Elements and Performance Criteria

1. Apply specific health and safety considerations to surface preparation
   • Products, hazardous materials and processes used in blaster cleaning and coating operations are identified.
   • Safety procedures appropriate to the work requirements are applied.
   • Unsafe working conditions are identified and reported to appropriate personnel.
2. Control by-products, materials and emissions
   • By-products, materials and emissions are contained using established procedures.
   • By-products, materials and emissions are monitored and directed to appropriate treatment or storage area.
   • Monitoring devices are checked for correct/continuous operation.
   • Status/reports are recorded and reported.
3. Dispose of by-product, materials and emissions
   • Waste treatment processes are applied in accordance with standard operating procedures.
   • Treatment processes are carried out in accordance with standard operating procedures and to meet relevant authority waste requirements.

Required Skills

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	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 byproducts 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 supervisors 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

Range Statement

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.
Products, hazardous materials and processes	All products, hazardous materials and processes that are subject to codes and/or regulations in use
Monitoring devices	pH meters, probes
Waste treatment processes	Neutralisation, metals precipitation, solid separation-gravity/centrifuging
