Corridor question

My bottom line I think is

If you have a non sprinkled building

A corridor

An occupant load of 30 using that corridor

You cannot say 15 will go one way and 15 will go another way

There for I do Not have to rate the corridor

You do.

It serves 30


Agreed...sort of, but if you have a single story 2 exit required building that has a waiting room with an occupancy of 30 with exit directly to the exterior, I interpret you would not add 30 occupants to the corridor to access the 2nd bldg exit. This interpretation is in line with the the exception to classrooms with doors to exterior where in a building that requires 2 exits you can say the kids will go this way...
 
In a non-sprinklered building the rating of the corridor is not determined by how many exits there are from the corridor or the building. It is determined by how many people will be using the corridor. If 2 exits are required you have to add 1/2 the waiting room OL to the corridor they will be forced to use. If the accumulative number exceeds 30 then it has to be rated
 
To be clear... the Code does not require any occupant to go in any particular direction to any particular exit.
What the code requires is that where there are more than one exit, the loss of any one exit will not reduce the total capacity by more than 50%.
That does not require half the occupants to go one way or the other, it simply ensures that if any one exit is compromised that the remaining exit(s) will be able to handle the occupants egressing from the space.

Best explanation during this political year I have heard.
 
Can someone please explain to me the fire door requirements in a sprinkled building or where I can find that information? I'm looking for the actual code telling me what the doors should be rated in a particular rated wall and how it breaks down.

Which edition and building code do you want referenced

The answer can vary

Normally worse case scenario 20 minute door.

Where corridors are not rated, can have any type door to no door at all
 
The wall rating may change based on sprinklers but the opening protective rating is driven off of the wall rating...And I believe all rated walls need rated OP....At least 20 min.
