iiiIntroductionThis document has been produced by the IFIA Petroleum and Petrochemical Committee to represent a basic body ofknowledge which is expected of a petroleum inspector. A sub-set of 100 of these questions will be used to form theexamination which must be passed as part of the qualification Certified Inspector of Petroleum. The pass level is

75%. Candidates must have completed a minimum of 6 months working as a petroleum inspector and a specifiedprogramme of field training. This is detailed in the IFIA Petroleum Inspector Training Requirements List and must befully documented in the employers internal training records. The Petroleum Inspector Certification Programme is aninternational programme and although details will vary between regions the qualification is international and

transferable. The guidelines governing the Petroleum Inspector Certification Programme outside the Americas aredetermined by the IFIA Petroleum and Petrochemical Committee together with a Technical Advisory Board whichincludes representatives from the Energy Institute and a number of major oil companies. To obtain a copy of theseguidelines or for any other enquiries concerning the programme please visit the website at www.ifiafederation.org.
