Critical aspects of evidence
It is essential that competence is assessed in the critical aspects of:
The knowledge and application of relevant sections of occupational health and safety legislation, statutory legislation, enterprise/site safety procedures; enterprise/site emergency procedures; attainment of electrical licence, where appropriate, deeming competency associated with electrical work; preparation and planning of work; verification techniques; diagnostic and fault finding techniques and procedures; repair techniques and procedures; completion of work procedures
Context for assessment
Competency standards should be assessed in the workplace or simulated workplace and under the normal range of workplace conditions.
Assessment of this unit will be supported with documentary evidence, by means of endorsement stating type and applications of work.
