Required Skills
Required skills |
Required skills include: handling cleaned components handling chemicals safely operating cleaning machines mixing chemicals and solutions handling cleaned components to prevent contamination storing cleaned components to maintain finish |
Required knowledge |
Required knowledge includes: cleaning solutions and uses cleaning procedures for different components and finishes watch case cleaning methods (ultrasonic, vibrationary) cleaning machine types, uses, function and operation potential for damage to components by chemicals or cleaning operations chemical storage and disposal OHS regulations and procedures |
Evidence Required
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 clean watch and clock components to industry standards, manufacturer specifications and in accordance with safety regulations and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently: prepare solutions and equipment work safely with chemicals and equipment sort and track components during process clean components without damage verify components as effectively cleaned. |
Context of and specific resources for assessment | Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and information on workplace practices and OHS practices. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability. Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities. |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge. Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application. Assessment may be applied under project-related conditions (real or simulated) and require evidence of process. Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances. Assessment may be in conjunction with assessment of other units of competency where required. |
Guidance information for assessment | Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed. |
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. | |
Personal protective equipment | Personal protective equipment may include: protective masks gloves for handling chemicals fire blankets and extinguishers ventilation of cleaning area clothing (e.g. dustcoats and aprons) |
Emergency response procedures | Emergency response procedures may include: safe selection and use of fire extinguishers use of safety blankets and other methods of suppressing solvent-based fires emergency treatment of eye splashes and chemical burns carcinogenic effects of chemical inhalation and absorption |
Cleaning methods, processes and equipment | Cleaning methods, processes and equipment may include: mechanical processes (e.g. rotational and vibrational) electronic (e.g. ultrasonic) steam cleaning cleaning machines cleaning baskets hand cleaning (e.g. with pith, brushes and peg wood) |
Cleaning solutions | Cleaning solutions may include: number 1 degreasing and cleaning solution (WF1) customised solutions, ammonia, oleic acid, acetone and water-based solutions commercial grade ammonia concentrates rinsing solutions, including hydrocarbon solvents (e.g. Shellite, Mobil B1 and X55) |
