 A series of explosions and a massive fire engulfed a recycling plant in Salt Lake City early yesterday morning. Seventy firefighters were called to the scene along 900 South after the fire was reported at around 1230 a.m. and found a huge column of flames and smoke rising from the facility when they arrived. Officials say there were propane tanks inside the building, though it's not clear if they caused the explosions that were reported. After several hours, fire crews were able to get the blaze under control and no injuries were reported. There's no word on how the fire started.
