Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I was etching a PCB a few minutes ago. I thought I'd beef up the
FeCl3 with a little HCl so I went in the other room, got the bottle
and opened it. On my back to the kitchen sink where I was doing the
etching I tripped, splashed a little of the HCl into my face (luckily
the cap was still partly on) and dropped the bottle. A little of the
acid went into my left eye so I put my head under the tap and flushed
the eye out thoroughly. Of course, I shouldn't have removed the cap
until I was at the sink. I suppose I ought to get the eye checked,
but I can see perfectly out of it, although it's a little sore, so I
won't bother. The effect was like peeling onions, but a ∗lot∗ worse.
Onions generate H2SO4 when the juice gets into the eyes, same sort of
effect.

It's 30% HCl, BTW, quite concentrated.
