New Bedford Fire Department Responds to Tier 2 Ammonia Leak
At approximately 4:21 a.m., the New Bedford Fire Department received an alarm notification from a fire alarm monitoring company reporting ammonia system alarms at 12 Fish Island, a waterfront cold-storage facility with numerous potential hazards.
Engine 1, Engine 6, Ladder 1, Unit 2, Hazmat 1, Inspector 2, and Chief 2 responded. Upon arrival, Unit 2 detected positive readings for ammonia and requested assistance from the Massachusetts State Hazmat Team, EMS, the Department of Environmental Protection, the Department of Public Health, and the Providence Canteen.
The incident was quickly escalated to a Tier 2 active ammonia leak, and the facility was evacuated. Three employees were inside the structure at the time.
The Massachusetts State Hazmat Team made multiple entries into the building to locate and secure the leak, with assistance from New Bedford Fire Department crews. Firefighters deployed a hose line and multiple fans to support decontamination and ventilation operations while maintaining a Rapid Intervention Team.
New Bedford firefighters also assisted by providing access to areas of the facility, including the roof and other difficult-to-access locations.
There were no injuries reported.
This incident highlights the importance of coordinated response between local, state, and environmental agencies when dealing with hazardous materials emergencies. We thank all responding personnel and agencies for their professionalism, teamwork, and dedication in safely managing this incident.
