Explanatory notes
1
This unit standard can be assessed in a workplace environment, or in a training or
educational environment if simulated equipment and examples are able to be
provided, or in a combination of both environments.
2
Safety of personnel and plant must be a priority throughout the assessment. If the
safety requirements are not met the assessment must stop and the candidate will be
assessed as not yet competent.
