Key Learning Outcomes

  • Identify the correct national regulations, directives and IEC standards which are applicable to hazardous dust locations.
  • Identify the correct criteria and descriptors used to classify a hazardous dust location.
  • Recognise the correct characteristics of common hazardous dust, fibres and flyings – i.e. combustible, conductive and non-conductive.
  • Demonstrate an underpinning knowledge of how Ex electrical equipment is certified, including Ex i ,iD, ‘m’, ‘p’, ‘pD’, ‘t’, ‘tD’, ‘d’, ‘e’, ‘m’, ‘o’, ‘q’, ‘s’, how it maintains its protection concept and how it is to be selected, installed, inspected and maintained.
  • Identify the correct test value readings for IS and non-IS installations and equipment.
  • Use IEC inspection table 1 and inspect pre-installed Ex’d’, ‘e’ and ‘n’, ‘t’, ‘tD’ electrical equipment.
  • Interpret Intrinsically Safe (IS) documentation.
  • Use IEC inspection table 2 and inspect pre-installed certified, non-certified, simple and associated apparatus on a pre-installed intrinsically safe installation.
  • Identify and record faults at the correct grade of inspection.
  • Recommend the correct remedial action and IEC inspection code for each fault identified.
  • Recognise the need to prove an isolation on electrical equipment prior to carrying out a detailed inspection.
  • Use the correct documentation
