wear gloves or join the yellow fingers league.
OK, this is nitpicking, but… my first time getting nitric acid on
me made a huge impression, so I’m going to share.
Your fingers will not turn yellow (though fingernails will, or brown
On the occasion in question, I noticed a white spot on my hand,
thought “Huh! Maybe I got acid on me.” But it didn’t feel like
anything… Later that evening, the spot (about an inch by a half
inch) was blue. Not blue-ish, honest-to-God blue, the color my TV
screen turns when there’s no reception. This got my attention. But
still didn’t feel like anything.
The next morning, my spot was black. Not black-ish… and I’m
thinking “holy s___, what next?”
OK, well, after that it’s an anti-climax. Over the next few days,
the black skin flaked off, never hurt, the affected skin was not deep
enough to leave a mark or anything, but you know, that really just
can’t be a good idea.
A student where I teach, back when I was a student there, put on
gloves and decided that that meant she could just reach into the acid
to take out her piece. Turned out three of the glove fingers had
holes in them.
She was getting married three days later. Bummer.
