Separation Distances - Guidance for NFPA Codes and Standards

Blog Post created by Guy Colonna Employee on Jun 21, 2015

The Fire Protection Research Foundation recently completed a project to determine a basis that might be used by technical committees when establishing separation distances within NFPA codes and standards. Many NFPA codes and standards, in particular NFPA 400, Hazardous Materials Code, specify separation/clearance distances for hazardous chemical storage and processes from other equipment and occupied buildings. Many of these requirements have historical undocumented origins. Guidance, which may inform a sound technical basis for adjusting these distances, was requested by NFPA Technical Committees. The project reviewed a number of methodologies in the literature, both risk and hazard based, that are currently used in the chemical process safety field and may be relevant to the calculation of these distances.  The purpose of this project was to provide guidance to NFPA technical committees on methodologies to develop technically based separation/clearance distances for hazardous chemical storage/processes and their application to the chemical storage and processes. The specific focus of the project is those hazards within the scope of NFPA 400.  The project, which was completed at the end of 2014, included full-scale testing.  A presentation on the report is scheduled for Wednesday, June 24 (W19), from 11:00 - 12:00 in Room 404d. The completed report is available on the Foundation's web page and through the link provided here. A presentation on the report is scheduled for Wednesday, June 24, from 11:00 - 12:00 in Room 404d. http://www.nfpa.org/research/fire-protection-research-foundation/reports-and-proceedings/hazardous-materials/other-hazards/separation-distances-in-nfpa-codes-and-standards
