An explosion at the Givaudan Sense Colour manufacturing plant in Louisville on Tuesday afternoon resulted in 11 workers being hospitalized, although no fatalities were reported. The explosion caused significant structural damage to the facility and shattered windows in nearby homes and businesses. First responders rescued one individual who was trapped inside the building. Mayor Craig Greenberg confirmed that air monitoring showed no immediate signs of toxic chemical release, but investigations are ongoing to determine what substances were involved. Residents within a two-mile radius were initially ordered to shelter-in-place, a precaution that was lifted later in the day. This incident marks the second explosion at the plant, with a previous fatal event occurring in 2003.
