Guidance Information
1This unit standard is intended for, but not restricted to, workplace assessment.
2Safety of personnel and plant must be a priority throughout the assessment. If the safety requirements are not met the assessment must stop.
3Performance and work practices in relation to the outcomes and performance criteria requirements must comply with all current legislation, especially the Electricity Act 1992, and any regulations and codes of practice recognised under that statute; the Health and Safety at Work Act 2015; and the Resource Management Act 1991. Electricity supply industry codes of practice and documented industry procedures include the current version of the Safety Manual – Electricity Industry (SM-EI) Wellington: Electricity Engineers’ Association. A full list of current legislation and industry codes is available from Connexis Infrastructure ITO.
4The phrase in accordance with industry requirements is implicit in all outcomes and performance criteria in this unit standard.
5Industry requirements include all industry and workplace documented policies, procedures, specifications, business, and quality management requirements relevant to the workplace in which assessment is carried out.
