Propane and Natural Gas Litigation


Since 1979, attorneys with Conner & Winters have represented the propane and natural gas industries in defense of personal injury and large property damage suits throughout the United States.  Our attorneys have been lead defense counsel in over 250 personal injury lawsuits in 35 different states.  Although the Conner & Winters’ propane and natural gas defense group practices out of the Tulsa, Oklahoma office, nearly all of the litigated cases were defended in states and federal courts outside of Oklahoma.

Conner & Winters attorneys have defended all segments of the propane industry, including multistate propane dealers, smaller regional or independent propane dealers, propane marketers, and equipment manufacturers.  We have acted as national defense counsel for the largest propane tank manufacturer and a large midstream propane marketer and transportation company, as well as counsel for the National Propane Gas Association and the Propane Education & Research Council.  Our attorneys are regularly retained by insurance companies who offer specialty retailer marketer programs in various states.  The firm’s attorneys have also represented natural gas utilities in connection with personal injury and property damage claims.

In addition to our experience with propane related litigation, Conner & Winters attorneys have also provided counsel regarding a wide range of issues involving business operations, from supply agreements, operations of propane terminals, consumer education, employee training and employment matters, and Consumer Product Safety Commission recall programs.

Propane and Natural Gas Litigation

Conner & Winters’ attorneys are well versed regarding the fact patterns, technology, and industry standards/procedures in the large damage exposure cases that propane and natural gas defense work presents.  By litigating throughout the United States and being continuously involved in defense work, Conner & Winters has developed knowledge of and good working relationships with leading experts who have specialized knowledge of propane and natural gas cause and origin investigations, chemistry associated with “odor fade claims,” equipment operation and design, and industry practices and standards.  Conner & Winters attorneys have repeatedly litigated provisions of the Liquefied Petroleum Gas Code (NFPA 58), National Fuel Gas Code (NFPA 54), and Guide for Fire and Explosion Investigation (NFPA 921), as well as DOT regulations concerning Hazmat operation of propane transports.  Many states have adopted as part of their state statutes or regulations various editions of the National Fire Protection Association (NFPA) codes.  Others have adopted their own statutes or gas regulations which either supplement or supplant sections of the NFPA codes.  Our attorneys are familiar with the various versions of the NFPA codes and have dealt with multiple state regulations and variations on those codes.  Our expertise and knowledge of variations in codes and industry standards allows us to provide a more effective defense for our propane clients.  In many cases, part of that defense includes dealing with local or state investigators or regulatory officials, and responding to and contesting citations issued to the propane retailer in the aftermath of a propane-related accident. 

Through our extensive involvement in propane and natural gas litigation, the firm has developed close working relationships with numerous expert witnesses and investigators around the country.  As a result, we can quickly assemble a well equipped team of attorneys, experts and investigators to respond quickly to an accident anywhere in the country.  Attorneys in the propane and natural gas practice group are members of the Propane Gas Defense Association and the Natural Gas Claims and Litigation Association.  Relationships our attorneys have developed with members of those organizations allow us to quickly assemble an experienced defense team whenever and wherever an accident occurs.
