Unit of competency details

Unit Descriptor 

This unit covers the competency required to maintain, install and remove restraint systems.

This Unit of Competency is applicable to a range of personal restraint systems .

Maintaining a restraint system includes inspecting, isolating faults, replacing, repairing and cleaning prior to returning the item to service. Maintenance can be conducted in-situ or the item can be removed to a maintenance facility.

Installing a restraint system involves attachment to a parent system.

Application of the Unit 

The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package.

This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.

Elements describe the essential outcomes of a Unit of Competency.

Performance Criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the Required Skills and Knowledge and/or the Range Statement. Assessment of performance is to be consistent with the Evidence Guide.

ELEMENT

PERFORMANCE CRITERIA

1. Maintain restraint belts /harnesses 

1.1 Restraint belts/harnesses are inspected for serviceability in accordance with standard procedures 

1.2 Identified faults  beyond own authority to rectify are reported to supervisor and faulty restraint system is quarantined

1.3 Unserviceable parts of a quick release fitting are inspected, tested and replaced

1.4 Unserviceable parts of the restraint belts /harnesses  are replaced to render restraint system serviceable in accordance with standard procedures

1.5 Basic restraint belts/harnesses stitching repairs are completed in accordance with standard procedures

1.6 Restraint belts/harnesses are cleaned in accordance with standard procedures

1.7 Restraint belts/harnesses are presented for inspection by supervisor and work is not progressed until supervisor has completed inspections in accordance with standard procedures

1.8 Relevant documentation is completed in accordance with standard procedures

2. Install and remove restraint systems 

2.1 Authority to fit or remove restraint system is obtained in accordance with standard procedures

2.2 Restraint system is fixed or removed from parent system in accordance with standard procedures

2.3 Restraint system is presented for inspection by supervisor and work is not progressed until supervisor has completed inspections in accordance with standard procedures

2.4 Relevant documentation is completed in accordance with standard procedures

EVIDENCE GUIDE 

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 limitations/tolerances 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.
