What should I do about a sprinkler contractor who insists that rooms of dedicated Ordinary Hazard occupancy (storage, janitors, mechanical etc.) within an otherwise Light Hazard occupancy building can be protected as Light Hazard?
NFPA 13 clearly provides direction for adjacent and multiple hazard classifications. I think Chapter 5 and 11 (and common sense) are clear on this. Classroom Labs are even another matter that NFPA has addressed. Do you all run into this "it's all light hazard" belief as well?
