Intense flames tore through the loading zone of a commercial building in Ontario late Wednesday, forcing employees still in the building to run and leaving firefighters searching for the cause of the fire.
The Ontario Fire Department responded to a fire burning near the external area of a building on Proforma Avenue, near the Ontario Airport, at around 11 p.m. on Wednesday night.
The building belongs to a business called U.S. Merchants, and the designed manufacturing and distribution facility was filled with plastic materials and wooden pallets that fueled the fire.
Flames reportedly first erupted in a truck yard on the west side of the building, before they spread to the interior of the building.
The fire quickly escalated to a two-alarm, then three-alarm fire, with 64 personnel in total on scene to fight the flames.
