A single breached chlorine tank could, according to the Department of Homeland Security, lead to 17,500 deaths, 10,000 severe injuries and 100,000 hospitalizations.

A crash in Graniteville, S.C., this month ruptured a chlorine tank, leaving nine people dead and 234 injured.

If the chlorine tanks had opened much of the population of the city would have been killed, but the emergency was successfully dealt with by fire brigade.
