I agree with both the previous posters. A sink and hand dryer are not recommended in the gowning room. 1. It’s a choke point for work flow, and I agree with Roger that operators will skip that step to save time. 2. You don’t want to introduce water in the gowning room. Even if you use ultra-clean water, it can still create humidity and potential contamination, so don’t risk it. 3. Hand dryers create air turbulence, which you don’t want in your clean area. In summary, all gross contamination control should be done outside of the gowning area.
Wipes can be used in the garment room, as well as donning gloves. You can use launder-able gloves for this purpose (as Roger mentioned) or use a low-cost disposable PVC glove.

Hi Jeff,
I’ve called on some experts and believe I have an answer for you.
First, the water for washing should be addressed. The temperature of the water is critical: it should be hot, 18 meghom water filtered to .5 micron. Do not use any surfactant-based cleaners during this process.
As for the air filtration in the area, the percentage of filtration in the ceiling / air exchanges per hour will depend more on the activity within the cleanroom than the class of the cleanroom. In other words, a cleanroom that does not generate much contamination there is not a need for as much air exchange. Any engineer with controlled environment HVAC experience can make a more specific recommendation.
Hope this helps!
