Safety valves re­quired on more US gas lines

China Daily (USA) - - BUSINESS -

Ne­wor re­placed gas ser­vice lines for hun­dreds of thou­sands of apart­ments and small busi­nesses across the US must be equipped with in­ex­pen­sive safety valves start­ing next year, fol­low­ing deadly fires and ex­plo­sions over decades that could have been avoided, the Obama ad­min­is­tra­tion an­nounced on Tues­day. The Na­tional Trans­porta­tion Safety Board and many ad­vo­cates had pressed for years to broaden re­quire­ments for so-called ex­cess flow valves, which can shut off gas au­to­mat­i­cally when a line is rup­tured.
