City Hall evacuated over fumes

CHATTANOOGA (WDEF) – City hall was evacuated this morning over a possible gas leak.

Employees reported smelling a chemical odor around 8 AM.

But firefighters found the fumes were not gas, but the chemical styrene instead.

A subcontractor sprays styrene to line stormwater pipes underground and the fumes came in through openings under city hall.

It is not hazardous, just smelly.
