MSMWJ302 Operate a drain cleaning system

Modification History

Release 1 - New unit

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.
