LIGHTNING STRIKES: 
The following is from a 2007 article : 
               May 2007 -- A Class Action Lawsuit against four manufacturers of a relatively new type of fuel gas tubing has identified the installation of a lightning protection system as a remedy for
the fire  risk associated with CSST (corrugated stainless steel tubing) gas  piping systems. CSST
is a type of flexible piping that has been widely used in homes and commercial applications in recent years. Unlike traditional, heavy-walled gas pipes, CSST is extremely thin and therefore susceptible to damage from lightning. Lightning traveling on the CSST can burn holes in the tubing and allow gas leakage and fire. In worse case scenarios, such leaks have led to catastrophic gas explosions. The CSST has been found to be susceptible to damage from direct and even nearby lightning strikes.
CSST has been widely used in recent years because it is easy to install. According to the National Fire Protection Association (NFPA) however, no tests on the effects of lightning on CSST were conducted prior to its approval for use. One CSST manufacturer has acknowledged that the installation of a lightning protection system addresses the lightning hazard associated with CSST, yet homes with CSST are rarely equipped with lightning protection systems. Lightning strikes the United States more than 25 million times each year. A single bolt of lightning can carry over 100 million volts of electricity, making the hazard to homes outfitted with CSST a serious concern.
