DG/TJ 08-88-2021 Design standard for smoke management system in buildings
1 General provisions
1.0.1 This standard is formulated to ensure the rational flow of smoke from building fires, facilitate the safe evacuation of people and the implementation of fire rescue operations, reduce the harm caused by building fires, and safeguard public safety in society.
1.0.2 This standard is applicable to the smoke management design of newly-built, reconstructed and expanded buildings. For the industrial and civil buildings for special purposes or with special requirements, the special requirements, if any, specified in the professional standards, may be followed.
1.0.3 The smoke management design of buildings shall take into account the characteristics of the building and the development laws of smoke during a fire, and adopt reliable smoke management measures to ensure safety, applicability, advanced technology and economic rationality.
1.0.4 When new technologies, new equipment and new materials are adopted in the design of smoke management system, reasonable technical basis shall be put forward.
1.0.5 The design of smoke management system, in addition to meeting this standard, shall also meet the current relevant national, professional and municipal standards.
