I too would like to make it clear that I in no way think that other people should not be using dichromates in their private photographic work, or that I think it is unsafe to do so.
One thing that has changed in the time since I started working in labs is the definition of 'adequate ventilation'. A fume hood or well-designed darkroom ventilation would make a lot of sense, rather than trusting to luck. Similarly, I would wear safety goggles to guard against accidental splashes or dust entering my eyes.
Sandy: do you use a reducer to convert the chromium VI before disposal? I have seen suggestions to use sodium thiosulphate - do you have any other recommendations?
