Also had to fight to allow switch from their requested PVC to CPVC so we had listed FP material. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Friday, March 05, 2010 7:46 AM To: [email protected] Subject: RE: "SCIF" Wall Penetration I agree, George. I have allowed dielectric unions but some government agencies insist on a section of CPVC inside the SCIF within 6 inches of the wall being penetrated. Thank You Rahe Loftin, P.E.
