Technical rescue refers to those aspects of saving life or property that employ the use of tools an skills that exceed those normally reserved for fire fighting, medical emergency, and rescue. These disciplines include rope rescue, swiftwater rescue, confined space rescue, ski rescue, cave rescue, trench/excavation rescue, and building collapse rescue, among others. In the United States, technical rescues will often have multiple jurisdictions operating together to effect the rescue, and will often use the Incident Command System to manage the incident and resources at scene.
