The next thing that stands out in my mind is at 0:53 you see a nice shot of the lowering system on your English Reeve, but there is a key safety point missing. On your vertical control lines, coming from the loads pulley there should be 2 prussiks, one going to each side of the load line. In the event of a load line failure on one side the attendant slides the prussiks up and sets them on the load line, catching on the still good side, preventing a fall.

Right at the beginning of the video you see a gentleman running across the screen with a hand ascender attached in to his harness on a haul line. Im assuming that this line is for traversing the load across the distance. The concern here is that he has the hand ascender attached to his harness, where its not a giant concern, it is a potentially dangerous practice to attach your self to the rescue system your using, in the case of a failure he could potentially be pulled down with the load.

Hi Nzcaver, thanks for your response. I will tell you my concerns for safety within this system. Firstly let me say i understand your Moto for Rig for Success, how ever regardless of rigging for success you need to be prepared for the worse case scenario. If we all worked on good wishes there would be many a person alive today that have died where there Plan for the best situation fell thin.
Iv watched this video a few times here are my thoughts.

There seems to be a lot of times when there is personal with only 1 point of connection.. the system praticed here has the potential to be very dangerous.

@idlhdevon - the highline has multiple point anchors, but the rescuers shown here practicing have single point attachments to the highline. This is not "very dangerous." As cavers and cave rescuers, our PERSONAL rigging is almost always Single Rope Technique (one point of attachment). Patient rigging can either be single or a redundant dual system, depending on the situation and team operating procedures. The philosophy is "rig for success" rather than the old "rig for failure." Thanks.
