I would encourage not embracing the defining examples that residential is life safety and storage is property protection and everything else is mushy in-between ground. It’s the system type that dictates the objective. All NFPA 13 systems for all sprinkler types and for all occupancies and uses are considered both life safety and property protection.
As for the confusion over 5.1.1 and 5.1.2, that text has been in the standard since Napoleon was a corporal. That means if one wanted an exact explanation of what was meant, the folks that crafted this sentence are gone and the current batch could / might / probably (pick one) will have something different assigned to those words. My interpretation has always been that the phrase occupancy hazard is a sprinkler term and does not address or influence the building design as dictated by the building code and their associated use of terms. The text in the annex has nothing to do with the issue of comparing what these 2 sections are trying to say. Notice the asterisk is on the title 5.1. so it’s discussing the assignment of an occupancy classification. It rightly points out that an office is generally a light hazard occupancy but there can and will be areas that exceed the fuel load for LH. As such, that area would be a higher occupancy hazard classification. As Galen commented, it is unfortunate that the term occupancy was included. Calling it simply X hazard classification would have worked just fine but changing it now would take an act of congress. Ummm they may actually be willing to look at this since they aren’t doing anything else of significance. As a member of NFPA 13, I probably should add the TC caveat that this is not to be considered a formal interpretation of NFPA or any of its technical committees but just my humble opinion. Well opinion anyways.
