Elements and Performance Criteria

The Range Statement provides advice to interpret the scope and context of this unit of competency, allowing for differences between enterprises and workplaces. It relates to the unit as a whole and facilitates holistic assessment. The following variables may be present for this particular unit:

Surface coating operations

This unit covers work involved in the application of surface coatings by mechanical methods other than by conventional hand-held spray gun or airless spray gun

Surface coatings are to include: a minimum of two of those required for curtain coating, UV coating, tumbling, dipping and electrostatic powder coating tasks

Unit context

OH&S requirements include legislation, building codes, material safety management systems, hazardous substances and dangerous goods code and local safe operating procedures

Work is carried out in accordance with legislative obligations, environmental legislation, relevant health regulations, manual handling procedures and organisation insurance requirements

Work requires individuals to demonstrate discretion, judgement and problem solving skills in the application of surface coatings

Tools and equipment are to include:

computerised spray system

electrostatic spray gun

baking oven

barrel tumbler

spray booth

liquid containers

air compressor and hoses

screwdrivers

shifting spanner and spanners

ford cup

Materials to be applied may include but are not limited to:

stains

lacquers

wax

oil

two-pack polyurethane

three-pack polyester

enamels

acrylics

powder coating

Personal protective equipment

Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices

Information and procedures

Workplace procedures relating to the use of tools and equipment

Work instructions, including job sheets, plans, drawings and designs

Workplace procedures relating to reporting and communication

Manufacturers' specifications and operational procedures

The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competency for this unit. This is an integral part of the assessment of competency and should be read in conjunction with the Range Statement.
Critical Aspects of Evidence
Locate, interpret and apply information relevant to the materials being applied and the application equipment
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 and others
prevent damage to goods, equipment and products
maintain required production output and product quality
Select and apply surface coatings, including the adjustment of spray equipment to effect required coating using a minimum of two different mechanical systems:
curtain coater
electrostatic
tumbler
dipping
roller coater (UV)
automatic (robotic) spray equipment
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment

Underpinning Knowledge
Identification of mechanical spray system equipment, processes and procedures
Characteristics of the coatings and base materials in terms of toxicity, reactivity, flammability, required viscosity and recoatability
Effects of the fumes, heat and other radiations on surface coatings
The methods to prevent contamination of surfaces during and after surface coating
Workflow in relation to spraying operations

Underpinning Skills
Information. Collect, organise and understand information related to coating system and machines, coating materials, work orders, plans and safety procedures
Communication. Communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the notification of work outcomes and problems
Planning. Plan and organise activities, including the preparation and layout of the worksite and the obtaining of equipment and materials to avoid any back tracking, workflow interruptions or wastage
Teamwork. Work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
Mathematical ideas and techniques. Use mathematical ideas and techniques to correctly complete measurements and estimate paint requirements and other material requirements
Solve problems. Use pre-checking and inspection techniques to anticipate coating problems, avoid reworking and avoid wastage
Use of technology. Use workplace technology related to mechanical coating systems, including machines, tools, equipment and measuring devices

Resource Implications
Mechanical spray systems and equipment, spray booth, coatings and cleaning products.

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 may be in conjunction with assessment of other relevant 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.

Key Competency Levels
NB:These levels do not relate to the Australian Qualifications Framework. They relate to the seven areas of generic competency that underpin effective workplace practices.
There are three levels available:
Level 1 where work is within set conditions and process
Level 2 where the management or facilitation of conditions or process is exercised; and
Level 3 where the design and/or development of conditions or process is required
