Description
This unit of competency covers the ability to assist air quality scientists and engineers with assessing odour emissions from sites and the effectiveness of odour abatement systems. Personnel use site sampling and monitoring plans, workplace procedures and/or standardised methods to collect odour samples and conduct olfactometry measurements using panellists in the laboratory. This unit of competency is applicable to environmental technicians working in a range of industry sectors, such as environmental services (e.g. sampling and monitoring of air, odours and air quality consultancy); environmental compliance, auditing and inspection; chemical, food and by-product process manufacturing; solid waste management; water treatment and wastewater management; agricultural/livestock activities; landfill operations and rendering operations.While no specific licensing or certification requirements apply to this unit at the time of publication, environmental monitoring and management activities are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked.
Notes
Elements and Performance Criteria
1 Clarify site monitoring requirements with supervisor
  • 1.1 Examine available information about the site’s history, current activities/processes, previous odour assessments, topography, prevalent meteorological conditions and complaint records.
  • 1.2 Visit the site with supervisor to clarify issues with the proponent and community representatives, as appropriate.
  • 1.3 Collect and review information about site process operations and conditions.
  • 1.4 Identify potential odour sources at the site and current controls.
  • 1.5 Review relevant legislative, regulatory and licensing requirements or workplace procedures/test methods.
2 Prepare for source monitoring
  • 2.1 Select, or design, appropriate sampling and monitoring strategies in consultation with supervisor.
  • 2.2 Confirm details of relevant odour sampling/monitoring plans, need for site permits and access to the site.
  • 2.3 Confirm data format and quality requirements.
  • 2.4 Review relevant standards and/or specified workplace procedures/test methods.
  • 2.5 Assemble required sampling and monitoring equipment and check that all reusable items are clean, fit for purpose and calibrated correctly.
  • 2.6 Ensure that all required supplies and equipment are transported safely to and from the site.
3 Prepare standardised or in-house odour panellists
  • 3.1 Confirm the specifications for panellists with supervisor and client, as necessary.
  • 3.2 Conduct standardised selection to determine odour threshold and ongoing olfactometry performance of individuals.
  • 3.3 Conduct standardised or in-house selection to assess and compare sensitivity against internal criteria.
  • 3.4 Select panellists in consultation with supervisor.
  • 3.5 Train selected panellists in the use of objective odour observation techniques, odour descriptors, olfactometry procedures and test equipment.
  • 3.6 Record the process and results used to establish and maintain a register of reliable panellists.
4 Collect and store odour samples for source monitoring
  • 4.1 Check that process/meteorological conditions are consistent with sampling design conditions and report any deviations.
  • 4.2 Set up sampling equipment and conduct pre-use checks to ensure reliable operation.
  • 4.3 Collect samples in accordance with standard methods or workplace procedures.
  • 4.4 Store samples for subsequent analysis to ensure their ongoing integrity and traceability.
  • 4.5 Identify and report any defects or abnormalities in samples.
  • 4.6 Record all sample information in accordance with standard methods or workplace procedures.
5 Conduct laboratory olfactometry measurements
  • 5.1 Set up dynamic olfactometer and related equipment and conduct pre-use checks to ensure reliable operation.
  • 5.2 Ensure that panellists fully understand the test procedures.
  • 5.3 Conduct tests in accordance with standard method.
  • 5.4 Monitor panellist’s performance for indications of odour fatigue, adaption of their senses to the surrounding ambient air and/or bias.
  • 5.5 Analyse the conduct of the measurements and reliability of results before confirming data acceptability.
6 Maintain a safe work environment
  • 6.1 Ensure safety through the use of specified safety equipment, safe work procedures and personal protective clothing.
  • 6.2 Handle all samples and equipment in accordance with workplace safety procedures.
  • 6.3 Minimise generation of waste and environmental impacts.
  • 6.4 Collect and dispose of all wastes safely.
  • 6.5 Report hazards and incidents to designated personnel using workplace procedures.
7 Record data and report results
  • 7.1 Record details of the testing process and data in accordance with standard method or workplace procedures.
  • 7.2 Process data and report results in accordance with standard method or workplace procedures.
  • 7.3 Record approved data in accordance with specified format and quality requirements.
  • 7.4 Maintain confidentiality and security of workplace information and data.
