BATON ROUGE, La. (AP) — A blaze inside a Louisiana refinery turned the night sky a shade of orange, sent a large plume of smoke into the air over Baton Rouge, and its heat could be felt across the Mississippi River.
ExxonMobil said its volunteer fire crews put out the blaze.
The fire erupted around 11:30 p.m. Tuesday, Baton Rouge Fire Department spokesman Curt Monte told reporters. No injuries were reported, he said.
“We’ve seen reports of people saying explosion. I can tell you there was no explosion," Monte told reporters at an early morning news conference Wednesday.
“We want the people to know that there has not been any off-site impact and we're going to continue to be out here as long as it takes to make sure that that doesn’t happen," he added.
Caleb Christopher Leblanc said a loud boom shook his windows on the other side of the Mississippi River from the refinery. After that boom, he said, “It sounded like a blowtorch.”
He walked up the levee near his house to take photographs and videos. “I could feel the heat from the top of the levee,” he said
“The big flame burned for about an hour,” Leblanc said.
ExxonMobil Baton Rouge tweeted that it has more than 300 emergency responders across its sites in Baton Rouge, and “our volunteer fire team members responded quickly and safely to control & extinguish the fire.”
ExxonMobil has been working with the fire department's hazardous materials unit to monitor air quality in the area, company spokeswoman Megan Manchester told reporters shortly after dawn Wednesday. Results so far have been “below detectable limits,” she said.
The fire was contained to the location where it started, Monte said. The glow of the fire could be seen from miles away, news outlets reported.
It wasn't immediately clear what caused the fire.
“Once deemed safe, our teams will go in to conduct a thorough investigation to determine the root cause of this incident and how we can learn from it,” Manchester said.
“Our response teams did exactly what they’re highly trained to do. They responded, they responded very quickly, so we’re very thankful for that," she added.
ExxonMobil is the largest manufacturing employer in Louisiana and its Baton Rouge refinery is the fifth largest in the country, WAFB-TV reported. It produces gasoline, jet fuel and more, as well as items such as paint and adhesives at the chemical plant.
Baton Rouge, Louisiana's state capital, is about 80 miles (129 kilometers) northwest of New Orleans.
