Range of Variables The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available |
What work procedures are appropriate for this standard? | These may include climbing plans and specifications, location and site plans, manufacturers guidelines, work schedules, treatment plans, emergency rescue procedures, enterprise standard operating procedures (SOP), and OHS procedures. |
What industry specifications for ropes may be applicable to this standard? | Specifications may include type, dynamics, diameter, tensile strength, breaking strain, safe working load (SWL), and melting point. |
What toolsand equipment may be used in climbing operations? | These may include ropes, safety harnesses, ascending and descending devices, ladders, safety equipment (helmets, ear and eye protection, gloves, boots, etc.), pulleys and blocks, shackles and carabines. |
What enterprise OHS policies may be relevant to this standard? | OHS policies may include safe operation and maintenance of machinery and equipment, safe systems for working at heights in trees, safe procedures for working outdoors, appropriate use of personal protective clothing and equipment, correct manual handling techniques, and procedures for calling emergency services. |
In what complex situations may climbers be required to work? | These may include situations made hazardous by tree branches vulnerable to failure under a load, trees affected by decay, disease and/or pests, trees with embedded objects such as wire, nails or spikes, proximity of power lines, adjacent property, or intruding branches. The trees height, size, trunk characteristics, shape and weight distribution of the crown may contribute to making conditions hazardous to a climber or a felling or trimming operation. Inclement weather may also contribute to making working conditions difficult and hazardous. |
What personal protective (PPE) and safety equipment may be used to when climbing trees? | Equipment may include boots, overalls, gloves, hard hats/helmets, ear and eye protection, safety harnesses, ropes, sun hats and sunscreen lotion. |
What techniques are used to access trees in complex situations? | Techniques may include setting false anchor points, footlocking and using climbing spikes. |
