Maintain a clean room' environment
This unit of competency covers the skills and knowledge required for maintaining a 'clean room' environment. Clean rooms are specialist facilities in that the presence of dust presents a hazard to the safe and efficient operation of electronic and other sensitive equipment. Some clean rooms may be pressurised to reduce the amount of dust entering the room. Clean rooms may be used for specialised computer installations, computer equipment repairs, PABX units, manufacturing electronic components environments, laboratories and some sterile rooms for food manufacturing. Cleaning in a clean room environment is a specialised field of cleaning. This unit is intended as an introduction to this type of cleaning and focuses on the need to exercise caution in selection of cleaning methods to ensure safety of personnel and equipment.The unit requires the ability to assess the extent of the cleaning task through knowledge of the characteristics of a clean room environment and by applying and understanding client requirements and company policies and procedures in order to perform the task. The selection of appropriate equipment, chemicals and methods is essential for performing the task safely and efficiently.
