Mainline Rescue Systems: Pre-plan the Working Line

Pre-plan the Working Line All too often, teams rig their haul system with the progress capture device (the ratchet) at a directional anchor located in front of the mechanical advantage system.  This ratchet position is most often due to the lack of pre-planning the layout of the working/haul line system. Usually, the rigger will build …

Leading From Knowledge and Perception

Ice Breaker: The goal of “thinking beyond our thoughts” or metacognitive strategies is to help us become comfortable with developing strategy. Why is this so vitally important to us as humans, riggers, and rescuers? We as people, especially in today’s world, tend to take the easy way out and “believe” what we are told and this …

Using the Fast Fours for Confined Space Rescue and Fallen Worker Rescue/Recovery

What has happened… a worker has fallen from his working platform. The worker condition is good enough where he is able to assist in his own recovery and rescue. This video was developed over a span of time where Rich took to heart, the process of confined space rescue, fallen worker rescue and simply using …

Why “cross pollination” (hybridization) is crucial in rope rescue and rigging.

So what exactly is “cross pollination”?  Well… glad you asked.  Most understand this term through botany channels and while this is true, it is also true that cross pollination is “a sharing or interchange of knowledge, ideas, etc.” and it is through this that I want to make a statement.  “Without cross pollination, civilization as …

T Method Applied To Mechanical Advantage Systems Using Rope Grabs

T Method Applied To Mechanical Advantage Systems Using Rope Grabs. Calculating mechanical advantage: the T-system 1. Assume continuous strands of rope have the same amount of tension. If we start at the point where effort is applied and assume that we apply one unit of tension (1T) then we can assume that the tension along …
