Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Prepare for surface coating removal	1.1. Materials safety data sheets and/or product application and safety information are read and used to inform work practices 1.2. OHS requirements, including ventilation requirements and personal protection needs, are observed throughout the work 1.3. Surface coating is tested to identify the type of material and methods required remove the coating 1.4. Tools, equipment and materials suitable for the removal tasks are selected and checked for safe operation/application 1.5. Accessories and consumables are identified for the removal tasks
2. Remove surface coatings	2.1. Sequence of work is identified, maximising potential of any chemical for the removal operation 2.2. Equipment, chemicals and abrasives are used within manufacturer specifications and workplace procedures 2.3. Surface coating is removed according to workplace procedures and specifications 2.4. Surfaces are inspected to ensure removal of surface coating is to workplace standard 2.5. Defects found after removal of surface coating are dealt with and/or reported in accordance with workplace procedures
3. Clean work area and maintain equipment	3.1. Item is stored and labelled ready for next process 3.2. Equipment is cleaned and inspected for serviceable condition and stored appropriately 3.3. Unserviceable equipment is tagged, faults are identified and appropriate personnel are informed 3.4. Chemicals and other materials are stored or disposed of correctly according to regulations 3.5. Work area is cleaned ready for next process or task

Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE
This section describes the skills and knowledge required for this unit.
Required skills
collect, organise and understand information related to hardware identification and selection, work orders, plans and safety procedures communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems plan and organise activities, including the preparation and layout of the worksite and the obtaining of equipment and materials to avoid any backtracking, workflow interruptions or wastage work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements use pre-checking and inspection techniques to anticipate removal problems, avoid reworking and avoid wastage use the limited workplace technology related to the selection and application, including hardware options, tools, equipment and measuring devices
Required knowledge
workflow in relation to the removal of surface coatings the types, properties and characteristics of coatings coating removal techniques, materials, applications and limitations material safety management systems

Evidence Guide

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.
Critical Aspects of Evidence	Interpret work order and locate relevant information Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment Follow work instructions, operating procedures and inspection practices to: minimise the risk of injury to self or others prevent damage to goods, tools, equipment or products maintain required production output and product quality Remove surface coating from timber and metal surfaces, and apply appropriate techniques to remove coatings from flat, vertical, carved and curved surfaces, using a minimum of four different removal techniques and materials Work effectively with others Modify activities to cater for variations in workplace contexts
Resource Implications	Range of surfaces to be removed, removal methods, tools, equipment and consumables.
Method of Assessment	Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts. Assessment should be by direct observation of tasks and questioning on underpinning knowledge. Assessment should be conducted over time and may be in conjunction with assessment of other units of competency.
Context of Assessment	Assessment may occur on the job or in a workplace simulated facility with relevant process equipment, materials, work instructions and deadlines.

Range Statement

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.
