Default Re: etching, start to finish

Acid is safe enough to work with provided you do all the right things. No different than anything else

Splashes are obvious. The most incidious thing are the fumes.

Wear a proper fume mask and make sure that any fumes are blown away from you at all times, preferabley outside. A small cheap fan works well. Or better still make a fume cabinet with a small extraction fan if your doing a lot of it.

The fumes can reconstitute in your lungs and damage them within seconds. Or, over a prolonged period completley stuff them. The one basic rule with acid is...........if you can smell it......then your breathing it.

That's my cheery thought for the day
