Northern Door firefighters received an opportunity to work through some of the new challenges presented when rescuing motorists from newer cars. The construction of cars has changed drastically over the last few years with new metals and technology being instituted in the process. Firefighters from Sister Bay/Liberty Grove, Gibraltar, Egg Harbor, and Baileys Harbor got a chance to practice on these cars, providing invaluable experience according to Sister Bay/Liberty Grove Fire Chief Chris Hecht. Hecht says even trainers are learning on the job as new construction techniques get introduced. An additional training on the crash-tested New Vehicle Technology cars donated by Volvo will most likely take place in 2018.
