7 .0 Harness system A comfortable work positioning harness is required for AS rope suspension work. Prolonged suspension can cause compression syndrome (also known as suspension trauma). If prolonged suspension work is anticipated, a bosuns chair (swing seat) will be required. Some harnesses have an inbuilt hard seat but in most cases, a separate bosuns chair is used.. Harness is selected and inspected for faults. Harness meets relevant standards (eg AS 9. or EN ). Fit & adjust harness in accordance with manufacturers instructions. Faulty harnesses are rejected and isolated from use out of service tag is attached. Harness system is suitable for type of work undertaken. Bosuns chair (swing seat) is used to avoid effects of suspension trauma (where relevant).0 Lanyard. Lanyards may be used to aid in traversing under or within certain structures eg, under roofs, under bridge spans, off-shore platforms etc.. Double hook lanyards are preferable since they allow a point of attachment to be maintained at all times while moving.. Check and ensure lanyard is fit for use and meets relevant standards eg [ ] AS 9. or EN [ ] Improvised (no standards mark). Inspect lanyard to ensure fitness for use [ ] within past months (refer AS 9. clause 9..). Use a double hook lanyard [ ] Maintain one point of contact to anchorage point at all times during mobility at height. Use lanyard in accordance with manufacturers recommendations [ ] Avoid short circuiting lanyards (refer AS 9. clause.. a iii). Attach lanyard to appropriate osition on harness [ ] Front attachment (preferred option). Check connector compatibility [ ] Lanyard connector is compatible with harness [ ] Risk of misalignment is minimised or avoided [ ] Resistance to cyclic loading. Lanyard is used in a way that does not create a trip or snag hazard while climbing/moving at height. Stitched double lanyards are checked to ensure no potential failure point exists (eg splitting down the middle).9 Integrate a custom made double lanyard into harness system Checklist AS twin rope access VER. 0/July/009 Copyright PACI Page of

8 SKILL.0 Anchor/belay systems (assessed over at least occasions within a wider scenario context eg as part of a work procedure, a hauling procedure and a lowering procedure) Note: Assessment is contextualised to suit the trainees workplace needs. Assessment will generally be work oriented for example not all trainees will use or have need of proprietary frames, clamping devices or other exotic anchor systems.. Selected knots used within the anchor system are appropriate for the type of load profile / application intended. Knots are recognisable in shape and form steps are taken to create compact and symmetrical knot. Identify, select and use existing structural anchor points in the context of the workplace. Identify, select and use permanently installed rope access anchorages where they exist*. Select & use locking carabiners design limits are not exceeded. Accurately position and align anchor system to optimise for intended trajectory of forces [ ] rope trajectory must be perpendicular with respect to edge. Link individual anchor points to equalise and distribute forces within the anchor system. Completed anchor system meets the requirements of AS and AS 9..9 Backup safety rope is capable of sustaining the anticipated shock loading in the event of main work rope failure.0 Provide a safety belay for a worker. Optional: Permanent anchor points are installed where necessary to enable rope access work to be undertaken.0 Rigging (assessed over at least occasions within a wider scenario context eg as part of a work procedure, a hauling procedure and a lowering procedure) Note: Assessment is contextualised to suit the trainees workplace needs. Assessment will generally be work oriented for example not all trainees will use or have need of proprietary frames, clamping devices or other exotic anchor systems.. Use a frame to direct ropes to a new trajectory. Break into loaded ropes to release tension. Rig ropes underneath overhangs or suspended floor levels. Rig a horizontal lifeline traverse/access system Page of Checklist AS twin rope access VER. 0/July/009 Copyright PACI

9 SKILL.0 Diversion systems. Ropes are accurately redirected to a new trajectory using a diversion system. Diversion anchor points are capable of sustaining the operational load. Housekeeping is maintained with ropes and equipment used to create diversions - trip hazards are avoided or minimised. The effect of rope stretch is determined and adjustments are made to the diversion system to ensure accurate trajectories -long diversions using rope will be subject to significant stretch. Rope alignment with respect to the edge is perpendicular (90 degrees) to avoid risk of pendulum effect or sudden load shift.0 Rope handling skills. Ropes form a fundamental component of all AS rope suspension systems. Safe work practices begins with effective rope handling skills. Check rope to ensure fitness for use [ ] Use tactile means to feel for damage [ ] Use visual checking to observe anomalies. Coil and uncoil a rope using an alternating lay. Manage ropes to avoid entanglements during climbing activities. Use rope bags to maintain housekeeping practices ropes are fed sequentially into rope storage bags to ensure unhindered deployment. Ropes are transported and/or stored in a way that promotes longevity and ease of use. Steps are taken to protect rope from damage where ever contact with edges or abrasive surfaces exists Checklist AS twin rope access VER. 0/July/009 Copyright PACI Page 9 of

10 SKILL 9.0 Abseil access skills 9. Check all clear below before deploying ropes ensure rope deployment cannot cause harm or interference to anything or anyone. 9. Deploy a rope for access purposes stopper knot must be tied in end must deploy tangle free technique must be suited to current situation (eg strong wind gusts) 9. Descend with a rope bag ropes progressively feeds out during descent 9. Perform personal safety checks prior to initiating abseil descent (eg using ABCDE method) 9. Perform abseil descent with bosuns chair (ie swing seat) 9. Configure and descend with an selflocking device (eg SRT No Worries, Petzl ID, etc) [ ] single brake device [ ] double brake device (preferred design) 9. Install a fall-arrest device to on a backup safety rope [ ] manual device (eg Petzl Shunt) [ ] automatic device (eg Petzl ASAP) 9. Operate a fall-arrest device with one hand during descent [ ] do not allow to fall below level of waist line 9.9 Maintain balance, speed control & situational awareness throughout the descent 9.0 Descend in a straight line path relative to anchor system and edge (avoid diagonal descent/pendulum effect) 9. Negotiate obstacles and/or uneven surfaces without losing balance and control [ ] no damage caused to any structure during descent 9. Descend to a target work position then stop maintain position without further slippage or loss of height 9. Descend through wet/dry rope transitions without losing control (optional) 9. spare Page 0 of Checklist AS twin rope access VER. 0/July/009 Copyright PACI

11 SKILL 0.0 Mobility skills 0. The ability to climb up and down a fixed rope is a fundamental skill in AS rope access work 0.

12 SKILL.0 Patient rescue skills. Patient extraction must completed within minutes (measured from moment of contact to moment descent begins). Patient must simulate unconsciousness no assistance or advice given Initial approach to patient. Identify a suitable access route to reach the patient. Install and accurately position a solid & reliable anchor system to enable initial patient access and extrication. Assess the nature of the emergency and respond appropriately take charge if no one more experienced on site Extraction phase. Extract an unconscious patient from a suspended position [ ] patient must not assist [ ] perform an accompanied descent. Shield victim from further injury or harm during abseil descent. Maintain balance and speed control during descent with patient adequate friction must be achieved to cope with added weight of patient. Complete extraction within minutes [ ] approach time is not included. Accomplish rescue procedure using only resources immediately available on harness or within reach from patients harness -no other access to additional gear Basic first aid.9 Administer basic first aid to comfort and reassure the patient [ ] avoid lying patient down on ground (release of blood volume and toxins in legs).0 Take precautions to maintain patient in upright position maintain open airway during descent. spare.0 Lowering skills (systems and techniques used must be realistic and relevant to the trainees situation). Install and accurately position a solid & reliable anchor system to enable the use of a lowering system. Positioning of system will facilitate visual contact and communication with worker. Ropes are managed to ensure free flow through the belay system -no entanglements or unexpected knots. Lower a rope access worker to a target work position. spare Page of Checklist AS twin rope access VER. 0/July/009 Copyright PACI

13 SKILL.0 Mechanical advantage (hauling) skills Assessment activities must be contextualised to suit the trainee s workplace needs. The type and amount of equipment resources used to build M.A. systems must be realistic and relevant. For example, some trainees may use an auto-locking device such as a Petzl ID as their Progress Capture Device (PCD) thereby simplifying the whole process. The use of manufactured pulleys and mechanical ascenders (ie rope grabs) certainly makes the whole system more efficient and easier to use as does edge rollers. PACI philosophy is to find out what is realistic and relevant for the particular trainee and then structure training & assessment activities accordingly if it isn t relevant or realistic then it is pointless to use it! SKILL. Install and accurately position a solid & reliable anchor system to enable the use of a hauling system. Trajectory of hauling system is in alignment relative to edge rope must not bisect edge on a tangent as sideways slippage will occur. Install and accurately position a simple mechanical advantage system (only moving pulley). Hoist a person to a target work position using a mechanical advantage hauling system (eg : assisted hoist). Hoist a load (eg tools or a person) to a target work position using a mechanical advantage hauling system. Increase M.A. while the system is under load modifications to system must be completed within a reasonable time frame. Install an anti-return device (auto-block) to prevent haul load from backsliding during rest intervals anti-return must be effective eg Petzl ID. Implement measures to reduce abrasion damage to ropes during hauling procedures.9 Manage unused/slack rope to avoid entanglement and confusion while hauling ie house keeping skills.0 Theoretical M.A. achieved is consistent with what student originally set out to build (ask student what M.A. s/he thinks Vs what is actually built). Amount & type of resources used to build the M.A. system are consistent with what the student would normally have at the workplace or that which is readily available students must make a reasonable effort to be efficient in the amount of equipment they use. spare KEY = Competent NYC = Not Yet Competent NA = Not assessed Note: This assessment instrument must be held on file for at least 0 years.
