What an assessment for UEEHA0020 must cover

22 assessable components: 3 elements (16 performance criteria), 3 performance evidence and 3 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare for inspection

1.1WHS/OHS procedures and safe work methods are reviewed in preparation to work in a classified hazardous area
1.2Knowledge of the scope of detailed inspections specified in inspection standards and site inspection program is applied to work preparation
1.3Classification of the area is ascertained from hazardous area layout drawings retained in the verification dossier
1.4Type and grade of inspection is ascertained from the inspection schedule retained in the verification dossier
1.5Classification details and specified location of each item of equipment and circuits subject to inspection are determined from design drawings and equipment certification documentation retained in the verification dossier
1.6Special tools, equipment and testing devices needed to carry out the inspection are checked to ensure they are safe and serviceable, and any defective items are either rectified or replaced

2 Conduct inspection

2.1Safe work methods relating explosive atmospheres and inspections, including isolation of equipment, are obtained and applied
2.2Knowledge of the explosion-protection aspects of equipment and hazardous area installation requirements is applied
2.3Equipment, systems and installation are inspected for compliance with the design specifications retained in the verification dossier and in accordance with the inspection schedule and standards
2.4Where applicable in a given jurisdiction, an appropriately authorised person is directed to remove equipment enclosure covers and internal components, where needed, to enable inspection
2.5Arrangements are made to store and protect equipment covers and components that are removed to enable inspection
2.6Where applicable in a given jurisdiction, after the inspection of each item, an appropriately authorised person is directed to replace equipment covers and components in a manner that ensures the integrity of the explosion-protection system

3 Record results of detailed inspection

3.1Results of inspection are recorded in accordance with inspection standards
3.2Defects such as equipment deterioration, faults and unauthorised modifications are recorded in accordance with inspection standards
3.3Actions to rectify defects are specified in the inspection record
3.4The inspection record is forwarded to the appropriate personnel for inclusion in the verification dossier in accordance with inspection standards

Questions about assessing UEEHA0020

What does an assessment tool for UEEHA0020 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEEHA0020 needs to address all 22 unit components: 3 elements with 16 performance criteria, 3 performance evidence requirements, 3 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for UEEHA0020?

Auditori pulls the current release of UEEHA0020 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for UEEHA0020 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing UEEHA0020 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of UEEHA0020, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
