ROPE RESCUE SYSTEMS BELAY SYSTEMS
ROPE RESCUE SYSTEMS BELAY DEFINITIONS 1. Belay – to provide protection against a fall by handling a tensionless rope (belay rope) in such a manner that it may be taken in or let out as another person(s) climbs, rappels, or ascends a fixed rope or is raised, lowered or transported, yet be secure to hold this load in case of failure of the main support. 2. Self Belay – to provide protection against a fall by the person(s) 3. Conditional Belay – to provide protection against a fall by using a needing the protection moving their adjustable connection point along a fixed rope, that remains without tension until the fall, as they climb, rappel or ascend a different fixed, or are raised, lowered or transported, by a separate rope, that is already under tension from all or part of the load, to hold the load should a failure occur in some other part of the system. (RFR BD-1 1996 adapted from BCCTR Notes prepared by Arnor Larson)
ROPE RESCUE SYSTEMS BELAY DEFINITIONS 4. Conditional Self Belay – to provide protection against a fall 5. Auto Belay – (“Deadman” Belay) a self activating belay that 6. Pseudo Belay – a belay that will not work; that is pretend, by the use of a conditional belay that is managed by the person(s) needing the protection. does not require a positive action to engage it. The term auto can be applied to any of the 4 types of belay listed above when it is appropriate. counterfeit or false. The term pseudo can be applied to any of the 4 types of belay listed above when it is appropriate. (RFR BD-1 1996 adapted from BCCTR Notes prepared by Arnor Larson)
ROPE RESCUE SYSTEMS TANDEM PRUSSIK BELAY SYSTEMS
ROPE RESCUE SYSTEMS BELAY SYSTEMS • Rescue Systems Testing The B. C. Council of Technical Rescue (BCCTR) started testing of systems in 1982. • The BCCTR has the following minimum standard: with a 200 kg mass (two persons + equipment = load) tied to 3 meters of rope, the belay system must be able to withstand a 1 meter drop of the load and stop it in less than 1 meter of additional travel and with less than 15 KN of force (while retaining 80% of system strength. (copyright © 1990 – Arnor Larson)
ROPE RESCUE SYSTEMS BELAY SYSTEMS • It is of great concern that a number of systems in present use cannot manage this bare minimum! • To date the only belay system tested successfully in accordance with the BCCTR standard is the Tandem Prusik Belay. (copyright © 1990 – Arnor Larson)
ROPE RESCUE SYSTEMS BELAY SYSTEMS • To date no Gibbs, rescuesender, or other mechanical belay device tested has met the BCCTR 1 meter minimum. • Note: since 1990 the only mechanical belay device that has meet the BCCTR standard is the 540° Belay (copyright © 1990 – Arnor Larson)

ROPE RESCUE SYSTEMS EDGE TENDER
ROPE RESCUE SYSTEMS EDGE TENDER 1. Edge Tender Safety – Edge tender has independent anchor (may share a bomber anchor point, but may not attach to system anchors) – Edge tender is tied into an adjustable tether before approaching the edge – Clears loose rocks and tripping hazards from the edge
ROPE RESCUE SYSTEMS EDGE TENDER 2. System Safety – Places ropes on appropriate edge protection – Assures ropes remain on edge protection.
ROPE RESCUE SYSTEMS EDGE TENDER 1. Attendant Safety – Assist attendant and stokes over the edge
ROPE RESCUE SYSTEMS EDGE TENDER 1. Attendant Safety – Weighting the system before going over the edge removes slack and stretch in the main line. 20’ of rope in operation, with a 2% stretch, will result in 3”-6” of sudden movement if the system is not weighted. • • • Tightening of knots Stretch of rope Rigging extension
ROPE RESCUE SYSTEMS EDGE TENDER – As attendant goes over the edge, the “Lower slow” used in approaching the edge should be slowed even more, – The upper body of the attendant is rotating through an arc. For a brief period, the feet are neither moving back nor moving down.
ROPE RESCUE SYSTEMS EDGE TENDER – Communicates with, and for, the attendant at the edge. Halts system 1 meter from edge for tensioning Edge Tender “STOP!” Ops Leader “Why Stop? ” “Attendant tension the system” <attendant weights system> “Lower slow” “Lowering slow” “Attendant at the edge” “Lower slow” <attendant rotates over edge>
ROPE RESCUE SYSTEMS EDGE TENDER – Provides voice communication between Ops Leader and Attendant to relay changes in speed control – Observes the path of the rope to detect additional rope hazards requiring edge pro

ROPE RESCUE SYSTEMS LOWERING SYSTEMS Kurt Bandilla
ROPE RESCUE SYSTEMS LOWERING SYSTEMS
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Brake Bar Rack – Standard for MRT Lowering systems – A U-Shaped frame – A series of bars – Hyper-bar • Tie Off • Add Friction
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Advantages – Allows friction to be varied, even when loaded – Does not twist rope – Can be easily attached to a rope without detaching from anchor – Can use two ropes – Can use varying sized ropes
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Disadvantages – Bulkier and heavier than other lowering devices – May take slightly longer to load the rope
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Other Considerations – Eye may be oriented 90 o – Rope should pass over the loading groove – Welded eye on the frame is rated over 10, 000 lbs. (44 k. N)
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Other Considerations – Bars may be aluminum or steel – Bars come in a variety of shapes – Only use bars designed for your brake bar – Assure you are using a rescue rated brake bar rack
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Set up your anchor or check to assure that an established anchor is adequate • Equipment that will be used later is attached to the anchor plate
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Tie a figure-8 in the end of the rope and clip to the large hole in the anchor plate with a locking carabiner • This assures the rope does not leave unexpectedly if someone pulls the rope before the system is complete
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • To have the lowering system pass the whistle test, tie an 8 mm prusik hitch to the anchor plate with a load release hitch • The disadvantage is having to mind the prusik
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Rig the rope through the brake bar • Advise Ops Leader, “Main Line Ready to Lower!” • Lock off the Brake Bar if it is to be unattended for any length of time
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Tying Off
ROPE RESCUE SYSTEMS LOWERING SYSTEMS • Brake Bar tie-off using the hyper-bar • Demonstrate Tie-off of Brake Bar without hyper-bars
ROPE RESCUE SYSTEMS MECHANICAL ADVANTAGE REVIEW
ROPE RESCUE SYSTEMS • Gravity = Weight – 1 k. N = 224. 81 lbf – 1 Person ≈ 1 k. N – 2 Person ≈ 2 k. N – 3 Person ≈ 3 k. N
ROPE RESCUE SYSTEMS – The average rescuer can hold or apply a. 2 k. N force with one hand (≈ 45 lbs) – The average rescuer can hold or apply a. 4 k. N force with two hands (≈ 90 lbs) – Hauling an rope ‘hand-overhand’ is applying a force of 45 -50 lbs
ROPE RESCUE SYSTEMS • Impulse (force of impact) – The average reaction time to a failure or rope movement is 1 sec – In 1 sec a 1 k. N load will travel 16 feet – The 1 k. N load will be traveling 21. 8 mph – A fall of 16 ft on 85 ft of static rope will result in an impact force of 13. 5 k. N (3035 lbs)
ROPE RESCUE SYSTEMS BELAY INCOMPETENCE CRITERIA • Falls on a static rope – Fatal falls on a static belay line would be the result of belayers not paying attention – What happens at 12 k. N?
ROPE RESCUE SYSTEMS Pulley Types: • Fixed pulley – Provides change of direction ONLY
ROPE RESCUE SYSTEMS Pulley Types: • Movable pulley – Adds Mechanical Advantage
ROPE RESCUE SYSTEMS • The longest distance a pulley system can be stretched, the distance from the anchored pulley to the moving pulley, is called the stroke. • The longer the stroke, the more useful the MA system.
ROPE RESCUE SYSTEMS • If the terminal end of a haul line is attached to the anchor, the simple pulley system will be EVEN • 2: 1, 4: 1, 6: 1, 248: 1
ROPE RESCUE SYSTEMS • If the terminal end of a haul line is attached to the anchor, the simple pulley system will be EVEN • 1: 1, 3: 1, 5: 1, 115: 1
ROPE RESCUE SYSTEMS RAISING SYSTEMS Clark Wurzberger
ROPE RESCUE SYSTEMS RAISING SYSTEMS • Hauling without the aid of a system is a Mechanical Advantage of 1: 1 • Also known as the Armstrong Method
ROPE RESCUE SYSTEMS RAISING SYSTEMS • Our simplest system is the Simple 2: 1 Mechanical Advantage • Components are: – Rope – One pulley
ROPE RESCUE SYSTEMS RAISING SYSTEMS • Our basic haul system is the simple 3: 1 Mechanical Advantage • Components are: – Rope – Two (2) pulleys – One (1) rope grab
ROPE RESCUE SYSTEMS RAISING SYSTEMS • With the addition of a single pulley, the 3: 1 is converted to a 5: 1 Mechanical Advantage • Components are: – Rope – Four (4) pulleys
ROPE RESCUE SYSTEMS RAISING SYSTEMS • Piggybacking the simple 2: 1 onto the simple 3: 1 provides a compound 6: 1 Mechanical Advantage
ROPE RESCUE SYSTEMS RAISING SYSTEMS Setting and Resetting the System Once the haul team has collapsed the system, it must be reset to its maximum length so hauling can continue Haul Prusik reaches Progress Capture Device (PCD) Main Line Lead: “Stop. . . Resetting” PCD is set by Haul Team Member setting PCD: “Set” Haul Team Member fully extends the throw of the system Haul Team Member extending system: “Reset” OPS: “Raise Slow” Do NOT use the words “Reset” or “Resetting” while actually extending the system. Only use the word “Reset” when the task is fully completed.
ROPE RESCUE SYSTEMS RAISING SYSTEMS • Piggybacking the simple 2: 1 onto the simple 5: 1 provides a compound 10: 1 Mechanical Advantage
