Oak Ridge, Anderson County (WVLT) - More than one hundred workers evacuated from a Y-12 building Wednesday won't know until Wednesday night if they'll be allowed back in the building Thursday.
But Y-12 officials tell WVLT they fully expect the building to reopen Thursday.
The reason for the evacuation around 1:00 p.m., sparks were observed in a machine shop dust collector undergoing maintenance.
Y-12 says the dust was from a lithium compound.
A spokesperson says no fire or smoke was observed.
