Issue Date: May 2024


Qualification -
Unit of Competency MSMWJ302 - Operate a drain cleaning system
Description
Employability Skills
Learning Outcomes and Application This unit of competency covers the skills and knowledge required to operate a drain cleaning system which may be used to clean, unblock or remove debris from a closed drain (pipe) or open channel drainage system. It covers stormwater, wastewater (domestic type sewerage), trade waste/industrial, publically and privately owned drains and related infrastructure. This work is undertaken in compliance with AS/NZS 4233.1:2013 High pressure water jetting systems - Safe operation and maintenance and Section 6.8 Lancing, pipe and drain cleaning, or its authorised replacement, and Safe Work Australia Guide for Managing Risks from High Pressure Water Jetting (December 2013), its state/territory equivalent (where one exists) or the authorised replacement.Work will be undertaken on a worksite which may be a client's site or may be public space.Operators will also need to be competent in a range of other units of competency in order to be allowed to operate independently on site.AS/NZS 4233.1:2013 High pressure water jetting systems - Safe operation and maintenance states that 'Verification of competency or refresher training on high pressure water jetting operations shall be carried out and documented at appropriate intervals not exceeding two years to ensure the continued competency of operators'.No other licensing, legislative or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Competency must be achieved before performing this work unsupervised. Therefore this unit will typically be assessed off the job. Where assessment is undertaken on the job, appropriate supervision and safety precautions must be provided.

The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.

While drain cleaning equipment meeting the requirements of Class B must be used, the plant/job requiring drain cleaning may be a realistic simulation of an industry plant/application/situation.

All appropriate tools, equipment, paper work/permits and safety gear required will be available and used as required. The assessor should only intervene if it would be unsafe to allow the assessment to continue. It is expected that one assessor would not observe a group larger than ten persons at the one assessment event.

Off-the-job assessment must sufficiently reflect realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessment in a simulated environment should use evidence collected from one or more of:

walk-throughs

demonstration of skills

industry-based case studies/scenarios

‘what ifs’.

Knowledge evidence will be collected independently of the above practical assessment and may use workbooks, written assessments, interviews (provided a record is kept) or other methods.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.

Persons seeking verification of competence/retraining to comply with AS/NZS 4233.1:2013 High pressure water jetting systems - Safe operation and maintenance or its authorised replacement must meet the same evidence requirements as above.

The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.

Foundation skills are integral to competent performance of the unit and should not be assessed separately.

As a minimum, assessors must satisfy the Standards for Registered Training Organisations 2015 assessor requirements.
