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.

I use: as part of my discussions in my skin exposure lecture.

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,
