I wouldn't do that, there isn't enough space in there for your hand, a lemon seed is really small, and you will probably lose one or more of your fingers.
> Okay, but I have pretty small hands, and I take ninjitsu classes at the Y, I'm pretty sure I can do it.
Do you like the nickname "Lefty"?
You are not right (see the detailed sibling comment to your claim to rightness), and either you didn't understand what the original poster actually wrote or you decided to reply to them but say something that's at best tangentially related to their comment and at worst is a pedantic assault on a strawman.
Hence, peak HN.
... actually, "but I'm right!" with no evidence supplied for the assertion might be peak HN.
It is safe to put your hand in a garbage disposal when the power is off! This comment clearly is talking about the safety of your hand from the dangers of a powered-on garbage disposal. The other comment about dropping a garbage dispoal on your foot? no, that does not apply...
> The overwhelming majority of these injuries involve fishing broken glass out by hand.
That is injuring the hand by sticking it in a powered-off garbage disposal.
The comment which was being replied to talked about the garbage disposal eating the hand. It is possible in any situation to invent other branching scenarios based upon word play off the original intent.
Just look at what started it:
> I'd like to put my hand in the disposal and turn it on
so I can catch the lemon seed that's stuck down there
and pull it out.
I wouldn't do that, there isn't enough space in there for
your hand, a lemon seed is really small, and you will
probably lose one or more of your fingers.
The sibling comment refuted the idea that it's perfectly safe to stick your in a powered-off disposal, which was the made-up idea in response to the original post introducing the disposal metaphor.
About one person per month has a reportable injury due to an unfortunate encounter with a garbage disposal. Most years no one gets their fingers mangled. Also, they don't grind your hand to a bloody stump like you'd imagine from horror novels and movies.
The overwhelming majority of these injuries involve fishing broken glass out by hand. A significant minority of them involve dropping the disposal on oneself while installing or removing one.
So no, they're not "perfectly safe" with the power turned off.
You can figure out the analogy here for yourself.
Doubly so if you are reaching for broken glass somewhere where you can't see, that's basically negligence, but still independent of what else that place could do. I just wonder if it would really be different if it was glass in just a pipe without a garbage disposal.
