Mitigate static electricity hazards. Help prevent ignition of flammable vapors, dust, and particulates by grounding and bonding according to the best practices in NFPA 77.

A buildup of static electricity can be a considerable hazard — it can discharge in air and ignite flammable vapors and dust. NFPA 77, Recommended Practice on Static Electricity provides important information on evaluating and controlling static electric hazards to help protect those working where these hazards can be present.

NFPA 77 offers guidance on how to:

  • Eliminate static electric charges by bonding and grounding.
  • Manage static electricity where ignitable dusts or vapors are present.
  • Manage the flow rates and flow velocities of liquids when they are transferred.

This recommended practice covers industries as diverse as chemical processing, petroleum refining, printing, and calendaring. It includes answers to questions about properly bonding and grounding a container, and how to determine whether a static electricity hazard poses a risk.

The 2019 edition of NFPA 77 is up-to-date with referenced documents and the latest safety knowledge including:

  • Updates to reference documents, Chapter 2, and Annex I reflect current editions.
  • Changes to the definitions for combustible dust and grounding reflect the use of the terms specific to NFPA 77.
  • Changes to the characterization of low, medium, and high resistivity powders in Chapter 15 reflect generally accepted international standards.

Grounding and bonding with NFPA 77 as a guide is essential to safety in many industrial environments. (Softbound, Approx. 67 pp., 2019)

A buildup of static electricity can be a considerable hazard, as it can discharge through the air and ignite flammable vapors and dust. NFPA 77: Recommended Practice on Static Electricity provides important information on evaluating and controlling static electric hazards to help protect those working where these hazards might be present.

NFPA 77 offers guidance on how to:

  • Eliminate static electric charges by bonding and grounding.
  • Manage static electricity where ignitable dusts or vapors are present.
  • Manage the flow rates and flow velocities of liquids when they are transferred.

This Recommended Practice covers industries as diverse as chemical processing, petroleum refining, printing, and calendaring. It includes answers to questions about properly bonding and grounding a container, and how to determine whether a static electricity hazard poses a risk.

NFPA 77 has been updated to reflect some important changes:

  • It has been completely reorganized by dividing some of the chapters into smaller, more cohesive units.
  • In Chapter 5, the descriptions of the mechanisms by which static electric charges are formed have been simplified.
  • The section on flexible intermediate bulk containers (FIBCs) has been completely rewritten to comport with international standard IEC 61340-4-4, Standard Test Methods for Specific Applications — Electrostatic Classification of Flexible Intermediate Bulk Containers.
  • The section on static electric hazards in bulk storage tanks has been completely revised to incorporate international standard IEC 60079-32, Explosive Atmospheres — Part 32.2: Electrostatic Hazards.

To prevent ignition of flammable vapors, dust, and particulates, you’ll need to get your hands on the gold standard of static electricity safety. Order NFPA 77 today.

Prevent fires and explosions with proper identification and control of static electricity using NFPA 77.

In addition to being a danger to individuals and an operating problem in industry, static electricity is often the ignition source for an ignitable mixture. Guard against fires and explosions using the latest best practices outlined in NFPA 77. You’ll access clear guidelines for the assessment of ignition potential and protocols for fire prevention.

Use NFPA 77 to mitigate risks. This document covers:

  • Hazards of static electricity
  • How to control ignition hazards
  • Flammable and combustible liquids
  • Dusts and fibers
  • Gases
  • Industrial and commercial processes
  • Detection and measurement of static electricity

Important updates in the 2007 edition:

  • Recognition of positive ground indicators or self-testing ground clamps where indicated by environmental conditions
  • Revised guidance on static neutralizers that use a high-voltage power supply

The document is also reorganized for clarity and consistency with NFPA’s Manual of Style.
