Certification for mechanical operatives where gas, vapours and dust can create explosive atmospheres

Mechanical (Ex11)

The CompEx Ex11 Mechanical qualification has been developed for mechanical operatives working in hazardous locations where gases, vapours or dusts can form explosive atmospheres.

Attendees

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.

ENTRY REQUIREMENTS:

  • 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.
Prior to attendance on the course, the Employer must provide written evidence of the candidate’s mechanical competency.
Course delegates are required to possess relevant technical qualifications and evidence must be brought to the course.
Candidates who cannot provide evidence of their qualifications or who do not have an employer to complete the competency letter will receive a nontechnical person’s certificate.

Duration

3 days

Delivery

  • Classroom bases theory.
  • Formal practical assessments.

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.

Key learning objectives

Candidates that successfully complete the Ex11 Mechanical qualification will be able to:

  • 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.

Qualification details

Candidates who are successful in both the theory and practical assessments will receive a CompEx Certificate in Core Competence, valid for 5 years from date of issue.

Assessment

Assessment is undertaken using two practical assessments which are Flange Integrity Installation and leak test & Pump set inspections.

Exam

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

WHAT YOU NEED TO BRING:

  • Please bring with you some means of photographic identification i.e. passport, driving licence, company ID card etc.
  • Please refer to the competency pathway document (link below) for supporting documentation/certificates for verification of suitability.
  • For further clarification regarding suitability, please feel free to contact us to discuss.
  • All delegates must wear PPE in the workshop during the practical assessments. You will be provided with all the necessary equipment, tools, stationery and course instruction notes.
  • You will need to wear your own steel cap boots and appropriate work wear.

Please note that PPE needs to be in good condition and free from dirt, oil & grease.

Competency-Pathway Ex11

Please Note: Failure to report promptly each day may result in you missing vital elements of the course and will prevent you from receiving your certificate. As part of the training involves communication in hazardous situations, it is essential that all participants can read, speak and understand English fluently.
