FIRST ZOTZ SPELEO-RESCUE
Fifteen cave explorers from various parts of western Mexico gathered in Zapopan
August 14-16, 2009, to learn and practice techniques for rescuing an unconscious
comrade hanging from a rope inside a pit. This first Zotz Rescue Workshop was
held at the home of Canadian geologist Chris Lloyd in Pinar de la Venta, at the
northern edge of the Primavera Forest, and was led by speleologist Sergi Gómez
In this workshop, the challenge was to master techniques that would not require any more equipment than the normal gear cavers carry for SRT.
“Anyone attempting this kind of rescue must be both skillful and fast,”
explained Sergi, “because an unconscious person hanging from a rope can die
of Harness Syndrome in as short a time as six minutes.”
Death from this syndrome comes about because mountaineering harnesses are
designed for people who are moving and most of them interfere with the blood
circulation and breathing of an immobile subject hanging in the air.
One main focus of the workshop was “picking off” the hurt caver, approaching him or her both from below and from above. The aim here is to bring the victim down to the floor of the cave as fast as possible, to prevent Harness Syndrome and to allow first aid to be administered. After that, the victim can be strapped into a litter and safely hauled up and out of the cave.
The problem in picking people off a rope is that the ascender they are
hanging from is loaded with their full weight and can’t easily be released.
Techniques for transferring the victim’s weight from an ascender to a
descender were the principal subjects of the Jalisco workshop and kept
participants busy for two full days...
Systems to accomplish this included The Catalan (maybe French?) Knee Lift
as demonstrated by Sergi as well as the use of a simple mini-Z-pulley rig. In
addition, some cavers tried out an approach described by Matt Oliphant, in which
the victim is attached to the rescuer by a cows tail and lifted by small steps
until his or her Croll can be disconnected. An advantage of this latter approach
is that either a rack or a Stop can be used for the descent.
As for “picking off” from above, the main problem participants ran into was
attaching a descending device to a weighted rope. It was pointed out that a
Z-pulley system could be used to take weight off the rope during attachment,
but the idea was to accomplish the rescue using “ordinary vertical gear...”
Thus, Sergi showed a special way to load a Stop under these circumstances and John Pint tried his darnedest to figure a way to get a rack on that tight rope. These attempts to use a descending device on the loaded rope were not considered 100% safe by everyone and it could be that simply “jumaring down” (for those who still remember what Jumars are) might be the safest way to reach a victim who is not too far below the rope anchor.
"Gimme a break!" Having discovered exactly what it feels like to be a victim in Jorge's seemingly endless rescue, Chava takes time out for a breather.
At present, the Cave Rescue situation in western Mexico is rather grim.
Organizations one might call upon for “a normal rescue” in western Mexico, such
as the fire department (bomberos), Protección Civil, the Red Cross or the
military, have neither the equipment nor the specialized skills needed for
performing this kind of operation and the closest cave-rescue organizations
capable of doing the job are located far away in Mexico City, San Luis Potosí,
and so on. “In other words,” stated Colima fireman Mitch Ventura, “if we want to
be rescued, we must do it ourselves.”
Before experimenting on volunteer “victims,” the workshop participants
practiced rescuing Baggy Bill, a heavy sack filled with rope, but by the end
of the event, all of them had played the role of both victims and rescuers
and had plenty of bruises and sore muscles to show for their efforts.

"No, no, guys, you got it all wrong! Sergi's video says..., Chin! I wish it wasn't all in Catalan!"
Too bad you can't do a computer check during a real rescue.
"See? You can use a rack too!" says John after rescuing 4000 kilos of rope.
Rocio saves Baggy Bill for the 700th time. "Hey, I think I'm starting to get the hang of it."
