The RA 4 processor is a Hope 26" (measuring 36"x57"). It is a commercial style processor, meaning it has fairly large bathes. The darkroom will be held in the basement of a house where the owners have a small child.
In addition to the type of processor and environment, I am a binge printer. I spend 2-4 days, 12 hours a day every week to two weeks making prints. My initial plan was to print twice a month, mixing the chem's prior and dumping and cleaning the processor afterward. It is my hope that this will keep the bleach stink down to a minimum, allow the room to air out and to minimize the chance of algae, bad chemistry and a dirty machine.
My knowledge of ventilation is small. I have been doing a search for Ventilation: A Practical Guide. It seems very well regarded, but impossible to find. During the search I have learned a great deal more about ventilation. Most of the publications I have run across, assume a greater knowledge of HVAC then I presently have. The concentration toward being Practical appears to be what makes this book attractive.
I suspect, I can find the Kodak publication and see if it is applicable and understandable.
It also appears that I have put the cart in front of the horse. Opposed to organizing the room around drainage it should be built around the work flow (Enlarger -> print processor or dev trays - > wash -> dry) and to find a way for the drainage to be accommodating.
Currently I had planned on having the prints dry on screened racks. In addition to advice about ventilation, I am more than a little open to hearing how others dry their prints.
