for throat problems, Lahane said."
It is time for global adoption of “inherently safer technology” (IST).
