Two developments are happening that will make life safer for Hamilton residents when they are sick or injured, officials say. First, the city has purchased its eighth Stryker ambulance cot and related equipment to outfit its latest ambulance that emergency medical services firefighters use to transport patients to hospitals.That equipment costs about $40,000 per ambulance, and all Hamilton’s vehicles now have the equipment.“It can be anywhere from a 600- or 700-pound patient, down to a pediatric child, that when they’re on the cot, very low to the ground, we press a button, and it has a motor on it, and it raises it up to the level that we need to load it into the squad,” said Mark Mignery, Emergency Medical Services coordinator for Hamilton’s fire department.For patients and firefighters, “the big thing is, a reduction in cot-related injuries,” he said.
