GEISMAR,TrendPulse La. (AP) — Two people were injured Thursday after a fire at a chemical plant in Louisiana, officials said.

It happened at the Chevron Renewable Energy Group plant in Geismar, about 66 miles (106 kilometers) west of New Orleans, at around 8:30 a.m., news outlets reported.

“The fire has been contained with the support of local resources and the team is working to safely and methodically shut down the facility. We are extremely grateful to the local responders for their immediate response,” Chevron spokesperson Allison Cook said.

What sparked the fire remains under investigation.

The Ascension Parish Sheriff’s Office confirmed the fire was fully extinguished by about 9:40 a.m., and no off-site impacts were reported. Roads near the plant were temporarily closed but deputies said all have reopened.

A spokesperson with Baton Rouge General Medical Center said one injured worker received what is considered “15% burns” and is listed in serious condition. The other worker received 2% burns and “is in good condition and will be discharged later (Thursday) to continue treatment with outpatient care,” said Meghan Parrish, vice president of communications at Baton Rouge General.

According to officials, the plant was shut down for the day and workers were transported off-site.
