Hi all - I am currently reviewing an ESFR sprinkler protection of compressed, rolled-mattresses in cartons.
During a fire, once the carton burns, the mattresses will be able to retrieve, at least partially, its initial uncompressed configuration. Considering this, I'm skeptical about it being classified as a cartoned unexpanded plastic.
It seems to me that the proper classification should be cartoned expanded plastics, as I've found nothing justifying this optimistic opinion.
Do you have an opinion on how this should be properly classified, or how you would view it?
I'd love to hear about your point of view on the subject and choices made for similar projects.
Thanks and regards.

Ultimately it depends which type of foam is used to make your mattress.

Also worth noting in Table A.188.8.131.52 (NFPA 13 2016 edition) is that "Mattress; foam (in finished form)" is also noted as an Expanded plastic.

As you said, and I agree:

I agree with the others. I'd definitely treat this as cartoned / expanded.

While it maybe stored compressed during a fire I would expect it to burn like an expanded plastic.

You can compress it as much as you want, an expanded plastic remains an expanded plastic (mainly because of its chemical characteristics, not only because of the possible amount of air trapped).

I agree with the others. When you have a fire it will quickly become exposed expanded,
