This Standard sets minimum requirements for the design of smoke control systems in large single compartments in which smoke accumulates in a smoke reservoir. It sets minimum requirements considered necessary to meet the system design objectives in terms of continuous operation over a specified time period under a specified fire condition. The design information given in This Standard is based on axisymmetric plumes. Compartments and smoke reservoirs are designed separately and spill plumes between compartments/reservoirs are not considered. Application of this Standard is not appropriate in situations where a stable buoyant hot layer does not exist.
