Egress from Corridor Through Another Room?

12/20/2019

Are there any scenario where the means of egress can be routed from a corridor, through a room, to the exterior? Must all egress corridors discharge to the exterior?

I would assume panic hardware would have to be provided and the room couldn't have a means of being locked, but if a room is relatively low-hazard (like a classroom) could it be used for egress between a corridor and the exterior?

See if IBC 2018 Section 1016.2 "Egress through intervening spaces" answers your question

Rather see the exceptions to 1020.6.

If the corridor is rated, then the rating needs to continue to the exit discharge. You can have exit accesses go into a room of equal or lesser hazard, but if it is indeed required to be a rated corridor, then the room would also need to be rated.

You can always have a corridor dump into a vestibule, lobby, or large open office as long as it complies with the section noted by others above.

You can not dump a corridor into a breakroom, for example, but you could dump it into a changing room/airlock if the area the corridor serves is coming from a cleanroom. As noted above, the corridor rating must be maintained with little exception.

I would have to disagree with your statement that one cannot dump a corridor into a break room, According to the folks at ICC, a break room is a area that has only a microwave oven, refrigerator and coffee dispenser. I believe you were referring to a commercial kitchen which is not allowed by code.
