That's what I was alluding to and in the past 6-7 years this has been my experience exclusively. Automation = efficiency and the accountability that you describe. I've been in 500K-1MM sq. ft. buildings that are so clean you could literally eat food off the floor. I guess it's relative though and the letter of the code says that you have to account for obstructions. These are described as 30" AFF so I'm not sweatin' it, but most of the buildings we've worked on have mezzanines and elevation changes where belts angle up and down. Still, with sprinkler protection under platforms and ESFR overhead, the "obstruction" potentially posed by 24" conveyors on the floor is effectively nonexistent.

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.

My 2ยข and nothing more, Steve L. From: Sprinklerforum [mailto:[email protected]] On Behalf Of Mike Hairfield Sent: Wednesday, January 24, 2018 12:40 PM To: Sprinkler Forum Subject: Conveyors 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, Mike Hairfield
