Not all products in a home should be designed to withstand threats from electrical arcing damage; however, thin-walled flexible gas piping (also referred to as CSST), which carries a flammable fuel throughout homes, should take electrical arcing and puncture threats into account.
Flexible gas piping should be designed and listed to standards which account for electrical arcing threats imposed on CSST from lightning and residential electrical system fault.
The links below provide resources for interested code and fire officials with information they may consider when participating in product codes and standards improvement processes:
Contact NASFM for more information or assistance on improving the CSST building code in your area.
