TROY — A small chemical spill prompted a building to be evacuated at RPI Thursday afternoon, Troy Fire Chief Tom Garrett said.

No one was hurt when about a liter of a potentially hazardous chemical spilled in a room at the college's biotech building, Garrett said.

The chemical's odor permeated the building, triggering the evacuation, Garrett said.

One woman went to the school's medical center, though she was expected to be fine, the chief said.

The spill occurred around 12:45 p.m., Garrett said, adding that a HAZMAT crew was called in to clean up the scene.

For precautionary reasons, the building will be closed for the day Thursday and reopen Friday morning, said Michael Mullaney, an RPI spokesman.
