For maintaining the health and safety and adhering to the high standards of a controlled cleanroom environment requires thorough training and routine testing and inspections because there are many potential hazards in clean rooms. Several common cleanroom validation hazards are listed below:
- Pass Through Areas –if onehas to bring a lot of equipment and parts into the cleanroom, products and supplies can go through the pass through in the form of a wall mounted or floor mounted cart pass through.
- Double Doors – when designing and building a cleanroom, a double doorhas to installed to bring things in and out, even during the building process to bring equipment in and out of the area.
- Electrical Outlets –electrical outlets are properly sealed. Sometimes, small insects can crawl through outlets as well as airborne duct and contaminates.
- Flooring – If the floor is vinyl it is not an ESD floor. All equipment must be able to be properly grounded to the floor when you’re using ESD chairs, carts, chairs etc.
- Rubber Coving to Walls and Floors – where different finishes have been bonded together, i.e. walls and floors, ensure that the rubber bonding strip has not begun to de-bond from the finishing’s, this can lead to air leakage paths and also allow dust and other contaminates into the clean room environment.
- Communication Devices – if you need your mobile phone and/or walkie-talkies in the cleanroom for communication purposes, it should not be clipped on the outside of your coveralls. They may fall off and damage microchips etc. in all instances if you do need communication devices you can wear small cleanroom waist bagor it can be kept wall mounted. which reduce the risk of damage to your surrounding area.
- Electrical Trunking – ensure all electrical trunking is completely sealed where it terminates through the room/building envelope.
- Holes in the HEPA Filters – Sometimes employees accidently damage HEPA filters by lifting mop handles to high and hitting the underside of the HEPA filters.
- Mechanical Pipe Runs – check that your pipes etc. are properly sealed where they terminate through the room/building envelope.
All these above clean room validation hazards can be avoided under proper training and guidance. Parsan Engineers and Consultants provide a professional cleanroom validation service to the requirements of all current ISO standards and guidelines. Parsan Engineers and Consultants will issue test certificates containing up-to-date calibration certificates for all of the equipment and measuring instruments used as well as recommendations for improvements that could be made to make the clean room more efficient in regards to its operation.
