Issue Date: April 2024


Qualification -
Unit of Competency AHCEXP302A - Identify and select explosive products
Description This unit covers the process of identifying and selecting explosive products and/or suitable mixtures that can be used for blasting for agricultural or land management purposes and defines the standard required to: establish the need to use explosives; identify the risks and environmental implications of using explosives; select explosives and initiator devices to match the application; site and identified hazards at the blasting site; utilise safety fuses as required; select appropriate fly-rock control devices.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit is likely to be carried out unsupervised. Responsibility for the safety of others is an important part of the application of this standard.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Elements of Competency Performance Criteria              
Element: Identify explosives applications
  • The job application requiring the use of explosives is identified in consultation with the field manager or supervisor.
  • The site for blasting is accurately identified and the surrounding area checked to confirm that all aspects of safety have been considered and actioned.
  • Potential side effects of the blast are identified in consideration of all site characteristics and are used in the planning of blasting operations.
  • Environmental implications of the intended explosives usage are considered in the planning of blasting activities.
  • Alternatives to the use of explosives are considered in the planning of the application and are utilised as appropriate.
       
Element: Select explosives components
  • Explosives are selected to match the application, site and identified hazards at the blasting site.
  • The quantity of explosive energy required is established in line with the site characteristics and the designated application.
  • Initiator device selection reflects industry best practice and is matched to explosives selection.
  • Safety fuses are utilised as required to suit the application.
       


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, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

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

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

establish the need to use explosives

identify the risks and environmental implications of using explosives

select explosives and initiator devices to match the application, site and identified hazards at the blasting site

utilise safety fuses as required

select appropriate fly-rock control devices.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

examine explosives and determine their classification

select explosives for particular tasks

estimate the likely effect of explosives on structures, personnel and livestock in the site vicinity

select appropriate fly-rock control devices, e.g., blasting mats as required

use literacy skills to read, interpret and follow organisational policies and procedures, follow sequenced written instructions, record accurately and legible information collected and select and apply procedures for a range of tasks

use oral communication skills/language competence to fulfil the job role as specified by the organisation, including questioning techniques, active listening, clarifying information and consulting with supervisors as required

use numeracy skills to estimate, calculate and record routine workplace measures

use interpersonal skills to work with and relate to people from a range of cultural, social and religious backgrounds and with a range of physical and mental abilities.

Required knowledge

identification of the components of various explosive products

indications for the uses of various explosive products

performance of various explosive products, the behaviour of the substrate material (e.g., sand, soil, rock, etc.) when subject to blasting

jobs requiring the use of explosives (e.g., blowing stumps, rabbit warrens, excavating a dam site and excavation requirements, fence post holes, tree or vine holes, rock floaters, etc.)

particular properties of explosives/blasting agents and their suitability for particular purposes

explosives/blasting agents or ammonium nitrate/Fuel Oil (ANFO)

compounds mixed on site.

explosive compounds such as:

water gels

slurries

emulsions

ammonium nitrate explosives (ANFO)

black powder

special purpose explosives.

Relevant legislation may include:

Australian Standards and legislation that relate to this standard are Australian Standards - A2187.1 1998: Storage and land transport.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
