Crews were battling a large fire at a manufacturing business in Tulsa, Oklahoma on Tuesday, local officials said.
Multiple photos of a large, black plume of smoke were circulating online, appearing to show the clouds emanating from the site of the blaze, just off the Arkansas River.
As of 11:20 a.m. local time, the Tulsa Fire Department was asking people to avoid the area.
Fire spokesperson Andrew Little said the fire is located at Royal, a manufacturing business, and crews are battling the blaze in a petroleum tank farm.
So far no injuries have been reported, Little said.
“Firefighters have made great progress and are continuing to work to extinguish the fire,” Little told USA TODAY just before 11:40 a.m. local time.
According to the business’ website, Royal is a “leading manufacturer and marketer of lubricants and greases made in the United States.” The company manufactures hundreds of different types of lubricating oils and greases using “biodegradable, synthetic, and mineral base oils for all types of applications including; mining, construction, oil and natural gas, steel mills, marine, industrial, agriculture, and transportation.”
Royal was acquired by Axel Christiernsson in 2018.
Firefighters reported they shut down Charles Page Boulevard between South Gilcrease Museum Road and South 33rd West Avenue. “Please find alternate routes of travel as firefighters work to get the fire under control,” the department posted on social media.
Little said no injuries had been reported, as of midday Tuesday.
The cause of the fire was not immediately known.
