NFPA® 67, Guide on Explosion Protection for Gaseous Mixtures in Pipe Systems gives designers, engineers, contractors, installers, and facility managers invaluable support for better ensuring safety in any facility with piping systems that may contain flammable gases where there is potential for ignition. It's an essential resource for anyone who works with process piping, vapor recover system piping, gas venting piping and manifolds, gas piping for water electrolysis and fuel cell systems, flare systems, and other types of piping systems.

Design, install, and operate explosion protection systems for piping, using the latest practices developed by experts to:

• Prevent, contain, suppress, and/or vent explosions
• Avoid Deflagration-to-Detonation Transition (DDT)
• Contain detonations
• Minimize damage due to explosions

The 2019 edition of NFPA 67 provides broader coverage.

• All-new text identifies and addresses three additional applications where there is potential for flammable gas formation.
• A new annex provides examples of applying the equations for suitable pipe wall thickness for pipe wall elastic response to stable detonations.
• Important clarifications make the Guide easier to understand and apply.

NFPA 67 is an important resource for everyone involved with fire and explosion safety in facilities where piping systems are installed.
