Crews fight fire on Jefferson Hospital's roof

JEFFERSON HILLS, Pa. (KDKA) -- Crews responded to a fire on the roof of Jefferson Hospital on Tuesday. 

The small fire caused smoke to get into the hospital's upper floors through the air handling system, a spokesperson for Allegheny Health Network said in a statement. 

Some floors were impacted by smoke, but patient care areas weren't significantly affected and the building wasn't evacuated, AHN said. The impacted floors will be ventilated to clear any remaining smoke.  

In the meantime, the hospital is temporarily diverting patients from its emergency department as a precautionary measure. 

Photos from the scene show crews focused on the roof. AHN said the fire was related to construction, but didn't provide any other details on how it started. The fire was quickly contained, AHN said. 

No one was injured and AHN said "all patients and staff are safe."
