Liquidtight Flxible Metal Conduit (Plenum rated?)

[bdktoys]

I can't seem to find whether Liquidtight Flexible Metal Conduit can be use in a plenum space. I did see that it is suitable under raised computer room floors. But that doesn't mean that it is a plenum space.
Can anyone please advise.

Most of what are called "plenum" spaces are 300.22(C) spaces. LFMC is not a permitted wiring method for 300.22(C) spaces. See 300.22(C)(3) for the permitted wiring methods.
