Application
This unit of competency specifies the outcomes required to ensure clean-room environments housing electronic and other sensitive equipment are cleaned and maintained to avoid dust and moisture entering equipment and cabling. It covers assessing the extent of the cleaning task and selecting and using the equipment, chemicals and methods required for the task.
The unit supports cleaners who work alone or in teams. It applies in a range of commercial and residential work sites. Clean rooms may be used for specialised computer installations, computer equipment repairs, installation of PABX units, manufacturing electronic components, laboratories and sterile rooms for food manufacturing. Some clean rooms may be pressurised to reduce the amount of dust entering the room.
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.
