Unit Of competency

Modification History

Release 1 - New unit of competency

Application

This unit of competency covers selecting and operating floor surfacing machines designed for wet or dry polishing of concrete floors. It applies to concrete cleaning and polishing operations in on-site commercial and residential environments and involves application of skills and knowledge at a sub-trade worker level.

Licensing, legislative or certification requirements may apply to this unit and relevant state/territory and local government agencies should be consulted to determine any necessary certification or licensing for undertaking flooring work. Access to construction sites requires certification of general induction training specified by the National Code of Practice for Induction for Construction Work  (ASCC 2007).
