Any adjacent walls where records such as paper, media, etc. must have a two-hour minimum fire rating.
There are different regulations that exist for external walls from state to state.
Incorrect Answers:
A: Walls to adjacent rooms where records such as paper and media are stored should have a two-hour
minimum fire rating, not a one-hour fire rating. Therefore, this answer is incorrect.
C: It is not necessary for all walls to have a two-hour minimum fire rating. Therefore, this answer is incorrect.
D: It is not necessary for the internal walls to have a two-hour fire rating and it is not necessary for walls to
adjacent rooms where records such as paper and media are stored should have a three-hour minimum fire
rating. Therefore, this answer is incorrect.
