If we are aware that this is a bad practice, and that it will impede or possibly prevent a sprinkler from operating when exposed to a fire in the immediate vicinity of its location, and do not report it as a deficiency, then "we" are gonna get our asses sued off.
A critical deficiency is one that "can have an effect o the performance of the fire protection system." 4.1.4.1 states, "The property owner or designated representative shall correct or repair deficiencies or impairments that are found during the inspection ..." To this comment and Dr. Shane's (welcome to the Viper's Pit, BTW) I would say that this is NOT a theoretical and the question was posed by someone who IS trained and understood in the first place that this was an issue. Don't take my word for it, ask your lawyer.

Plenty in there like foreign materials or in the wrong orientation (because the plate implies it's too far down from the actual ceiling and should be upright based on the BL location, OK, maybe that's weak). You have no idea if it was AHJ approved condition before you got there. If you do as Ron suggested I'd use 5.2.1 as you did a deficient inspection as that section tells you exactly what to look for at the sprinkler, there is foreign material hanging from part of the sprinkler. Don't get me wrong I see where Ron is going for other things that are not mentioned like suspected small pipe size, incorrect density and incorrect spacing. Not sure I agree with Steve's using of the critical definition generically as a trump card for everything. First, some other section must identify what you are looking for then you'd use the definitions to establish an impairment, critical or non-critical deficiency? Is this a deficiency? Yes under 5.2.1. Is it an impairment, no. Is it a deficiency? Yes but I don't know which level as I don't have details. Short room you are probably in the jet and it won't make a difference. Tall space you may be in the plume and might make a bigger difference. In the end I'd never put my name on it as OK. What did you mean they were accepted? Just because an ahj agreed doesn't mean they were ever acceptable by the code. And many moons ago I'm sure there were plenty of AHJ that said no. I seem to only have come across in places that have limited oversight. I've seen them on system's installed in the last 5 years.
