Training courses and seminars


Duration 2/3 days

Within Europe all explosion-proof equipment and systems fall under several ATEX EU Directives. This includes anything used within, or in conjunction with, a potentially explosive atmospheres such as safety, control and regulation devices and protective components, equipment and systems.

The 2 days basic training course provides an overview of ATEX Directives focusing on contents and requirements of 94/9/EC (Equipment Directive) but also providing an overview of 99/92/EC (Workplace Directive) and Hazardous Area Classification (HAC) process.

The 1 day extra module can provide a more detailed training on HAC according to the methodology stated in European EN IEC codes (60079-10-1 and 60079-10-2) and compare it to other international standards such as API 5000/505 and IP-15 through the examination of test cases.


Participants will develop a general knowledge of ATEX requirements for plant design (starting from HAC), equipment marking and selection, operating and maintenance. The workshop will provide case studies aimed at improving the familiarity with the techniques and methodologies to be applied.

Who should attend?

Project Managers and Project Engineers, Process Engineers and Electrical Engineers, Key HSE Functions and Supervisors, Operation and Maintenance Managers and Inspection Surveyors.
