CompEx 01-04 (Gas & Vapours)

Description/Objectives

The CompEx Ex01-Ex04 Gas and vapours qualification has been developed for electrical and instrument technicians working in hazardous locations where gases or vapours can form explosive atmospheres. Practical “hands-on” training and assessment take place in a realistic simulated environment, giving attendees a comprehensive learning experience that is directly related to a true industry setting.  This qualification focuses on the minimum specifications identified in IEC60079:0, IEC60079:10.1, IEC60079:14 and IEC6007

Upon completion of the CompEx Ex01-04 course the student will be able to: 

  • Demonstrate installation and inspections skills in hazardous areas.
  • Understand basics of Ex protection methods and where each may be used.
  • Demonstrate understanding of Ex markings
  • Understand which activities are and are not allowed with regards to maintenance and repairs.
