Generally fine.

Guidance: Hello, this is generally not possible, it is best to pay attention to local disinfection to prevent infection.
Isn't the water in the toilet the same as the tap water used to wash your hands?
The wound is not deep, it is fine if there is not much bleeding, just open the wound and don't use a band-aid. If the wound is deep and bleeding a lot, it is recommended to go for an injection. . .
Pick it out and throw it away, or else block the drain.
It doesn't matter if it's dirty, our skin can cope with this level of pollution, as long as we wash it afterwards and don't get sick from the mouth.
Well, do unto others as you would have them do unto you.
