Unit Descriptor

Unit descriptor 

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.

EVIDENCE GUIDE 

The evidence guide identifies the requirements to be demonstrated to confirm competence for this unit. Assessment must confirm sufficient ability to use appropriate skills and knowledge to maintain a range of different types of surfaces, fittings and sensitive equipment in a 'clean room' environment. Assessment of performance should be over a period of time covering all categories within the range statement that are applicable in the working environment.

Critical aspects of competency 

• Accurate identification of the types of surfaces and fittings.
• Compliance with company and legislative requirements.
• Outcomes achieved in relation to customer work order and company requirements.
• Safe and efficient cleaning methods.
• Selection of appropriate cleaning equipment and chemicals.

Gaining evidence to assess this unit 

For valid and reliable assessment of this unit, the competency should be demonstrated over a period of time and be observed by the assessor.

The competency is to be demonstrated in a range of situations that may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace.

Assessment of competency may be made through practical demonstration in the work environment or in a simulated work environment.

Key competency levels 

There are a number of processes that are learnt throughout work and life that are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added.

Information below highlights how these processes are applied in this unit of competency.
