Puget Sound Fire says crews responded to reports of a house fire in the 23400 block of 116th Ave SE, near Fire Station 74.
The first engine to arrive knocked down the fire from the outside before making entry.
While firefighters were conducting a search of the first floor, two of them fell through a hole in the floor that had been partially covered by the residents.
One of the firefighters was able to free himself, but the other was suspended upside down in wires from the ceiling. Other firefighters that were inside the house – plus an additional crew from outside – were used to free him. He was brought outside in less than 5 minutes with no injuries.
