(WASHINGTON) — An improperly extinguished chafing fuel heating canister, canned heat used to keep food and beverages warm, led to a fire on the passenger vessel Spirit of Boston last year while moored at the Commonwealth Pier in Boston Harbor, the National Transportation Safety Board (NTSB) said Tuesday.
As a result of the investigation, the NTSB issued four new safety recommendations and reiterated a safety recommendation to the U.S. Coast Guard.
On March 24, 2023, a fire broke out on Spirit of Boston’s first deck wait station after the scheduled cruise had ended, the vessel had docked and all passengers had departed. NTSB investigators determined the fire started under a plastic glassware rolling cart after an improperly extinguished chafing fuel heating canister was unintentionally dropped by hospitality staff in the area. None of the service workers who were on board at the time of the fire were injured. The fire resulted in $3.1 million in damage to the vessel.
All of the marine crewmembers had departed the vessel before the fire began. Without a properly trained marine crewmember on board with the remaining hospitality staff, the emergency response plan for a fire could not be executed as intended. The NTSB found that the fire could have likely been extinguished before it grew had a marine crewmember been on board at the time.
The NTSB recommended City Cruises US, operator of \Spirit of Boston, require at least one marine crewmember to remain on board its vessels until all non-crew personnel depart the vessel.
Investigators also found City Cruises US lacked documented procedures on how to handle open-flame devices on its vessels. Hospitality staff were verbally instructed on how to handle the heating canisters. NTSB investigators found in some cases the hospitality staff did not consistently extinguish canisters in accordance with the verbal instructions or manufacturer’s guidance.
The NTSB recommended City Cruises US develop procedures for crewmembers and hospitality staff on the proper handling of open-flame devices on board its vessels.
The NTSB also recommended City Cruises US implement a safety management system (SMS) for its fleet. An SMS is a comprehensive, documented system to enhance safety for a company and its vessels and when implemented is an effective tool for safety oversight. Procedures for handling open-flame devices and requirements for crewmembers to be on board would typically be included in an SMS.
The NTSB also reiterated a safety recommendation to the Coast Guard to require all operators of U.S.-flag passenger vessels to implement SMS. The NTSB has advocated for SMS for passenger vessels since 2005, and in 2010, Congress explicitly granted the Coast Guard the authority to require such systems. Progress has been stalled since January 2021 when the Coast Guard took initial steps to address the NTSB’s recommendation.
The NTSB also recommended the Passenger Vessel Association share with its members the circumstances of the Spirit of Boston fire, including the importance of having at least one marine crewmember on board a vessel with non-crew personnel, having procedures for properly handling open-flame devices, and implementing SMS.
