There are numerous occupancies with conveyors with numerously different 
cleanliness standards and numerous different types of material being handled.  
Not every place fits into this nice neat tiny little box you describe.

[Tangent Alert] With regard to common sense, for most of these large 
fulfillment centers their entire livelihood is based upon knowing exactly where 
every package/product is at all times. What is the likelihood that they would 
just throw a few packages under the conveyor, or let debris accumulate? I 
realize that this isn't addressed in the code, but it should be considered when 
you're talking about the prospect of adding hundreds of sprinklers under small, 
floor-mounted conveyors. In most cases 99.9% of those sprinklers spend their 
lives protecting concrete.

Same section number.   Plus there's no storage below.  And common sense.

24" wide



AHJ is looking for something in NFPA or FM Global that states that

they do not require protection

Oops - they're not 30" wide, they're 30" AFF.  So how wide are they?  I've 
worked on some giant FC projects but the conveyors weren't 48" in any case.

Considering that the fire load that we want to protect is being conveyed with 
full exposure to sprinklers above, and it's not practical in distribution and 
fulfillment center operations to store combustibles under such belt systems, I 
can't imagine why you'd need sprinklers below a 30" conveyor even if it wasn't 
open.



My 2ยข and nothing more,

Here is my question:



ESFR Systems that have some roller conveyors at 30" AFF that the the opening 
between rollers

is over 50% do they require sprinkler protection under them?



It use to be that they were not required to be protected!



Thanks,
