The fire started around 4:15 p.m. Saturday on the 400 block of Main Street and affected at least two buildings. Firefighters say the only person inside made it out on their own.
It took several fire departments to help Darby crews put out the flames in a blaze that reached three alarms. The hot weather proved to be one of the day's biggest challenges.
"The temperature is in the '90s,” Darby's Fire Chief told Fox 29. “So it affects the firefighters wearing the heavy gear, obviously."
Firefighters also had to navigate a long-time problem for volunteer departments in Delaware County: not having enough people willing to do the job without getting paid, Darby’s Fire Chief calling it the “biggest struggle in the volunteer fire service right now.”
