Why would you want to omit the OV, most staircases, if not all, will have windows, ensure they have sufficient opening windows. simples!

All my responses only apply to England and Wales and they are an overview of the subject, hopefully it will point you in the right direction and always treat with caution.

Tom, sometimes the layout doesn't have any external walls available around the stairway, e.g. sometimes the stairway is against  a party wall and the flats are planned around the available external walls, or the windows are too small. Sometimes town planning problems like listed building status. The design might be fairly advanced before the designer becomes aware of the recommendation for OVs in ADB.

Not sure I go along with that Colin - what else might have been missed?
Are any of the following an option- vellux, louvre vent in roof, smoke shaft through void, fan (which can be calculated and be much smaller than a natural vent? )

The SVA and Colt do a lot of free documents which may provide a solution.
