Identifying and following clean room/clean work area protocols

This standard defines the competences you need to identify and follow clean room and/or clean work area protocols, in accordance with approved procedures. The clean rooms and clean work areas will include wafer processing or die assembly and test facilities. In particular, you will be expected to follow any prescribed preparatory activities for the clean work area, to use work methods that satisfy organisational and industry protocols, to wear and care for appropriate personal protective clothing and to follow requirements in relation to your own clothing and accessories.

Your responsibilities will require you to comply with organisational policy and procedures relating to working in clean rooms and clean work areas and to report any problems with the protocols that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking full responsibility for your own actions and ensuring that they comply with approved organisational procedures relating to the clean room and clean work areas.

Your underpinning knowledge will provide a good understanding of your work and will provide an informed approach to complying with approved clean room and clean work area procedures. You will understand the organisational protocols for clean room and clean work areas and their application, in adequate depth to provide a sound basis for carrying out the activities to the required specification.

You will understand the health, safety and cleanliness precautions required when working in a clean room or clean work area environment and with the associated equipment. You will be required to demonstrate safe working practices throughout and will understand the responsibility you owe to yourself and others in the workplace.
