We are hearing from multiple reliable sources that the woman burned in a flash fire at Guardian Automotive is not doing well.
    The names still haven't been released, but the woman and a man were flown to Vanderbilt University Hospital with serious  burns.
    The accident happened in a paint booth at the plant Monday afternoon.
    Investigators says someone knocked over a halogen light, igniting vaporized acetone, which is a cleaning solvent.
    The plant was evacuated for about an hour.
    This is the second evacuation because of a fire this year.
    Back in March, a welding torch ignited some paint.
    Guardian Automotive makes cars parts, such as windshields and grilles.
