A fire at the largest oil refinery on the East Coast turned the early morning sky a bright orange and yellow and awakened startled residents with explosions that shook homes Friday.
The fire broke out at the Philadelphia Energy Solutions Refining Complex around 4 a.m., spokeswoman Cherice Corley said.
By 9 a.m., emergency workers were still trying to control the fire, said Corley. Nearby residents were asked to shelter in place, and roads around the complex were closed to traffic.
News video shows a massive fireball shooting flames into the sky. There are four confirmed injuries, all minor, that were treated on site.
