Hi gavgnr, welcome to the forum.
As you may or may not know, nicotine is a poison, even at a low level concentrate
like in nicotine juice. The skull and crossbones has to be there to warn that a poison
is included inside the bottle.
If you were to pour the e-liquid over your skin, you may get a headache, feel nauseous,
light headed etc, but you're not going to do this, you're going to vape it.
As for your child, you are of course not going to let him near it, play with the bottle etc,
anymore than you would let him near a bottle of bleach. Thats why these bottles have
safety caps on them. Just keep your liquid out of reach, in a high cupboard, or even lock
it away if you feel the need. It's just safety measures that should be followed.
Now, if you get liquid on your skin, wash it off with water, it really is that simple.
I've had e-liquid on my skin and in my mouth before, and it really isn't anything to panic
And just as Chunky said, inhaling cigarette smoke is toxic too
Don't sell your kit, we all panic a little when we first start vaping, but there really isn't anything
to worry about
