Description
This unit covers selecting the appropriate preparation process, selecting and setting up the equipment, undertaking blasting or application of solvents as required, and checking the finished surface.
Notes
Elements and Performance Criteria
1. Determine job requirements
- 1.1. Surface preparation requirements are determined from job sheet, instructions or other predetermined specifications in accordance with standard operating procedures.
- 1.2. Where required, appropriate solvent and solvent application are selected to meet job specification.
- 1.3. Where required, appropriate mechanical equipment is selected to meet job specification.
- 1.4. Work site is prepared for surface cleaning activities.
2. Set up equipment
- 2.1. 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
- 3.1. Safe working environment for solvent use is established according to regulatory requirements and standard operating procedures.
- 3.2. Solvents are applied correctly.
- 3.3. Treated surface is neutralised and made safe to handle.
4. Prepare surfaces using mechanical means as required
- 4.1. Safe working environment for mechanical surface preparation is established according to regulatory requirements and standard operating procedures.
- 4.2. Surfaces are prepared using mechanical means.
- 4.3. Mechanical equipment is cleaned and checked for damage and operational faults, in accordance with standard operating procedures.
- 4.4. Equipment faults are recorded and reported in accordance with standard operating procedures.
5. Inspect prepared surface
- 5.1. Surface preparation is checked for cleanliness and conformance to specifications.
- 5.2. Faults or defects are rectified where required and recorded/reported in accordance with standard operating procedures.
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.

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
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 and/or 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, 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.
