Hello David Vandenberg or Debbie Decker,

I am chair of NFPA 45 Technical Committee, Standard for Fire Protection for
Chemistry Laboratories.  Your email below was forwarded to me concerning a
HF lecture bottle explsion. This is a subject we have discussed at our
committee meetings and that we think NFPA 45 should address so we are
seeking additional information.

One of our committee members (Bill Barlen, our expert on compressed gases)
asked to see the photographs.  I copied Bill and Amy, our NFPA staff
liaison, on this email.

Would you please forward the photographs to us or if they are posted on
some website, could you direct us to it?  Also any additional information
you can furnish about the explosion would be helpful!

Thank you so much for your help,

Brenda L Bronson, P.E.

 We have had this discussion at the meetings and I believe we address it in
NFPA 45.  If not I know I brought it up at the end of the cycle and we

Their are pictures of the lab mentioned.  If they are around I'd like to
see them.

Hi gang:

 From our intranet for your information.  If you want copies of the photos,
lemme know.

BTW, I did have a potentially scary situation with HBr in lecture bottles -
quite ancient stuff.  It has a similar nasty habit of over-pressurizing
over time.  It was managed without incident, several $10K later.

Ya'll be safe,
