Other units of competency that could be assessed with this unit 

This unit could be assessed on its own or in combination with other competencies relevant to the job function, for example:

  • PRMWM44B Identify wastes and hazards
  • PRMCMN201A Participate in workplace safety arrangements
  • PRMCMN301A Contribute to workplace safety arrangements
  • BSBCMN215B Participate in environmental work practices
  • BSBCMN313B Maintain environmental procedures.

Resources required to assess this unit 

The following resources should be available:

  • job sheet and schedule
  • plant and equipment for placement and compaction of waste
  • waste for placement and compaction
  • safety barriers and signage
  • communications equipment
  • personal protective equipment
  • OHS requirements
  • housekeeping materials
  • MSDS
  • site safety plan.

Gaining evidence to assess this unit 

For valid and reliable assessment of this unit, the competency should be demonstrated over a period of time and be observed by the assessor (or assessment team working together to conduct the assessment). The competency is to be demonstrated in a range of situations, which may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace.

Evidence of competency is best obtained by observing activities in this field and reviewing the placement and compaction of waste at a landfill site under normal industry operating conditions. If this is not practicable, observations in realistic simulated environments may be substituted.

Consistency in performance 

Assessment requires that the plan meets the objectives of the client and that it complies with industry expectations in the particular client environment. If the environment is narrowly defined or is not representative of industry needs, it may be necessary to refer to portfolio case studies of a variety of waste requirements to assess competency in the placement and compaction of waste at a landfill site.

If the compacting of waste process is not representative of industry needs, it will be necessary to assess within a range of sites and with a variety of waste types.

Oral questioning or written assessment and hypothetical situations (scenarios) may be used to assess underpinning knowledge. (In assessment situations where the candidate is offered a preference between oral questioning and written audit, questions are to be identical.)

Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff.

Note: All practical demonstrations must adhere to the safety and environmental regulations relevant to each state or territory.
