NFPA 91 Standard for Exhaust Systems for Air Conveying of Vapors, Gases, Mists and Particulate Solids
NFPA 91 Standard for Exhaust Systems for Air Conveying of Vapors, Gases, Mists and Particulate Solids 2020
Help ensure compliance with critical requirements for safeguarding potentially dangerous exhaust systems from fires and explosions.
This code represents the most complete criteria for designing, constructing, installing, testing, operating, and maintaining these systems.
This vital safety document assists in protecting lives and property and minimizing loss from fires and explosions in exhaust systems where vapors, gases, mists, and particulate solids are present in the airflow. The standard incorporates provisions on the application of exhaust systems to specific industries or operations from NFPA 1, Fire Code, NFPA 30, Flammable and Combustible Liquids Code, and many other codes and standards.
Update to the 2020 edition to access the most current information and performance criteria.
The revised NFPA 91 provides the latest knowledge on exhaust systems for air conveying vapors, gases, mists, and particulate solids relating to fire and explosion prevention. Content covers everything from requirements for corrosive materials and air-moving devices to air-material separators, ignition sources, and fire protection systems.
Changes to the 2021 edition include added requirements for nonconductive system components and revision to the concentration threshold for flammable or combustible materials requiring spark-resistant fans and blowers.
NFPA 91 is an essential resource for process industries with ignition risks of materials pneumatically conveyed through duct systems.
It is critical design and fire protection engineers, safety and health professionals, industrial hygienists, or fire and building officials have access to the most relevant codes and standards.
