Required knowledge

Required knowledge for this unit is:

AS1940 The storage and handling of flammable combustible liquids

behaviour of sealant materials used in structures

job safety analysis (JSA) and safe work method statements

measurement and calculation techniques relevant to surface areas

safe materials handling techniques and requirements, including hazardous materials relevant to sealant application work

types and performance of sealants used in buildings

types and use of hand tools and equipment relevant to sealant application and installation work

workplace and equipment safety requirements.

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, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.

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

A person who demonstrates competency in this unit must be able to handle and use all the sealant materials and application devices listed in the range statement, providing evidence of the ability to:

comply with OHS regulations and state and territory legislation applicable to workplace operations

comply with organisational policies and procedures, including quality assurance requirements

select and use appropriate processes, tools and equipment to carry out tasks

adopt and carry out correct procedures prior to and during handling and application of materials

demonstrate safe and effective operational use of tools and equipment

demonstrate safe application in the process of cleaning up application area and cleaning equipment

communicate with others to ensure safe and effective operations.

Context of and specific

resources for assessment

This competency 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:

sealants and sealant devices appropriate to application tasks

plant and equipment appropriate to application processes

hand tools appropriate to application processes

work location appropriate to activity processes

MSDS information.

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 a reasonable inference that competency is not only verified under the particular assessment circumstance, but is 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 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.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
