The National Transportation Safety Board (NTSB) 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.
