Listed PSV manifold in NFPA 58 for LPG storage?

Question asked by on Jun 14, 2019

I was wondering what the intent of a listed manifold for PSVs is in NFPA 58, section On our LPG bullets we have two independent lines communicating with the vapor space instead of a single manifold. Each line has a CSO valve and a PSV that can handle full relief capacity. Would we still be exempt from the restriction on inlet valves per section and
