Thinking smart is power. Power is the ability to get things done with an element of Authority. Authority carries with it a mantle of Responsibility. Responsibility carries with it the need for planning and expected outcomes. The following is quick mini look at developing a mindset of “multiplicity”. Manpower is expensive. Equipment is relatively cheap …

Dynamic Directionals (a type of offset) are useful in adjusting the main line and belay from above the rescue page or in some cases, from across a gap or chasm. The use of this system usually requires a fair amount of horsepower, at least a mechanical advantage of 6:1 or 9:1, but not always. As …

Skate blocks are aerial track systems that are considered by many to be simpler to rig than a traditional highline system… and often much more effective. Enjoy this training video from Coming Soon release of Confined Space Rescue from Ronin Safety and Rescue. There are numerous variations to the “skate block” Often a skate block …

Hey all Dynamic Directional Anchors are useful in adjusting the mainline and the belay line from above the rescue package, or in some cases, from across a gap or chasm. For short gaps, a minor dynamic directional could be your ticket for success. A belay for the point of horizontal influence may not be required …
By: Jason Ilowite When we reach way back in our memory banks to when we were new drivers, I would venture to say most of us dreamed about rolling down the road in a nice new luxury or sports car some day. We all, however, recognized the importance of learning on the older model, that …
In Track Lines and Guiding Lines: Forces Based on Point Loads in a Catenary, Stephen Attaway says, “The scope of this paper is limited to providing a better understanding of how to predict sag, tension, forces, and possible hazards.” This research was originally presented at the International Technical Rescue Symposium (ITRS) in November of 2013, …
Thomas Evans re-presented an incredibly interesting topic: The Diminishing Loop Counterbalance. As with most ITRS presentations, this 2013 presentation had its skeptics as well as supporters. And too, as with most ITRS presentations, controversy was felt. This how our industry grows, expands, and becomes a living document. While this type of rescue isn’t for everyone, …

In our last few blogs, the theme was efficiency in purchasing gear. This is still the case. As more and more gear outlets are moving towards less phone time and a heavier reliance on the site doing the work, this either makes things more difficult or harder. Many are completely at home at ordering gear …

Moving Beyond 10:1 Static System Saftey Factor Moving Beyond 10:1 SSSF Introducing Force Limiting Systems and Managing the Right Risk at the Right Time ITRS 2014 By: Kirk Mauthner, British Columbia, Canada, kirk.mauthner@gmail.com Abstract: Most rope rescuers are aware or familiar with the concept of applying a safety factor – such as 10:1 – to …
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 this single strand of rope will be the same throughout. …
