This Standard specifies the competencies required for persons to work with equipment and installations associated with explosive atmospheres and the performance and knowledge evidence required to assess and attribute competence.
The competencies specified in this Standard relate only to the explosion protection aspects of designated work activities. These competencies are additional to other competencies required for a designated work activity that may be applied for non-explosive atmospheres. The various units in this Standard include pre-requisite competencies that may be relevant to the work activity for hazardous areas As such a candidate seeking assessment needs to also be deemed competent in the designated work activity for non-explosive atmospheres.
NOTES:
1 Although this Standard is intended to be applied with reference to the AS/NZS 60079, and AS/NZS 80079 series, and other AS/NZS standards such as AS/NZS 3800, it may be used in conjunction with other internationally accepted Standards that are in use in specific industries. Examples of these industries include marine, shipping, off-shore oil and gas processing facilities, petroleum, petrochemical, printing, mobile drilling rigs, mining operations and aviation.
2 Other such standards may be referenced for the application of some competency units or where specifically sought for the competency of the personnel concerned. For example, to meet a specific need of an organization.
