Description
This unit of competency covers the skills and knowledge required to operate a high pressure water jetting system which may be used to clean, prepare, abrade, cut or demolish concrete, steel or other plant, equipment, vessels or infrastructure. 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.Work will be undertaken on a worksite which may be a client's site or a site belonging to the organisation. AS/NZS 4233.1:2013 High 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.The competent operator as defined by this unit of competency will be able to operate independently. Operators who are not competent to operate independently should be competent to operate under supervision (refer to MSMWJ201 Use high pressure water jetting equipment).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. Work will be undertaken on a worksite which may be a client's site or a site belonging to the organisation.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.
