Pennsylvania state officials recently warned homeowners about dangers associated with yellow steel tubing used to supply natural gas to appliances, according to a report by CBS Philadelphia.
The concern has to do with homes constructed or renovated since 1990 that have flexible yellow CSST (corrugated stainless steel tubing) that supplies natural gas or propane to appliances, the article states. "It's been determined that when lightning strikes on or near a building, there is risk of fire from electric arcs that can perforate the tubing, causing the gas to leak and ignite," CBS reported.
Pennsylvania Fire Commissioner Ed Mann said that homeowners need to make sure the tubing is properly grounded. "Direct bonding the yellow CSST reduces the chance for the arc to occur, making the home safer," he said today. "So if you see yellow tubing in your home, you should take steps to insure that it is properly bonded by contacting a licensed electrician."
