If your home or business was built after 1990 or you've had work done to your natural gas system it's likely that Corrugated Stainless Steel Tubing (CSST) was installed.
If lightning strikes a structure containing CSST, there is a risk it can travel along the structure's natural gas piping system and cause a leak or, in some cases, a fire.
CSST does not connect directly to appliances, but instead it runs through a home or business - sometimes under floors, along sidewalls, and in the attic.
CSST is a flexible, stainless steel pipe and often has a yellow, or sometimes a black plastic coating.
CSST gas piping systems shall be bonded to the electrical service grounding electrode system at the point where the gas service enters the building. The bonding jumper shall not be smaller than 6 AWG copper wire or equivalent.
Terrebonne Parish does not provide inspection service for CSST installations.
If you find CSST after inspecting your home or business, Terrebonne Parish recommends that you contact a licensed electrician to make sure it's bonded and grounded properly.
If you are unsure whether your building contains CSST, contact a building inspector to obtain a professional inspection.
