Elements and Performance Criteria

The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available.

What equipment might be relevant to this standard?
Equipment may include mechanically operated drain clearing machines and attachments and manually operated drain clearing tools and attachments.

What OHS requirements might be relevant to this standard?
OHS procedures must be according to State/ Territory legislation and regulations. This may include work site environment and safety, safe use of tools and equipment, use of protective clothing and equipment, and state and local authorities and regulations concerning joining processes and materials handling requirements.

What work requirements might need to be considered and addressed?
These may include site restrictions and procedures, relevant regulations, authorities and permits, incident/accident procedures, standards and certification requirements, and application of safety procedures.

What do drainage lines include?
Drainage lines include surface and subsurface drains.

What should be considered before deciding how to clear a blockage?
This may include access points, availability of equipment, surrounding structure, type of blockage and possibility of combustion, OHS considerations, and type of material.

What evidence is required to demonstrate competence for this standard as a whole?
Competence in troubleshooting blockages in drainage lines requires evidence that a person can plan and prepare for the work, inspect the site to determine access to lines, locate and clear blockages, test the system and clean up afterwards.
The skills and knowledge required to troubleshoot blockages in drainage lines must be transferable to a different work environment. For example, this could include different types of drains, access difficulties, types of blockages and enterprise procedures.
What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below:

types and operational parameters of drains
components used in drainage systems
isolation processes and procedures
levelling and alignment processes
regulatory requirements, codes of practice and relevant enterprise service standards relating to blockage removal, disconnection and reconnection activities
application of OHS procedures when locating and clearing line blockages, use of personal protective equipment and materials handling.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to:

interpret plans, specifications and service manuals
isolate appliances/fixtures/fittings and related assemblies (where required)
repair or remove blockages
use manual and mechanical drain clearing equipment
level and align site
implement and follow relevant enterprise OHS and environmental policies and procedures.

Are there other competency standards that could be assessed with this one?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.
