(Portland, OR) -- Portland firefighters were busy Saturday afternoon. They responded to a fire in a shed outside of a warehouse in North Portland. As they were finishing the call, a fire was reported in a North Portland duplex. The fire was burning in the walls and difficult to fight. Two residents were treated on the scene for smoke inhalation, along with a dog in the basement. As crews were finishing with that fire, they were called to a man in crisis on the Marquam Bridge. The rope rescue team was on standby, if they were needed. After 10 hours, the man came off the bridge on his own.
