The North Haven Fire department provides first responder advance life support (ALS) services by staffing one (1) Paramedic on duty at all times which responds with Rescue 1. This apparatus responds to approximately 2900 call for service a year. The North Haven Fire Department is dispatched simultaneously to all EMS incidents in town in conjunction with a commercial ambulance service. An overwhelming majority of the time, the North Haven Fire department arrives on scene first to provide emergency medical care while awaiting the arrival of an ambulance. Nearly 300 times a year the on-duty Paramedic has to commit to the ambulance in order to continue with patient care due to the severe nature of the incident. Additional or simultaneous calls for service are answered by Engine 1 and Truck 1, also out of headquarters. These apparatus operate as Basic Life Support (BLS) units, with firefighters trained to the emergency Medical Technician (EMT) level.
