Emergency Lighting for Warehouse Racking Areas?

[arion]

Hi, I am designing a "designated" exit path in a storage rack warehouse so the electrical contractor can determine which lights are required to have emergency power to meet the minimum 1-foot-candle requirement. I have included a 44" wide "designated" perimeter around the racks themselves, and currently have the "designated" paths leading from that loop around the racks to every single exit door in the warehouse immediately adjacent to the rack area (but no defined "designated" paths outside of the scope of work, which are the racks). If the building happens to have 10 exit doors immediately adjacent to the rack area, and let's say (using occupancy calculation of 500 persons for warehouse occupancy) that say only 3-4 exit doors are required to be present, do I have to classify all paths leading to the existing 10 doors as a part of the "designated" path just because the doors happen to exist, or can I provide only paths to the minimum number of doors required (3-4 paths to doors), and distribute those paths equally throughout the "designated" area?

Lastly, is there any deeper detailed information that anyone can suggest on learning how to strategically create "designated" paths better? The NFPA 101 calls for paths to be "approved by the AHJ" but does not really have clear examples or figures from what I see. Any other quality resources?

Thanks!
