Fume hood images
Hi Lozhw, I am going to revert the image changes from those changed to the TION models because of two reasons: If I am in error here please let me know. Recon rabbit  20:13, 8 May 2024 (UTC)
 * 1) These images are taken from the internet and have copyright, so we can't use them.
 * 2) The images are of a specific brand and could be considered advertising.
 * 3) The biosafety cabinet image is being used to demonstrate that because it recirculates particulate generated inside the hood back to the room through a filter, it can be considered a ductless fume hood.


 * biosafety cabinet should never be refered to as a ductless fume hood. It is misleading and should contain an image of a proper ductless cabinet Lozhw (talk) 21:04, 8 May 2024 (UTC)
 * Very well. I'll try to find a photo. I believe one of our nanofabrication labs uses a recirculating hood but it may be hard to access the cleanroom for a photo.

Do you take issue with the statement in the article: "the manner in which biosafety cabinets are operated when not connected to a duct system is functionally the same as a ductless fume hood, though the applications of biosafety cabinets, combined with the relative difficulty in connecting them to a building exhaust system compared to a fume hood, result in different safety considerations." which is supported by the CDC (which states "[the class I BSC] is similar in air movement to a chemical fume hood, but has a HEPA filter in the exhaust to protect the environment") and the Guidelines for Laboratory Design?
