WASHINGTON — The National Transportation Safety Board launched a team Wednesday to investigate the breach of a rail tank-car and subsequent release of 17,000 gallons of chlorine Saturday at a facility in New Martinsville, West Virginia.
Initial information received by the NTSB about the accident characterized the event as a hazardous materials release only. As more information became available the agency learned that the shell of the rail tank-car breached, prompting the dispatch of three investigators to the scene.
NTSB Senior Hazmat Investigator, Paul Stancil has been designated as the Investigator-in-Charge. The on-scene team are experts in hazardous materials and metallurgy. Parties to the investigation are the Axiall Corporation (the tank-car owner) and the Federal Railroad Administration. The NTSB’s team has examined the tank-car, gathered relevant documents and interviewed personnel involved in the loading of the tank-car.
The on-scene phase of the investigation continues and the team’s planned operations include:
Interviewing plant personnel
Reviewing tank-car loading procedures;
Collecting relevant documentation;
Conducting tank-car damage assessment;
Identifying materials to be removed for metallurgical examination; and
Shipping the fractured section of the tank-car to NTSB headquarters in Washington for metallurgical examination.
Updates regarding the NTSB’s investigation will be made as developments warrant.
