Description
This unit of competency covers the skills and knowledge required to interpret process plant schematics for a range of operations uses. This unit of competency applies to operators who are required to find specific information from a schematic, mark up a schematic for their own or someone else’s use, and sketch a schematic using relevant symbols as part of an explanation to another person or as an aide memoir for themselves.This unit of competency applies to a wide range of schematics and covers all general and common symbols. It also includes those specific to the plant which is the operator's area of responsibility and any conventions which are applied by the organisation.No licensing, legislative or certification requirements apply to this unit at the time of publication.
