Untitled[edit]

The first meaning of "cleanroom" for software engineering? I am skeptical.

the article is a double: Clean room

This should be a disambiguation page to the existing clean_room and clean_room_design pages.

There should be a disambiguation page[edit]

Just that: there should be a disambiguation page. Industrial "clean room" has nothing to do with the Software Engineering meaning.

I've split Cleanroom(Software Engineering) to a separate article and added disambiguation links on top of both pages.Skydiver 13:42, 7 December 2005 (UTC)[reply]

Cleanroom class comparison[edit]

The cleanroom class comparison is off by about a factor of 35. Either fix or ditch :-) --Ihope127 21:54, 3 October 2005 (UTC)[reply]

It's now off by only a factor of 3.5. --User:driscolj

Need history[edit]

This page should include the history of clean rooms. Part of it involves Willis Whitfield, whose story is shared at this link: http://www.hsutx.edu/advancement/news/hol/06-whitfield.htm

New Table to do[edit]

British standards (BS 5295) need to be totally corrected using these sources:

Confusion over particles per cubic meter and particles per cubic foot[edit]

This page refers to number of particles per cubic meter and particles per cubic foot. Only one should be correct

Notable facilities[edit]

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? Rovaniemi-5 (talk) 18:33, 27 April 2008 (UTC)[reply]

Huh?[edit]

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)[reply]

ISO 9, I suppose, it's ISO 14644-9 «Classification of Surface Particle Cleanliness». 89.222.152.170 (talk) 17:13, 20 May 2009 (UTC)[reply]

What About Medical Cleanrooms?[edit]

Perhaps the search "Cleanroom" should direct to a disambiguation page, with a link to this article, and the article on medical isolation rooms, as some hospitals call their isolation rooms "cleanrooms"96.230.195.138 (talk) 22:20, 28 February 2010 (UTC)[reply]

Is there an estimate of the number of clean rooms (per standard) in the world? —Preceding unsigned comment added by Fulldecent (talk • contribs) 15:02, 9 March 2010 (UTC)[reply]

Health Issues from Working in a Clean Room Environment[edit]

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)[reply]

GMP EU classification[edit]

The values given in the table for GMP EU classification do not correspond with values in the source article. Can someone double check these with legislation and correct (if necessary)

Possible new photos[edit]

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.

I like the first one and think it's better than the current lead image. Andy Dingley (talk) 10:21, 22 August 2013 (UTC)[reply]

The current one is too grainy, though it does show more of the room. I'd support replacing it with the first image, here. -PC-XT+ 05:06, 23 August 2013 (UTC)[reply]

Removed: Environmental benefits of cleanrooms[edit]

==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)[reply]

Maybe we should add a section on unconventional/unintuitive applications of cleanroom tech?[edit]

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.

William (Bill) C. McElroy Jr. resume[edit]

In the History section, the last paragraph seems to be Bill McElroy Jr. adding his own resume to Wikipedia, as the only reference to the entire paragraph is just his own name and title, without a link to a third party reference or citation. I'm thinking the paragraph needs to be properly sourced or deleted. Gentgeen (talk) 21:21, 9 February 2022 (UTC)[reply]
