Beam rule: Check 3X rule which only applies to structural members in LH: Check
Last would be Suspended or Flr mounted obstructions of 8.6.5.2.2 but it states "The distance from sprinklers to privacy curtains, freestanding partitions, room dividers, and SIMILAR obstructions". I like the suspended part but not the "& similar obstructions" part as all the examples shown and discussed are varying types of partitions which obstruct sprinkler discharge from reaching the other side. I don't think a suspended duct is similar in that regard. Nevertheless - it looks like 8.6.5.2.2 is it?
