I know this seems like an odd question but the ventilation in our club's darkroom needs to be specifically reworked if any of our processing chemicals are flammable. I checked the back of the BW Ilford chemistry I have laying around and it doesn't have any such warning. Gut feel tells me it's not an issue but I want to toss out the question here. There will be no unconventional (like Nitrate-based) films processed here. Just BW, C41 and E6 modern emulsions. Thank you!
