Chile Leads Lithium Supply but Lags on Battery Safety Rules

Chile sits at the centre of the global lithium supply chain, yet a seminar held today in Santiago concluded that the country’s regulatory framework for lithium battery safety has been overtaken by the speed of deployment across mining, electric mobility, and grid-scale storage. The University of Santiago (USACH) convened regulators, emergency services, academics, and private industry on 27 July 2026 under the explicit framing of detecting regulatory and safety gaps. The participation of agencies including SERNAGEOMIN, DIRECTEMAR, and the DGAC signals that institutional concern has moved beyond academic discussion. This article identifies which sectors face the highest immediate risk, what existing regulatory instruments do and do not cover, and what coordinated policy action is now being called for, giving investors, operators, and policy observers a clear map of where Chile’s lithium battery regulation currently stands and where it is headed.

Santiago seminar puts Chile’s lithium safety blind spot on the institutional agenda

The seminar, titled “Detection of Regulatory and Safety Gaps in the Use of Lithium Batteries,” was organised by the USACH Mining Engineering Department and held on 27 July 2026. It was characterised not as routine academic programming but as an initial step toward addressing a challenge expected to grow in importance over coming years.

The institutional breadth of the room told its own story. Speakers and attendees included:

• Francisco Hernández, USACH academic
• Amador Guzmán, Carnegie Mellon University
• Rodrigo López, president of the National Fire Prevention Association (ANAPCI)
• Pedro Ibarra, Standards Director, National Standardisation Institute (INN)
• Ricardo Buzzetti, First Lieutenant, Second Santiago Fire Company
• Hans Kauffmann, Head of the Laboratories Department, SERNAGEOMIN

Public agencies represented included SERNAGEOMIN, DIRECTEMAR, and the DGAC, spanning mine safety, maritime transport, and civil aviation. A roundtable titled “When Technology Advances Faster Than State Capacity” brought these institutional voices together in a single session.

Attendees agreed that continued dialogue among universities, private companies, government agencies, and emergency response teams is necessary to build technical capabilities and updated regulatory frameworks. For operators and investors, this seminar represents the first formal, multi-institutional acknowledgement that Chile’s lithium battery governance has a structural problem.

How lithium batteries are already regulated in Chile, and where the coverage stops

Chile is not starting from zero. Several regulatory instruments address specific phases of the battery lifecycle, but each covers only part of the problem.

The Superintendencia de Electricidad y Combustibles (SEC) issued Technical Instruction RGR N° 06/2020, which requires certification to IEC 62619 or UL 1973/UL 9540 for stationary battery energy storage systems (BESS), mandates battery management systems (BMS) for all lithium storage installations, and requires design-stage evaluation of fire-risk factors. This provides a baseline for stationary grid storage but does not extend to mobile or mining applications.

Consumer charger certification has been in force since 31 March 2024, covering devices up to 24 V DC and 50 VA. Dangerous goods transport is governed by IATA Dangerous Goods Regulations and UN 38.3 testing standards, with DGAC and DIRECTEMAR holding modal authority over air and maritime transport respectively.

Lithium cell transport approvals under IATA and UN 38.3 frameworks can take 18 months or more for novel chemistries, as the pathway for prototype cells operating under ICAO Special Provision A88 illustrates, underscoring why transport regulation is one of the more mature but still complex layers of the broader battery safety architecture.

End-of-life obligations are advancing while operational safety rules lag

The draft Extended Producer Responsibility (REP) decree covers lithium-ion batteries of 5 kg or more, including those embedded in vehicles or machinery. It sets progressive collection targets up to 50% for lithium-ion, requires free take-back by large retailers, mandates labelling and annual reporting, and places producer responsibility on importers. Phased obligations begin 18 months after entry into force.

The contrast is notable: waste-stream obligations are moving toward relative clarity while equivalent operational safety rules for the same batteries during their service life remain incomplete. Operators placing large lithium systems into service in Chile currently navigate obligations spread across at least four separate instruments with no single integrated compliance pathway.

What lithium battery safety regulation actually needs to cover

Lithium battery incidents differ categorically from conventional electrical or fuel hazards. Understanding why is essential to grasping why existing codes are insufficient.

Thermal runaway, the self-sustaining overheating of a lithium cell, can propagate across cells and modules once initiated. It is resistant to suppression and can re-ignite after apparent extinguishment, sometimes hours later. The key hazard characteristics include:

• Propagation: Heat from one failing cell can trigger adjacent cells, creating a cascading failure across modules
• Gas emission: Events produce toxic and flammable gases requiring specific respiratory protection and zoning
• Re-ignition: Batteries may appear extinguished and then reignite, complicating incident management
• Suppression complexity: Standard water application may be insufficient or may require careful control to avoid secondary effects

Peer-reviewed research on thermal runaway gas emissions documents that lithium-ion cells release a mixture of toxic and flammable gases during failure events, with composition and volume varying by chemistry and state of charge, findings that underpin why respiratory protection and exclusion zoning requirements need to be specified in dedicated regulatory instruments rather than inherited from generic electrical codes.

Existing norms need to adapt to new technological realities. — Ricardo Buzzetti, First Lieutenant, Second Santiago Fire Company, 27 July 2026

International reference standards such as NFPA 855 address compartmentalisation, detection, suppression, and incident management for large battery installations. Chile’s generic electrical codes were not designed to capture these chemistry-specific dynamics. The institutional concern raised at today’s seminar is technically grounded: general electrical safety codes are not an adequate substitute for lithium-specific regulation.

Mining and grid storage face the highest-stakes exposure

Underground mining: where diesel-era codes meet lithium-era equipment

As Chilean mining operations decarbonise, battery-electric haul trucks and underground equipment introduce high-capacity lithium systems into environments with compounding risk factors:

1. Confined underground spaces with limited ventilation
2. Constant exposure to vibration and mechanical stress
3. Proximity to explosives, fuels, and other hazardous materials
4. Safety codes written for diesel equipment and conventional electrical systems, not lithium-specific fire dynamics or gas emission hazards

SERNAGEOMIN’s presence at the seminar signals that the agency is beginning to engage with this gap. Existing mining safety codes do not yet systematically embed lithium battery failure modes, and the consequences of a thermal runaway event underground, where ventilation is constrained and evacuation options are limited, are categorically more severe than in open-air environments.

Grid-scale BESS in the northern solar belt

Northern Chile’s heavy solar penetration is driving BESS deployment to manage intermittency. Multi-container battery arrays introduce complex thermal runaway scenarios, including potential domino effects between modules and interactions with substation protection systems and nearby infrastructure.

SEC RGR N° 06/2020 provides a baseline, but it predates the current deployment scale and does not fully substitute for dedicated codes such as NFPA 855. Global experience has demonstrated that grid-scale lithium storage fires require specialised engineering and dedicated codes beyond generic electrical regulations. Mining and energy storage operators with Chilean assets face the greatest near-term exposure to both incident risk and reactive regulation.

Grid-scale BESS regulatory approvals in more developed frameworks, such as the AEMO and ElectraNet pathway required for Australia’s 140 MW Aurora project, illustrate the multi-agency technical review that Chile’s SEC RGR N° 06/2020 only partially replicates, particularly for large multi-container installations where module-to-module thermal runaway interactions require dedicated engineering assessment.

The NFPA 855 standard sets out requirements for compartmentalisation, detection, suppression, and incident management for stationary energy storage systems, providing the international benchmark against which Chile’s current codes are being measured and found wanting.

Emergency services lack standardised protocols for large battery incidents

Current transport regulations (IATA, UN 38.3) ensure that emergency information accompanies lithium battery shipments, but they cover logistics incidents only. For large stationary installations or on-site mining incidents, Chilean fire services currently rely on ad-hoc guidance, manufacturer information, or foreign standards.

Three categories of provision are missing:

• Mandatory emergency response plans tailored to lithium battery chemistry for sites hosting substantial installations
• Standardised training requirements for firefighters and first responders addressing thermal runaway, toxic gas releases, and re-ignition scenarios
• Equipment specifications for handling large battery fires and gas releases, including respiratory protection and zoning protocols

Existing norms need to adapt to new technological realities. — Ricardo Buzzetti, First Lieutenant, Second Santiago Fire Company

Buzzetti’s observation, made at today’s seminar, reflects a practical concern: incident outcomes at battery-intensive industrial sites depend significantly on local first-responder familiarity with lithium chemistry. That inconsistency represents both a safety liability and a potential regulatory trigger for stricter site-level planning obligations.

Cross-agency coordination is the missing piece investors and operators should watch

The seminar concluded that cross-institutional coordination linking SEC, SERNAGEOMIN, DGAC, DIRECTEMAR, INN, environmental regulators, and emergency services is essential. Four categories of future regulatory action were identified:

• Coordination frameworks linking the agencies that each hold a piece of the battery safety puzzle
• Dedicated technical standards for large lithium systems in mining and grid storage, harmonised with international codes such as NFPA 855
• Mandatory emergency planning requirements for sites hosting substantial lithium battery installations
• Incident reporting systems to systematically learn from near-misses and fires and update norms accordingly

What a tightening regulatory environment means for current operators

Today, a lithium battery used in a mining truck or BESS installation may simultaneously invoke SEC electrical rules for installation and certification, dangerous goods regulations for transport and import, and REP producer responsibility obligations at end-of-life. No single integrated instrument covers design through decommissioning.

The REP battery decree timeline and SEC’s expanding certification protocols indicate a clear direction toward stronger regulation, but the pace is uneven. A serious incident at a mining operation or grid infrastructure could trigger rapid, reactive regulatory measures, moratoria, or permit conditions. Investors and operators who map their exposure now against the likely direction of cross-agency reform will be better positioned to anticipate compliance requirements and avoid reactive capital expenditure.

Chile’s lithium governance gap is a structural challenge, not a temporary oversight

Chile’s centrality to the global lithium economy makes this regulatory gap a matter of international significance. The USACH seminar on 27 July 2026 represents the start of a process rather than the resolution of one, with institutional actors now formally acknowledging that technology deployment has outpaced state capacity.

Battery metals demand drivers, including AI data centre energy storage, EV adoption, and grid-scale renewables integration, are converging on the same constrained supply pipeline, which explains why Chile’s lithium governance gap carries weight well beyond its own borders.

Operators and investors with exposure to Chilean lithium, mining electrification, or grid storage should monitor three leading indicators of regulatory progress: the REP battery decree consultation process, SERNAGEOMIN engagement with mining electrification safety, and any cross-agency framework announcements from SEC and INN.

Lithium supply chain concentration in Chile has become more visible to capital markets as lithium carbonate prices recovered to US$27,911 per tonne in May 2026 and institutional investors re-rated producers with direct Chilean exposure, making governance and regulatory risk a more material consideration for equity pricing than it was during the prior downcycle.
