Greg said, "So regardless of light or ordinary hazard". The obstruction criteria for Vertical Obstructions can only be applied to Light Hazard. Therefore, I don't believe that you can apply it to the storage compartments. Maybe what you are saying is that if you position a sprinkler directly over top of a partition wall than it could be 7' either direction to the next wall and not be affected? Otherwise, the shadowing created by the vertical obstruction would be huge and the ability of the sprinkler to adequately control the fire would be greatly reduced due to the potential fuel load in any given storage compartment.
Anyway, just my two cents for the day, Bob Knight -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Chad Sent: Wednesday, February 10, 2010 11:45 AM To: [email protected] Subject: RE: Floor Mount Vertical Obstructions So the chart for Light Hazard occupancy shows that if the vertical distance is 18", than the sprinkler has to be 30" or more from the vertical obstruction. So regardless of light or ordinary hazard, you can ignore the vertical obstructions if they are greater than 18" down? So If you can ignore the vertical partitions due to them being greater than 18" below, you can also ignore any horizontal spacing to the partitions. You could end up with a sprinkler horizontally 7' off of two walls of the individual cubical. Therefore, the s x l would not apply to each individual cubical, since theoretically, there are no partitions. Correct?
