Chris - there are a couple issues: 1. This was part of an inspection? If done per NFPA 25, you would not be evaluating the adequacy of protection - though as been suggested many times on this Forum, you may consider a separate note apart from the inspection forms indicating a concern that there may be an issue. I would suggest you recommend an evaluation by a qualified engineer. You've addressed a concern without declaring a position (a task for which you were not hired).
2. Ignoring 'why' you were able to see this arrangement, the answer to your question could very well be, 'yes, they need to add in-rack sprinklers.' Let's look at an extreme case: You have a warehouse of metal parts storage solid piled, with single row racks of expanded plastics to 20 ft. along the exterior walls. Certainly we can see that OH2 is inadequate for the plastics so in-racks would be needed (maybe even a higher density at the ceiling). Your case, while maybe not as stark a contrast in storage, isn't really different. It all depends on the shelving methods, storage heights, and the actual commodity classification of the misc. storage in those racks. But you very well could have a situation where one single-row rack requires in-racks. Mark A.

I noticed in a few areas they have installed on single rack against the outside wall with misc storage stacked at various heights. I have never seen one independent rack sprinklered but it looks like to me it should be. Has anyone ran into this before? What did you do?
