Looking for some opinions. (NYS Version)
804.5.1 Minimum critical radiant flux. Interior floor finish in vertical exits, exit passageways and exit access corridors shall not be less than Class I in Groups I-2 and I-3 and not less than Class II in Groups A, B, E, H, I- 4, M, R-1, R-2 and S. In all other areas, the interior floor finish shall comply with the DOC FF-1 "pill test" (CPSC 16 CFR, Part 1630).
Exception: Where a building is equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1, Class II materials are permitted in any area where Class I materials are required and materials complying with DOC FF-1 "pill test" (CPSC 16 CFR, Part 1630) are permitted in any area where Class II materials are required.
I have a 2 story R-2 type V construction. Carpet specs indicate comply with Pill test. code doesn't define vertical exit, only vertical exit enclosure. Would the stairs need to be Class II? How about the living room area including the hallway leading to the stairs?
Other component, the exception sends us to 903.3.1.1 sends us to a NFPA 13 system, they installed a 13R system. Appears to me the exception then wouldn't apply.
My opinion is at least the stairs need to be cause we could have upward flame spread. JMO, don't know if it's correct.
