WASHINGTON (ICIS news)--The US National Transportation Safety Board (NTSB) ruled on Tuesday that a South Carolina train wreck and chlorine leak earlier this year that killed nine people was the fault of railroad employees who left a switch open.
The NTSB said the 6 January fatal accident at ?xml:namespace>
The impact ruptured one of the chlorine tank cars, and the resulting leak of chlorine gas killed the train conductor and eight people in the town.
“This was a tragic chain of events that did not have to happen and unfortunately resulted in the loss of life,” NTSB acting chairman Mark Rosenker said. NTSB, he said, “cannot stress enough the importance of following proper procedures and protocols at all times when operating these massive machines.”
Rosenker said NTSB also concluded that the conductor of the parked train failed to follow NS operating rules by not holding an end-of-work job briefing with the parked train crew, a process that NTSB said likely would have resulted in the siding switch being checked and reset as required.
NTSB did not, however, find any fault with the chemical tank cars involved in the wreck. In the immediate aftermath of the Graniteville accident there were calls in Congress for tougher construction standards for rail tank cars.
The NTSB did recommend that railroads position tank cars toward the rear of trains and reduce train speeds through populated areas to minimize impact forces in accidents and reduce the vulnerability of tank cars.
