I have a question about one of the most mysterious codes of all apparently. NFPA 1 chapter 15. Now it seems pretty straight forward but, why does anyone I ask give me a blank stare and say huh.

During the current national emergency, and the push to create spaces for patients, how does NFPA 99 and NFPA 101 relate to occupancy changes?

NFPA Code of Construction

I am looking for guidance on whether sites are held to current year NFPA codes or the "code of construction" like one would be with B31.1. How would one find the NFPA code during the year of construction if that is the case?

When the material itself without coatings has a flame spread index of 25, it must ignite and burn in the ASTM E 84 test to determine the index.[section 4.7 (1)]. Think of un-coated steel or concrete and its flame spread index. Will it ignite and burn under ASTM E84 testing? Therefore, to me, the only equivalent would be to pass the ASTM E136 test.

Nick I totally agree with you. There may be no national standardization of the ventilation rates for C1D1 rooms. But there are some recommendations from NFPA 497 that an engineer may consider for electrical safety. There is no best design that everyone could use. The ventilation rates can not be prescribed for a consistent national code…
