I get asked by building owners somewhat frequently - what is the required clearance from a sprinkler?
I understand most typical ordinary storage/miscellaneous storage/office/standard spray sprinklers the clearance is 18-inches.
I also understand ESFR requires 36-inch minimum. I'm trying to understand the big picture and not misspeak.
What about other sprinklers, like CMDA, CMSA? Is there a rule of thumb across the board?
