Londonderry Fire Conducts Hazmat Drill at Stonyfield

Members of Londonderry Fire Department personnel participated in a hazardous materials training exercise at Stonyfield, on Tuesday, Oct. 27, simulating an escalating ammonia leak and the rescue of a downed worker. The training was one of a number conducted throughout the year. The four-hour drill, conducted started at 9 a.m. under the direction of Battalion Chief Jeff Anderson and TJ Norton, focused on emergency response procedures, interagency communications, rescue operations and hazardous materials mitigation. The scenario began with an ammonia release of approximately 25 parts per million that quickly escalated to 300 ppm, leaving a simulated worker down in the facility’s engine room. Stonyfield personnel activated the company’s Emergency Response Plan and notified 911 and American Refrigeration Corp. (ARC). Firefighters established Unified Command with facility personnel and responding agencies to coordinate the response.
