All vertical openings between stories, such as stairways, elevators, light or ventilation shafts, should be enclosed, and their construction should have a 2-hr fire resistive rating.

CONT

Protection of vertical openings. Most department stores have vertical penetrations that weaken the vertical system of fire barriers. These vertical penetrations usually consist of a combination of stairways, elevator shafts, and numerous escalator openings. The NFPA [National Fire Protection Association] Life Safety Code requires stringent protection for these vertical openings, especially if they are part of a means of egress.
