Webster Mechanical Engineering (WME) provides forensic investigation of property loss and personal injury incidents caused by natural gas and liquid propane (LP) explosions. Fuel gas explosion investigations are conducted in accordance with NFPA 54/ANSI Z223.1 National Fuel Gas Code, the International Fuel Gas Code, and the ANSI and UL standards relevant to the fuel gas fired equipment examined.

WME conducts on-site examinations and testing of fuel gas piping systems and fuel gas fired equipment to verify the source of the gas leakage and the initial ignition source. The examinations include pressure and flow testing of the gas piping system and gas train to locate the point of gas leakage and to quantify the volume of leakage; inspections of the structural remnants; odorant sampling; documentation of the gas utility service pressure, and reviewing the fuel gas usage prior to and at the time of the explosion. WME conducts laboratory examination and testing of piping and equipment components to determine the conditions that led to the gas
leakage and the ultimate explosion.

Our principal engineer’s pre-professional experience as an apprentice, journeyman, and master plumber included the field fabrication and installation of threaded steel and copper fuel gas piping systems in residential, commercial, and industrial structures. His tenure as an Authorized Inspector included inspection and testing of combustion controls and safety devices of large fuel gas fired equipment. His experience as a forensic engineer includes a large number of fuel gas explosion investigations.
