NFPA 204-2021 PDF Download

The NFPA 204-2021 standard aims to prevent the accumulation of products of combustion within buildings. It provides guidance for engineers and enforcers on the design of venting systems for emergency venting of smoke and heat. The standard covers various aspects related to smoke and heat venting, including fundamentals, vents, air inlets, draft curtains, fire design, sizing vents, mechanical smoke exhaust systems, venting in sprinklered buildings, inspection and maintenance, and design documentation.

The standard offers both manual calculation and computer-modeled solution methods to aid in design and determine the necessary tools for vent designs based on specific performance objectives. The NFPA 204-2021 edition includes revisions to align it with other NFPA codes and standards. For example, it removes the requirements for sprinkler waterflow activating automatic smoke vents and adds SI unit conversions in Annex C. Engineers, architects, facility managers, and inspectors can utilize NFPA 204 to enhance fire protection in buildings with smoke and heat venting systems and ensure their proper maintenance and functionality.
