I bring this issue like others to the forum for a place to throw out ideas hoping for feedback
I believe it is important in a forum environment to share ideas with others who have experienced similar situations My earlier comments were provided so forum members know what my brain is thinking My interpretation is based on reading the code and comments from NFPA specific as I could get to the issue. No, I did not complete fire tests or call my local PE for an answer before starting this thread. I did not know this forum required such high a threshold Feel free to question my authority to ask the forum for insight if that makes you feel better. I know that bravado provides absolutely no value to the forum Sincerely, Exceeding my authority but thankful for the forum ------Original Message------ From: Jeff Hewitt To: [email protected] ReplyTo: [email protected] Sent: Aug 5, 2008 12:24 PM Subject: Re: Floating Ceilings I have been watching this thread with interest, and finally have to ask (and yes, I am sure this will stir the pot as well).... This particular issue is one which requires more than just mundane interpretation of the NFPA 13 standard. Who should be doing the interpreting??? NICET technicians, or PE"s, or ??? My gut feeling here is that if you choose to support the more liberal interpretation, that this will NOT require both above and below protection, especially without any significant test data to back it up at this point, that this is not the place for a NICET technician to make this decision, or for that matter to try to "sell" it to the local AHJ. Do you really want that liability? Not to mention whether you are exceeding your "authority" under NICET rules for practicing engineering?
