A transformer that caught fire outside of an assisted living facility in Montgomery County forced the evacuation of more than 70 elderly residents Tuesday.
Fox 29's Bruce Gordan reports the transformer behind the Luther Park Assisted Living Facility caught fire around 2 p.m.
Fox 29 was told it had been smoking as early as Tuesday morning.
The transformer wasn't in use as the assisted living facility was using a generator.
Seventy-three residents were evacuated and were taken to another building on campus.
The granddaughter of one of the residents says the transformer fire sounded like a loud "bang," prompting everyone to start screaming.
PECO is now working to determine the cause of the fire. It's possible the fire may have been connected to water getting inside the transformer.
