The fire broke out in an air handler on the roof due to a mechanical failure around 12 p.m. Monday, Denville Police Capt. Jeffrey Tucker said. Once the fire was doused, the heavy smoke spread through a portion of the building and led to patients’ evacuation, Tucker said. A total of eight patients in the emergency room were transported to St. Clare’s Dover campus, while others were moved to various areas of the hospital that weren’t affected in the fire, Tucker said.
