I think they were exagerating on the strength of the stuff used to etch 
PCBs, if it were really as bad as they made out then I would expect to 
see much more protective equipment used when handling it.

I took a look to see just how hazardous ferric chrloride (the most 
common etchant among hobbyists afaict) is. Here are a couple of links I 
found.

They give the impression that it's not the sort of stuff you want to get 
on your hands if you can help it but it's not horriblly dangerous 
either. It is VERY corrosive towards most metals though ;)
