Unit Descriptor

Unit descriptor 

This unit of competency covers the ability to participate in laboratory investigations involving animals, plants and related environmental parameters. The animals or plants might be single specimens, parts of specimens or be in culture or under propagation. The investigations might also be part of experimental models that examine interactions of animals and/or plants and their environments. Investigations would generally relate to taxonomy, physiology and pathology, and would be oriented to scientific research, food production and manufacture, and to investigation of biological environments and ecosystems.

Application of the Unit

Application of the unit 

This unit of competency is applicable to laboratory technicians and technical officers working in biological, biotechnology and environmental industry sectors. It is expected that all work would conform to statutory and enterprise occupational health and safety (OHS) codes of practice. This unit of competency assumes that the worker would perform tests and procedures under the close supervision of scientific staff and that the enterprise will equip its workers with relevant animal handling skills should such be required. The unit does not cover procedures related to the handling of vertebrates that are subject to national and state/territory animal care and ethics regulations.

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 can be found at the end of this unit of competency under the section 'This competency in practice'.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors should ensure that candidates can:

  • relate field and laboratory data for the generation of meaningful results
  • identify and classify animal and plantspecies for scientific and experimental purposes
  • maintain the viability of species during experimentation
  • monitor the physiology and interactions of plants and animals and their environments
  • take representative samples for analysis
  • work safely for the protection of self and co-workers
  • communicate appropriately with customers and be aware of cultural and social contexts
  • not contaminate sterile environments or specimens
  • dispose of wastes carefully for the protection of those who may handle and process wastes and to minimise contamination of the environment.

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:

  • MSL925001A Analyse data and report results 
  • MSL974007AUndertake environmental field -based monitoring .

Resources may include:

  • equipment and resources for investigating the physiology of plants and animals in the laboratory
  • enterprise procedures, sampling plans, test methods and equipment manuals
  • computers and programs for simulated experiments or data analysis.

Method of assessment 

The following assessment methods are suggested:

  • review of data/results obtained by the candidate over time to ensure accuracy, consistency and timeliness of results
  • inspection of records and workplace documentation completed by the candidate
  • observation of the candidate processing specimens and/or conducting analyses
  • review of computer and literature research of data to support an experiment
  • questioning about procedures that form part of experiments in progress
  • review of case studies prepared by the candidate, such as:
  • relating field and laboratory data in an environmental impact statement
  • preservation of plant species and placement in a herbarium
  • plant propagation in a variety of controlled environments
  • maintenance of cultures of protozoans or invertebrates.

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 studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Environmental  ()

A technical officer has been asked to preserve plant specimens and compile a report of classified species using material and data collected during a recent visit to a decommissioned open cut mine site and its adjacent areas. The supervising ecologist has been asked to advise the mine owner about replacement planting to restore the mine site in sympathy with its locality. The technical officer records descriptions of features of each specimen. They use this data to classify the species by referring to the field report, atlases and specimens in the reference herbarium. They then prepare each specimen for drying and preservation in readiness for labelling and cataloguing. To compile the report, the technical officer prepares a map of the area to be regenerated. The map details the topographic features and illustrates possible species which could be planted. To assist the landscape contractors, the technical officer advises where the required species can be purchased and the type of soils required for growth.

Environmental  ()

A technical officer, who worked for a large aluminium smelter, was asked to examine some grapevine leaves that a local farmer argued were affected by fluoride emissions from the plant. Initially, the leaves were subjected to a detailed microscopic examination using standard procedures developed by the company covering the effect of gaseous pollutants (such as ozone and fluoride) on major natural and/or agricultural plants. The preliminary findings suggested that the leaves were affected by a fungi rather than fluoride. However, given the sensitive nature of the issue, they checked with the supervisor and arranged to send the affected leaves to a nearby university for a second opinion. This additional study also concluded that the impact on the leaves was not due to fluoride.
