GEISMAR, La.—Louisiana State Police say a reported explosion has started a fire at a chemical plant.
Capt. Doug Cain says the fire broke out at The Williams Companies Inc. plant in the town of Geismar.
The plant makes highly flammable gases that are basic building blocks in the petrochemical industry.
The town is southeast of Baton Rouge.
Residents in the surrounding area have been asked by state police to stay indoors and close all windows and doors.
Cain says he doesn’t know how many people were hurt, but sees ambulances taking a couple of people from the plant.
The company’s website says the plant puts out about 1.3 billion pounds of ethylene and 90 million pounds of polymer grade propylene a year.
