NFPA 92-2021 PDF Download

NFPA 92 is a comprehensive standard that focuses on smoke control systems and aims to ensure that these systems effectively manage smoke in the event of a fire. It combines the requirements of previous standards, NFPA 92A and NFPA 92B, and covers various types of systems used to address the impact of smoke, including their design, installation, and testing.

The 2021 edition of NFPA 92 features several revisions. Some chapters have been updated for clarity, such as the requirements for door design numbers and the number of doors open during testing. Additionally, new annex material has been added to assist professionals working with systems with makeup air velocities exceeding 200 ft/min. Equations and values throughout the standard have also been updated to accommodate SI (metric) users.

The chapters in NFPA 92 cover a range of topics, including design fundamentals, smoke management calculation procedures, building equipment and controls, smoke control system documentation, and testing. The standard also provides extensive explanatory material, featuring tables, charts, and state-of-the-art calculations. It offers guidance on topics such as predicting the rate of heat release of fires, computer-based models for atria and malls, additional design objectives, smoke stratification, types of stairwell pressurization systems, and HVAC air-handling systems.
