Where are sprinklers required in vertical shafts, stairways, elevator equipment rooms and elevators shafts? The special situations included in NFPA 13 sections 8.15.2, 8.15.3, 8.15.4 and 8.15.5 will be reviewed. NFPA 13 requires sprinkler protection in vertical shafts having exposed combustible construction. The basic requirements for installation of sprinklers, considerations for inspection and conditions allowing omission of protection in vertical shafts will be identified. Sprinkler protection requirements for stairways of combustible, limited combustible and noncombustible construction will be identified. Situations involving vertical openings for escalators, staircases and atriums will be reviewed. Sprinkler protection requirements for elevator equipment rooms and shafts will be identified. These requirements have evolved over the last several cycles and reviewed to demonstrate when sprinkler protection is required and when it can be omitted.
