Just for discussion, look at 8.12.5.1.1. Isn't that essentially a cross section of a baffle? While not specifically having a section dedicated to baffles for ESFR as other sprinklers types do, and allowing spacing's less than 8'-0, what would you do if you had a solid structural beam? Section 8.12.5.1.2 says that you can ignore the beam if you have a sprinkler on each side of the beam. I am willing to bet there is a chance those (2) sprinklers end up closer than 8'-0 in a lot of cases. How is this any different than a baffle, it serves the same purpose? Section 8.12.5.1.2 also does not apply and conditions or restrictions when placing a sprinkler on each side. Am I missing something?

No being a SA (well too much of one) but that is simply one of the annoying limits on ESFR. If close to 8 ft, try a staggered pattern (like often seen in days gone by).
