Authorities are still working to find out the source of warning sirens that were heard in the Sulphur, Westlake, and Carlyss areas Thursday morning.
KPLC viewers reported hearing the sirens around 10:30 a.m.
An odor was also reported, but the source of that also remains a mystery.
Axiall held a drill Thursday morning in which sirens were tested, but it was over by 10:15 a.m., said Dick Gremillion, head of Calcasieu Homeland Security and Emergency Preparedness.
"The sirens that they have are not the type that range out very far from their locations," said Gremillion explaining that the sirens heard parishwide were not from Axiall.
His office has been working to find out the source of the sirens that occurred after the drill.
"We don't know if it was accidental or mechanical," Gremillion said.
Reports from residents reveal the emergency siren system was activated Thursday morning, but Gremillion and his crew as still not sure why or how that system sounded off.
"We have a manufacturer looking at it. We have programmers that program the system, and we have operators looking into it," said Gremillion, "So we should know in the next day or so."
As for the smell that was reported, Gremillion said it was likely regular plant emissions, but with low wind and high humidity those smells can be stronger than normal.
