Full title and description

NFPA 30: Flammable and Combustible Liquids Code — 2021 edition. This code provides minimum requirements for the safe storage, handling, and use of ignitible (flammable and combustible) liquids in containers, portable tanks, tanks, and in associated piping and systems, and establishes fire-protection, emergency-planning, and operational controls to reduce fire and explosion risk.

Abstract

NFPA 30:2021 consolidates requirements and guidance for classifying liquids by flash point and boiling point, for determining maximum allowable quantities and control-area limits, and for specifying fire protection, electrical classification, grounding/bonding, storage, transfer, and dispensing practices. The 2021 edition introduced a revised classification approach emphasizing the term "ignitible liquid" and updated provisions across chapters to align scope, terminology, and application of protective measures.

Scope

Applies to the storage, handling, and use of ignitible liquids (including waste liquids) in industrial, commercial, and institutional occupancies. The code covers classification of liquids, design and layout of storage areas, container and tank requirements, piping and transfer systems, electrical and ignition-source control, fire-protection system requirements, emergency planning, inspection and maintenance, and administrative controls such as permits and enforcement.

Key topics and requirements

• Introduction of the term "ignitible liquid" and a liquid-class system based on flash point and boiling point.
• Classification criteria and test-method references for determining flash point and boiling point.
• Requirements for storage in containers, portable tanks, IBCs, and bulk storage tanks including siting, secondary containment, and ventilation.
• Maximum allowable quantities (MAQs) and control-area definitions and limits for different occupancies.
• Electrical area classification, bonding and grounding requirements to control static and other ignition sources.
• Fire-protection and suppression system requirements (sprinklers, foam systems, hydrants) tailored to liquid class and storage arrangement.
• Requirements for piping, unloading/loading operations, transfer procedures, and overfill/pressure-relief provisions.
• Operational controls: permits, signage, security, inspection, maintenance, and emergency planning/training.
• Annex material providing explanatory material, sample ordinances, and calculation guidance (informational annexes).

Typical use and users

Used by fire protection engineers, facility safety managers, chemical/petroleum industry operators, storage-tank designers, code officials, authorities having jurisdiction (AHJs), insurance representatives, contractors, and emergency responders for design, review, permitting, and inspection of facilities that store, handle, or use ignitible liquids.

Related standards

Commonly referenced and cross-referenced standards include NFPA 30A (motor fuel dispensing), NFPA 30B (aerosol products), NFPA 58 (LPG), NFPA 70 (NEC), NFPA 13 (sprinkler systems), NFPA 1 (Fire Code), NFPA 101 (Life Safety Code), and other NFPA standards addressing storage, tank vehicles, and hazardous materials handling.

FAQ

Q: What is this standard?

A: NFPA 30:2021 is the National Fire Protection Association's code that establishes requirements for the safe storage, handling, and use of ignitible (flammable and combustible) liquids.

Q: What does it cover?

A: It covers classification of liquids by flash point/boiling point, container and tank storage, piping and transfer operations, maximum allowable quantities and control areas, fire-protection and suppression requirements, electrical and ignition-source controls, emergency planning, inspection, maintenance, and administrative controls.

Q: Who typically uses it?

A: Fire protection engineers, facility and safety managers, code officials/AHJs, designers, contractors, insurers, and emergency responders use the code for design, permitting, compliance, and inspection activities involving ignitible liquids.

Q: Is it current or superseded?

A: The 2021 edition was the active NFPA 30 edition following its issuance in 2020, but it has been superseded by a later edition (the 2024 edition). Users should confirm which edition and any applicable TIAs/errata are enforced by their authority having jurisdiction.

Q: Is it part of a series?

A: Yes. NFPA 30 is part of a family of NFPA documents addressing liquid fuels and hazardous liquids, including NFPA 30A and NFPA 30B, and it cross-references many other NFPA standards relating to fire protection, electrical installations, and hazardous materials.
