Explosions at NW Portland condo building

July 30, 2013- At 2:19pm Portland Fire & Rescue crews were dispatched to the report of several explosions, fire and smoke coming from an upper floor of a seven story condo building at NW 9th and Hoyt. When crews responded they found that the condo building was under renovation and had scaffolding wrapped in plastic covering one entire side of the building.
Ladder Truck 3 raised it's aerial ladder to the affected section of the building while several additional crews took equipment directly to the seventh floor via an interior stairwell. When they arrived they found that several aerosolized cans of glue had apparently exploded punching holes in the exterior plastic covering the outside of the building. The explosions did not cause extensive damage. Investigators were being called to the scene to look at what may have ignited the cans. No injuries were reported.
