VIDEO: Firefighters made progress Wednesday morning in reducing the size of a massive fire at the Marathon Petroleum refinery in Carson that sent massive flames and thick plumes of smoke into the air. The fire was visible as far away as Fullerton, with the thick black smoke rising hundreds of feet into the night sky. Some residents reported hearing a large boom in the area when the fire broke out just before 11 p.m. in the 2300 block of East 223rd Street. Both sides of the 405 Freeway and some surrounding streets were temporarily shut down in the area, but reopened within less than an hour. The refinery's own firefighters were on scene fighting the blaze and working to depressurize the system, while units from the Los Angeles County Fire Department arrived to assist.
