    Pardon my asking, but when would this technique be beneficial over the conventional raising system? I just went through RS1 and we did high angle rappel to get to a patient, but picked off onto a raising system. Not trying to be a wise guy, just trying to understand the application.
    BTW here is a pic of me in RS1 training.

    Rope ascending, using the Single Rope Technique is a bit different than most things taught in the fire service. Cave and mountain rescue guys have been using it for years. It gives a single rescuer the ability to move up or down a rope using only the gear on him. This first of all frees up the team to be building systems to move the patient and speeds in the rescue. Second it allows the rescuer on rope the ability to get himself out of trouble. In the hands of a well versed SRT rescuer the system is safe and very efficent. One of the largest principles is the knowledge (abilities, limitations) of the equipment and trusting that equipment.

    SRT is not for a Rescue (General, two-person) Load. For a pick off we still use a dual rope system. Where SRT comes in great is for patient access and litter tending (can rappel or ascend independent of the litter, enabling the litter attendant to get in the best position to negotiate obstacles and transitions).

    Copy that Drew, that makes sense. So a guy on SRT could deliver med supplies and some such.
    Thanks

    Sorry for the delay, been a busy few days.

    We utilize hauling/raising systems, however techs are also required to be able to ascend a line if requried as well as descend. It seems Drew that our system is very similar. though we use a full body harness with chest croll, right hand ascender and a double foot loop.

    I like to keep two of my cows tails long for the harder reaches or for my aid climbing. It will give you more options in the odd spots. Also try replacing the webbing foot loop with a 5mm cord foot loop. It will stow into the hand ascender cleaner and easier to use for a pic off. If you have a perm init upper to your harness such as a Petzl Croll Bod Fast attach one of the cows tails to its D ring. This will give you more space at your main D ring for equipment when transferring ropes, re-belays and rescues. Really all this comes down to how you like to climb and your own body movement. What works for one may be a horrible choice for another. in shape or smaller guys can pull them self up easy, where bigger or older guys may want to use a RADS system.

    Just catching up on the happenings on the forums after not watching them for several weeks.

    Drew hits it on the head. Solid SRT ascending/descending techniques are a key competency for those of us in the mountain rescue realm. In fact we consider it a basic personal skill that you must have before you are cleared to respond on a call. Being able to successfully ascend a fixed rope, pass a knot, switch over to rappel and go back over the knot on rappel is a skill all the trainees demonstrate. This is all done with a ~30 lb pack in the final check off over about ~75-90 feet of free hanging rope. Regular team members also demonstrate proficiency in ascending/descending about every 15 months (the timing varies a bit).

    Do we use the skills frequently? Not really, but they are part of a skill set that can often become important in situations with difficult access. We have used it in situations where the initial rescue is a climbing situation (dynamic rope) where the leader will make access using traditional lead climbing techniques, fix the rope and begin providing care, etc. while other rescuers jug the fixed line. When traveling on glaciers it is also expected that members of a rope team will be able to self rescue in the event of a crevasse fall.

    My basic set-up is based on Purcell prusiks that are always on my harness and ready to go. A basic prusik-based system is usually OK unless we're doing a really long ascent and then ascenders (I use Petzls) are nice. As Fairfield noted - having a system that is safe and works for you is key.

    I will say that the cavers on the team can climb a rope like they were born to it. If you are carrying a few too many pounds in the mid-section, ascending a rope will quickly remind you why every pound matters...

    You talking about me? Yep, I always say some people are better as the rescuer while others make exellent anchors. I will play around with some of those suggestions.
