Every anchor gets rigged for a number. Usually that number is the load: the weight of the patient, the litter, and the attendant hanging on the mainline. Build the anchor strong enough to hold that load with a healthy safety factor, and the job feels done. The problem is that the anchor doesn’t only hold

A rescue package must travel across a gap between two elevated positions, and the clearance beneath the crossing is limited. The crew has to move the load while managing the forces placed on the system that supports it. A two-rope offset, a highline and a two-rope dynamic directional can all accomplish that movement, but each

A rope rescue technician may remember how to assemble a familiar system but struggle to predict how it will behave when the load, geometry, or operating conditions change. This is an important consequence of skill fade because procedural knowledge and technical reasoning do not necessarily deteriorate at the same rate. Understanding rope rescue system behavior
