Anyone who is stupid enough to use oxalic acid without
eye protection, even after being warned not to, perhaps
needs to find out why he was warned.

We could argue this until the end of time, but like I tried to say back up
the thread somewhere, I don't use protective gear with OA, but I'm not
saying nobody should. If you prefer to play it safe, by all means do so. I
have no intention of arguing against safety.

Here is a statement from a source for buying Oxalic acid:

Here's the MSDS for the product I use:

About halfway down it lists the health risks. Short contact with skin
appears to be safe, but prolonged exposure can give you anything from
irritation to burns. Eye contact will give you severe irritation and "may
cause transient injury to the cornea," whatever that means.

Anybody using OA should take appropriate precautions to avoid those last
couple things because even a mild or transient injury is still not something
you ought to shoot for. What's appropriate in the precaution department is
really what we're all disagreeing about and I kind of see it as being up to
the individual to decide what constitutes an acceptable level of safety. My
idea of taking appropriate precautions is to avoid squirting the stuff on
myself. Yours may be to add the extra insurance of goggles and gloves.
Somebody more cautious might prefer to avoid using OA altogether. Maybe I'm
too complacent, but I see similar warnings on lighter fluid and super glue
and I don't use goggles or gloves with those, either. Maybe I'll be sorry
some day. If you don't want to be like me, by all means do what you think is
best.
