In a significant rail incident early Tuesday, over 30 freight train cars derailed in Kentucky, with at least one car leaking a hazardous chemical, officials reported.

The derailment took place around 7 a.m. local time in a remote part of Todd County. Authorities issued a shelter-in-place order for a half-mile radius, which was lifted by 11 a.m.

Aerial photographs reveal the chaotic scene of freight cars piled against each other along the tracks in rural Kentucky, with several toppled onto their sides and debris strewn across the surrounding fields.

Among the derailed cars, one was leaking molten sulfur—a substance heated to a liquid state used in various industrial processes such as fertilizer production. The Environmental Protection Agency warns that molten sulfur can cause severe thermal burns and emit irritating gases like sulfur dioxide or hydrogen sulfide when disturbed.

It was unclear how many cars made up the entire train, though many remained on the tracks and were not derailed.

Multiple towns and state emergency management officials responded to the scene. No homes were immediately affected.

There were no reported injuries, according to Fox Nashville. Air quality in the area has been deemed safe, the outlet reported.
