Unit of competency
Modification History
Not applicable.
Application
This unit of competency covers the skills and knowledge required to use high pressure water jetting equipment under the supervision of a competent operator. The job may be to clean, prepare, abrade, cut or demolish concrete, steel or other plant, equipment, vessels or infrastructure.
Work will be undertaken on a worksite which may be a client's site or a site belonging to the organisation.
This work is undertaken in compliance with AS/NZS 4233.1:2013 High pressure water jetting systems - Safe operation and maintenance, 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.
AS/NZS 4233.1:2013High pressure water jetting systems - Safe operation and maintenance defines this work as work with:
(a) High pressure water jetting systems pressurised by positive displacement pumps with an output capability greater than 800 bar litres per minute.
(b) High pressure water jetting operations carried out at pressures above 800 bar litres per minute and includes jetting operations involving the use of additives and abrasives.
(c) Water jetting operations below 800 bar litres per minute where there is a foreseeable risk of injury to operators.
It further defines:
High pressure water jetting systems with an output capability greater than 800 bar litres per minute and less than 5600 bar litres per minute are identified as Class A and systems with an output capability in excess of 5600 bar litres per minute are identified as Class B.
This unit covers an operator who is competent to operate under supervision. For a competent operator who is to operate independently MSMWJ301A Operate a high pressure water jetting system should be used.
AS/NZS 4233.1:2013High 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'.
Competence may also be required in a range of other units of competency in order to be allowed to operate on site under supervision.
No other licensing, legislative or certification requirements apply to this unit at the time of publication.
