A Pennsylvania-HART rescue technician (RT) is lowered from a UH-60 Blackhawk to an injured victim. Once on scene, the technician completes an evaluation and determines a course of action. He places a rescue strop around the victim and communicates with the Blackhawk via radio for the hoist hook to be lowered. Once the technician and victim are attached to the hoist hook, the RT signals and they are hoisted to the Blackhawk.
