PHOTOS: Emergency departments from Columbia, Ulster and Dutchess counties participated in a mass casualty incident exercise on Saturday. The full-scale drill was performed at Headless Horseman Hayrides and Haunted Attractions in Ulster Park. The mass casualty incident exercise simulated a plane crash and a vehicle entrapment at a campsite in a densely wooded area. The dramatized “victims,” portrayed by community members, included one dead patient, 15 priority one and priority two patients, and four or five walking wounded patients. The participating first responders were tasked with appropriately rescuing, treating and transporting all of the victims using necessary tools like stretchers and the jaws of life. About 125 people, including 14 emergency response departments, participated in the drill, according to Ulster County Chief of Communications Amberly Campbell.
