hmmm they do suggest using a topping down strop etc using a back up system on the ground for rescue ops ...
as to help especially if unconcious or a larger build
so i would disagree with you blakes but in a nice way ...
following taken from climbers good guide etc
RESCUE METHOD C
3 person unit only
Diagram
The rescuer climbs to a suitable anchor point above the casualty taking the rescue rope up
with him/her. The rescue rope is passed over a suitable anchor point.
The rescuer descends to the casualty, assesses and makes safe any hazards which
threaten the casualty or would impede the rescue, e.g. chainsaw, other equipment/tools,
tree debris.
The rescuer assesses the casualty's condition making safe where necessary and
administers first aid if appropriate.
The rescuer attaches the casualty to the rescuer's harness to aid descent and prevent
separation of the casualty and rescuer. This may take the form of a short sling connected
by karabiners to both harnesses.
The rescue rope is attached to the casualty's harness.
The groundperson ties a prussic loop on the rescue rope attaching this to a suitable
anchorage (groundperson's harness, vehicle, tree, ground anchor, etc). This must have
sufficient friction to help the rescuer make a controlled descent.
The rescuer transfers the casualty's weight to the new connection, taking up any slack to
prevent the casualty falling any distance then disconnects or severs the casualty's
rope/strop.
The casualty is gently lowered by the groundperson whilst the rescuer guides him/her
through the branches or supports an injured limb.
If the casualty is conscious then the rescuer should be aware that the casualty is in a
position to 'help' during the rescue – this keeps the casualty occupied and aids rescue.
The casualty can be carried away from the tree whilst still attached to the rope, if
assistance is available.
Rescue teams need to practice methods regularly, to be effective in actual emergency
situations.
RESCUE METHOD D
2 or 3 person unit
24
Diagram
The rescuer climbs up to the casualty (using climbing irons and a strop) and with care,
makes a suitable anchor with a suitable topping down strop to which the rescuer’s climbing
system or a separate rescue rope is attached.
The rescuer assesses and makes safe any hazards which threaten the casualty or would
impede the rescue, e.g. chainsaw, other equipment/tools.
The rescuer assesses the casualty's condition making safe where necessary and
administers first aid if appropriate.
The rescuer attaches the casualty to the rescuer's harness as in rescue B or to the rescue
rope as in rescue C.
The casualty’s weight is transferred to the rescue system and the casualty’s spikes and
lanyard/climbing system are disconnected or severed.
The casualty is lowered to the ground by the rescuer or by the rescue rope.
If the casualty is conscious then the rescuer should be aware that the casualty is in a
position to 'help' during the rescue, this keeps the casualty occupied and aids rescue.
Rescue teams need to practice methods regularly, to be effective in actual emergency
situations.
ADDITIONAL ITEMS
3 If the casualty is unconscious or injury prevents him/her assisting the rescuer the gaffs
on his/her climbing irons and/or strop tension can severely hinder release by the
rescuer. In such cases the ground personnel must relieve the weight on the strop
and/or gaffs so that the rescuer can safely release the casualty's strop.
