Most here are strongly in favor of the safe handling and use of chemistry. And not in favor of seemingly hysterical attitudes against the rational use of chemistry. That hurts us all. An undergradute (or even good high school) course in Chemistry 101 should be more than sufficient to teach the lab skills necessary to handle photographic darkroom level chemicals safely, even if one is only a "cookbook" DIY user.
And if you're not DIY compounding formulas on your own and simply using commercially available prepackged kits, just follow the manufacturer's instructions and use common sense.
