Ludington, MI (March 3, 2026) – A contractor was injured on Monday morning, March 2, after a carbon dioxide fire-suppression system accidentally discharged aboard a tugboat docked in Ludington Harbor.
Emergency units responded around 11:30 a.m. after the incident was reported aboard the tugboat Undaunted, which is docked for the winter in Ludington.
According to initial information, the contractor was performing maintenance on the vessel’s carbon dioxide fire suppression system when the system unexpectedly activated. The sudden release of the gas caused the worker to suffer injuries.
Crew members and staff present on the vessel quickly provided first aid and began life-saving measures while waiting for emergency responders to arrive.
The injured contractor was transported to a nearby hospital for treatment, but authorities have not released details about the person’s condition.
The tugboat is owned by Interlake Logistics Solutions, a division of the Interlake Steamship Company, which operates cargo vessels throughout the Great Lakes.
Authorities continue to investigate the cause of the incident, and more details will be released as soon as they are provided.
Our thoughts are with the injured worker as they receive medical care.
How Carbon Dioxide Fire Suppression Systems Work on Ships
Many ships and tugboats are equipped with carbon dioxide fire suppression systems designed to quickly control fires in engine rooms and other enclosed spaces. These systems release large amounts of CO2 gas, which reduces oxygen levels and prevents flames from spreading.
Because the gas displaces oxygen, these systems can be dangerous if they activate while people are nearby. Crew members and technicians working on the equipment must follow strict procedures before performing maintenance. This often includes isolating the system and confirming that the release mechanisms are disabled.
Accidental discharges can occur during inspections, repairs, or testing if safety steps are missed or equipment malfunctions. Maritime safety practices often require warning systems, alarms, and evacuation procedures to reduce the risk to workers when these systems are triggered.
