Repair glass apparatus using simple glassblowing equipment
Application
This unit of competency is applicable to scientific glassblowers. It covers work that will sometimes be performed by less experienced workers under the guidance of an experienced scientific glassblower. Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These are found at the end of this unit of competency under the section 'This competency in practice'. |

Required Skills
|
Required skills |
Required skills include: determining types of contaminants present on/in apparatus cleaning techniques for contamination carried out before repair operations are undertaken using appropriate treatment processes, with particular attention to risks associated with blowing used and possibly contaminated glass reading and following blueprints, drawings, sketches and designs relevant to repair work selecting appropriate grades of glass and preparing for use preparing apparatus for repair optimising and using glassblowing equipment identifying atypical or out of normal repair problems reporting problems to either supervisor or outside service technician according to enterprise procedures recording and communicating work results following correct occupational health and safety (OHS) and principles of good laboratory practice (GLP) |
Required knowledge |
Required knowledge includes: relevant glassblowing techniques the risks associated with blowing used and contaminated glass contamination cleaning techniques to be carried out before repair operations are undertaken use and function of the broken apparatus repair materials and reason for their choice use of appropriate tools and equipment basic chemical and physical concepts related to behaviour of glass under heat and stress basic knowledge of how apparatus to be repaired is used critical material properties and appropriate glassworking parameters pre-repair apparatus preparation procedures annealing procedures methods of minimising potential quality problems relevant health, safety and environment requirements |
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 | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors should ensure that candidates can: safely repair glass apparatus following enterprise procedures assess the economics of salvage follow a procedure of disassembly/assembly of apparatus in accordance with specifications apply contamination cleaning techniques before repair operations are undertaken report problems to appropriate personnel. |
Context of and specific resources for assessment | This unit of competency is to be assessed in the workplace or simulated workplace environment. This unit of competency may be assessed with: MSL963001A Operate basic handblowing equipment. Resources may include: access to a scientific glassblowing facility, appropriate equipment, materials and procedures a bank of case studies where these form part of the assessment method. |
Method of assessment | It is strongly recommended that assessment is conducted through observation over time. The timeframe must allow for adequate assessment of operation under all normal and a range of abnormal conditions. Where this is not practical additional assessment techniques must be used. The following assessment methods are suggested: inspection of glasswork and workplace documentation completed by the candidate analysis of work completed over a period of time to ensure accurate and consistent work is obtained within required timelines. feedback from peers and supervisors use of suitable simulation and/or a range of case studies/scenarios. In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. 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. The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment. |
This competency in practice | Industry representatives have provided the case study below to illustrate the practical application of this unit of competency and show its relevance in a workplace setting. Education A trainee glassblower has been asked by his/her supervisor to repair several pieces of used and broken laboratory glassware as part of a cost saving exercise. Firstly, he/she determines whether the glassware will be used for general tasks or for qualitative analysis and how urgently the job is required. He/she then clarifies whether any hazardous material has been used in the equipment and applies the correct cleaning procedures. After determining the nature of the glass and the appropriate glassworking parameters, he/she repairs the equipment using safe apparatus. Finally the glassblower subjects the equipment to the appropriate annealing/conditioning process and checks the final outcome with his/her supervisor. Any contaminated or used glass waste is disposed of appropriately. |
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. | |
Codes of practice | Where reference is made to industry codes of practice, and/or Australian/international standards, it is expected the latest version will be used |
Standards, codes, procedures and/or enterprise requirements | Standards, codes, procedures and/or enterprise requirements may include: calibration and maintenance schedules enterprise recording and reporting procedures equipment manuals equipment startup, operation and shutdown procedures industry codes of practice material safety data sheets (MSDS) material, production and product specifications national environment protection measures OHS national standards and codes of practice production and laboratory schedules quality manuals standard operating procedures (SOPs) |
Tools, materials and equipment | Tools, materials and equipment may include: burners, gas supplies and gas economisers glassworking lathes mechanical glass cutters and saws mechanical glass grinding equipment annealing ovens measuring and recording equipment hand tools, such as carbon paddles and mandrels, range of forceps, glass tubing gauges, angle setting jigs, calipers, glass support rollers, brass shapers, carbon rods, glass knife, stainless steel gauze, vernier calipers and other measuring tools, and strain viewer various glass types, including soda-lime, borosilicate, quartz, silica and special formula glasses glass to metal seals communication equipment |
Hazards | Hazards may include: sharps and broken glassware heat sources, such as burners and ovens fluids under pressure (acetylene and oxygen) glass dust cuts associated with glass grinders and cutters manual handling of heavy sample bags and containers |
Safe work practices | Safe work practices may include: use of personal protective equipment, such as heat resistant gloves, safety glasses, goggles, face guards, coveralls, respirators and safety boots correct labelling of reagents and hazardous materials handling, and storing hazardous materials and equipment in accordance with labels, MSDS, manufacturer's instructions, and enterprise procedures and regulations regular cleaning and/or decontamination of equipment and work areas |
Occupational health and safety (OHS) and environmental management requirements | OHS and environmental management requirements: all operations must comply with enterprise OHS and environmental management requirements, which may be imposed through state/territory or federal legislation - these requirements must not be compromised at any time all operations assume the potentially hazardous nature of samples and require standard precautions to be applied where relevant, users should access and apply current industry understanding of infection control issued by the National Health and Medical Research Council (NHMRC) and State and Territory Departments of Health |
