24" wide
AHJ is looking for something in NFPA or FM Global that states that they do not require protection ________________________________ From: Sprinklerforum <[email protected]> on behalf of Steve Leyton <[email protected]> Sent: Wednesday, January 24, 2018 3:50 PM To: [email protected] Subject: RE: Conveyors 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.

My 2¢ 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
