(Washington, DC - December 4, 2002) Finding that the use of an incorrect hose led to an August 2002 chlorine leak near St. Louis, a new safety advisory issued today by the U.S. Chemical Safety Board (CSB) calls on other chlorine users to verify the materials of construction of their chlorine transfer hoses. The advisory grows out of an August 14, 2002, chlorine release at DPC Enterprises in Festus, Missouri. In that incident, a transfer hose failed catastrophically during the unloading of a chlorine rail car. Due to the malfunction of an automatic shutdown system, the leak continued unabated for several hours, eventually causing the release of about 48,000 pounds of toxic chlorine gas. Sixty-three people, including workers and nearby residents, sought hospital treatment as the result of the leak.
