7 Strategies to Better Cleanroom Gowning

It may not come as a surprise that most clean room contaminants begin with employees. Dead skin cells and hair fragments constantly shed from our bodies. And according to one cleanroom expert, viable bacteria emissions from normal activity by an un-gowned individual could release several hundred colony-forming units per minute; therefore, personnel, above all else, should be properly covered before entering the controlled environment. Otherwise, all efforts and costs to maintain your clean room are negated.

With a well-designed gowning area, proper cleanroom garments, and a strict gowning procedure, particle dispersion is minimized and the cleanliness specifications of your contained space remain uncompromised.

以下是维持最佳贵宾常规的七个提示。注意，在贡献过程中，前两个既又复制污染：

1. Gravity affects particles, too

Depending on the layout of your gowning room and whether garments are disposable or reusable, donning and doffing procedures will vary. However, when gowning, always be sure to start from the top and work your way down. The order in which items are donned directly affects cleanliness; a head-to-toe procedure safeguards against particles falling on clean garments or booties.

2.保持清洁

为了避免污染物的转移，请勿触摸任何脏污的清洁表面。大多数违反污垢的行为发生，当脏的手或不合格的地板与衣服接触时会发生。所有水槽和手动烘干机都应配备无触摸传感器，捐赠区域表面应保持超薄，以保持衣服清洁度。

3. Carefully consider specifications

Each cleanroom requires garments that are appropriate for a specific ISO class of cleanliness. Personnel should only wear garments that have been approved for, or are better than, this regulatory level.

4. Cover up!

Any openings must always be covered. Tuck hoods inside of coveralls and wear boots and gloves over pant legs and sleeves. Confirm that all personnel are trained on how to seal gaps between clothing.

5.它看起来如何？

Ensure that cleanroom clothing fit properly; garments that are too large or too small could increase the number of particulates. Check your appearance in a mirror, or work with a partner to spot escaping hair or jewelry that was not removed.

6. Where can I walk?

“Dirty” and “clean” areas should be clearly designated within the changing room to avoid confusion or accidental contamination while dressing. All gowning rooms should consist of three designated sections: the non-sterile, pre-gowning area directly outside of the room, where personal items are kept and shoe cleaning occurs; the sterile “dirty” side, where personnel perform necessary activities to prepare for gowning; and the sterile “clean” side, where final steps are taken just before entering the cleanroom.

7.如果你必须移动，慢慢做！

通过节约运动，减少可能搅拌污染颗粒的湍流空气。洁净室衣服可能是由棚子的织物制成的，所以人们即使坐着，也会发出颗粒。在敷料的最终阶段，必须缓慢移动并减少不必要的运动。正确安排的更换室将使人员在前往每个站的情况下慢慢降低，而不会阻碍整体流量。

Keep these tips in mind when designing your gowning room protocol, specific to your applications. No matter how sterile your controlled space is, careless or inadequate gowning practices could potentially weaken the integrity of your cleanroom. Gowning matters!
