Keeping It Simple:Smoke Control In Hospitality Occupancies
These concepts are incorporated by designers and confirmed by building officials. The systems noted address most life safety concerns in residential occupancies. Smoke control systems may also be required for residential occupancies in high-rise buildings, or in buildings involving unique features such as atria or other atypical designs. Atypical features may introduce hazards that warrant the additional complexity of automatic controls generally associated with smoke control systems.
In special cases, additional protection may be appropriate due to limited fire department access, longer exit times in larger buildings, and the increased exposure to those exit ways from fires or other hazardous conditions. When exit ways are threatened by other building features, or when the occupants may have a more extreme exposure due to longer required exit times, additional systems or features are appropriate to increase the level of protection to the occupants and compensate for the increased hazards.
