I would recommend this program to anyone who wants to get into the field of home and property inspections. This section clearly requires that the metal gas piping be “electrically continuous and bonded to the grounding electrode system.” A separate test can check for leaks at the gas regulator itself: a 30 psi gauge is installed at the outlet of the first stage regulator. following requirements: In industrial occupancies, gas "ThinkSafety 2011 Summer", West Virginia Propane Gas Association, 107 S.
