Clean Space vs Clean RoomPosted on 09-11-2007
A Clean "SPACE" vs. A Clean "ROOM"
A lot can be accomplished, at very little expense, by having your manufacturing personnel incorporate a Cleanroom Manufacturing Attitude © Involve cleanroom disciplines & protocol along with establishing good housekeeping and preventative maintenance procedures.
Install pressure differential gages to assure that the space you are reworking is positive to other area of less concern. Use a 0.025 pressure differential gage and follow the manufacturers recommendations on “zeroing” the gage after installation. Re-balance the HVAC that is supplying this area if necessary.
If you have only ceiling returns for the airflow, you may not be getting a good removal of the contaminates at the work level. Do a airflow visualization study to determine the differences and effects of both the ceiling and low air returns.
Clean your facility from top to bottom by first using a HEPA filtered vacuum cleaner. Then wipe down the area with a non shedding cleanroom wipe using cleaning solvents that are compatible with your process.
Train your personnel in proper cleanroom protocol and disciplines with items needing to be restricted due to their contamination generating properties.
Establish and maintain a good housekeeping program that not only incorporates the work areas, but also the ceiling, walls and floors. Create a check list so that nothing is overlooked.
Establish and maintain a good preventative maintenance program for all of the equipment in the room along with the HVAC equipment supporting your clean space. Create a check list so that nothing is overlooked.
Establish and maintain an on-going monitoring program for both viable / non-viable’s and ESD. This will be your indicator of how well your area is doing and alert you to any negatives that may be popping up. Create a check list so that nothing is overlooked.
