This article discusses the development of National Fire Protection Association 2 (NFPA), a comprehensive hydrogen safety code. It analyses the contents of this document with particular attention focussed on new requirements for setting hydrogen storage systems. These new requirements use computational fluid dynamic modeling and risk assessment procedures technical analyses and defined risk criteria. The intent is to develop requirements based on procedures that can be replicated based on the information provided in the code document. This code will require documentation of the modeling inputs and risk criteria and analyses in the supporting information.
This article also includes a description of the codes and standards that address hydrogen technologies in general. (C) 2008 American Institute of Chemical Engineers Process Saf Prog 27: 328-335, 2008
