Can any one gives me example for Convenience Openings as I cannot understand/ differentiate it from the communicating spaces....for ex, if I have a study room that has an inner floor opening to the  the living room below then it is a communicating space but If I added a stair within this opening then it turns into Convenience Openings?

what are the uses for the Convenience Openings other than open staircase or escalator?

ex. If I got an Hotel occupancy where is not allowed, however the designer want to use a Convenience Openings stair case between the lobby and the upper level (only one floor pierced) then can I use which is permitted by the code... what if he wants the st,case to connect  3 levels, can I put it in an 1 hr fire rated enclosure  with self closing doors and deal with it like a shaft?
