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 worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:

knowledge of the requirements, procedures and instructions for the monitoring and control of the effects of blasting

implementation of procedures and techniques for the safe, effective and efficient monitoring and control of the effects of blasting

working with others to plan, prepare and conduct the monitoring and control of the effects of blasting

provision of clear and timely instruction and supervision by the individual of those involved in the monitoring and control of the effects of blasting

evidence of the consistent successful monitoring and control of the effects of blasting

Context of and specific resources for assessment

This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.

The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.

Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.

Aboriginal people and other people from a non English speaking background may have second language issues.

Assessment of this competency requires typical resources normally used in a resources and infrastructure sector environment. Selection and use of resources for particular worksites may differ due to the site circumstances.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Method of assessment

This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:

written and/or oral assessment of the candidate's required knowledge

observed, documented and/or first hand testimonial evidence of the candidate's:

implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes

consistently achieving the required outcomes

first hand testimonial evidence of the candidate's:

working with others to plan, prepare and conduct the monitoring and control of the effects of blasting

provision of clear and timely instruction and supervision by the individual of those involved in the monitoring and control of the effects of blasting

Required skills

Specific skills are required to achieve the performance criteria in this unit, particularly for the application in the various circumstances in which this unit may be applied. This includes the ability to carry out the following as required to monitor and control the effects of blasting:

apply legislative, organisation and site requirements and procedures

access, interpret and apply safety rules and procedures

plan and coordinate work

assess the risks and hazards attached to explosives in the environment

interpret the impact of blast design on ground vibration, air blast and flyrock

interpret and apply manufacturer's instructions

audit data and apply to blasting strategy

Required knowledge

Specific knowledge is required to achieve the Performance Criteria of this unit, particularly its application in a variety of circumstances in which the unit may be used. This includes knowledge of the following, as required to monitor and control the effects of blasting:

legislative and statutory requirements and procedures

sources of legislation

differing geological features and conditions' effect on ground vibration, air blast and flyrock

portable monitoring equipment characteristics, technical capabilities and limitations

maintenance surveys and procedures

audit and review processes and techniques

procedures for estimation of ground vibration levels

procedures for estimation of blast overpressure

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
