Hazardous Areas CompEx Dust Course (Ex05 & Ex06)

  /    /  Hazardous Areas CompEx Dust Course (Ex05 & Ex06)

Overview

CompEx Dust (Ex05-Ex06) meets the competency requirements of IEC60079-14, 17 in selection, installation, inspection and maintenance of electrical equipment in potentially explosive dust atmospheres. The course consists of classroom based theoretical training, practice sessions and practical skill & theory assessments. The course includes instruction on how to read hazardous area certification, labeling and documentation relating to dust factors that need to be considered when managing dust clouds and layers. It also covers the main protection concepts, categories and levels that are applied to certified Ex electrical equipment.

Candidates who have successfully completed the Ex05-Ex06 qualification will be able to:
– 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
– 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.
