Axiall Corporation announced today that the cause of a Dec. 20 fire that occurred in the vinyl chloride manufacturing area of the company’s Lake Charles chemicals complex in Louisiana remains under investigation. The company also is working with outside engineering firms to assess the damage to the structure and the impact on production. The remainder of the Lake Charles facility was unaffected by the fire, and production continues as normal in those areas. The company praised the rapid response of Axiall emergency responders, Phillips 66, the Calcasieu Parish Sheriff’s office, local hospitals, Louisiana State Police, Louisiana Department of Environmental Quality, and other local, state and federal agencies -- as well as local residents who heeded a shelter-in-place-order issued by authorities. “We owe our sincerest thanks to everyone who responded to this fire,” said Jon Manns, plant manager at the Lake Charles complex. “This was a serious and unfortunate event, and we are thankful that none of our workers or contractors on site were seriously injured. We regret that this event has occurred." “We are in the process of conducting a full investigation into the cause of the fire,” Manns said. “We will continue to work with all appropriate governmental agencies as we continue our investigation."
