Elements and Performance Criteria

  1. Prepare for measurements

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Standards, codes, procedures and/or workplace requirements

Standards, codes, procedures and/or workplace requirements include the latest version of one or more of:

Australian and international standards covering the requirements for the competence of testing and calibration laboratories, laboratory safety, quality management and environmental management

national work health and safety (WHS) standards and codes of practice, national environmental protection measures, and national measurement regulations and guidelines

specific codes, guidelines and procedures, such as National Association of Testing Authorities (NATA) accreditation requirements and principles of good laboratory practice (GLP)

workplace documents, such as standard operating procedures (SOPs); quality and equipment manuals; calibration and maintenance schedules; material safety data sheets (MSDS); safety procedures; material, production and product specifications; production and laboratory schedules; workplace recording and reporting procedures; waste minimisation and safe disposal procedures; and maps and site plans

measurement procedures for specific sites and clients

Direct measurements

Direct measurements role include, but are not limited to, one or more of:

basic production/process parameters (e.g. flow, temperature, pressure, mass and depth, and dimensions)

simple surveys (e.g. number of trees in quadrant)

meteorological measurements (e.g. temperature, rainfall and wind)

sound (e.g. dB level and dBA)

light levels and illumination

background radiation (e.g. Geiger counter)

chemical tests using simple instruments and/or kits to test pH, specific ions, such as iron in water using dipsticks, dissolved oxygen (DO) and electrical conductivity (EC)

Measuring equipment

Measuring equipment includes, but is not limited to, one or more of:

tape measures, rulers, micrometers, Vernier callipers and water level indicators

balances

meter/probe systems, such as DO and EC

analogue and digital meters, such as voltage, current, resistance, pressure, temperature, barometers, anemometers and hygrometers

dipsticks and spot test kits

clocks and timing devices

Services

Services include one or more of:

water supply, gas and electricity

telecommunications

irrigation, stormwater and drainage systems

production plant

Safety procedures

Safety procedures include, but are not limited to, one or more of:

use of PPE

handling, labelling and storing hazardous material and equipment in accordance with labels, MSDS, manufacturer instructions, and workplace procedures and regulations

regular cleaning and/or decontamination of equipment

use of machinery guards

signage, barriers, service isolation tags, traffic control and flashing lights, and lockout and tag out procedures

Minimising environmental impacts

Minimising environmental impacts includes, but is not limited to, one or more of:

appropriate disposal of surplus, spent or purged materials and hazardous waste

recycling of non-hazardous wastes

driving vehicles to minimise soil erosion and damage to fauna and vegetation

cleaning of vehicles and equipment to prevent transfer of pests and contaminants

WHS and environmental management requirements

WHS and environmental management requirements include:

· complying with WHS and environmental management requirements at all times, which may be imposed through state/territory or federal legislation. These requirements must not be compromised at any time

· applying standard precautions relating to the potentially hazardous nature of samples

accessing and applying current industry understanding of infection control issued by the National Health and Medical Research Council (NHMRC) and State and Territory Departments of Health, where relevant

Performance Evidence

Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:

safely making a variety of direct measurements at different sites on at least three (3) occasions

liaising with others to access sites and perform measurements efficiently

correctly locating measurement points and services at sites

making measurements to minimise environmental impact and/or disruption to normal site operations

safely operating instruments and test kits in accordance with workplace procedures and manufacturer instructions

reading scales/displays accurately and taking sufficient measurements to ensure reliable data

recording data that is legible, free of errors and has appropriate accuracy, precision and units

recognising obvious errors/atypical data and using corrective actions, including:

logical check of equipment set-up

check of calibration, zero error and drift for basic instruments

careful re-reading of procedures

repeating measurements

seeking advice

maintaining confidentiality and reporting problems and incidents in accordance with procedures

following workplace procedures for safely conducting site measurements; recording and reporting data and any relevant legal traceability requirements; and maintenance, storage and transport of measurement equipment

recognising own limitations and seeking timely advice.

Knowledge Evidence

Must provide evidence that demonstrates knowledge of:

concepts of metrology, including:

all measurements are estimates

measurements belong to a population of measurements of the measured parameters

precision, accuracy and significant figures

sources of error, uncertainty and repeatability

traceability

international system of units (SI)

purpose of measurements performed as part of job role and the principles of operation for the equipment/instruments used

sources of uncertainty in measurement and methods for control

workplace safety procedures associated with measurements undertaken as part of job role; the maintenance, storage and transport of measurement equipment; waste management and handling of dangerous goods

workplace and/or legal traceability requirements

procedures for recognising and reporting of unexpected or unusual results

relevant hazards, work health safety (WHS) and environment requirements.
