2019 NFPA 77 Recommended Practice on Static Electricity

NFPA 77, Recommended Practice on Static Electricity 2019 edition provides comprehensive guidance on evaluating and controlling static electricity hazards in industrial environments. Coverage addresses the mechanisms of static charge generation and accumulation, hazard assessment methodologies, and grounding and bonding practices for preventing electrostatic discharge from igniting flammable vapors, combustible dusts, and particulates. The guide is widely used in chemical processing, petroleum handling, powder and bulk solids operations, and other industries where electrostatic ignition risk is a primary safety concern.

Important Note on Document Type

NFPA 77 is a recommended practice, not a mandatory code. It provides guidance and best practices rather than enforceable requirements. Consult your applicable regulatory framework to determine mandatory grounding and bonding requirements for your specific operations.

Who Uses NFPA 77

Used by process safety engineers, industrial hygienists, electrical engineers, fire protection engineers, and EHS professionals responsible for electrostatic hazard assessment and control in facilities handling flammable liquids, combustible dusts, and powders.

What's New in the 2019 Edition

• Updated reference documents in Chapter 2 and Annex I reflecting current editions of referenced standards.
• Revised definitions for combustible dust and grounding to align with terminology specific to NFPA 77.
• Updated characterization of low, medium, and high resistivity powders in Chapter 15 to reflect generally accepted international standards.

Stay current on static electricity hazard controls and grounding and bonding best practices with the 2019 edition of NFPA 77.
