UEEHA0020 Conduct detailed inspection of electrical installations for hazardous areas

Modification History

Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package. This unit replaces and is equivalent to UEEHA0001 Conduct detailed inspection of electrical installations for hazardous areas. Prerequisite requirements have been amended.

Application

This unit involves the skills and knowledge required to conduct detailed inspections of the explosion-protection aspects of electrical installations for hazardous areas. It includes using a verification dossier; working safely in a hazardous area; conducting initial, periodic and sample inspections; complying with inspection standards; and recording inspection results. This unit applies to inspection functions. Site-specific work permits may be 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 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. This unit of competency and associated assessment requirements is adopted from clause 2.7 of AS/NZS 4761.1:2018 Competencies for working with electrical equipment for hazardous areas (EEHA). There may be differences between the content of this unit and AS/NZS 4761.1:2018, so the Standard must be checked to ensure compliance with it. Clause 2.7 of AS/NZS 4761.1:2018 includes the following precondition for assessment: “A candidate seeking assessment in this unit shall have been deemed competent to inspect electrical installations in a non-hazardous area at AQF level 3 or NZQF level 4 or higher.”

1.2	Knowledge of the scope of detailed inspections specified in inspection standards and site inspection program is applied to work preparation
1.3	Classification of the area is ascertained from hazardous area layout drawings retained in the verification dossier
1.4	Type and grade of inspection is ascertained from the inspection schedule retained in the verification dossier
1.5	Classification details and specified location of each item of equipment and circuits subject to inspection are determined from design drawings and equipment certification documentation retained in the verification dossier
1.6	Special tools, equipment and testing devices needed to carry out the inspection are checked to ensure they are safe and serviceable, and any defective items are either rectified or replaced
2	Conduct inspection	2.1	Safe work methods relating explosive atmospheres and inspections, including isolation of equipment, are obtained and applied
2.2	Knowledge of the explosion-protection aspects of equipment and hazardous area installation requirements is applied
2.3	Equipment, systems and installation are inspected for compliance with the design specifications retained in the verification dossier and in accordance with the inspection schedule and standards
2.4	Where applicable in a given jurisdiction, an appropriately authorised person is directed to remove equipment enclosure covers and internal components, where needed, to enable inspection
2.5	Arrangements are made to store and protect equipment covers and components that are removed to enable inspection
2.6	Where applicable in a given jurisdiction, after the inspection of each item, an appropriately authorised person is directed to replace equipment covers and components in a manner that ensures the integrity of the explosion-protection system
3	Record results of detailed inspection	3.1	Results of inspection are recorded in accordance with inspection standards
3.2	Defects such as equipment deterioration, faults and unauthorised modifications are recorded in accordance with inspection standards
3.3	Actions to rectify defects are specified in the inspection record
3.4	The inspection record is forwarded to the appropriate personnel for inclusion in the verification dossier in accordance with inspection standards
