Ken - so you feel my pain? I am in Canada so we don't use IFC, but thanks for the reference anyway.
My FM reference was from the 2013 edition of FMDS 8-1. I just looked at the 2015 edition of FMDS 8-1 and 2.3.8.3 and Table 1. 2.3.8.3 "in general, plastic storage containers drive the fire protection.". Table 1: - container with solids inside, - container with solid sides and bottoms, - container volume >1 gal, and - non-combustible contents. Commodity = uncartoned, unexpanded plastic (UUP). Great way to start a long weekend....

According to figure 3203.7.4 (2012 edition of the IFC), if the commodity you're dealing with has less than 15% of expanded plastics, measured by weight, it should be classified as a Class IV. If the percentage, again, by weight, drops to less than 10%, it would be a Class I-III. I don't disagree with your referencing NFPA 13, and classifying it as a Group A. I am having a bit of difficulty with your reference to the FMDS 8-1. My version, April/October 2014, doesn't have a section 2.2.7.1.2.3, as section 2.2 stops with 2.2.2. However, FMDS 8-1, in section 2.3.5.1, advises that if the weight of the unexpanded plastics is less than 5% of the pallet load, it could be designated as Class IV. If greater than 5%, it would be unexpanded plastic. Conflicting documents like this is why I have a large stock of antacid tablets. *Ken Wagoner, SET *Parsley Consulting*** *350 West 9th Avenue, Suite 206 *Escondido, California 92025 *****Phone 760-745-6181* Visit our website <http://www.parsleyconsulting.com/> *** On 07/31/2015 11:33 AM, S & C Conlin wrote: > I considered it a GR A because of the example in NFP-13, Table > A.5.6.4.1 of the non-combustible solid in a plastic container. > As a matter of information, FMDS 8-1, 2.2.7.1.2.3, would consider this > commodity as a Gr A. > > -----Original Message----- > From: Sprinklerforum > [mailto:[email protected]] > On Behalf Of Morey, Mike > Sent: July-31-15 2:10 PM > To: [email protected] > Subject: Re: Exposed Nonexpanded Plastic Container > > Based on the description it seems like the plastic is packaging, and > it would fall under 5.6.3.3.2 and 5.6.3.4.1 (NFPA 13 2013) > potentially, in which case it would be Class III or IV? > ________________________________________ > From: Sprinklerforum <[email protected]> > on behalf of S & C Conlin <[email protected]> > Sent: Friday, July 31, 2015 1:52 PM > To: [email protected] > Subject: Exposed Nonexpanded Plastic Container > > Involved with this project where the warehouse and the palletized > storage areas contain skids of exposed plastic pails containing > non-combustible solids.
