Glass Etching Acid Disposal

I have not used HF since I was an apprentice glass painter at Daprato Studios in Chicago about 1962.We had a dedicated cement sink with a standpipe and contiunous running water, a small fan blowing the vapors somewhere! while I held each piece of glass and mopped the acid with a brush and rinsed .I no longer have access to the Chicago sewer system , I have a mound septic system . How do you handle your acid.
Working on a job that requires many etched pieces. Sandblasting is inadequate.

Milly's reply: Yes, hydrofluoric acid is suitably lethal. It's amazing how lax I used to be with health and safety. But not anymore - here's a link to the dangers of HF acid, in case you don't know already: Dangers of Glass Etching Acid.
I only ever etch glass in a dedicated industrial fume cupboard, like the one pictured. It has running water and fume extraction. I wear all sorts of protective clothing, including two pairs of gloves, plastic apron, a mask if using strong acid - I look like I'm working with nuclear waste.
I have an agreement with the company that supplies me with the acid that they take it away and dispose of it safely. Here in the UK the council want to know if you have something this dangerous.
Glass etching acid gives some of the most fantastic results, it's just a shame that it's so dangerous. And sandblasting never gives you the glassiness that you want. I hope that helps - be careful - and I'd love to see your finished commission, and hear more about Daprato Chicago studio if you want to post some more on the site.
