Two Mississippi Phosphates employees are recovering after being burned in an accidental gas release Wednesday. It happened around 8am when a weld near the top of a converter vessel suddenly ruptured.
The Mississippi Department of Environmental Quality is investigating the accident. The company said it continues to conduct air monitoring and had found no detectable concentration of gas or odor outside its facility.
"On-site gas levels fall below threshold levels of concern," the company said in a statement. "All appropriate governmental authorities and agencies have been notified and the group continues to closely monitor what appears to be an improving situation."
