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. Fire Protection Engineer GSA Rocky Mountain Region PO Box 25546 (8PF) Denver, CO 80225 303-236-8000 X 5227 Fax 303-236-3606 Cell 303.941.7634 "Bill Barlen"

If not I know I brought it up at the end of the cycle and we should. Their are pictures of the lab mentioned. If they are around I'd like to see them.

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.
