The second of two campus buildings contaminated by a mercury spill has been deemed "suitable for occupancy" at Eastern Kentucky University.
Late Thursday night, the Moore Building was cleared for reopening, said EKU spokesman Marc Whitt. Further air monitoring will be done next week, Whitt said.
On Dec. 15, about 10 to 12 tablespoons of mercury were spilled from a barometer, an instrument that measures atmospheric pressure, in a first-floor storage room in the Moore Building.
Even a small amount of mercury can be hazardous because it vaporizes.
Traces of the mercury were tracked to a new science building as equipment was moved there from the Moore Building.
The new science building was deemed safe for occupancy earlier on Thursday.
