3.4. Materials and consumable stores are cleaned and restored in accordance with site, industry and regulatory standards

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

• collect, organise and understand information related to spray systems and equipment, maintenance materials, 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 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 estimate material requirements
• use pre-checking and inspection techniques to anticipate maintenance problems, avoid reworking and avoid wastage
• use the limited workplace technology related to maintenance, including machines, tools, equipment, and measuring devices

Required knowledge 

• identification of spray system equipment, processes and procedures
• the types, characteristics and maintenance requirements for spray booth services, including at a minimum ventilation, lighting, water and electrical reticulation
• characteristics of the coatings and base materials in terms of toxicity, reactivity and flammability
• types, characteristics, uses and limitations of cleaning solvents and agents
• effects of the fumes, heat and other radiations on surface coatings
• material safety management systems

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 

• Locate, interpret and apply information relevant to the spray equipment and booth services
• 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, equipment or products
• maintain required standards and quality

• Disassemble, maintain and reassemble at least two different spray systems
• Maintain a booth and booth services on at least two occasions
• Work effectively with others
• Modify activities to cater for variations in workplace contexts and environment.

Resource Implications 

Spray systems and equipment, spray booth, cleaning and maintenance materials.

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 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.
