The Honeywell documents and training programs are really quite good. We do not discuss commercial products on this listserve.
You might wish to speak with Dr. Jennings at Honeywell or one of the other OEHS staff.

Honeywell also has a list of neutralizers and which ones form poisonous or nonpoisonous neutralized products, as well as info on heat evolution etc.

I'm far from an expert on HF, but cover it in my class (very) briefly. I believe I was first directed to the Honeywell site from DCHAS last year and from what I understand they are one of the experts in the field.

There are more documents at:

Hi all,
I really need the collective wisdom of the group...
I am trying to develop a safety plans for working on a large scale (manufacturing of batches from 10kg to 200kg) with HF, yes I have a very good idea of how dangerous it is ! and fluoride waste treatment.
Any suggestions and ideas would be appreciated.
Thanks in advance,
