Explosion in Louisville: Shelter-in-place ordered after building explodes in Kentucky neighborhood

At least 11 people were injured in an explosion at a manufacturing facility in Louisville, Kentucky, police said.

According to Louisville Metro Emergency Services, a “hazardous materials incident” was reported at the address of a Givaudan Sense Color facility on Tuesday afternoon.

The University of Louisville Hospital said it had received seven patients from the explosion, including two in critical condition. The injuries included burns and explosions, a hospital official said.

The cause of the explosion, which occurred around 3 p.m. local time, is currently unknown, officials said.

All the injured are employees of Givaudan Sense Colour, a natural dye factory, officials said.

One person trapped after the explosion was rescued, while several others were evacuated, officials said.

There were no fatalities in the incident.

Drone footage taken by WHAS, an affiliate of Louisville ABC, showed extensive damage to the facility.

Residents within two blocks of the facility, located at 1901 Payne St., have been evacuated, officials said.

A shelter-in-place order was also issued for people within 1 mile of the facility, but has since been lifted, officials said.

Agents from the Louisville Division of the Bureau of Alcohol, Tobacco, Firearms and Explosives are responding and assisting with the “critical incident,” the agency said.

Air monitoring is clear at this time, officials said.

Kentucky Governor Andy Beshear urged people in the area to follow guidance from local officials “as emergency responders work to secure the area” and said he is “praying for the safety of everyone involved.”

Givaudan Sense Color makes colors used in food and other applications, according to its website.
