Natchaug Hospital in Mansfield Center failed to make accommodations for a former employee who claims the installation of new carpeting in the facility caused her to have difficulty breathing and other adverse health effects, according to a discrimination suit levied against the hospital.

According to the suit, which was filed in federal court on Monday, Mary Montany began smelling strange odors emanating from the facility’s ventilation system in 2009. The odors caused Montany to fall ill with symptoms that included swelling and redness in her eyes and nose, headaches, vertigo, nausea, a burning sensation in her lungs and throat, and difficulty breathing.
