Unit Of competency

Modification History

Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package.

Application

This unit involves the skills and knowledge required to maintain equipment associated with hazardous areas. It includes determining required remedial maintenance from inspection reports; carrying out remedial and breakdown maintenance in compliance with regulations and safe working methods, standards and manufacturer’s instructions; and completing the necessary maintenance documentation. It is adopted from clause 2.6 of AS/NZS 4761.1:2018 Competencies for working with electrical equipment for hazardous areas (EEHA).

For the purpose of applying this unit, 'hazardous areas' are defined as areas in which an explosive atmosphere may be present.

Site-specific work permits maybe required to work in the hazardous environment. In addition, other permits may be required, such as confined space and to operate specific pieces of equipment such as elevated work platforms (EWPs) in various jurisdictions.

Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.

Assessment requirements

Modification History

Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package.

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least two separate occasions and include:

  • preparing to undertake maintenance of electrical equipment associated with explosive atmospheres, including:
  • reviewing safe work methods associated with the classified area in which the work is to be carried out
  • ascertaining the area classification and details of equipment from documentation held in the verification dossier
  • reviewing inspection records to determine the extent of remedial maintenance
  • evaluating the extent of breakdown maintenance in consultation with reporting personnel
  • consulting with technical personnel to determine the limits of maintenance and repair that can be carried out in situ
  • checking the safety of compliant tools, equipment and testing devices required to carry out the inspection
  • maintaining electrical equipment associated with explosive atmospheres as specified in the inspection records, including:
  • following safe work methods relating the work, including isolation of equipment
  • adjusting and repairing equipment within the limits permitted by the equipment certification regulations and in accordance with manufacturer’s instructions
