Authorities announced Tuesday that the deadly blaze and blast at a Maine lumber facility that claimed a firefighter’s life and wounded twelve others was unintentional and began at the bottom of a storage silo.
The May 15 incident at Robbins Lumber in Searsmont resulted in the death of Andrew Cross, 27, from the Morrill Volunteer Fire Department. Those hurt in the incident included family members who operate the lumber facility as well as other emergency personnel. The blaze created massive clouds of dark smoke and necessitated hundreds of firefighters from multiple departments to bring it under control.
Quick ignition of dust particles led to a blast inside the silo that lifted it off its concrete foundation and released substantial amounts of sawdust and other debris, according to a Tuesday statement from the Maine State Fire Marshal’s Office. The storage structure then collapsed and flames spread throughout the surrounding area, officials reported.
The fire marshal’s office indicated that investigators plan to return to the site in upcoming months for a more thorough examination.
“Investigators also determined the facility’s fire suppression system, which was located near the top of the silo, did not activate because temperatures at that elevation did not reach the activation threshold after the fire originated at the base of the silo,” the office’s statement said.
Facilities that process lumber are significant sources of flammable dust. Strong winds during the investigation postponed the release of findings, according to Maj. Aaron Turcotte, a spokesperson for the Maine Department of Public Safety, who spoke last week.
“High winds throughout the day created difficult working conditions on scene, resulting in flying debris and periodic interruptions to investigative operations. Drone operations and aerial photography were particularly challenging due to the wind, causing delays in some scene documentation,” Turcotte said in a statement.
The blast in Searsmont, located approximately 95 miles northeast of Portland, prompted a large-scale emergency response to this remote area of the state. Personnel from the state fire marshal and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives launched an investigation following the explosion and fire, which required several hours to control.
Gov. Janet Mills subsequently directed that state flags be lowered to half-staff last week to honor Cross.
“My heart goes out to the family, friends and colleagues of Andrew Cross,” Mills said. “He died a hero.”
The company’s website characterizes Robbins Lumber as a “high-tech lumber manufacturer” operating since 1881 and owned by the same family for five generations. Christian Halsted, speaking for the family, stated following the fire that it was a “hugely devastating day for the family” and confirmed the family’s cooperation with investigators.
Wood and lumber products represent a vital and longstanding industry in Maine. According to the Maine Forest Products Council, the sector generated over $8 billion for the state’s economy in 2024 and employs approximately 29,000 people.
