B3.2.7 Hotels with 2 stories (or more) above ground floor should be equipped with a minimum of 2 escape staircases which are physically separated from each other by fire resisting construction. This is so that if one stair cannot be used because of the fire, then the other stair will still be available. Stairways should be protected, safe to use, and preferably lead directly to a final exit (see B3.2.4 above).
