Elements and Performance Criteria

1. Determine job requirements
   • Surface preparation requirements are determined from job sheet, instructions or other predetermined specifications in accordance with standard operating procedures.
   • Where required, appropriate solvent and solvent application are selected to meet job specification.
   • Where required, appropriate mechanical equipment is selected to meet job specification.
   • Work site is prepared for surface cleaning activities.
2. Set up equipment
   • Appropriate equipment and any required consumables are assembled, set up and prepared correctly and safely in accordance with manufactures' specifications and standard operating procedures.
3. Prepare surfaces using solvents as required
   • Safe working environment for solvent use is established according to regulatory requirements and standard operating procedures.
   • Solvents are applied correctly.
   • Treated surface is neutralised and made safe to handle.
4. Prepare surfaces using mechanical means as required
   • Safe working environment for mechanical surface preparation is established according to regulatory requirements and standard operating procedures.
   • Surfaces are prepared using mechanical means.
   • Mechanical equipment is cleaned and checked for damage and operational faults, in accordance with standard operating procedures.
   • Equipment faults are recorded and reported in accordance with standard operating procedures.
5. Inspect prepared surface
   • Surface preparation is checked for cleanliness and conformance to specifications.
   • Faults or defects are rectified where required and recorded/reported in accordance with standard operating procedures.

Required Skills

Required skills

Look for evidence that confirms skills in planning and sequencing operations preparing surfaces using solvents as required preparing surfaces using mechanical means setting up equipment and consumables meeting all safety requirements using solvents correctly neutralising solvents using mechanical equipment to prepare surface maintaining mechanical equipment recording and reporting of faults inspecting prepared surface rectifying work performed checking for conformance to specifications reading and interpreting routine information on written job instructions specifications and standard operating procedures following oral instructions applying measurement skills needed to meet the requirements of this unit entering routine and familiar information onto proformas and standard workplace forms

Required knowledge

Look for evidence that confirms knowledge of common surface contaminates conditions reasons for selecting solvents mechanical equipment required procedure for setting up equipment specifications applying to the surface to be prepared methods for neutralising solvents tools equipment abrasives and other materials procedures for maintainingstoring mechanical equipment procedures for recordingreporting faulty equipment procedures checking prepared surfaces rectification techniques use and application of personal protective equipment safe work practices and procedures relevant hazards and control measures related to the competency

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	A person who demonstrates competency in this unit must be able to select the appropriate preparation process select and set up the equipment undertake mechanical preparation or application of solvents as required and inspect the finished surface Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	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
Context of and specific resources for assessment	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 surface preparation using solvents andor mechanical means or other units requiring the exercise of the skills and knowledge covered by this unit
Method of 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

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.
Surface preparation	New surfaces and restoration work
Solvents	A range of cleaning chemicals including acids, chlorinated solvents and hydrocarbons
Solvent application methods	Spraying, wiping, brushing, vapour degreasing etc.
Mechanical equipment	Linishers, grinders, polishers, sanders, blast device, enclosures, air grinders etc.
Consumables	Emery cloth/belts, grinding/sanding disks, grinding accessories etc.
