DOE has identified consistent safety, codes, and standards as a critical need for the deployment of hydrogen technologies, with key barriers related to the availability and implementation of technical information in the development of regulations, codes, and standards. Advances in codes and standards have been enabled by risk-informed approaches to create and implement revisions to codes, such as National Fire Protection Association (NFPA) 2, NFPA 55, and International Organization for Standardization (ISO) Technical Specification (TS)-19880-1. This project provides the technical basis for these revisions, enabling the assessment of the safety of hydrogen fuel cell systems and infrastructure using QRA and physics-based models of hydrogen behavior. The risk and behavior tools that are developed in this project are motivated by, shared directly with, and used by the committees revising relevant codes and standards, thus forming the scientific basis to ensure that code requirements are consistent, logical, and defensible.

The intent of the Building Fire Consequence Index (BFCI) at Sandia National Laboratories (SNL) is to provide a method to rank buildings based on the consequence of a fire in that building. This indexing tool will be used to determine the frequency a building's fire protection assessment (FPA) will be performed. Per DOE O 420.1C Chg. 1, Facility Safety, a FPA must be conducted annually (for facilities with a replacement value in excess of $100 million, facilities considered a high hazard, or those in which vital programs are involved), every three years (for remaining low and ordinary hazard facilities), or at a frequency with appropriate justification approved by the Depaitinent of Energy (DOE) head of field element. The BFCI provides a method for a graded approach utilizing a scoring criteria for various categories such as replacement plant value, building content value, hazards, mission dependency index, etc. when assigning FPA frequencies1.
