A massive fire that prompted the “largest response” in the history of the Phoenix Fire Department burned multiple recycling yards and commercial structures on Saturday in west Phoenix, threatening nearby homes and filling the sky with clouds of smoke and flames.
Fire officials received reports on Saturday at about 12:30 p.m. of smoke coming from a recycling yard located near 35th Avenue and Lincoln Street. The recycling yard was later identified as Friedman Waste Control Systems, said Capt. Todd Keller, a spokesman for the Phoenix Fire Department.
A fire engine arrived at the scene and found multiple pallets of cardboard and paper on fire and quickly “balanced” the assignment to a first-alarm fire and started a defensive operation, Keller said.
Due to the amount of materials, fire officials upgraded the fire to a second alarm after more firefighters arrived at the scene. Sector assignments were then made and placed on four sides of the fire for containment.
