2019 Edition
Minimize fire and explosion hazards that endanger personnel, facilities, or equipment. Rely on NFPA 86, Standard for Ovens and Furnaces.
NFPA 86 provides the latest comprehensive requirements for the design, installation, operation, and ITM (inspection, testing, and maintenance) of Class A, B, C, and D ovens, dryers, and furnaces; thermal oxidizers; and any other heated enclosure used for processing materials and related equipment.
Help protect people and buildings with updated requirements for:
- General approvals, plans, specifications, and safety labeling
- Location and construction
- Furnace heating systems
- Commissioning, operations, maintenance, inspection, and testing
- Safety equipment and application
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)
