The fire was reported at about 4:20 p.m. at Sims Metal Management in the 1800 block of Monterey Road. Fire Capt. Debbie Ward said about 55 firefighters were involved in the single-alarm response, which also included a hazardous materials task force.
She said the fire burned a 300-foot by 300-foot pile of recyclables. Although there were no active flames by early evening, crews were waiting to get to the bottom of the pile before calling the fire under control, Ward said.
She said the fire was officially declared controlled at 8:05 p.m.
Bay Area Air Quality Management District officials responded to the fire as a precaution, but it was determined there was no hazmat risk, according to Ward.
No injuries were reported and the cause of the fire appears to be accidental, Ward said.
