Concerning fire flow, you mentioned that the IFC is based on the ISO Method, how close are they and can you provide any more background on that?
If a building meets IFC, would you expect it score very well under an ISO evaluation? Posted anonymously for discussion. Discuss This | Submit a Question | Subscribe

The part of the ISO method that isn't accounted for in the IFC tables is the exposure factor. That deals with exposure to and from adjacent hazards. Without the particulars of the building in question, it is hard to say how closely they will correlate.

I have an article that I published a number of years ago on needed fire flows using the various codes and methods. Contact me and I can e-mail you a copy ([email protected]).

ISO Needed Fire Flows (NFF) are used for evaluation of a community Public Protection Classification (PPC) grading. The formula includes a Construction Factor,Occupancy Factor, and a Exposures and Communications Factor. There are some other adjustment considerations as well. This leads to a NFF greater than the values stated in the IFC or NFPA 1. Leave a Reply. |
