National Association of State Fire Marshals (NASFM) Materials on CSST
The National Association of State Fire Marshals (NASFM) has launched a nationwide safety campaign to bring awareness to homeowners regarding yellow corrugated stainless steel tubing (CSST). The materials include a Technical Bulletin on Direct Bonding of Standard CSST.
All manufacturer's instructions have required direct-bonding and grounding of yellow CSST in new installations since 2006. If lightning strikes on or near a structure, there is risk it can travel through the structure s gas piping system and cause a leak, and in some cases a fire. A bonding connection installed on a gas piping system will reduce the likelihood of electrical arcing to or from other bonded metallic systems in the structure, thus reducing the likelihood of arc induced damage.
We encourage utilities to inform customers to inspect their homes for yellow CSST to make sure they are up to current requirements and if they have any concerns to contact a licensed electrician to arrange for a professional inspection.
