I thought that it was not permitted to reduce means of egress in the direction of egress travel. Is that so or have I misread or perhaps applied Life Safety Code, where I'm pretty sure that is the case.
I'm looking at 6' wide exit door at second floor from an assembly occupancy to a landing, and from landing to grade is a 5' wide stair. Is that allowed?
I'm looking at 1003.6 (2015 IBC) in particular last sentence: "The minimum width or required capacity of a means of egress system shall not be diminished along the path of egress travel."
Maybe my strict interpretation is wrong, but when I look at the classic large loss of life fires and similar crowd incidents, people jammed up at some restriction is a common theme. The 2003 E2 nightclub in Chicago comes to mind. (Yes, many other contributing factors.)
So set me straight if it's ok for 6' doors to lead to a 5' stair. Yes, I think with the 5' stairs there is still sufficient means of egress capacity for the occupant load, barely.
