We have a completely open exit access stair in a type II-A classroom building. It is egress stair. II-A requires the floor and secondary framing to be 1 hr but there is no fire rating required for exit access stair. I read some former posts debating whether the stair framing is primary or secondary structural member. Seems everyone agrees it is secondary. If so, the stair FRAMING has to be 1hr rated? Our stair is steel stair, will the whole run needs to be rated?
If it is not required to be rated, then it seems weird the 2nd floor rating stops at an opening? should not the stair be the continuation of the floor?
Logic wise, the egress components always need to be protected. so why not exit access stair?
Please help me out.
