Prevent deflagration explosions due to combustible dust particles, gases or vapors with NFPA 69.

Combustible dust, gases and vapors produced in industrial settings can pose a significant safety hazard. NFPA 69: Standard on Explosion Prevention Systems offers definitive guidance on explosion protection and prevention systems.

This document is applicable to woodworking, grain processing (including sugar) and machining facilities, where combustible dust can spark explosions. It also covers facilities in which flammable liquids are used or petrochemical processing takes place — and explosions due to combustible gases or vapors are a concern.

NFPA 69 has widespread applicability. Among the equipment protected are pipes, ductwork, vents, dust collection systems and granaries. In addition, systems for explosion prevention, explosion isolation, oxidant concentration control, fuel concentration control and ignition control are all designed in accordance with this standard.

The 2014 edition of NFPA 69 features:

  • Easier-to-understand explanations
  • Compatibility with NFPA 3: Recommended Practice for Commissioning and Integrated Testing of Fire Protection and Life Safety Systems terminology and other standards
  • Updated references and abstracts
  • New requirements for flow-actuated flap valves
  • A new annex on deflagration containment for two interconnected vessels

It also provides valuable insight on:

  • Installing an explosion isolation valve or system
  • Designing equipment to contain an explosion
  • Controlling your process to ensure an explosive atmosphere doesn’t develop
  • Installing an explosion suppression system
  • Controlling ignition sources in your process before an explosion occurs

NFPA 69 is an essential resource for system designers, safety officers, insurers, municipal and state inspectors, and other professionals.

Apply NFPA 69 to help prevent explosions due to combustible dust particles, gases, or vapors.

Combustible dust, gases, and vapors produced in industrial settings can pose a significant safety hazard. NFPA 69, Standard on Explosion Prevention Systems, offers definitive guidance on explosion protection and prevention systems.

This document is applicable to woodworking, grain processing (including sugar), and machining facilities, where combustible dust can spark explosions. It also covers facilities in which flammable liquids are used or petrochemical processing takes place — and explosions due to combustible gases or vapors are a concern.

Protected equipment includes pipes, ductwork, and dust collection systems.

Systems for explosion prevention, explosion isolation, oxidant concentration control, fuel concentration control, and ignition control are all designed in accordance with NFPA 69, which is also compatible with the terminology of NFPA 3, Recommended Practice for Commissioning and Integrated Testing of Fire Protection and Life Safety Systems, and other standards.

Essential for system designers, safety officers, insurers, municipal and state inspectors, and other professionals, NFPA 69 provides valuable insight on:

  • Installing an explosion isolation valve or system
  • Designing equipment to contain an explosion
  • Controlling your process to help ensure an explosive atmosphere doesn’t develop
  • Installing an explosion suppression system
  • Controlling ignition sources in your process before an explosion occurs

Changes in the 2019 edition include:

  • A revised adjustment for Limiting Oxygen Concentration (LOC) values obtained in flammability tubes, reconfirming a change made by a TIA
  • New requirements that consider the concentration variation with time and location within the protected enclosure — as well as variations in operating conditions and material loadings — when using the combustible concentration reduction method of explosion prevention
  • A new section on Safety Instrumented Systems (SIS), along with a requirement that explosion prevention system controls installed after November 5, 2021 be implemented as an SIS
  • Added annex material that provides example calculations on how to estimate the LOC for a fuel or a fuel mixture

Head off explosions with the field’s best guidance as defined in the 2008 NFPA 69.

NFPA 69 applies to the systems and equipment used for the prevention of explosions by the prevention or control of deflagrations.

The 2008 edition incorporates the following changes:

  • Added and updated definitions essential to characterizing deflagration hazards. All definitions were reviewed to be consistent with other NFPA® documents.
  • Two new chapters have been added to incorporate a performance-based approach for compliance, in addition to the more traditional specification-based option.
  • The concept of safety integrity levels (SIL) for safety instrumented systems was added to the standard to address aspects of system reliability.

Chapters on Detection and Ignition Control and Suppression were updated and expanded. Requirements for explosion prevention control by isolation were expanded in two chapters – one on passive isolation techniques and another on active techniques. A new chapter on passive suppression using expanded metal mesh or polymer foam has also been added.

A new chapter on Installation, Inspection and Maintenance consolidates all relevant requirements in one place.
