Ex11 Mechanical

This qualification is suitable for practicing mechanical operatives who are involved in installing, inspecting and maintaining non-electrical (mechanical) equipment in locations where gases, vapours and/or dusts can potentially create a hazardous area.

All courses

 

Course information and target audience

This course has been developed in consultation with industry to ensure the core competence of mechanical workers who operate in hazardous environments. The course consists of a single unit, which incorporates elements from the CompEx Foundation qualification (ExF) to include fundamentals in hazardous awareness and Ex principles.

Candidates will learn about the safety considerations that should be applied to work areas that contain potentially explosive or flammable atmospheres and the factors that are used to classify their location.

The course includes instruction on how to read hazardous area certification, labelling and documentation, and also informs candidates about the main protection concepts, categories and levels that are applied to certified Ex electrical and mechanical equipment.

Successful candidates will demonstrate the knowledge and skills to meet the appropriate requirements in the IEC 60079 and ISO 80079 series of standards as well as any relevant national standards and directives.

ENTRY REQUIREMENT

  • Practicing competent mechanical operatives

  • Practicing competent multi-skilled operatives

  • Mechanical engineers with previous practical experience

  • Electro-mechanical engineers with previous practical experience

  • Prior CompEx certification supported by employer sponsored letter

Key Learning Objectives

Identify the correct national regulations, directives and IEC/ISO standards which are applicable to hazardous locations containing non-electrical (mechanical) equipment.

  • Identify the correct criteria and descriptors used to classify a hazardous location.

  • Recognise the correct characteristics of common hazardous gases, vapours and dusts discussed during the course.

  • Demonstrate an understanding of the basic method and requirements for non-electrical equipment for hazardous locations (constructional safety ‘c’, control of ignition source ‘b’ and liquid immersion ‘k’)

  • Demonstrate an understanding of how certified Ex non-electrical equipment maintains its protection concept and how it is to be selected, installed, inspected and maintained.

  • Demonstrate an understanding of how certified Ex electrical equipment maintains its protection concept and how it is to be selected, installed, inspected and maintained

  • Demonstrate an understanding of required correct equipment selection, e.g. flange, gaskets, bolts and use of current industry flange installation practices.

  • Demonstrate an understanding of leak testing requirements of installed flange arrangements

 

 

Assessment

Assessment is undertaken using both practical assessments and an online examination that covers the CompEx units Ex Foundation and Ex11.

Theory exam

Candidates must undertake a multiple-choice online examination that consists of 60 questions answered over 1.5 hours.

Practical assessments:

Candidates are required to undertake two practical assessments:

  • Ex11 – Flange Integrity Installation and leak test – 60 minutes

  • Ex11 – Pumpset inspections (visual and detailed) – 60 minutes.
