Steve, if you look in the Handbook commentary, it says that bin box can only be protected by CMDA sprinklers, not CMSA or ESFR. However, 23.1.1(3), 2019 edition, states that ESFR can protect storage arrangements up to EH2 design criteria. It seems like if the bin box storage would require a max of EH2, that it might fall under that exception. Storage height would be a determining criteria. Just my thought not knowing all the facts (again).
