The provisions of Chapters 4 through10 shall apply to the design of venting systems for the emergencyventing of products of combustion from fires in nonsprinklered,single-story buildings using both hand calculationsand computer-based solution methods as provided inChapter 9. Chapter 11 shall apply to venting in sprinkleredbuildings.
Click here to purchase Apply NFPA 204 for smoke and heat venting systems that work effectively to prevent build up of combustion products.
Engineers developing fire protection schemes and enforcers charged with plans approval need NFPA 204: Standard for Smoke and Heat Venting, featuring critical requirements and additional information addressing design of venting systems for the emergency venting of products of combustion from fires in buildings.
Requirements cover:
Fundamentals, including design objectives, design basis, and determination of contents
Vents
Air inlets
Draft curtains
The Design Fire, including steady (limited-growth) fires and growing (continuous-growth) fires
Sizing vents
Mechanical smoke exhaust systems
Venting in sprinklered buildings
Inspection and maintenance
Design documentation
The Standard’s manual and computer-modeled solution methods aid in design calculations. The equations or models provide the designer with the necessary tools to develop vent designs based on selected performance objectives related to a specific building and a specific set of circumstances.
Revisions keep the NFPA 204 consistent with other NFPA® codes and standards.
In addition to updated references, the 2018 edition also includes a correction to an Annex A image and a change to definitions. Engineers and architects use NFPA 204 to improve fire protection in buildings where smoke and heat venting is used. Facility managers and inspectors also rely on NFPA 204 to ensure systems are maintained so they can function as designed.
Following the updated guidelines in the 2012 NFPA 204 to correctly design and maintain smoke and heat venting systems.
The 2012 NFPA 204: Standard for Smoke and Heat Venting applies to the design of venting systems for the emergency venting of products of combustion from fires in buildings. Manual and computer-modeled solution methods aid in design calculations. The equations or models provide the designer with the necessary tools to develop vent designs based on selected performance objectives related to a specific building and a specific set of circumstances.
This latest edition introduces new rules for venting systems in sprinklered buildings, including:
The venting system design must be based on an engineering analysis
Automatic sprinkler systems must comply with NFPA 13: Standard for the Installation of Sprinkler Systems
