What if trees had ratings? What an amazing concept. John Morton, an engineer-scientist-visionary-technician, has been doing canopy studies for years and knows how they are affected by wind. Trees, whether alone or in community, are all influenced by wind and all have a certain “wind rating” to them. When SAR members show up on scene, and …

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, …
The CMC MPD has literally changed the way riggers have thought about “systems”. The lightning rod idea, first envisioned by Kirk Mauthner of Basecamp Innovations, was a work in progress for many years. Once prototypes were completed, the risks heightened! Would teams and personal embrace or reject the concept. Well, the answer was a resounding YES! Sure, it …

The leading authority of professionals discussing technical topics of research dedicated to the rescue industry. Here is a brief summary of early history of the International Technical Rescue Symposium: The germ of the idea for the Symposium actually came from John Dill. One day during a phone conversation, John suggested that what was needed was a …
