Rope rescue: ASAP performance on a taut rope

Warnings

  • Read the technical notice before viewing the following techniques.
  • It is important to fully understand the information provided in the technical notice before using this complementary information
  • Mastering these techniques requires training.
  • Consult a professional before attempting to perform these techniques on your own.

When a victim is suspended on their work rope with an ASAP on their safety rope, certain rescue techniques allow the rescuer to use the victim's ropes for access. The rescuer installs his progression system on the victim's safety rope and his ASAP on the victim's work rope.

In case of mishandling, anchor failure, or rope failure during the victim access phase, one of the team members may fall. His ASAP must then stop the fall on a taut rope.

Accessing the victim from above.

The rescuer's ASAP is installed on the victim's work rope (rope 1). In case the rescuer descends too fast, or if rope 2 breaks, the rescuer's ASAP should lock onto rope 1, which is held taut by the victim's weight.

Access from above

Accessing the victim from below.

The rescuer's progression system is installed on the victim's safety rope (rope 2).

In case rope 1 breaks, the victim's ASAP should lock onto rope 2, which is held taut by the rescuer's weight.

Access from below

Note: in both situations, a secondary accident will complicate any rescue operations. Maximum precautions must be taken to avoid any anchor or rope failure while rescuing a team member. If the team member's ropes are unreliable, other ropes must be installed.

TESTS:

Tests carried out have shown that the ASAP works normally on a taut rope, without increasing the impact force and without damaging the rope.

Test 1:

100 kg mass, connected to the ASAP by an OK TRIACT without an energy absorber.

10.5 mm PARALLEL rope, tensioned by a 100 kg mass.

Start of the fall: ASAP at 1 m from the anchor, mass above the ASAP (fall of 2 times the length of the connector)

Test 1
Rope intact

Result:

Rope intact / 3.2 kN impact force / 50 mm ASAP displacement

Test 2:

100 kg mass, connected to the ASAP by an OK TRIACT + ABSORBICA + VULCAN

10.5 mm PARALLEL rope, tensioned by a 100 kg mass.

Start of the fall: ASAP at 1 m from the anchor, mass above the ASAP (fall of 2 times the length of the energy absorber + connectors)

Test 2
Rope intact

Result:

Rope intact (sheath very lightly marked) / 3.9 kN impact force / 50 mm ASAP displacement / 200 mm ABSORBICA tearing
