Are You Ready for IFC Section 320? Lithium Battery Storage Rules Are Coming Fast

The Complete Guide to Lithium Battery Storage Compliance Under the 2024 International Fire Code

Lithium-ion battery storage in the United States is moving toward a more unified standard—but until adoption is complete, businesses face a patchwork of local and state rules. This variability creates challenges for facilities storing large battery inventories, especially as insurers, fire marshals, and local authorities apply different interpretations of safety requirements.

The 2024 International Fire Code (IFC), particularly Section 320, is emerging as the benchmark for lithium battery storage. It addresses storage configuration, fire suppression, hazard mitigation, and emergency planning. These measures are not mere paperwork—they are essential for minimizing fire risks, protecting employees, and safeguarding property.

Even in jurisdictions that have yet to adopt the 2024 IFC, aligning storage practices now has significant benefits. Doing so minimizes operational disruption when rules take effect, helps maintain insurance coverage, and positions a business as a proactive safety leader. Waiting until adoption is mandatory can result in costly retrofits, forced inventory relocation, or shutdowns.

In this article, we examine four aspects of lithium battery storage compliance: the growing influence of IFC Section 320, why early adoption is a competitive advantage, how to prepare for varying enforcement timelines, and strategies for integrating these standards into your facility design.

IFC Section 320: The Emerging National Standard for Battery Storage

IFC Section 320 provides the most comprehensive, up-to-date framework for storing lithium batteries in commercial and industrial settings. Its provisions cover key safety elements:

• Threshold quantities requiring operational permits
• Fire barriers and/or thermal performance packaging/containers
• Use of approved fire suppression systems
• Ventilation and explosion-proofing
• Smoke and radiant energy detection systems
  
  

Many states and municipalities are now moving toward adoption of the 2024 IFC. The International Code Council (ICC) notes that its fire codes are updated on a three-year cycle, with adoption typically occurring within 12–24 months. Early adopters—such as New Jersey and parts of California—are already enforcing elements of Section 320, particularly in high-density storage environments.

By understanding these requirements now, companies can avoid reactive compliance. Americase’s storage-ready containment solutions are designed to meet IFC criteria, giving operators a head start before these rules become universal.

Why Early Adoption Protects Operations and Reputation

Proactively aligning with Section 320—even before local adoption—offers operational and reputational advantages. Insurers increasingly expect facilities to meet IFC-level safety standards, regardless of jurisdiction. According to the National Fire Protection Association (NFPA), lithium-ion battery fires in storage settings have increased over 25% in the past five years, prompting underwriters to raise safety requirements.

Meeting these standards early can:

• Prevent insurance premium increases or coverage denials
• Reduce downtime by minimizing fire or incident risk
• Enhance credibility with regulatory authorities and customers
  
  

For example, a large distribution center in Illinois implemented IFC-aligned storage racks, suppression systems, and alarm systems before state adoption. When local fire inspectors arrived, they passed the facility without issue—saving both time and potential modification costs.

Preparing for Staggered State and Local Adoption

IFC adoption is not instantaneous nationwide. States and cities may take months—or even years—to enact updates. Some jurisdictions modify the code before adoption, adding another layer of complexity. The ICC maintains an adoption map showing which states have adopted each code edition and where changes have been made.

For companies with multi-state operations, staggered adoption can mean meeting multiple standards simultaneously. In storage, the solution is often to implement the highest standard across all facilities, ensuring compliance regardless of location.

Americase helps clients evaluate their current storage practices against Section 320 to identify gaps and prioritize upgrades, avoiding last-minute retrofits when the code becomes enforceable.

Integrating IFC Standards into Facility Design

The most cost-effective time to meet IFC Section 320 is during facility design or major renovation. Retrofitting storage layouts, installing new suppression systems, or reconfiguring hazard zones after construction is far more expensive.

Section 320’s requirements for fire barriers, ventilation, and fire suppression systems can be integrated into layout planning to reduce future compliance costs. Partnering with code-aware design teams and suppliers ensures that the facility remains compliant even as battery technology and fire safety research evolve.

Americase works with engineering teams to provide containment and packaging solutions that complement facility fire safety strategies—making compliance part of the operational foundation, not an afterthought.

Staying Ahead of the Storage Compliance Curve

Lithium battery storage regulations are converging toward the 2024 IFC, but full adoption will take time. The safest and most cost-effective path is to align with Section 320 now, regardless of local adoption status. Early action safeguards operations against fire risk, protects insurance coverage, and positions a company as a leader in safety compliance.

Americase continues to deliver innovative storage solutions that meet IFC Section 320 requirements and beyond—ensuring our clients are prepared not just for today’s rules, but for tomorrow’s.
