Elements and Performance Criteria

Stream: Production Plant
Field: Maintenance
Equivalencies: This unit of competence is based on units 1, 2 and 3 class
intermediate rigging of the Worksafe Australia (NOHSC:1006 [1992])
National Competency Standards
Correct size of equipment may be determined by calculating safe working loads using load charts and standard calculation rules
Potential hazards may include overhead services such as steam, gas, water, telephone and power cables, uneven or unstable ground, trees, underground services, buildings and structures, other personnel and environmental influences such as lighting, noise, temperature and wind
Tools and equipment may include spanners, hammers, pinch bars, clamps, pulleys, chain blocks, and pull lifts, winches, jacks, skids, rollers, cradle timbers, chocks and wedges, packers, fish plates and bolts, feeler gauges, turfers and turn buckles
Lifting equipment may include chains, spreader beams, ropes, wire ropes, shackles and eye bolts
Appropriate signals and communication methods may include verbal, hand signals, whistles, hooters, two way radio and lights (all to the relevant Australian standard)
Resources may include cranes, hoists, drawings/plans and personnel
Fixing and anchoring methods may include bolting, wedging, riveting and tying
Intermediate rigging work may include movement of plant and equipment, steel erection, particular hoists, placement of pre-cast concrete, safety nets and static lines, mast climbers, perimeter safety screens and shutters, cantilevered crane loading platforms, slinging and directing of loads, rigging of cranes, conveyors, dredges and excavators, tilt slabs, demotion and dual lifts
Hazards which may affect demolition may include corroded members, impact forces, undermined foundations, hidden voids, unidentified services, hazardous substances and unstable structures
Work completion details may include plant and maintenance records, job cards, check sheets, updates and reporting and/or documenting equipment defects

Critical aspects of evidence
The knowledge and application of relevant sections of: Occupational, health and safety legislation; Statutory legislation; Enterprise/site safety procedures; Enterprise/site emergency procedures
Selecting and assembling lifting gear
Slinging and directing loads
Calculating load weights
Applying anchoring techniques
Applying intermediate rigging techniques

Context of assessment
Competency Standards should be assessed in the workplace or simulated workplace and under the normal range of workplace conditions
Assessment of this unit will be supported with documentary evidence, by means of endorsement stating type and application of work
Interdependent assessment of unit
