Evidence Required

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 projectbased 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

obtain and apply work instructions for the safe and correct removal of friable asbestos

set up the work area and test equipment for use in the removal process of friable asbestos

isolate the site prior to removal complying with regulatory requirements

remove friable asbestos safely complying with regulatory requirements

contain the asbestos containing material and ensure its handling and disposal are safe and comply with requirements

decontaminate self work equipment and work site safely and correctly

complete documentation that supports the removal process within limits of own responsibility

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 offsite 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 industryrelated 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 persons 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

using drums or bins in good condition with well-fitting lids labelled with appropriate warning signs or labels

mini enclosures, such as glove bag and wrap and cut methods (suitable for friable ACM removal from small areas).

Notes:

For larger-scale disposal, the supplier of a waste removal bin must be informed of the usage to ensure appropriate and legal disposal.

If too large for a bin or bag, a skip or vehicle tray may be used provided it is double-lined with heavy-duty thick plastic sheeting. When ACMs are loaded on a truck tray the ACMs must be wetted down and then fully wrapped and sealed with a layer of 200 μm sheeting or bagged. Labelling must occur.
