In response to concerns, Omega Flex stopped offering its earlier CSST product this fall and instead is promoting tubing wrapped in a special covering intended to make it more resistant to lightning strike damage. Some manufacturers and builders say there may be other contributing factors in the tubing fires, including whether gas lines are correctly grounded and bonded, meaning they're linked into a system that would direct energy from a lightning strike into the earth. The president of the Ohio Home Builders Association said he has used the tubing and has no doubt that it's a safe product when installed properly. "We have it in our home," said Bill Owens, who's also founder and president of Owens Construction in suburban Columbus. "A lot of it is just paying attention to the actual installation requirements and the code requirements associated with safe installation." In Indiana, officials increased code requirements for bonding and grounding in new homes and expanded the required gap between gas tubing and other metal items to help decrease the risk of a problem. The research foundation affiliated with the National Fire Protection Association, which sets national codes that pertain to construction, is studying how to mitigate any lightning-related dangers of CSST and has sought information from various stakeholders in the discussion, including manufacturers and insurers. "Now that it's out there, how do we make it safe?" said Mitchell Guthrie, an engineering consultant from Blanch, N.C., who has researched CSST and lightning protection and worked with a panel studying concerns. Iowa Fire Marshal Ray Reynolds said people in the insurance industry have linked the tubing to more than 200 fires in his state over the past two years, and he doesn't believe proper grounding and bonding is the only solution. He said Iowa has seen some problems with properly bonded systems, and he decided to replace the tubing in his own home with the updated, extra-protected CSST. Wagner, the Ohio homeowner displaced by a fire, said he decided to replace his flexible tubing with rigid lines to help his family feel safer. The American Gas Association, which represents gas providers, doesn't think CSST is a defective product, but it has helped develop product standards and has supported the industry's effort to educate the public about concerns and to minimize any dangers. "It's just a situation that could occur, just like lightning could penetrate a home and damage wiring," said Jim Ranfone, the AGA's managing director of codes and standards. "It's not a panic situation, but it's one that I would sort of keep tabs on to make sure the system was properly bonded," he said.
