Athens, OH – News, ATHENS, Ohio — Ohio University said it is closing its Ohio Coal Research Center, a week after it was evacuated because of high carbon monoxide levels.

The university said the problem was caused by a piece of research equipment that wasn’t properly adjusted. Some of the workers in the building got sick from the gas last Monday.

The research center is affiliated with the university’s College of Engineering and Technology and explores new ways to use coal to power fuel cells.

Provost Kathy Krendl said the university is conducting a thorough investigation into the situation.
