Mark, you have just entered my house. First you have to know if they are doing open pan B&W, tank film developing, or using B&W or color processors. Do they do toning? Are they experimenting with any alternative processes? And are they mixing from powdered chemicals or getting in the cubitainers of liquid? And much more. You have to design to what they are actually doing and the chemicals they actually store and use.--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchas
There are several companies that sell off the shelf vented darkroom sinks and most of them don't work worth a damn. I've set up dozens of these photo labs. I can steer you to the one walk-around developing sink with slots at the lip that works and the company that makes them. That sink is really only useful for open pan developing. If they are doing other types of developing, you either have to make one of the companies modify their ventilation designs so they will work or get an industrial engineer to design specifically to the purpose.
I do a whole section on my ventilation training for architects on photo darkrooms because everything that can possibly be done wrong I have a good picture of from some college or other. And once you understand the principles of industrial ventilation, there is nothing that will get a good laugh (or tears, depending on whose responsible) as most of the ventilation systems in most darkrooms.

Subject: [DCHAS-L] Darkroom Design Standards
Hi All,--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchas
Does anyone have a darkroom design standard (or general safety guidelines) that they can share? One of our research groups is moving buildings and we need to setup a new darkroom for them.
