Prepare explosives for metal hardening

Assessment tool

Version 1.0
Issue Date: April 2024


This unit was developed for specialists working within proof and trials organisations within Defence but may be applicable to any individual in this field of work.

Typically these individuals must demonstrate the ability to work independently or as part of a team under direct and/or indirect supervision, use discretion and judgement, and take responsibility for the quality of their output. All activities are carried out in accordance with relevant organisational policies and procedures.

This unit covers the competency required to prepare explosives for metal hardening.

Metal hardening using sheet explosives is a specialised application of explosives and is used to harden metals such as rail points.

This unit does not cover firing of the charges, which is covered in DEFEO803A Conduct static proof tests.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to:

prepare explosives for metal hardening

maintain the relevant records

Consistency in performance

Competency should be demonstrated over time in a variety of metal hardening environments or in a simulated environment.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in an actual or simulated activity.

Specific resources for assessment

Access is required to:

licensed explosive workshop

sheet explosives

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

Submission Requirements
