Hi Todd, I did not see a response from Chris yet. Can you forward that to me?
Thanks, Cliff -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Todd Williams Sent: Thursday, November 11, 2010 5:33 AM To: [email protected] Subject: Re: Seismic Question Cliff, Chris is on the right track. There is nothing I know of that provides "blast protection" for sprinkler systems. The impact loading of a blast is probably a lot more severe than an earthquake and what we normally use might not do much of anything. The EOR needs to provide you with specifics. I would start with an RFI stating that there is currently no bracing listed for blast protection and to advise on materials and methods.
