Corrugated Stainless Steel Tubing (CSST)
Corrugated Stainless Steel Tubing (CSST) is a flexible, stainless steel pipe used to supply natural gas in residential, commercial and industrial structures. CSST is often coated with a yellow or black exterior plastic coating. CSST is usually found on top of ceiling joists in attic spaces, inside interior wall cavities or near floor joists in a basement.
If lightning strikes a structure containing CSST, there is a risk the lightning can travel into and through the structure's natural gas piping system and cause a leak, or in some cases, a fire.
The product is installed in 7 million homes in the United States. It is safe to use when properly grounded. A proper bonding or grounding device will reduce the chances of a natural gas leak or fire.
If you find CSST in your home or business, customers should hire a licensed electrician to inspect the equipment to ensure it is properly grounded.
