NFPA 30, Flammable and Combustible Liquids Code 2021

Help improve fire safety, reduce operational risks, and support compliance when working with ignitible liquids using NFPA 30, Flammable and Combustible Liquids Code.

NFPA 30 provides comprehensive requirements for safeguarding facilities, personnel, and operations against fire, explosion, and environmental contamination hazards associated with the storage, dispensing, handling, transfer, and use of ignitible liquids. Widely adopted and enforceable under many state fire prevention and building codes, the code is essential for organizations operating in manufacturing, chemical processing, oil and gas, warehousing, and related industries.

The code covers indoor and outdoor liquid storage containers and tanks, hazardous material storage lockers, tank vehicles, piping systems, electrical systems, processing facilities, storage areas, and wharves, helping organizations maintain safer operations and regulatory compliance.

Who Uses NFPA 30?

NFPA 30 is valuable for professionals responsible for flammable and combustible liquid safety and compliance, including:

• Facility managers
• Fire protection engineers
• Safety and compliance professionals
• Contractors and installers
• Inspectors
• Authorities having jurisdiction (AHJs)
• Industrial operations personnel

These professionals rely on NFPA 30 to help:

• Apply requirements for the safe storage, handling, and use of ignitible liquids
• Correctly classify hazardous materials and liquid hazards
• Manage fire and explosion prevention strategies
• Oversee fire protection system requirements and risk control measures

Highlights

Revisions and additions to the code reflect evolving industry practices and advancements in technology, including:

• Major revisions to the liquid classification system, introducing the term ignitible liquid and transitioning away from the traditional use of flammable liquid and combustible liquid
• A new classification approach based exclusively on physical properties such as flash point and boiling point
• Improved consistency across overlapping regulatory systems used by fire officials, occupational safety authorities, and transportation agencies
• Introduction of the term ignitible liquid to encompass all liquids with a measurable flash point
• Retention of the terms flammable liquid and combustible liquid in a limited capacity to assist users during the transition
• Reorganization of Chapter 4 to establish the new liquid classification scheme based on flash point and boiling point criteria
• Revisions to Chapters 1, 3, and 4 to improve consistency in terminology, scope, and liquid classification procedures
• Implementation of the updated classification system throughout the code and annexes
