Winona State (Minn.) University faces a proposed fine of nearly $25,000 for workplace safety violations related to the removal of asbestos.

The state Occupational Safety and Health Division says the university repaired or replaced insulation in dormitories and other areas of campus without taking the necessary precautions to protect workers from asbestos.

The school is contesting the allegations. Assistant vice president Cristeen Custer says the school is cooperating with OSHA, according to the Associated Press.
