Investigators have concluded that the devastating fire and explosion at a Maine lumber mill, which claimed the life of a firefighter and left a dozen others injured, was accidental and originated at the base of a silo, authorities announced on Tuesday.
Details of the Incident
The catastrophic event occurred on May 15 at Robbins Lumber in Searsmont, approximately 95 miles northeast of Portland. The deceased firefighter was identified as Andrew Cross, 27, a member of the Morrill Volunteer Fire Department. Among the injured were family members who operate the mill and other emergency responders. The blaze produced towering plumes of black smoke and required the coordinated efforts of hundreds of firefighters from numerous departments to bring under control.
Cause and Mechanism
According to a statement from the Maine State Fire Marshal's Office, the rapid ignition of particulate material within the silo triggered an explosion that lifted the silo from its concrete base, releasing vast quantities of sawdust and other debris. The silo subsequently toppled, and the surrounding area became engulfed in flames. Investigators noted that the facility's fire suppression system, located near the top of the silo, failed to activate because temperatures at that elevation did not reach the activation threshold, given that the fire started at the base.
Investigation Challenges
The investigation faced delays due to high winds, which created hazardous conditions with flying debris and intermittent interruptions to operations. Drone and aerial photography were particularly affected, prolonging scene documentation, according to Maj. Aaron Turcotte, spokesperson for the Maine Department of Public Safety. Investigators from the state fire marshal's office and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives collaborated on the inquiry, which took hours to contain the fire.
Community and Official Response
In honor of Firefighter Cross, Governor Janet Mills ordered flags to be lowered to half-staff. She expressed her condolences, stating, "My heart goes out to the family, friends and colleagues of Andrew Cross. He died a hero." Robbins Lumber, described on its website as a "high-tech lumber manufacturer" family-owned since 1881, expressed devastation. Family spokesperson Christian Halsted noted it was a "hugely devastating day for the family" and confirmed their cooperation with the investigation.
Lumber and wood products remain a cornerstone of Maine's economy. The Maine Forest Products Council reported that the industry contributed over $8 billion to the state's economy in 2024 and supports approximately 29,000 jobs. Investigators plan to return to the facility in the coming months for a more detailed examination.
