Workers at 100 Challenger Road said the fire in the main electrical room knocked out power to the eight-story building.
“It was completely black,” one of them told CLIFFVIEW PILOT.
People were evacuated from the building in Overpeck Center, overlooking Overpeck Park, beginning around 8:20 this morning, another said.
Fire trucks from Ridgefield Park, Bogota and Little Ferry quickly arrived, along with ambulances, but no injuries were reported.
PSE&G was on the scene.
A firefighter at the scene said workers probably won’t be going back in today.
