please be care of the word "circuit" that means it contains associated apparatus which if it is placed in an explosive atmosphere, it shall be protected by an appropriate Type of Protection suitable for the area classification

3.1.2 associated apparatus electrical equipment which contains both intrinsically safe circuits and non-intrinsically safe circuits and is constructed so that the non-intrinsically safe circuits cannot adversely affect the intrinsically safe circuits

Okay, but would this imply that the I.S circuit is installed incorrectly ? E.g if you installed an ib/ic circuit in zone0. Or in your example that the apparatus is not fit for purpose. The point being that just because the circuit is supplied via some kind of IS barrier doesn’t mean it’s necessarily safe (Just trying to improve my understanding, going on the course next week, thanks for replying!)

@@benwaine9981 that is what I mean, but I think you are right. I should correct this answer and exclude this choice. Because I can't consider it an answer, and it only comes true in certain cases thank you very much

@@benwaine9981 please pay attention for 6:20

4.5 Qualifications of personnel The design of the installation, the selection of equipment and the erection covered by this standard shall be carried out only by persons whose training has included instruction on the various types of protection and installation practices, relevant rules and regulations and on the general principles of area classification. The competency of the person shall be relevant to the type of work to be undertaken (see Annex A). Annex A Knowledge, skills and competencies of responsible persons, operatives/technicians and designers A.1 Scope Annex A specifies the knowledge, skills and competencies of persons referred to in this standard. A.2 Knowledge and skills A.2.1 Responsible persons Responsible persons who are responsible for the processes involved in the design, selection and erection of explosion protected equipment shall possess, at least, the following: a) general understanding of relevant electrical engineering; b) understanding and ability to read and assess engineering drawings; c) practical understanding of explosion protection principles and techniques; d) working knowledge and understanding of relevant standards in explosion protection; e) basic knowledge of quality assurance, including the principles of auditing, documentation, traceability of measurement and instrument calibration. Such persons shall confine their involvement to the management of competent operatives conducting selection and erection duties and not engage themselves directly in the work without ensuring their practical skills at least meet the requirements given in A.2.2. A.2.2 Operatives/technicians (selection and erection) Operatives/technicians shall possess, to the extent necessary to perform their tasks, the following: a) understanding of the general principles of explosion protection; b) understanding of the general principles of types of protection and marking; c) understanding of those aspects of equipment design which affect the protection concept; d) understanding of content of certificates and relevant parts of this standard; e) general understanding of inspection and maintenance requirements of IEC 60079-17; f) familiarity with the particular techniques to be employed in the selection and erection of equipment referred to in this standard; g) understanding of the additional importance of permit to work systems and safe isolation in relation to explosion protection. A.2.3 Designers (design and selection) Designers shall possess, to the extent necessary to perform their tasks, the following: a) detailed knowledge of the general principles of explosion protection; b) detailed knowledge of the general principles of types of protection and marking; c) detailed knowledge of those aspects of equipment design which affect the protection concept; d) detailed knowledge of content of certificates and relevant parts of this standard; e) understanding of practical skills for the preparation and installation of relevant concepts of protection; f) detailed knowledge of the additional importance of permit to work systems and safe isolation in relation to explosion protection; g) detailed knowledge of the particular techniques to be employed in the selection and erection of equipment referred to in this standard; h) general understanding of inspection and maintenance requirements of IEC 60079-17. A.3 Competencies A.3.1 General Competencies shall apply to each of the explosion protection techniques for which the person is involved. For example: it is possible for a person to be competent in the field of selection and erection of Ex “i” equipment only and not be fully competent in the selection and erection of Ex “d” switchgear or Ex “e” motors. In such cases, the person's management shall define this in their documentation system. A.3.2 Responsible persons Responsible persons shall be able to demonstrate their competency and provide evidence of attaining the knowledge and skill requirements specified in A.2.1 relevant to the types of protection and/or types of equipment involved. A.3.3 Operatives/technicians Operatives/technicians shall be able to demonstrate their competency and provide evidence of attaining the knowledge and skill requirements specified in A.2.2 relevant to the types of protection and/or types of equipment involved. They shall also be able to demonstrate their competency with documentary evidence in the: a) use of documentation in 4.2; b) production of reports, e.g. inspection reports, to the user as identified in 4.2; c) practical skills necessary for the preparation and installation of relevant concepts of protection; d) use and production of installation records as identified in 4.2. A.3.4 Designers Designers shall be able to demonstrate their competency and provide evidence of attaining the knowledge and skill requirements specified in A.2.3 relevant to the types of protection and/or types of equipment involved. They shall also be able to demonstrate their competency with documentary evidence in the: a) production of documentation specified in 4.2; b) production of designers certificates to the user as identified in 4.2; c) practical skills necessary for the preparation and compilation of relevant design details for the concepts of protection and systems involved; d) updated and production of installation records as identified in 4.2. A.4 Assessment The competency of responsible persons, operatives and designers shall be verified and attributed, at intervals relevant to national regulations or standards or user requirements, on the basis of sufficient evidence that the person: a) has the necessary skills required for the scope of work; b) can act competently across the specified range of activities; and c) has the relevant knowledge and understanding underpinning competency.

Hand skills is a mandatory to be capable to pass the exam, you will do around 6 glands for Ex01 module one of them is a barrier gland

Glad it helped!

I'm done thish course @anu6569

For sure, roshan it is essential now to work for Oil & Gas industry, do you remember what happened for Deepwater Horizon offshore drilling rig

Look for local agent and register for the course, cost around 2500 usd

What do you mean?

The CompEx Ex01-Ex04 Gas and vapours has been developed for electrical and instrument technicians working in hazardous locations where gases and vapours can form hazardous atmosphere

Sure it is Recommended,

It is 5 days course, 3 days for illustration and 2 days for exam

All the best

Hi Azfar I can't see a problem to go through your plan, the core concept for construction , already you have , I believe just you have to pay more attention to the hazardous area classification and equipment selection, that what you will find if you get CompEx training course
