Description

New NFPA 67 provides guidelines to help prevent and mitigate flammable vapor explosions in pipe systems. The first-edition of NFPA 67: Guideline on Explosion Protection for Gaseous Mixtures in Pipe Systems provides a framework for designing, installing, and maintaining piping systems that contain or may contain flammable vapor mixtures. This important document presents the latest best practices used to: Prevent, contain, suppress, and/or vent explosions Avoid Deflagration-to-Detonation Transition (DDT) Contain detonations Minimize damage due to explosions Developed by experts based on industry needs, NFPA 67 is intended to improve industrial fire protection and fire safety. It’s essential for designers, owners and safety managers, insurance professionals, plan reviewers, AHJs, and everyone involved with fire and explosion safety in facilities where piping systems are installed.
