Chemical storage warehouse fire.

FORT WORTH–Firefighters in North Texas are working to battle a fire at a chemical storage warehouse.

The four-alarm fire broke out around 12:30 Friday afternoon in Fort Worth.

Black smoke could be seen billowing in the sky for miles.

The storage warehouse holds furniture, chemicals, and a cardboard recycling facility.

Firefighters are working to contain the fire in one block section of the building because the amount of chemicals burning makes it hotter and more dangerous.

So far, no injuries have been reported.
