<h1>Introductory chat about expo rigging</h1>
|
|
|
|
<h3>Prerequisites:</h3>
|
|
|
|
<p>This section of the Expo handbook assumes that you are familiar with all
|
|
the usual manoeuvres, such as passing knots, rebelays and deviations,
|
|
changing from abseil to prusik and vice versa. "Familiar" means you can do it
|
|
in the dark with cold hands, with complete confidence in your safety and with
|
|
reasonable efficiency. Choice of ropes is not covered, as by the time you are
|
|
on the expedition it will be too late ! Neither is this guide concerned with
|
|
personal SRT equipment except where the demands of caving in Austria require
|
|
gear in addition to that you would normally use on a typical Yorkshire
|
|
weekend.</p>
|
|
|
|
<p>Self-rescue may also be important in Austria - this should be covered in
|
|
the rescue guide (but isn't - yet). It is recommended that you should
|
|
practice all these techniques somewhere safe and warm - preferably in the UK
|
|
before departure rather than up a tree behind the potato hut in a
|
|
thunderstorm!</p>
|
|
|
|
<h3>Differences from Yorkshire.</h3>
|
|
|
|
<p>This is new exploration, so you cannot rely on belays to have been tested
|
|
by previous generations of cavers. Similarly, loose rocks will not have been
|
|
cleared or dislodged by earlier parties. Natural belays may not be available,
|
|
so you will have to place bolts, rather than look for the shiny P-hangers
|
|
placed by CNCC parties. You won't know in advance how long pitches are going
|
|
to be, so the ropes you have with you may need to be cut or knotted. Party
|
|
size is usually small - everyone needs to be able to make a contribution to
|
|
safe rigging. The first one down may be rigging a new rope to replace a
|
|
damaged one, or one of less than ideal length. The second may have to remove
|
|
the old rope on his descent.</p>
|
|
|
|
<p>Conversely, the caves are deeper, longer and colder than Yorkshire, so
|
|
parties need to move safely and efficiently to avoid exhaustion and exposure.
|
|
Flooding on pitches can be sudden and severe, water very cold, and the
|
|
location of flood inlets not always obvious - rigging for security in flood
|
|
is often critical. Ropes remain in place over several trips, and rock may be
|
|
very sharp - every party must be alert to the danger of abrasion and be
|
|
prepared to rerig if necessary. Finally, rigging points placed on exploration
|
|
may need to be used on expeditions for years to come, so maintenance of bolts
|
|
on the final derigging trips is important.</p>
