Explosion at Kentucky business injures 11 workers, shatters windows in surrounding neighborhood

At least 11 employees were taken to hospitals after an explosion at a Louisville, Kentucky, business that produces natural color for foods and drinks. The explosion on Tuesday happened at Givaudan Sense Color. News video footage showed an industrial building with the middle section burned and partially collapsed. The cause of the explosion remains unknown. Louisville Metro Emergency Services had urged people within a mile of the business to shelter in place, but that order was lifted about two hours after the explosion. The University of Louisville Hospital treated seven of the people injured and two of them are in critical condition.
