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: Australian and international standards, such as: AS ISO 1000-1998 The international system of units (SI) and its application AS ISO 17025-2005 General requirements for the competence of testing and calibration laboratories AS/NZS ISO 14000 Set:2005 Environmental management standards set AS/NZS ISO 9000 Set:2008 Quality management systems set enterprise procedures for specific client measurements at particular sites enterprise recording and reporting procedures equipment manuals equipment startup, operation and shutdown procedures maps and site plans material safety data sheets (MSDS) and safety procedures material, production and product specifications national measurement regulations and guidelines occupational health and safety (OHS) national standards and codes of practice standard operating procedures (SOPs) |
Concepts of metrology | Concepts of metrology may include: that all measurements are estimates measurements belong to a population of measurements of the measured parameters repeatability precision accuracy significant figures sources of error uncertainty traceability |
Hazards | Hazards may include: solar radiation, dust and noise wildlife, such as snakes, spiders and domestic animals biohazards, such as micro-organisms and agents associated with soil, air and water chemicals, such as acids and hydrocarbons manual/handling of heavy equipment or materials crushing, entanglement and cuts associated with moving machinery falling objects, uneven surfaces, heights, slopes, wet surfaces, trenches and confined spaces vehicle handling in rough terrain and boat handling in rough or flowing water vehicular or pedestrian traffic |
Safety practices | Safety practices may include: use of MSDS use personal protective equipment, such as hard hats, hearing protection, gloves, safety glasses, goggles, face-guards, coveralls, gowns, body suits, respirators and safety boots correct labelling of hazardous materials handling and storing hazardous material and equipment in accordance with labels, MSDS, manufacturer's instructions, enterprise procedures and regulations regular cleaning and/or decontaminating of equipment machinery guards signage, barriers, service isolation tags, traffic control, flashing lights lockout and tag-out procedures |
Measurements | Measurements could include the use of instruments and/or kits to test: pH, specific ions, such as iron in water using dipsticks dissolved oxygen (DO) electrical conductivity (EC) |
Other measurements | Other measurements may include: sound (e.g. dB level and dBA) light levels and illumination basic production/process parameters (e.g. flow, temperature, pressure, mass and depth) simple surveys (e.g. number of trees in quadrant) background radiation (e.g. Geiger counter) dimensions meteorological measurements (e.g. temperature, rainfall and wind) |
Common measuring equipment | Common measuring equipment may include: tape measure, rulers, micrometers callipers and water level indicators balances meter/probe systems (e.g. DO and EC) analogue and digital meters (e.g. voltage, current, resistance, pressure, temperature, barometers, anemometers and hygrometers) dipsticks or spot test kits clocks and timing devices |
Services | Services may include: water supply, gas and electricity telecommunications irrigation, stormwater, drainage and sewerage systems production plant |
Appropriate corrective actions | Appropriate corrective actions may include: logical check of equipment setup check of calibration, zero error and drift for basic instruments careful re-reading of procedures repeat measurements seek advice |
Minimising environmental impacts | Minimising environmental impacts may involve: disposal of surplus, spent or purged materials recycling of wastes responsible driving to avoid damage to vegetation and fauna cleaning of vehicles to prevent transfer of pests and contaminants |
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 |
