Plasmachem members,
To spare you the effort - a request for a reprint of the report identified by Glenn below (via onLine form to the St Luke's Medical Center website) resulted in a denial of having it, and there was no finding to a search for Dr. Michael Vance at the website. For those interested in obtaining the report, the journal route seems the best option, or offering an attractive bid to Glenn.
Regards,
Tom

Thanks Mike for your experience and advise.
I have a copy of an article from the Annals of Emergency Medicine, August 1986.
This was prepared by a group of doctors at the Central Arizona Regional Poison Management Center of St. Luke's Medical Center in Phoenix, Az.
As this is an old reference, I will give the address for reprints.
You may wish to have one for your lab and as I have done, provide one to the Plant Clinic and EMS and to the local Hospital. I also keep it filed with the MSDS, so if someone is sent to hospital, this article can accompany them.
The Article is:
Digital Hydrofluoric Acid Burns: Treatment with Intraarterial Calcium Infusion
Address for reprints is:

Subject: Treatment for HF exposure
I've been following this discussion on HF exposure with interest. This isn't the first time it has come up on this list, though this time the thread has longer legs.
I've worked with HF for more than 30 yrs. I've never been exposed. I'm a geochemist. I've used HF to dissolve silicate rocks throughout that time period. In all the labs I've worked in we have always dealt with full strength HF. Considering the volumes we use, we can't afford Optima/Sea Star/Ultrex grades. We distill our own. As such we handle full strength in large quantities. It can be done safely. If you are nervous about handling HF (or any chemical for that matter) then don't handle it! You are more prone to having an accident if you are nervous.
Be confident and be careful.
Working in an academic environment we keep MSDS binders in every room where a chemical is used - even dry erase markers! We have a safety pamphlet on HF in the labs in my department that use HF. Much of what has been discussed in this recent HF discussion can be found in these pamphlets. These pamphlets are not manufacturers MSDS's, instead they are provided by SU's Environmental Health Office.
I've read them. I've read much of what is on the internet. I have the 3rd edition of the CRC Handbook of Laboratory Safety at home. I have the 4th edition in my office. Our Earth Sciences Library has the 5th edition on the shelf.
The thing that amazes me is that between the 3rd and 5th edition of the CRC the treatment of HF exposure has not remained consistent. It hasn't necessarily evolved. Benzalkonium chloride (Trademark names of Zephiran and Hyamine 1622) was the rage in the CRC 3rd edition. I can't find it mentioned in the 4th edition. It is back to some extent in the 5th edition. I mention this only to point out that what we may consider to be authoritative sources can't always be trusted.
Joe Cruse's post just now mentions Dr. Trevino cautioning no more than a
5 minute water flush. The 5th edition of the CRC says nothing less than
25 minutes!
As for seeking advice from a health professional make sure they are experts on treating HF exposures. Johan Schijf's story about the confusion between hydrochloric acid and hydrofluoric acid by EMS as well as Emergency room personnel is very real. There are five major hospitals in the Syracuse area as well as SU's own medical center. We have had faculty and grad students experience exposures to HF - always at full strength but in varying amounts. We have Ca Gluconate everywhere in the labs. We have emergency showers and eye wash stations in our labs and we have used them. When we do get an exposure we send people to only one of the hospitals in the area - Upstate Medical Center. Why? Because they are the only facility in the area with the expertise to treat the exposures. Here is the important point - we know what they are capable of and they know that Earth Sciences at SU uses lots of HF. That foreknowledge is critical to timely and proper treatment. If your lab uses HF talk to the hospitals/medical centers in your area. See if they know how to treat an HF exposure - before you need their service!
Even after all of the reading I've done on HF exposure treatment and countless conversations with our EHO office they is one question that I have that remains unanswered...in the event of skin exposure to HF do you flush with warm water or cold water? Do you want the pores to stay open, or do you want them to close? Might anyone have the definitive answer?
Cheers
Mike
