Public Service Commission Releases Corrugated Stainless Steel Safety Report

Maryland’s Public Service Commission recently releases a report on the safety of Corrugated Stainless Steel Tubing (CSST).

The Maryland Public Service Commission (PSC) recently released their Report on Consumer Education and Protections Relating to Corrugated Stainless Steel Tubing, pursuant to the 2022 Session Joint Chairmen’s Report.  The report suggests agencies consider adding to their websites information about the potential safety risks of improperly installed yellow CSST, as well as consumer protections.

If lightning strikes on or near a structure, there is risk that it can travel through the structure’s gas piping system and cause a leak and, in some cases, a fire. Corrugated stainless steel tubing (CSST) is a flexible, stainless steel piping system used to supply natural gas and propane in residential, commercial, and industrial structures. Standard CSST is coated on the exterior with yellow plastic. If yellow CSST is found, it is strongly recommended that a licensed electrician be contacted to ensure the system is properly bonded and grounded.
