My completely non scientific input: we’ve done a few warehouses with mattresses albeit mostly in bags, and no one has ever argued it (in fact it’s usually called out as expanded exposed). I suppose if they vacuum and cram it tight enough it’s at least temporarily not expanded anymore but I don’t think that’s a legitimate argument since the packaging will fail in a fire.

ZjQcmQRYFpfptBannerEnd I’m working with a client who wants to store mattresses in racks. They are foam mattresses, so these would be group A expanded plastics (EP). Each of the mattresses is rolled up and packaged in a cardboard box. So, cartoned expanded plastics (CEP), right? The customer (who is very knowledgeable about the mattress manufacturing process and requirements) wants to argue that mattresses should not just automatically fall into the “High-hazard (Group A Expanded)” category because of the strict flammability standards that mattresses are legally required to meet, specifically CFR 1633 – Standard for the Flammability (Open Flame) of Mattress Sets. What are your thoughts on this? I have my own ideas, but I was wondering if anyone had gone down the path before. Do you think the client’s assertion has merit? Why or why not? Thanks.
