Range Statement
The range of variables relates to the unit of competency as a whole. It allows for different work environments and situations that will affect performance.
Where reference is made to industry Codes of Practice, and/or Australian/international standards, it is expected the latest version will be used.This unit of competency describes the work conducted by laboratory technicians who prepare, standardise and use solutions and monitor the quality of the prepared solutions.All operations must comply with relevant standards, appropriate procedures and/or enterprise requirements. These procedures may include or have been prepared from:Australian and international standards, such as:AS ISO/IEC 17025 General requirements for the competence of testing and calibration laboratoriesISO 9000 series Quality management and quality assurance standardsAS 2243 Safety in laboratoriesAS 2830 Good laboratory practiceCodes of Practice, such as GLP and GMPmaterial safety data sheets (MSDSs)National Measurement Actstandard operating procedures (SOPs)quality manuals, equipment and procedure manualsenterprise and reporting proceduresproduction and laboratory schedulesmaterial, production, product and solution specificationswaste minimisation and safe disposal procedures.Solutions may include but are not limited to:solutions of strong/weak acids and bases oxidising/reducing agents solutions used for complexometric or precipitation titrations stains for cells and tissues, enzymes, buffers and antibodiesdiluents for maintaining isotonicityorganic solutions and histological fixatives.Apparatus and reagents which may be used to prepare standard solutions include:balances pipettes, burettes, volumetric glassware, weighing bottles dessicators, filtering media ovens, muffle furnaces solutions, indicators, primary and secondary standards auto titrators, pH meters and other related meters and electrodes for determining equivalence points, top pan and analytical balances magnetic stirrers and heaters, water baths.Checking useability of solutions could include:examining stained samples for correct staining reactionsperforming pH checksconfirming enzyme activitychecking red cell suspensions for haemolysis.Hazards may include:chemicals, such as strong acids and bases, stainssharps, broken glasswareburners, hot plates, ovens, furnaces.Safe work practices may include:use of material safety data sheets (MSDSs)use of personal protective equipment, such as gloves, safety glasses, goggles, faceguards, coveralls, gownuse of biohazard containers, laminar flow cabinets, fumehoodscorrect labelling of reagents and hazardous materialshandling and storing hazardous materials and equipment in accordance with labels, MSDS, manufacturer's instructions, enterprise procedures and regulationsregular cleaning and/or decontaminating of equipment and work areas.Health, safety and environmentAll operations to which this unit applies are subject to stringent health, safety and environmental (HSE) requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence.All operations assume the potential hazardous nature of samples and require standard precautions to be applied. Users should access and apply current industry understanding of infection control issued by the National Health and Medical Research Council and State and Territory Departments of Health. All operations are performed in accordance with standard operating procedures.
