CSST (Corrugated stainless steel tubing) isn't necessarily the biggest fire hazard in your home–but it's the biggest one you've probably never heard of. 

In short, CSST poses a genuine fire hazard if it's not installed and grounded properly.

CSST is thin. Lightning surging through improperly grounded and bonded CSST can arc, puncture a hole in the line, ignite the gas inside and cause a fire.

When it was first put on the market in 1998, there were ambiguous installation regulations and codes in place. As a result, even today 17 percent of the home inspectors, plumbers and electricians surveyed by Angie's List said they don't ground and bond all CSST.
