Blue Mountains Climber's Rescue Group

Report - Practice Day 29/11/00
13 people from a variety of backgrounds attended the day at Narrowneck and a couple of scenarios/systems were practised. Seven of those who attended were on their first prac day with the group.

We did a simple raise of litter with patient and litter attendant on the small cliff at the zig in the access road at Narrowneck. The Larkin Frame was used and the systems were explained and demonstrated to the new members.

We then went to the area above the 100' Slab where we did a lift of two rescuers and a litter with a patient in the litter. The idea of this exerciuse was to try our systems on a less than vertical lift. Two litter attendants made it easier to keep the litter off the cliff face. Some ingenuity was required to set up our "standard systems" in the limited working area on the shale ledge at the top belay of 100' slab. It was considered at one stage to split the systems and have the hauling team and bolt on system above the belay anchors - this was considered to facilitate easier resets (due to loose rocks and sloping ground), but this was deemed unecessary in the end and resets were done remotely using a length of rope.

The general consensus was that wherever possible it will be simpler in most situations to stick with minimal positional variations to our Standard Procedures which are detailed elsewhere on this site.

A 4:1 hauling ratio was used with a team of 5 haulers and was acceptable. Because we were using some existing bolts of unknown origin for part of our main anchor we also added three lines of static rope (equalised) to some trees and boulder anchors on a ledge above the shale ledge.

A moveable redirection (set up with a 3:1 pulley system) was utilised to keep the rescue line and belay line away from a loose rocky slope until the litter was almost at the top. This worked well.

Due to the fact that we are basing our use of a Gri Gri for belaying of rescue line and belay lines on tests that have been done with 200 kg loads we ensured that the total load was less than 200 kg.

The second prac day which was scheduled for Saturday 2/12/00 was cancelled.
