In buildings with more than three storeys above the ground storey, stairs may serve the flats and other occupancies if all of the following apply.
a. The flat is ancillary to the main use of the building.
b. The flat has an independent alternative escape route.
c. The stair is separated from occupancies on lower storeys by a protected lobby (minimum REI 30) at each of those storeys.
d. The stair enclosure has at least the same standard of fire resistance as the structural elements of the building (see Appendix B, Table B4); if the stair is a firefighting stair, it should comply with the provisions in Section 15 (see also paragraph 3.60).
e. Any automatic fire detection and alarm system fitted in the main part of the building also covers all flats.
f. Any security measures in any parts of the building do not prevent escape at all material times.
