This standard is about positioning and installing mechanical equipment and systems in engineering construction plant.
You will need to be able to position and install mechanical equipment and systems, following relevant engineering drawings and specifications whilst adhering to health, safety and environmental legislation, regulations and safe working practices.
In the context of this standard, your responsibility is to work within detailed specifications and clearly defined procedures.  In some cases, you may still be expected to refer to others for final authorisations, even though you remain responsible for identifying and implementing decisions.
This standard is for
This standard is for mechanical fitters and mechanical maintenance technicians.
