Elements and Performance Criteria

1. Prepare to modify/redesign electronics and communications system
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for a given work area are obtained and applied
2. WHS/OHS risk control measures and workplace procedures in preparation for work activity are followed
3. Safety hazards that have not previously been identified are noted on job safety assessment, assessed and risk control measures implemented
4. Appropriate person/s is consulted to ensure the work is coordinated effectively with others involved on the worksite
5. System operating parameters are identified by reviewing system specifications and component technical data
6. Limitations, use and operation of the electronics and communication system to be modified are determined from original specifications, manufacturer data and industry standards
7. Extent of modification is determined from measurements, tests, inspections, system limitations and other relevant requirements
8. Specifications and instructions for the modifications are documented in accordance with job requirements and workplace procedures
9. Tools, equipment, applications and devices needed for the electronics work are obtained in accordance with workplace procedures and checked for correct operation and safety
10. Preparatory work is checked to ensure no unnecessary damage has occurred and complies with job requirements and specifications
11. Generate modification and redesign of electronics and communications system
    • WHS/OHS risk control measures and workplace procedures for carrying out the work are followed
12. Alternative modification is considered and discussed with appropriate person/s
13. Safety, functionality and economic considerations are incorporated in the proposed modification design
14. Proposed communications system modification complies with job requirements and specifications for system design alteration are documented
15. Changes in the use and operation of the communications system as a consequence of the proposed modification are included in the design documentation
16. Unplanned situations are responded to in accordance with workplace procedures, discussions with appropriate person/s and job specifications or requirements in a manner that minimises risk to personnel and equipment
17. Modification and redesign are carried out efficiently without unnecessary waste of materials or damage to electronics apparatus, the surrounding environment or services using sustainable energy principles
18. Complete design and report modification activities
    • WHS/OHS risk control work completion measures and workplace procedures are followed
19. Proposed modification is checked in accordance with workplace procedures for compliance with relevant job requirements and industry standards
20. Worksite is cleaned and made safe in accordance with workplace procedures
21. Proposed modification is submitted for appropriate organisational approval and, as required, statutory or regulatory approval
22. Approved copies of the communications system modification and redesign documents are issued and copies retained, documented and stored in records in accordance with workplace procedures
