I’ll also add to Ken’s comment in that much of what FM produces has dependencies on other requirements as well. Building construction, ventilation, etc. can also be part of the specific requirements related to a fire protection data sheet. Read the whole data sheet to be sure there aren’t other requirements outside of your scope that can influence the FP design. Additionally, make sure your local AHJ will accept the design criteria in the FM data sheet if it varies from NFPA. I deal with one jurisdiction that will not accept any FM Data sheet criteria, only NFPA due to NFPA being the only referenced standards in their adopted codes.
Have you looked at Chapter 21, specifically 21.3.2 and 21.3.3?

Quite some time ago I learned from FM Global, that to appropriately use 8-9 as establishing the criteria for protection of storage that the entire fire sprinkler system has to meet FM Global guide documents. It isn't a matter of designing/installing a system per -13 and selecting the protection criteria for storage from 8-9. The system has to conform to all of the FM Global data sheets, beginning with 2-0. sincerely, Ken Wagoner, SET Parsley Consulting 500 West Mechanic Street Harrisonville, Missouri 64701-2235 Phone: (760) 745-6181 Visit the website<https://urldefense.com/v3/__https:/linkprotect.cudasvc.com/url?a=http*3a*2f*2fwww.parsleyconsulting.com*2f&c=E,1,Y5zKJKPEh1mBEBqSR-VE9cUKl5y-eyP8BpvmE_5j9ZqW2eJbNphYzrCMBZ-2YuX6d-RRkHI4gQ1FV-cvOeCfRC58uZS9NiToZv2mx7909oCqLvCW_n5hDHeK&typo=1__;JSUlJQ!!B5cixuoO7ltTeg!DJeai_sUJalxW9YJDfMcmooADU2d3Gm6qqAmmrs7jSnGgO8VggeW61iDcTkfZ9EkBUf6jCSlA-84MBkjZ6qSgg$> On 5/19/2023 10:31 AM, BRUCE VERHEI wrote: For the AHJ types skulking out there, I would back up Scot’s comments, and add the late Joe Hankins to list of highly respected FM P.E.’s. The one comment I do have is that’s #13 is intended to be used as a standard, and 8-9 et al as guidance to FM’s engineers and insured. It much more expects good intent, and is not to be applied for those who go looking for what-if loopholes. We accepted 8-9 all the time, while still applying the seismic etc standards from #13. Best.

I would take my design directions from FM, as most of their high-piled plastic storage advice becomes NFPA 13. Simply FM Global has been leader sin qua non, in sprinkler protection of industrial rack storage for scores-and-more of years. FM Global invokes the Bayesian far more often and far faster than NFPA 13 (i.e. FM Global changes their mind to update their guess when presented with new evidence). While it would appear that FM Global procurement of evidence is biased, because they literally record their own fire test data, I have found the integrity and the personal effort offered by their personnel as a paramount case study in information sharing for the fire safety community. At the risk of tainting their reputations by association with this writer, I can not recommend enough the personal contributions Prateep Chatterjee and Weston Baker of FM Global, have made to our industry. Section 2.2.4.3 of FM Global's Data Sheet 8-9 talks to us on your subject. You are in good care with their share. Collusion exposure statement: Scot Deal has no financial links to FM Global either through payments or client procurement collaborations. Scot Deal is financially linked to NFPA through subscription fees.

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?
