Unit Descriptor

This unit of competency specifies the outcomes required for assessors to visually inspect and use a range of measuring devices to undertake the monitoring of airborne asbestos fibres in the workplace as an integral part of identifying hazards, assessing risks, monitoring the effectiveness of controls, and ensuring that the workplace is free of asbestos fibres prior to reoccupation.

The unit includes the planning of the monitoring process, the selection and use of processes and air-monitoring equipment, the conduct of the assessment process, and the proper handling and interpretation of results.

Asbestos assessment and air monitoring are required during all friable (Class A) asbestos removal and for non-friable asbestos removal where a risk assessment indicates that airborne asbestos fibres may result from the removal activity.

Application of the Unit

Site location for work may be either domestic or commercial, and may be a demolition site, a new work site or an existing structure being renovated, extended, restored or maintained. Project sites may be construction sites and may also include ships, soils and fences.

Licensing/Regulatory Information

Occupational licenses are required nationally.

Work must be completed according to relevant legislative, code of practice, industry, customer and organisational requirements, including work health and safety (WHS) policies and procedures. Testing must conform to National Association of Testing Authorities (NATA) or other accredited laboratory requirements and standards.

Regulatory mechanisms apply to this unit. Candidates are advised to check for regulatory requirements.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

This unit of competency could be assessed in the workplace or a close simulation of the workplace environment, providing that simulated or project-based assessment techniques fully replicate workplace conditions, materials, activities, responsibilities and procedures.

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

A person should demonstrate the ability to:

  • plan for the asbestos removal assessment process by ensuring access to required documentation and consultation with the client and workplace
  • interpret and apply the requirements of relevant legislation, regulations, codes of practice and standards to ensure the safe and correct assessment of the removal of ACM
  • demonstrate understanding of the scientific and technical principles that underpin the ACM removal assessment process
  • undertake preparations for collecting samples, including identification of sampling areas, the sampling process, sampling schedule, air-monitoring plan and strategy
  • collect samples from site and handle in a manner that ensures the integrity of the sample, including use of protocols for the chain of custody
  • prepare samples for analysis and transporting to a NATA or other accredited laboratory
  • interpret and analyse laboratory results
  • conduct site inspections, prepare advice to clients and provide clearance certification.

Context of and specific resources for assessment

This unit is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.

Assessment of essential underpinning knowledge will usually be conducted in an off-site context.

Assessment is to comply with relevant regulatory or Australian standards’ requirements.

Resource implications for assessment include:

  • an induction procedure and requirement
  • realistic tasks or simulated tasks covering the mandatory task requirements
  • relevant specifications and work instructions
  • tools and equipment appropriate to applying safe work practices
  • support materials appropriate to activity
  • workplace instructions relating to safe work practices and addressing hazards and emergencies
  • research resources, including industry-related systems information
  • safety data sheets.

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Method of assessment

Assessment methods must:

  • satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package
  • include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
  • reinforce the integration of employability skills with workplace tasks and job roles
  • confirm that competency is verified and able to be transferred to other circumstances and environments.

Validity and sufficiency of evidence requires that:

  • competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
  • where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person’s demonstrated ability and applied knowledge
  • all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.

Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.

Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
