      before you ask: no, neither the fan nor the channel are spec'd for pumping chlorine but i treat them as a disposables running at a very low duty cycle so it's fine

      Ever messed with HF? I'd like to but that stuff is scary.

      I didn't, never had a very good reason to (delayering ICs is interesting but I'd like to build a reactive ion etcher for that, it's more useful IMO) I would work with dilute HF given appropriate PPE and emergency preparedness, it's not *that* bad.

      Mostly, you have to understand the mechanisms of its toxicity very well, and then it stops being frightening...

      Hypocalcemia, right? Part of the puzzle is knowing where to start researching required PPE and other safety requirements (e.g. should I stock calcium gluconate?)

      look for university safety training guides, e.g. https://web.utk.edu/~ehss/training/has.pdf …

      Thanks! I have a goal to build a small chem lab at Hackerfarm next year, because having a SEM is rather boring when you don't have anything interesting to stick in it. But my experience with chem is basically... chem 101 and 102 back in college.

      I would be very uncomfortable leaving HF around in a hackerspace, eventually someone will underappreciate just how insidiously corrosive it is. Maybe in a safe that only you have keys to. Maybe.

      It's not a very trafficked hackerspace (something about being in the middle of nowhere, eh) but yes, the place doesn't even lock the front door but we'd definitely want this stuff in a locked cabinet.
