I am a little concerned about all these concerns about the "extreme dangers" of HCl
. I buy this stuff in the hardware store in 5 liter jerry cans, at concentrations of around 30% to 35%. Yes, this stuff fumes heavily. It is used by the liter for cleaning walls, concrete constructions etc. All those people, using HCl are non-chemists and they all are happily working with it.
So, if you play with the 30 ml vial of this, just use common sense and don't inhale too much of the fumes. If you accidently inhale some of the fume, don't worry, and be more careful next time. Avoid contact with skin and eyes. Again, if some comes on your skin, simply rinse it away with water and be more careful next time. Only contact with the eyes is really serious, so avoid that at all cost.
The only real good advice is the use of contact lenses. Yes, that can be a problem with conc. HCl.
I don't know the price of the 30 ml HCl, but you probably overpaid a lot. You can buy it in gallon quantities at 25% to 35% (depending on country) for just $10 or so, and that material is almost colorless and suitable for almost every home chemistry experiment.
