Elements and Performance Criteria

1. 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.
2. 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

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 flyrock 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
