Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessment must confirm the ability to comply with:
organisational safety requirements
appropriate legislative and regulatory requirements
Assessment must also confirm the ability to work safely within an explosive ordnance environment and to:
calculate and apply net explosive quantity
assess and apply compatibility
maintain documentation
Consistency in performance
Competency should be demonstrated in a range of actual or simulated explosive ordnance contexts.
Context of and specific resources for assessment
Context of assessment
Competency should be assessed in the workplace or in a simulated work environment, in accordance with all relevant legislation and organisation requirements.
Specific resources for assessment
Access is required to:
facilities and resources used in the storage, distribution or maintenance of explosive ordnance, including a licensed explosive site.
Method of assessment
This unit may be assessed with the following unit:
DEFEO101D Work safely with explosive ordnance.
In a public safety environment assessment is usually conducted via direct observation in a training environment or in the workplace via subject matter supervision and/or mentoring, which is typically recorded in a competency workbook.
Assessment is completed using appropriately qualified assessors who select the most appropriate method of assessment.
Assessment may occur in an operational environment or in an industry-approved simulated work environment. Forms of assessment that are typically used include:
direct observation
interviewing the candidate
journals and workplace documentation
third party reports from supervisors
written or oral questions
