    Changes in the 2019 edition of NFPA 86 make the standard easier to understand and apply:

    • Added definitions for open and closed cooling systems, along with corresponding changes to furnace design in Chapter 5 Location and Construction, keep the document up-to-date with industry today.
    • Clarified explosion relief exceptions in Chapter 5 Location and Construction reduce the risk for misinterpretations.
    • Revised requirements for radiant tubes reflect performance-based criteria rather than material-based criteria.
    • Revised requirements for emergency switches allow for flexibility in cases where a full system power-down creates unintended hazards (e.g., in some Class C furnaces).
    • Added Annex table for relighting without purging clarifies the requirements in Chapter 8 Safety Equipment and Application.

    NFPA 86 gives industrial facility owners and operators, designers, and installers confidence in fire safety and fire protection for ovens, furnaces, dryers, thermal oxidizers, or other heated enclosure for processing of materials. (Print, 168 pp., 2019)

    • Added procedures for placing equipment into service based on purging practices in the 2015 NFPA 54, National Fuel Gas Code and the 2014 NFPA 56, Fire and Explosion Prevention During Cleaning and Purging of Flammable Gas Piping Systems
    • New requirements prohibiting the manifolding of vent lines from different pressure levels
    • Modified requirements for Class A and Class C ovens and furnaces -- including the development of new requirements on fire protection and safety ventilation for Class A ovens.

    NFPA 86 gives industrial facility owners and operators, designers, and installers confidence in fire safety and fire protection for ovens, furnaces, dryers, thermal oxidizers, or other heated enclosure for processing of materials. (Softbound, 141 pp., 2015)
