(WPXI) – The cause of a fire in Donora this morning is under investigation. Firefighters battled a house fire in Donora Tuesday morning. Washington County dispatchers say that calls came in for a reported structure fire in the 1200 block of McKean Avenue around 5:30. A woman and her sister told our news partners at Channel 11 – that they were inside the home when the fire broke out. “I smelled something burning, opened up my bedroom door, our whole house is full of smoke, so I got my sister. We got out, and the whole back of my house was on fire,” said homeowner Bobbie Fygolah. Several trucks lined 13th Street as crews searched the top floor for hot spots. Street crews had to salt and monitor the roads to keep firefighters safe, as ice formed in several areas. There were no injuries but Donora’s fire chief believes the house is a total loss.
