Not disagreeing with the "every sailor a firefighter", although the current generation ISS astronauts get considerable EMT training, along with other necessary emergency skills. Most astronauts have considerable knowledge of electrical system as well. Were the Hi-SEAS astronauts trained to the same level as a NASA ISS astronaut? Unlikely. Should a future Mars simulation have at least one highly experienced EMT, if not an actual emergency physician? Yes. Should a future Mars simulation have at least one person with considerable experience in electrical engineering, computer science or avionics systems? Yes.
