BROOKLYN HEIGHTS, Ohio

On Monday morning, a huge factory fire lit up the sky near I-480 and I-77 with flames and smoke that could be seen for miles.

No one was hurt, but there are surprising new details about that building in the 1400 block of Valley Belt Road.

"It did not have sprinklers or an alarm system," said Jim Wheeler, Independence Fire Department's Assistant Chief.

Wheeler said an off-duty police officer first reported the fire around 3:30 a.m. By the time crews arrived, the flames were eating through the roof.

The plastics inside, which had given the North Shore Strapping Company its business for years, were serving as fuel.

"Basically they have bubble wrap and shipping supplies," said Assistant Chief Wheeler. "So it's a petroleum-based product. Plastics have a lot of petroleum-based chemicals in them so they burn hot, and they burn very fast."
