LOUISVILLE, Ky. (AP) – An explosion at a Louisville, Kentucky, business on Tuesday sent at least 11 employees to the hospital.
The explosion occurred at a company that produces natural colors for food and beverages. News video showed a partially collapsed industrial building with its central section on fire.
“The cause of the explosion is unknown at this time,” Louisville Mayor Craig Greenberg said. No one was killed in the explosion, he added.
Greenberg said officials spoke with employees inside the plant. “They initially told us that everything was normal activity when the explosion occurred,” he said.
Louisville Fire Chief Brian O’Neill said air monitoring began immediately after the explosion and “there are no indications of any type of chemical issue in the air throughout the area at this time.” O’Neill added that fire officials “still don’t know exactly what type of leaks may occur or may be in progress.” He called on residents to remain calm.
Louisville Metro Emergency Services had asked people within a mile of the business to shelter in place, but that order was lifted about two hours after the explosion.
