Firestop

So this partition shows mostly all "no rated" walls. Assume that mean no fire rating.
Only parition G is 2 hours rated but that partion is only in very few location.
All other partions seem to be the non rated. Can most of the walls actually be non fire rated?
Thought most walls always had a 1 or 2 hour rating! Thanks.

No walls can be one hour rated, two hours rated or no rating. It depends on the design and where the emergency egress is.

So these partitions, except for G, are not rated?

Look at Note 1 of the firestopping notes.

It shows non-rated, one hour rated and two hour rated. Your firestopping needs to ensure that the rating is maintained based on the wall type.
