Overview of assessment 

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

Assessors should ensure that candidates can:

  • collect the specified quantity of sample to enable all processing and testing to occur and back-up samples to be stored
  • obtain a sample that is representative of the bulk material
  • preserve the integrity of samples by closely adhering to procedures
  • label samples and sub-samples to satisfy enterprise/legal traceability requirements
  • identify atypical materials and samples and take appropriate action
  • maintain sampling equipment in appropriate condition
  • complete sampling records using enterprise procedures
  • follow safety regulations and enterprise OHS procedures during sampling, transport and storage
  • follow relevant legislative requirements for the disposal of waste and the preservation 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:

  • MSL924001A Process and interpret data 
  • MSL943002A Participate in laboratory /field workplace safety 
  • relevant MSAL974000 series units of competency 
  • relevant MSAL975000 series units of competency relevant to the sampling .

Resources may include:

  • variety of sample types
  • sampling plans
  • a selection of sampling containers and sampling equipment.

Method of assessment 

The following assessment methods are suggested:

  • inspection of samples collected by the candidate
  • review of sampling documentation completed by the candidate
  • feedback from peers, customers and supervisors that sampling plans were followed
  • questioning to assess underpinning knowledge of representative sampling procedures
  • observation of the candidate taking a range of samples.

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.

Manufacturing 

A metallurgical laboratory technician is very familiar with preparing representative samples for a range of final products in a steelmaking plant. One day, he/she is asked to sample a 50 tonne small-particle coal delivery which is believed to have a higher than acceptable sulphur content. Having never prepared representative samples for such a large quantity of material, the technician consulted their supervisor and developed an appropriate sampling plan. The technician arranged for the operator of a small front-end loader to take buckets of coal from five equally spaced points around the pile. The resulting material was then combined and mixed in one heap. The technician coned and quartered the heap enough times to obtain a representative sample of about 5kg. He/she arranged for the unwanted material to be returned to the stockpile. On return to the laboratory, the technician crushed the sample and repeatedly coned and quartered the material to obtain an analytical portion.

Environmental 

A field technician trained in sampling natural water systems is asked to sample a bright yellow industrial wastewater discharge into a small creek. The relevant sampling plan specifies that the samples should be collected where the waste water is well mixed near the centre of the creek and at the mid-depth point. The technician also notes that the samples must be collected where turbulence is at a maximum so that the settling of solids is minimal. On arrival at the site, the technician locates where the wastewater is entering the creek. He/she moves downstream to where the waste water and creek water is well mixed and there is little apparent loss of the yellow suspended solids. The technician dons the required personal protective equipment and uses a convenient bridge to collect a set of six samples and duplicates over a half-hour period using the equipment and procedures specified in the sampling plan. Using a field notebook, the technician records all information specified in the laboratory's chain of custody requirements and safety plan for handling potentially hazardous industrial waste.
