Good Morning In the NFPA 13 2016 handbook commentary it says " ESFR sprinklers are limited to being able to protect solid-piled and palletized storage. Bin box and shelf storage cannot be protected by ESFR sprinklers because the solid nature of the bin box and shelf arrays blocks water discharge from the sprinklers from reaching the seat of the fires originating in bin box and shelf units. For protection of bin box and shelf units spray sprinklers with density / area protection criteria much be used in accordance with Section 15.2" .
I hope this helps [cid:[email protected]] From: Steve Leyton <[email protected]> Sent: Thursday, May 18, 2023 5:47 PM To: [email protected] Subject: [Sprinklerforum] Plastics in Bin Box storage You don't often get email from [email protected]<mailto:[email protected]>. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> I want to be sure that I've got this right: A client is moving into a brand-new ESFR protected warehouse space and they want to build a two level bin-box system. I explained that they would have to fire protect below the walkways and they've come back to me asking whether or not building just the lower level of the system would alleviate the need to make sprinkler system improvements. The CMSA and ESFR protection tables in Chapter 14 (2016 edition) don't include bin-box or plastics in the application range, Only palletized and solid pile, Classes 1-4. If they want to use a bin-box system, do they have to change roof sprinklers out for CMDA? Or can the ESFR remain and CMDA sprinklers would be installed under walkways when they're built? I miss the little bitty book and pipe scheduled systems...
