The tape material is PET and the cases are unexpanded polystyrene. Both are listed in NFPA 13 as Group A plastics.
In one section of NFPA 13, the magnetic tape alone is listed as a Class IV commodity but that does not include the casing of a VHS or cassette tape. Craig L.

I read an interpretation that says that the VHS tapes can be considered Class IV rather than Group A plastics. I can't find anything in 13, 232, IBC, or IFC that corroborates this. Can anyone verify this or give me direction? This is in an existing sprinklered building that was originally calc'ed for LH. Somewhere over the years the area was converted from a small library that was open to a common office area to a closed off compartment. Any help will be appreciated.
