Elements and Performance Criteria

  1. Identify instrumentation drawings, specifications, industry standards and equipment manuals
  2. Need for instrumentation drawings, specifications, industry standards or equipment manuals is determined for the work to be undertaken
  3. Instrumentation drawings, specifications, industry standards or equipment manuals required for the work to be undertaken are obtained in accordance with workplace procedures
  4. Use instrumentation drawings, specifications, industry standards and equipment manuals
  5. Instrumentation drawings, specifications, industry standards and equipment manuals are interpreted using information from process controls, instrumentation drawing layouts, conventions and symbols
  6. Dimensions are extracted and applied from drawings and diagrams for application to work being undertaken
  7. Location of equipment is determined from instrumentation drawings and specifications
  8. Connections between pneumatic, hydraulic and electrical equipment are determined from instrumentation drawings and specifications
  9. Equipment manuals are reviewed to ascertain content, format and located information are relevant to the work to be undertaken
  10. Convey instrumentation information using drawings and diagrams
  11. Instrumentation drawing conventions are used to neatly correct freehand original job drawing to show final 'as-installed' arrangement
  12. Corrected drawings are forwarded to appropriate person/s in accordance with workplace procedures
