    • P&ID drawings
    • Loop sheets
    • Process control system
    • Front end elements
    • Final elements
    • Systems
    • Site procedures
    • Operating manuals and procedures
  • Skill in:
    • Interpreting a loop drawing to identify the devices in a particular loop
    • Interpreting complex technical documents
    • Understanding process control
    • Interpreting P&IDs

Task 2: Identify any discrepancies between observed and proper operation of the control system in order to determine whether a problem exists.
  • Knowledge of:
    • Process control
    • Loop and data sheets
    • P&ID drawings
    • Operating manuals and procedures
    • Problem-solving techniques
  • Skill in:
    • Identifying abnormal variations in data or readings from charts, or indicators
    • Identifying malfunctions in equipment and possible causes for these malfunctions
    • Reading technical documents

Task 3: Determine which device or devices of the control system could be causing the observed discrepancies in order to formulate a plan of corrective action.
  • Knowledge of:
    • Process control
