2. Check and prepare for spraying

2.1. Products with surface or other faults are identified and faults reported or repaired as appropriate

2.2. Other products and equipment in the workplace are protected from overspray

2.3. Trial applications of surface materials are made to check condition of spray system, spray patterns, equipment operation, materials viscosity and specified surface finish

2.4. Unserviceable components are cleaned or replaced and spray system reassembled

2.5. Spray pattern faults are identified and rectified in accordance with workplace procedures.

2.6. Material faults are identified and workplace procedures for rectification are followed

3. Apply surface coating

3.1. Surfaces are kept free of contamination

3.2. Surface coatings are applied according to workplace procedures

3.3. Surface build and coverage is checked against workplace requirements for even spread and thickness

3.4. Rectification of surface faults are made in accordance with workplace procedures

3.5. Products are inspected and approved for suitability for further processing

4. Clean work area and maintain equipment

4.1. Equipment is cleaned and inspected for serviceable condition and stored appropriately

4.2. Unserviceable equipment is tagged, faults are identified and appropriate personnel are informed

4.3. Work area, including spray booth is cleaned and returned to approved condition

4.4. Workplace records are completed

Required skills

collect, organise and understand information related to spray equipment and painting materials, work orders, basic 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 back tracking, 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 coating problems, avoid re-working and wastage

use the workplace technology related to spraying operations including tools, equipment and measuring devices

Required knowledge

identification of spray 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

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

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 spray pattern for a minimum of three different surface types and shapes

Maintain spray equipment and work area, including spray booth

Work effectively with others

Modify activities to cater for variations in workplace contexts and environment

Resource Implications

Spray 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.

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.

Unit context

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