Evidence Required



Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessment must confirm the ability to conduct winching operations on ground which is soft enough to simulate the conditions encountered when winching bogged vehicles conduct a winching operation to extricate a light and a mediumheavy rigid vehicle utilise motorised winches winch ropes and associated fittings Consistency in performance Competency should be demonstrated over time using a variety of equipment casualties and situations which the candidate is likely to encounter within the workplace

Context of and specific resources for assessment	Context of assessment Competency should be assessed in areas of difficult terrain incorporating undulating ground Specific resources for assessment Access is required to recovery vehicles and winching equipment actual or simulated equipment casualties specific workplace operating procedures and publications
