ELEMENT 

PERFORMANCE CRITERIA 

1. Apply specific health and safety considerations to surface preparation

1.1. Products, hazardous materials and processes used in blaster cleaning and coating operations are identified.

1.2. Safety procedures appropriate to the work requirements are applied.

1.3. Unsafe working conditions are identified and reported to appropriate personnel.

2. Control by-products, materials and emissions

2.1. By-products, materials and emissions are contained using established procedures.

2.2. By-products, materials and emissions are monitored and directed to appropriate treatment or storage area.

2.3. Monitoring devices are checked for correct/continuous operation.

2.4. Status/reports are recorded and reported.

3. Dispose of by-product, materials and emissions

3.1. Waste treatment processes are applied in accordance with standard operating procedures.

3.2. Treatment processes are carried out in accordance with standard operating procedures and to meet relevant authority waste requirements.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Look for evidence that confirms skills in:

• collecting, storing and removing samples of by-products
• monitoring and transferring by-product and emissions
• checking monitoring devices
• implementing waste treatment process
• recording and reporting of all results
• collecting, storing, removing and sampling by-products

Required knowledge 

Required knowledge

• Look for evidence that confirms knowledge of:
• products, hazardous materials and processes within the scope of this unit
• regulatory and legislative requirements relating to control of blast coating by-products, materials and emissions
• procedures for collecting samples
• by-product collection equipment operation methods
• waste control monitoring equipment and procedures
• waste treatment processes
• requirements and procedures for recording and reporting process status reports
• hazards and control measures associated with controlling blast coating by-products, materials and emissions
• use and application of personal protective equipment

EVIDENCE GUIDE 

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 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

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

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with controlling blast coating by-products, materials and emissions or other units requiring the exercise of the skills and knowledge covered by this unit.

Context of and specific resources for assessment 

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Method of assessment 

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
