Fume hood vs. Fume cupboard[edit]

Well, here in the States we call 'em "fume hoods", ya see. [email protected]

The UK invented them so we can call them what we like. European Standard uses Fume Cupboard. Globally fume cupboard used more.

I don't Think it really matters who invented them or who uses them more...they save lives and isn't that what really [email protected]

In the UK, "fume cupboard" is definitely more common than "fume hood", is this the case elsewhere.... thinking "redirect" here --PopUpPirate 23:36, August 31, 2005 (UTC)

Energy[edit]

Anybody have an idea how much power their fume cupboard fan draws? Nfette (talk) 06:38, 5 July 2008 (UTC)[reply]

Can somebody summarize the main differences between a fume hood and a biosafety cabinet? Thanks —Preceding unsigned comment added by Shudongs (talk • contribs) 15:01, 8 July 2009 (UTC)[reply]

New Introduction; many further edits needed[edit]

I edited the introduction but this article needs a lot of work. In particular, references to codes and standards (ANSI Z9.5 in the US for example).

The whole discussion relative to health and safety is very primitive.

I don't care what we call them, hoods or cupboards, and also I don't think it matters.

There is no one answer for how much power a hood draws. It depends entirely upon the exhaust system design, where you are located (vis heating/cooling the make-up air) and local power costs. We could include some examples however. —Preceding unsigned comment added by Jonorom (talk • contribs) 19:42, 22 November 2009 (UTC)[reply]

"Construction and location" intro[edit]

The article currently states "Fume hoods (fume cupboards) are generally available in 5 different widths; 1000 mm, 1200 mm, 1500 mm, 1800 mm and 2000 mm. The depth varies between 700 mm and 900 mm, and the height between 1900 mm and 2400 mm." Firstly, shouldn't it use centimeters, not millimeters? And also, I think this needs a citation. —Preceding unsigned comment added by 71.184.69.120 (talk) 23:01, 20 December 2010 (UTC)[reply]

Source added; it uses millimetres, now most common in equipment such as this. Have you perhaps looked at a fitted kitchen catalogue recently? --Old Moonraker (talk) 23:38, 20 December 2010 (UTC)[reply]

Section on saving energy[edit]

The section "Behavioral programs to reduce fume hood energy use" has some nice information about saving energy. It has turned into a list of "me too" programs that is excessive. One or two example programs would be all that is needed for the article. Grantmidnight (talk) 15:27, 19 January 2015 (UTC)[reply]

Improvements[edit]

I have re-organized the material more logically, added Wikilinks, and reworded some awkward circumlocutions. More cleanup work is still needed. Reify-tech (talk) 15:31, 5 April 2016 (UTC)[reply]

If anyone's interested in adding material about manufacturing and installation, then this looks like a decent image for the section. WhatamIdoing (talk) 06:10, 3 December 2017 (UTC)[reply]

Reviewer: JMF (talk · contribs) 16:35, 31 May 2024 (UTC)[reply]

I will be reviewing this article over the next week or so. Feel free to contact me here or at the talk page if you have any queries. Note that I will be creating sections as I go and may subsequently go back and change or delete them. So best not to react until I have completed the first cut.

Copyvio detector[edit]

Low (= good) score. Just one alert: the phrase "is a type of local exhaust ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts." is used elsewhere. So best to reword or quote formally, please.

Citations[edit]

The article is well cited.

Lead[edit]

The lead is of satisfactory length, though it looks to me like it could maybe do more to summarise the content. The paragraph on energy waste is valid but takes a third of the lead but nothing like that share of the body. How about remote handling mechanisms?

  • ranging from the handling of perchloric acid and radionuclides to tall floor-mounted models and models equipped with scrubber systems. is not a natural range. It is either "from relatively low-risk high-school systems to advanced systems in professional laboratories that deal with highly volatile poisonous, corrosive or radioactive substances" or "from about 10 cubic feet (0.28 m3) to to tall floor-mounted models" or "simple exhaust at rooftop to full scrubber management". But are radioactive substances really handled in a fume cupboard? I don't think so.
    That sentence was split to give more space to the information being conveyed. I can certainly add more to reflect the article's final state. Laboratory Fume Hoods: A User's Manual and The Sustainable Laboratory Handbook Layout of Technical Building Trades both provide information on fume cupboards designed for radioactive isotopes; I am aware of several that were used in the past at my alma mater.
  • out of the area = out of the enclosure?
    I mean to state that it draws air out of the room the device is in; tried to better explain this.
  • Per WP:LEADCITE, it not required for statements in the lead to be cited but IMO it is wise to have a hidden note (<!-- note -->) to say that it is a positive choice not an omission.
    I've added a comment.

History[edit]

  • If you are going to say that Edison created the first fume cupboard, it needs a date. Was it really before 1904? More generally, what has been called is WP:WEASEL: who called it that? what qualifications do they have to be taken seriously? And as it doesn't seem to have had a front cover, can it really be called a fume cupboard at all?
  • Fume hoods were originally manufactured from wood, but during the 1970s and 1980s epoxy powder-coated steel became the norm. During the 1990s, wood pulp derivatives treated with phenolic resin (plastic laminates and solid grade laminates) for chemical resistance and flame spread retardance started to become widely accepted. Both assertions need citations.
    Both points have been addressed with a source reassessment and rewrite.

Description[edit]

  • Six sides, surely. The door is part of the enclosure.
    My bad on that. I've changed it, though I don't have a specific source stating how many sides are in a fume hood - you can kind of tell by looking at it. Unless you don't count the duct on top as a side, since it's technically open.
    I think we can assume cuboid though no doubt someone somewhere has a spherical pressure vessel. If you really meant five sides as in four walls and a floor, with a "special ceiling", you need to specify.
  • This method of airflow control is intended to: None of these statements are cited.
    They are cited now.
    • protect the user from inhaling toxic gases (fume hoods, biosafety cabinets, glove boxes). Not just inhalation, but also from skin contact (though maybe that only applies to gloveboxes and biosafety cabinets?)
    • Parenthesised note: "fume hoods" is redundant; biosafety cabinet and glovebox are separate articles, distinguishable from fume cupboards.
    • Same query about the parenthesised notes on the next two sections.
    • IMO, lose all the parenthesised notes.
      Done, except to specify in "protecting the environment".
  • For exceptionally hazardous materials,: give both types of advanced containment systems, not just one.
    What do you mean by this? I did include gas cabinets, if that was missing.
    biosafety cabinet and glovebox
    I only mention glovebox as it can be seen as a direct upgrade in terms of separating the user from the hazard by putting physical barriers between both. Only the Class III biosafety cabinet would be necessarily described as an advanced containment system - I can clarify if need be, but in my experience and in the lab safety literature the term almost always refers to a Class II or IIB, which is often providing similar or less protection than a standard fume cupboard.

Pausing review temporarily[edit]

"I'll be back" --𝕁𝕄𝔽 (talk) 16:35, 31 May 2024 (UTC)[reply]

I just saw this - I did address a couple things in the lead section. (Edit - I've done more than that now. When I first worked on this article it was a huge mess of OR, and my method of rewriting may have missed some of that.) Reconrabbit
I'm not really back yet, hopefully tomorrow. But yes, I sympathise, I had exactly the same problem getting Robert Hooke out from under years of accumulated detritus and getting it sourced properly. --𝕁𝕄𝔽 (talk) 23:12, 31 May 2024 (UTC)[reply]
