Elements and Performance Criteria

1. Maintain restraint belts/harnesses
   • Restraint belts/harnesses are inspected for serviceability in accordance with standard procedures
   • Identified faults beyond own authority to rectify are reported to supervisor and faulty restraint system is quarantined
   • Unserviceable parts of a quick release fitting are inspected, tested and replaced
   • Unserviceable parts of the restraint belts/harnesses are replaced to render restraint system serviceable in accordance with standard procedures
   • Basic restraint belts/harnesses stitching repairs are completed in accordance with standard procedures
   • Restraint belts/harnesses are cleaned in accordance with standard procedures
   • Restraint belts/harnesses are presented for inspection by supervisor and work is not progressed until supervisor has completed inspections in accordance with standard procedures
   • Relevant documentation is completed in accordance with standard procedures
2. Install and remove restraint systems
   • Authority to fit or remove restraint system is obtained in accordance with standard procedures
   • Restraint system is fixed or removed from parent system in accordance with standard procedures
   • Restraint system is presented for inspection by supervisor and work is not progressed until supervisor has completed inspections in accordance with standard procedures
   • Relevant documentation is completed in accordance with standard procedures

Evidence Required

Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessment must confirm the ability to recognise limits of own authority and to recognise a range of faults and their serviceability and repair limitationstolerances including verification of expiry date of restraint system component parts and recognition of incorrect manufacture Consistency in performance Competency should be demonstrated over time with a range of restraint system fitting and maintenance activities
Context of and specific resources for assessment	Context of assessment Competency should be assessed in the workplace or in a simulated workplace environment Specific resources for assessment Access to harness components harness webbing for repairs industrial sewing machine tools and equipment for maintaining and fixing a restraint system quick release fittings and components
