This unit requires the learner to be able plan the work, select and inspect equipment, set up tasks, and erect and/or dismantle the required equipment or structures. Work will often be required to be undertaken with other employees especially tradespersons, bridge and gantry and mobile crane drivers, and doggers. This unit does not cover the slinging of loads which is covered in MEM11004B Undertake dogging, or the skills associated with fabrication and welding of metal structures or components. Where erection, alteration or dismantling of scaffolding is undertaken, the units MEM11001C Erect/dismantle scaffolding and equipment, or MEM11002C Erect/dismantle complex scaffolding and equipment, should be selected. While this unit applies to work covered by licensing requirements, it also includes other manufacturing related skills, such as integrating rigging with welding, fabrication, production, jobbing, maintenance or warehouse operations. This unit is not recognised by regulators for licensing requirements. In order to satisfy licensing requirements, the imported unit CPCCLRG3001A Licence to perform rigging basic level will be required. Band A Unit Weight 4 |

Overview of assessment | A person who demonstrates competency in this unit must be able to undertake rigging to industry and enterprise standards, manufacturer specifications, and in accordance with safety regulations and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person who demonstrates competency in this unit must be able to provide evidence of the ability to: comply with OHS licensing legislation effectively communicate and work safely with others in the work area, including tradespersons, doggers and crane operators effectively conduct risk assessment and management procedures effectively complete the following tasks: inspection of relevant plant and equipment installation of a fall arrest system (static line) use of a safety harness/fall arrest system installation of a safety net installation safety screens work safely at heights erect and dismantle structures, move and correctly locate plant and equipment effectively demonstrate the following knots, bends and hitches: sheet bend becket hitch running bowline double bowline effectively demonstrate the following splices and whippings: eye splice back splice short splice sail makers whipping common whipping west countryman's. |
Context of and specific resources for assessment | Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting. Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace. Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints. Assessment is to comply with the requirements of any relevant standards or operating procedures for basic rigging. Applicants must have access to: personal protective equipment for the purpose of the Performance Assessment appropriate safety equipment in safe condition appropriate rigging equipment, associated equipment associated plant in safe condition as described in the endorsed Assessment Instrument communication equipment (e.g. two-way radios) where applicable appropriate materials as required for safe erection of structures appropriate materials for conducting fibre rope slicing, whipping, knots, bends and hitches. |
Method of assessment | The use of 'simulators' in the assessment of this unit of competency is not acceptable. Assessment may be in conjunction with the assessment of other units of competency. Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge. Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances. |
