Elements and Performance Criteria

1. Prepare to maintain microbial control of air and water systems
   • Work health and safety (WHS)/occupational health and safety (OHS) hazards, risk control methods, relevant standards, codes and legislation are obtained and applied in accordance with workplace procedures
2. Safety hazards which have not been previously identified are noted on risk assessment documents and risk control measures determined and implemented
3. Maintenance schedule and process compliance requirements are confirmed and appropriately sequenced in accordance with legislative, industry standards and code requirements and established procedures
4. Appropriate person/s is consulted to ensure the work is coordinated effectively with others involved on the worksite
5. Location of equipment to be maintained is determined from maintenance schedule, workplace procedures and/or system specifications and diagrams
6. Resources needed to conduct the maintenance are obtained in accordance with workplace procedures and checked against job requirements
7. Tools, equipment and testing devices needed to conduct the maintenance work are obtained in accordance with workplace procedures and checked for correct operation and safety
8. Maintain microbial control of air and water systems
   • Circuits/machines/plant are checked and isolated in accordance with WHS/OHS requirements and workplace procedures
9. Water samples are taken and tested in accordance with legislative, industry standards and code requirements and established methods and routines
10. Air and water system apparatus to be maintained is inspected and evaluated for compliance with legislative, industry standards and code requirements in accordance with maintenance schedule.
11. Non-compliant apparatus/components/samples are documented and arrangements made for their rectification in accordance with workplace procedures
12. Unplanned situations are responded to in accordance with workplace procedures in a manner that minimises risk to personnel and equipment
13. Ongoing checks of quality of maintenance work are undertaken in accordance with workplace procedures
14. Maintenance process compliance is performed efficiently without waste of materials or damage to apparatus, the surrounding environment or services using sustainable energy practices
15. Complete maintenance processes and documentation
    • Worksite and equipment are cleaned and made safe in accordance with workplace procedures
16. Final checks are made to verify that the maintenance complies with maintenance requirements
17. Maintenance completion is documented and appropriate person/s notified in accordance with established procedures and regulations
