The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Relevant compliance documentation may include: | legislative, organisation and site requirements and procedures manufacturer's guidelines and specifications Australian standards code of practice customisation of assessment and delivery environment to sensitively accommodate cultural diversity Aboriginal people and other people from a non English speaking background may have second language issues |
Equipment may include: | collar piping covering devices (e.g. plugs, cones, hessian bags) drill rig (e.g. electric/hydraulic, pneumatic) drilling components (e.g. drill rods, bits, augers, down hole hammer, down hole tools) extra lighting (e.g. flood lights) flags hoses inclinometer lifting and handling equipment long hole extension drills measuring tape oils paint (e.g. spray cans) plates recovery equipment scaling bars signs support vehicles tamping sticks tapes witches hats recommended/required PPE |
