What commodity would you consider hops?
What kind of container will they be in
This specific instance, they are pellets in cardboard boxes on pallets on racks. I'm looking for info on that way and also just bails stacked on top of each other.
My non engineer
non designer thought
Class IV. Maybe III
Same as you would food or any vegetable.
Thanks for the help guys. I was thinking Class III but was looking for other peoples opinions. I have another question, any idea what they were thinking when they did the original design when this room was used for storing bales of hops? Looking through Chapter 14, I can't find anything where they would calculate 25 heads at 7 psi.
I guess you know about design
Well 92 sq ft coverage puts it at ordinary hazard, the sprinkler head is a storage sprinkler, but that high temp rating is throwing me for a loop when it comes to, essentially, dried plant storage... I would call the sprinkler company that installed the system and pick their brain.
My non engineer question
Are they ELO sprinklers
If so how many do you calculate today
And has that number changed since this system was installed
Does FM Data come into play?
The 7 psi is whats throwing me off. I wouldn't think it would be considered ordinary hazard and if they did then shouldn't they have done a density over area method instead of 25 heads at 7 psi? The trouble with calling the original company is they are also bidding on this project and wont share any info with me.
Maybe not designed correctly to begin with??
In these tests, the ELO sprinkler not only performed as well as the older types of sprinklers, but in all but one test, it performed significantly better. In a test at minimum pressure of 50 kPa (7 psi) against a relatively highchallenge storage scenario, its performance was comparable to the original test, but not superior.

I was just told by a coworker than when you raise the temperature rating of the sprinkler heads, you can lower the pressure. Can the company do that? That doesn't seem right. Maybe reach out to the architect?
If you as a fire sprinkler company do not know, the architect more than likely would not know.
I do see different pressures on extended coverage, change coverage area.
Check the most current tech sheet on the sprinkler. If it is not there, it does not happen.
You can call there tech and ask the question
So are they adding more storage building or
Why the question???
They are changing the use from bailed hops to racks with hop pellets in boxes. I'm trying to determine what options they have, like changing the overhead sprinklers or a rack system.
