  1. TESTS MATERIAL AND CAVE RESCUE TECHNIQUES By Christian Dodelin from France 13° RISS cave rescue in Suisse

  2. The first searchesconcern the stretcher Switzerland (1997) Civière Castin (1976) France • Stretcher • Civière • Camilla • Maca • Nosila • Nosze • Rettungstrage … Great Britain (1997) Romania (1999) Steinberg – Italia (2000)

  3. TSA (1997) Castin (1978) STRETCHERS in France, from (Dr) Castin to the Nest by Petzl We pass by TSA of G. Marbach Nest (2011) The dates are those of pictures

  4. Petzl is doing the material specific for caving, bringing more safety and finding solutions for jammer, descender and pulley. The conditions in the cave are hard with water and mud. • In seventies G. Marbach published • « Techniques Speleo alpines » • He tests and studies the different types • of ropes • Knots • Anchorages… In « Spelunca », national publication in France, we find articles about tests on the new material.

  5. In eighties, in vertical way, we use : • 2 ropes (traction and safety) • The traction was only palan • The deviation pullies were fixed on the rock To extract the pullies we had : to take in charge the stretcher on one rope and keep other free just a short time and take of one pulley. Later we changed the tension on the rope for other pulley. 2 teams at the top for each rope. The leader coordinate the exercise

  6. Before the end of eighties : With the Italian Knot we have releasable pulley We use several knots for anchorage We test new prototype of pulley and agree the system hauling with counterweight We use only one rope to support the stretcher on tyrolean

  7. TESTS by SSF on techniques and materials of cave rescue 1994 – 1996 – 2005 in laboratory of PETZL Establishment, at Crolles, France

  8. We got informations during several minutes from 2 dynamometers in the same time with registration on computer. We could have informations before, during and after a fall We can put the material in the same configuration than in rescue operation We took some used material of 2 ,5, 10, 15 years. (Ropes, carabineers, jammers, pullies, descenders,...) On short distance the condition were unfavourable.

  9. We tested : the three load sharing anchors, eight knot, rabbit knot, stopper knot, Changing the ropes with different diameters , ages, statics or dynamic, dry or wet,… We tested different hauling techniques : Palan, Counterweights, tyrolean and different solutions for the tension of the rope….

  10. We could see the capacities and limits of the different equipments and their possibilities using.

  11. Informatics report is published in French Inside the « cave rescuer’s manual, We have some results and technique indications
