Graniteville, South Carolina chlorine release (2005)
On January 6, 2005, a Norfolk Southern freight train derailed in Graniteville, South Carolina, rupturing a tank car carrying 90 tons of chlorine gas. The gas killed 9 people and sent hundreds to hospitals within hours.
More than 5,400 residents were evacuated; the town's economy and local businesses suffered for years.
The disaster pushed regulators and industries to reduce bulk chlorine gas storage and transport, and accelerated utility conversions to safer disinfection methods.
Graniteville shows the catastrophic consequence of chlorine gas in bulk near population centers, the exact hazard Austin is removing from the Ullrich plant.
