Recent events, such as the Carbide Industries explosion in Louisville, Kentucky in March
of 2011, have raised questions regarding the technical basis for the separation
distances between hazardous storage/processes and occupied areas in NFPA standards,
many of which have an historical basis. Guidance which may inform a sound technical
basis for adjusting these distances has been requested by NFPA Technical
Committees and the Foundation has initiated a project to develop this guidance.
