Here in nepal we are conducting rescue methods with joint security forces and they are the key responders,front liners or a first responders. Thank you for your techniques n methods to study.
I am concerned that you are loading the belay @ 13:05 and disconnecting your brake rack. At this point, you no longer have a 2 rope system. If a sharp edge cuts that (previously unloaded) belay line, you have no back-up. A releasable prussik needs to be attached to the load line and loaded before disconnecting the brake rack. Then the load is still on the load line, it will release when you start hauling, and keeps your belay as a belay line. A simple step that maintains the integrity of a 2 rope system.
Just so you know, there are single ropes made with different color or markings on each half. These are commonly used in climbing. That may help with the possible confusion your experiencing.
So if you want to rescue, haul and lower casualties you could simply use a ID and ASAP for back. This enabling you to put In mechanical advantage 3:1 without making any changes to your system plus keeping your rigging clean and simple. Your video is very complicated for a simple rescue system.
Or use an MPD and eliminate the disadvantages the I'D brings to the system. This was shown in the video. MPD's are simply the easiest way to rig a rescue system (when weight is not an issue for your gear).
Got too about 3:30 before i stopped it. Knots left in rope over time weaken the strength of the rope and that is a proven fact. Although i enjoyed the rest of video. Stay safe guys!
The Two rope system is the MPD take one leg of the line and the load is taken at the MPD. Where the other leg the load is taken at the the rigging plate. Even though it is one single rope the load is split on each leg of the line in separate points
Horrible! Never hang on one rope during change over. That point of having a two rope system is having a main and a belay in the event of a main line failure.
+Steve Ventura Thanks for the input Steve. Your perspective is a common one in certain rescue circles. Mirrored systems, single rope techniques, Pick offs and other applications that are utilized in many technical circles will often deploy single line techniques during load transfers or other specific situations with different portable and personal redundancies. Progress can be captured and multiple connection points maintained through different rope grabs or progress capture devices. We strive to pull as many versatile concepts and techniques as we can from other groups such as mountaineers and industrial rescue provided the concepts are safe and efficient. Single Rope Techniques are an acceptable practice per NFPA and are often overlooked across much of the country within the fire rescue community. We advocate these techniques with more advanced end users or practitioners with the right rigging and right KSA's. Thanks for weighing in - we appreciate your insight.
The fact that you say that other circles used different systems doesn't deal with the fact that you are not having a back up when you disconnect one of your ropes. If this system is going to fail is most likely due to a rope getting cut while on tension specially under a 2KN load. When you remove the second rope your rescuer is at risk. You are giving good information during most of your video but you can make this transitions safe by adding a simple step. Redundancy on your anchor was well explained at the beginning so I'll choose not to comment much on that. On a real scenario I would want those two systems on different anchors if possible.

Skydiver BC I agree hey did it again around 18:30. their team needs to reassess their technique. has the potential to get someone killed.

Good instruction with multiple aspects of performing your system.

Thank you brother.

Im, still trying to see how this was a two rope system? can someone tell me where the two separate systems are?
The Two rope system is the MPD take one leg of the line and the load is taken at the MPD. Where the other leg the load is taken at the the rigging plate. Even though it is one single rope the load is split on each leg of the line in separate points
So two ropes, one system. Single anchor stap and biener for both lines doesn't add the redundancy factor to well. Thoughts?
Stay safe thank you.

Good video tho
Real sketchy fellas. Some remedial training on two rope systems would help out.
