2027 NFPA 30 Second Draft Ballot Passes: Key Changes Ahead

The NFPA 30 Technical Committees of NFPA 30, Flammable and Combustible Liquids Code have officially passed the second draft ballot for the 2027 edition, marking a significant milestone in the evolution of flammable and combustible liquid safety standards. This achievement reflects extensive task group collaboration, led and supported by Jensen Hughes technical experts, to ensure the next edition addresses emerging challenges and provides practical solutions for industry stakeholders.

Several important changes are coming that users should prepare for:

1. Shift to Performance-Based Hazardous Area Classification

(Second Revision 494)

Perhaps the most substantial change is the move toward a performance-based method for hazardous area classification. The revision is intended to simplify the criteria used for classifying areas needing electrical equipment rated for hazardous locations, while also providing more explanations on how to use other available technical guidance and resources. This approach allows facilities to tailor protection strategies based on actual risk rather than prescriptive (and often overly conservative) rules, enabling right-sized solutions that balance safety and cost-effectiveness.

2. Introduction of Ignitable Liquid Drainage Floor Assemblies (ILDFA)

(Second Revisions 447, 452, 453, 455, 456)

A major addition to NFPA 30 is the availability of ILDFA as a new design option for liquid drainage and containment. These assemblies offer an innovative alternative to traditional drainage or sump systems, providing greater flexibility in design and installation – particularly for existing facilities where retrofitting of drainage and containment solutions can prove burdensome. ILDFAs can help streamline compliance while maintaining robust protection for storage and handling of ignitable liquid hazards. ILDFAs have increased complexity and operational considerations which should be factored into any analysis of whether to pursue this option.

3. Clarification of Explosion Control Triggers

(Second Revision 454)

The revised standard clarifies that explosion hazards may be present at both the equipment and room level. This change reduces ambiguity and ensures that facilities apply explosion protection consistently and effectively, mitigating risk and improving safety outcomes. The triggers for explosion control require more careful consideration of the operating parameters of flammable liquid operations and systems, increasing opportunities for prevention schemes and right-sizing of an often misunderstood protection system.

4. Alignment of Pre-Incident Plans with NFPA 1660

(Second Revision 482)

Emergency action planning requirements are now aligned with NFPA 1660, the Standard for Emergency, Continuity and Crisis Management. This alignment promotes a more integrated approach to preparedness, ensuring that facilities storing and handling flammable and combustible liquids have plans that meet current best practices for emergency response and consider available emergency responder resources.

What This Means for You

These changes provide new opportunities for flexibility and optimization in facility and equipment protection, both for existing and new operations’ storage and handling of ignitable liquids. Jensen Hughes technical leaders are ready to support implementation, from evaluating ILDFA options to developing performance-based electrical classification strategies and updating emergency plans.
