Investigation Unable to Pinpoint Definitive Cause of Haskell's Port Fire, Cigarette Remains Possibility

A recent review of the devastating fire at 1 Water Street highlights the absence of critical fire detection systems and ongoing challenges in pinpointing the exact ignition source.

Published Oct 3, 2026

A comprehensive review of the devastating fire that swept through Haskell's Port of Excelsior on May 6, 2026, has concluded that while investigators cannot definitively pinpoint the exact cause, an improperly disposed cigarette remains a leading possibility. The "Fire Cause and Origin Investigation" presented during a recent City Council meeting also underscored a significant safety concern: the complete absence of fire detection and suppression systems at the 1 Water Street property.

The Hennepin County Fire Investigation Team, tasked with determining how the fire started, detailed its findings, emphasizing the challenges inherent in forensic analysis after such an extensive blaze. Their report noted that despite thorough examination, they were unable to conclusively rule out an improperly discarded cigarette as the ignition source. This finding leaves a critical gap in understanding the full circumstances leading to the incident's ignition.

Determining the definitive cause of a fire of this magnitude is always a complex endeavor. While we have narrowed down possibilities, certain indicators point to a potential human element, though without concrete evidence, it remains a strong possibility rather than a certainty.

Of particular concern highlighted by the investigation was the revelation regarding Haskell's Port of Excelsior's lack of internal safety infrastructure. Officials pointed to the absence of crucial fire detection and suppression systems as a critical factor that could have allowed the fire to spread unchecked in its early stages.

The absence of crucial fire detection and suppression systems at Haskell's Port of Excelsior was identified as a major safety concern during our review. These systems are vital for early warning and initial containment, which can make all the difference in preventing minor incidents from becoming catastrophic events.

Beyond the origin, the investigation also touched upon the incident's progression and the response. The structural integrity of the building became a critical factor during firefighting efforts. Firefighters were alerted to the failure of structural roof joists by Thermal Imaging Cameras, a crucial early warning that enabled personnel to evacuate safely and prevented potential casualties. This timely detection underscored the importance of advanced tools in mitigating risks for first responders.

Interagency Response and Future Improvements

The After Action Review, presented alongside the cause and origin findings, praised the successful interagency coordination between 13 different agencies involved in battling the blaze. Despite the immense scale of the incident, the collaborative efforts were noted as highly effective in managing the crisis. However, the review also identified operational areas for improvement, particularly highlighting the need for enhanced rehab usage for firefighters on scene and clearer radio communications for structural updates during large-scale incidents.

While the collaborative response was commendable, every major incident presents an opportunity for learning. Our goal is to continually refine our emergency protocols, ensuring our responders have the best possible support and communication tools to safely and effectively manage future emergencies. The insights from this investigation are invaluable for ongoing training and policy adjustments.
