UEEHA0006 Maintain equipment associated with hazardous areas

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.
