December 12, 2017 23:10This evening at 6:43pm fire crews were dispatched to the 6100 block of SE 111th Ave. On arrival, responders found smoke in the industrial park and further investigation revealed a fire in one of the metal clad buildings. As crews worked to get hose lines to the seat of the fire, the fire burned through the roof of the building. At 6:57pm the incident commander called a second alarm to get additional resources. During this incident, several challenges arose for firefighters, the first was when a fire hydrant located near the fire building failed to operate. Fire crews had to back track and connect to a different hydrant located outside the industrial park and stretch hose lines approximately 500 feet to the area of the fire building. The second challenge occurred when a large communication line burned through and dropped to the ground. At fire scenes, all downed wires are treated as live power lines until the power company can confirm they're de-energized and safe.
