Flames engulfed a North Portland commercial building early this morning, prompting a swift response from Portland Fire & Rescue. The fire, reported at approximately 10:15 am, sent brown smoke billowing from a garage bay door of a 10,000-square-foot structure in the Overlook Neighborhood. The building, which contained an automotive repair shop and a vacant space, was found to have the smoke under significant pressure as firefighters attempted to gain entry, according to the Portland Fire & Rescue.

Upon arrival, fire crews immediately recognized the need for ventilation to combat the dangerous smoke conditions. The initial engine company and Chief Officer, witnessing the intensity of the situation, transitioned to a defensive fire attack and requested a second alarm due to the building's size. This warehouse-style building, with its scant windows, held the fire beneath the roof, necessitating a large hole to be cut for pressure relief and entry, as detailed by Portland Fire & Rescue.

The operation to cut through the roof improved conditions rapidly, allowing firefighters to launch an offensive. With the hole cut, crews finally made their way into the building, where they were located, and extinguished the fire within 30 minutes of their initial response. The report from Portland Fire & Rescue highlighted the efficiency and speed with which the fire was managed and subsequently recalled.

Despite the perilous situation, no injuries have been reported. On scene, firefighters continued their work post-recall, aiding in ventilation and scouring for any remaining hot spots to prevent further flare-ups. As it stands, the cause of the blaze remains a mystery under active investigation by the authorities. "A few crews remained on scene after the recall to assist in ventilating the building and to continue to look for hot spots," confirmed the report from Portland Fire & Rescue.
