Hi - I just stumbled upon your posting (at http://www.classiccmp.org/pipermail/cctech/2002-December/006703.html ) from last year - can you tell me if you had any other occurrences of this, or if you had any other responses beyond those linked to your post? Our fire protection engineers tell me this has been a bit of a problem, but I am not finding much information as I look into it for a class project. Did your local fire department respond to the three you mentioned, and was there an investigation / report? Thanks - Mike Mike Holder Boeing Fire Inspection (206) 544-7950 (206) 416-2020 pager (P.S. - Would you have saved the faulty suppressors by chance? I'd be very interested in seeing one - or more!....
