thread_title:  Confusion over particles per cubic meter and particles per cubic foot 

message: Our article on biosafety levels has a list of BSL-4 facilities (those with the most stringent specifications). This article would benefit from a list of the most highly specified cleanrooms. A quick google turns up something about an ISO class 1 cleanroom being built, so can anyone incorporate a list of facilities built to the highest standards?

thread_title: Notable facilities

message: This sentence:
"To give perspective, the ambient air outside in a typical urban environment might contain as many as 35,000,000 particles per cubic meter, 0.5 μm and larger in diameter, corresponding to an ISO 9 cleanroom."
...makes absolutely no sense to me. I have no idea what an ISO is. There are plenty of ISOs but none are referred to or specified in the first paragraph. I have no idea what 9 means i.e. "ISO 9" except that it must be as dirty as the air outside in a city. That doesn't sound "clean" to me. So why is it mentioned as a cleanroom score? What is the scale we are working with? Is "1" clean and 10 dirty? Or is 1 particle-free and 100 = a clod of tightly packed dirt"? Is the "typical city" Paris or Omaha or Bejing?
This first paragraph has the bizarre distinction of being both totally unclear to the cleanroom novice and also horribly written if penned by someone with enough of an education to be an "expert". 70.143.75.66 (talk) 07:00, 12 March 2009 (UTC)

message: Can one have health issues in a clean room??   Room is controlled by temp and humidity.  Everything is stainless steel....vacuumm coating of medical devices.  Using silane chemistry and parylene chemistry...lots of al cohol.  High static electricity in the room.   Use nitrogen to clean medical devices.   Any danger to ones health?   Have red eyes...skin problems, brittle hair, etc. since working in this environment.  We wear hair nets, Tyvek suits, laytex gloves, foot covers and beard guards.  — Preceding unsigned comment added by 50.90.148.176 (talk) 03:09, 3 March 2012 (UTC)
thread_title:  Health Issues from Working in a Clean Room Environment 

message: I have uploaded two photos of the photolithography cleanroom at the London Centre for Nanotechnology onto Wikimedia Commons.
I would propose that one of these could perhaps replace the (low res) photolithography cleanroom pic currently at the top of this article. 
However I leave the decision to another editor - I work for the LCN's parent organisation and want to avoid any suggestion of conflict of interest.

message: : ==Environmental benefits of cleanrooms==
: Cleanrooms offer many environmental benefits that traditional construction often eschews. Modular Cleanrooms provide a re-usable space that saves money on energy, is recyclable and minimizes waste by reducing on-site construction. 
I removed the above because it was uncited and made no sense to me. In fact, because of the energy-intensive air handling required for a clean room, I wouldn't expect it to have environmental benefits. If somebody can make it clearer what it's talking about, or find a reference for it, feel free to add it back. 45.37.166.153 (talk) 19:23, 1 April 2016 (UTC)

message: There are certain applications of cleanrooms which I know, but don't have references to. Some of them quite titillating. And since there Can Be More Than One, maybe they'd warrant their own section, or at least see-also -links. Some examples of which I'm privy to are:
* The so called Bubble Children. Severely immunocompromised medical patients, most tragically those who inherited the compromise from birth, have to be kept in (sterile) cleanroom conditions throughout their life in order for them to survive.
* Deep-core archeology. When we bore into deep ice sheets, in order to understand earlier conditions on the Earth, both the boring process and the subsequent preservation of the bore itself have to be done in sterile conditions, in order to avoid contamination by modern day biome.
* Planetary exploration with regard to exobiological concerns. Each and every probe we send out into the solar system has to be thoroughly sterilized and handled in a cleanroom, not just to avoid contaminating any sample return mission with our lifeforms, but also to avoid contaminating any of the bodies we've contacted. This has been procedure since the first missions to the Moon, and I believe is international law by now.
* Nuclear powerplants. The whole of them are structured as (low-grade, but very real and well-engineered) cleanrooms. The buildings, the procedures, everything is structured around not spreading around radioactive particulates -- complete with inverse pressure through HEPA filters, checkpoints where you have to change your shoes, totally paranoid measurement of radiation levels *and* other particulates (which might become neutron activated and/or carry activation products further by contact), and so on. That one "chimney" you often see sticking out of their roof? It's the centralized exhaust vent from the plant/cleanroom's air filtering system, which is raised into the air; so that in case *everything* else fails, at least the radioactive exhaust gets spread a little thinner, and flies farther away, so that it can decay before it rains down.
* Also, anything having to do with a neutron flux. Because neutron activation products are nasty. In nuclear technology, the best way to avoid activation products, is to make pretty darn sure you don't have anything to activate, to begin with. Hence, again, clean rooms.
* In medicine, isolation wards are effectively clean rooms. Even if their primary function, as in the case of nuclear powerplants, is to stop something from escaping from the room, again, it's also to stop something from gaining ingress as well. Thus, the technology is much the same. * And by the way, every time someone goes into a controlled atmosphere room and goes out of it, you have two acts in two different directions. This is seen especially starkly in the highest varieties of biolabs, studying the most harmful and contagious of organisms, the level-4 labs. Those who handle Ebola, Smallpox, and whatnot. There the technology is as much about not letting something out, as about not letting something in. Maybe this would even warrant its own chapter in the article...might write it myself.
