This Competency Standard Unit covers assessing the Certification documentation of explosion-protected equipment with a certificate of conformity other than an IECEx, ANZEx or AUS Ex Certificate, and producing a conformity assessment document. It encompasses skills and knowledge to examine and compare document content, compare requirements of IEC or AS/NZS Standards with alternative Standards on which the original certification was based, knowledge of explosion-protection techniques and technical report writing.

This unit is directly equivalent to the Unit 2.9 Conduct a conformity assessment of explosion-protected equipment in the Australian/New Zealand Standard AS/NZS 4761.1 Competencies for working with electrical equipment for hazardous areas (EEHA) Part 1: Competency Standards. Equivalence includes endorsement in the explosion-protection techniques listed in the Range statement of this unit.

Study level:
Vocational and further education (TAFE)
Unit code:
UEENEEM036A

Prerequisites

A student must be confirmed competent in compliance assessment of electrical/electronic equipment and general technical evaluation and report writing at AQF 5 or equivalent, as a pre-requisite to this unit.

Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills and knowledge: - occupational health and safety responsibilities related to hazardous areas; - the roles of the parties involved in the safety of hazardous areas; - properties of combustible substances and their potential to create an explosive hazard; - the nature of hazardous areas; - explosive-protected equipment; - explosion-protection equipment- ex certification schemes; - flameproof (ex 'd') explosion-protection technique; - increased safety (ex 'e') explosion-protection technique; - non-sparking (ex 'n') explosion-protection technique; - intrinsic safety (ex 'i') explosion-protection technique; - pressurization (ex 'p') explosion-protection technique; - enclosures for dusts (ex 'td') - explosion-protection technique; - common characteristics of explosion-protection techniques; - the compliance certification and the 'ex' scheme for recognition of certification; - the preparation required to assess explosion-protected equipment for compliance with standards; - assessing and testing explosion-protected equipment; - documentation used in assessing explosion-protected equipment for conformance to accepted standards; - assessing to a current acceptable standard existing equipment that has been certified to previously acceptable standards, and; - a clause by clause assessment between the equipment manufacturing standard(s) and the current acceptable ex standards.
