Fire Safety in Lithium Ion Battery Facilities (2026 Risk Guide)
Lithium-ion batteries are easy to ignore until something goes wrong. They sit inside forklifts, backup systems, energy storage units, and charging stations, quietly doing their job. Most of the time, nothing happens. That is what makes the risk easy to overlook. When a failure does happen, it does not behave like a typical fire. Lithium ion battery fire safety has become a growing concern for facilities because these fires escalate quickly. They generate intense heat, release toxic gases, and are difficult to control once thermal runaway begins. A small issue during storage or charging can turn into a serious incident within minutes.
Many of these environments already deal with complex safety challenges, and lithium-ion systems add another layer to the overall fire risk in energy storage facilities. The scale adds pressure. The global lithium ion battery market is expected to exceed $182 billion by 2030. More batteries in use means more responsibility for managing safety correctly. For facilities handling these systems, prevention is not optional. It is part of daily operations.
What Is a Lithium Ion Battery and How Does It Work?
A lithium ion battery is a rechargeable energy system used across devices, vehicles, and industrial equipment. In facility environments, it powers everything from material handling systems to backup energy units. Understanding this system is important for improving lithium ion battery fire safety in high-risk environments. At its core, the battery works through the movement of lithium ions inside the cell. During charging, energy is stored as ions shift in one direction. When the battery is used, those ions move back, releasing power.
This process depends on a few internal parts working in balance. The anode stores ions, the cathode receives them, the electrolyte allows movement, and the separator keeps everything from short-circuiting. When this balance holds, the system operates safely. The problem starts when that balance is disturbed.
Heat, damage, or improper charging can push the battery into unstable conditions. This is where lithium ion battery safety becomes critical, especially in high-volume environments. Understanding how these batteries function is not just technical knowledge. It is also part of maintaining lithium ion battery fire safety in real-world facility conditions.
What Causes Lithium Ion Batteries to Catch Fire?
Lithium ion battery fires usually don’t start out of nowhere. In most cases, there’s a build-up of stress inside the cell before anything visible happens. The core issue is heat. When a battery starts generating more heat than it can release, things can get unstable very quickly. This is what people refer to as thermal runaway in lithium ion batteries, where the reaction continues to build once it starts. Once it begins, the temperature keeps rising, and the reaction feeds itself.
Part of the risk comes from how these batteries are built. They store a lot of energy in a small space. That’s what makes them useful, but it also means a failure can escalate faster than expected. This is where lithium ion battery fire safety becomes important, especially in facilities handling large volumes of batteries. In real environments, a few conditions show up again and again:
Physical Damage
A battery that gets dropped, crushed, or punctured can develop an internal short. Even a small impact can be enough to trigger it later.
Overcharging or Unstable Power Input
Charging beyond safe limits or using the wrong setup can push the battery past its tolerance. This often happens during charging ion lithium battery processes in busy facilities.
Heat Exposure Over Time
Poor airflow or placing batteries near heat sources increases internal stress. It may not fail immediately, but the risk builds.
Cell Defects or Aging
Not every failure is visible from the outside. Some cells degrade internally or have hidden defects that show up under load. Once a failure starts, it moves fast. Heat, gas, and pressure build together, and controlling the situation becomes much harder. That’s why lithium ion battery fire safety is less about reacting to fires and more about catching these conditions early.
Common Mistakes That Increase Lithium Ion Battery Fire Risks
Most lithium ion battery fire safety incidents are not caused by complex failures. They come from small, repeated mistakes that seem harmless at first. In busy facilities, these issues are easy to miss until something goes wrong.
Using the Wrong Charging Setup
Not all chargers behave the same. In many cases, incompatible or low-quality chargers are used just to keep operations moving. Over time, this creates stress inside the battery.
Leaving Batteries Charging Without Supervision
Charging often continues after work hours or during shifts when no one is monitoring. If a problem starts, it is usually noticed late.
Poor Airflow During Charging
Heat needs somewhere to go. Charging batteries in tight spaces or stacking them close together traps that heat and increases the risk.
Ignoring Early Warning Signs
Swelling, unusual warmth, or a strange smell are often dismissed as minor issues. In reality, these are early indicators of internal failure.
Continuing to Use Damaged Batteries
A battery that still works is often kept in use, even after being dropped or stressed. Internal damage does not always show immediately.
Improper Storage Conditions
Storing batteries in hot areas or without spacing adds continuous stress. The impact builds over time rather than all at once.
Loose Handling and Contact with Metal Objects
In some cases, batteries are stored with tools or metal parts. This increases the chance of accidental short circuits.
Incorrect Disposal Practices
Disposing of lithium-ion batteries with general waste creates risk during transport and handling, especially in large facilities.
Most of these issues are preventable, but only if they are taken seriously in daily operations. Lithium ion battery safety is not about one-time checks. It depends on how consistently these small details are managed.
Storage and Charging Safety Guidelines for Lithium Ion Batteries
Most lithium ion battery fire safety issues do not start during failure. They start much earlier, in how batteries are stored and charged day to day.
In facilities, this is where risk either builds quietly or stays under control. Paying attention to these conditions is a core part of maintaining lithium ion battery fire safety over time.
Storage Guidelines
Keep the Temperature Stable
Batteries should be stored in a cool, controlled environment. Around 15°C to 25°C works well. Heat speeds up chemical stress, while very low temperatures can damage the internal structure.
Store at Partial Charge, Not Full
Keeping batteries around 30 to 50 percent charge reduces internal pressure. Fully charged batteries are more sensitive to stress during storage.
Allow Space Between Units
Stacking batteries too closely increases the chance of heat transfer. Proper spacing helps prevent one failing unit from affecting others.
Use Fire-resistant Storage Areas
Dedicated cabinets or enclosures can slow down fire spread and improve containment if something goes wrong.
Separate Damaged Batteries Immediately
Any battery showing signs of swelling, cracks, or unusual behavior should be isolated. Keeping it with other units increases risk.
Keep Away From Flammable Materials
Storage areas should be clear of combustible items and direct heat sources.
Charging Guidelines
Charge in Well-ventilated Areas
Batteries can release heat and gases during charging. Without airflow, that heat builds quickly.
Use Correct Chargers and Systems
Charging equipment should match battery specifications. Mismatched setups are a common cause of overheating during charging ion lithium battery operations.
Avoid Charging in Bulk Without Monitoring
Large-scale charging setups need supervision. Problems often start in one unit and spread if unnoticed.
Do Not Charge Damaged or Unstable Batteries
Charging a compromised battery increases the chance of immediate failure.
Monitor Temperature During Charging Cycles
Sudden heat changes are often the first sign of internal issues. These practices may seem basic, but they play a major role in lithium ion battery safety. In most cases, preventing a fire is less about complex systems and more about maintaining lithium ion battery fire safety through consistent daily control.
Lithium Ion Battery Fire Safety Standards and Regulations
Most facilities don’t think much about standards until something goes wrong or an audit comes up. But when lithium-ion batteries are involved, these guidelines matter earlier than that.
They are not just rules on paper. They exist because the same mistakes have already caused fires in real environments. In practice, a few frameworks show up more often than others.
NFPA Guidelines
These focus on fire risk inside facilities. One of the main ideas is simple. If one battery fails, it should not take others with it. That is why spacing and separation matter.
OSHA Requirements
These are more about people than batteries. Safe handling, proper charging practices, and clear procedures during incidents all fall under this.
IEC and UL Standards
These relate to how batteries and systems are designed and tested before they even reach a facility.
Instead of listing rules, it helps to look at what they are trying to prevent. This is where lithium ion battery fire safety becomes part of everyday operations, not just compliance.
Most lithium ion battery fire safety standards focus on:
- Keeping temperature under control
- Avoiding heat and gas buildup
- Limiting how far a failure can spread
- Identifying damaged units early
You’ll notice something here. These are the same areas where most real-world incidents begin.
The difference is consistency. Facilities that treat these standards as daily practice usually avoid major issues. The ones that treat them as checklist items often deal with problems later.
Conclusion
Lithium ion battery fires rarely come down to one mistake. In most cases, it is a series of small decisions that build risk over time. A battery stored in the wrong place, a charging setup that is left unattended, or a warning sign that gets ignored. None of these seems urgent on its own, but they add up.
That is where most incidents begin. Lithium ion battery fire safety is not about adding more systems or complex controls. It comes down to how consistently basic practices are followed inside the facility.
Teams that pay attention to storage conditions, charging behavior, and early signs of failure usually catch problems before they escalate. The difference is not knowledge. It is discipline. When those everyday practices are taken seriously, the risk becomes much easier to manage, especially when aligned with proven battery fire prevention best practices.
FAQs
Are lithium ion battery fires dangerous?
Yes. Lithium ion battery fires burn at very high temperatures, release toxic gases such as hydrogen fluoride, and can reignite after appearing controlled. That makes them more difficult and hazardous than typical fires.
What is thermal runaway in lithium ion batteries?
It’s when the heat inside the battery starts increasing on its own and doesn’t stop. Once that cycle begins, temperature, gas, and pressure build together. At that point, the battery can fail very quickly.
How do you extinguish a lithium ion battery fire?
There isn’t a simple one-step method. In many cases, the focus is on cooling the battery and stopping the spread rather than fully “putting it out” immediately. That’s why trained response and proper setup matter.
Are there regulations for lithium ion battery safety in facilities?
Yes, and most facilities follow them more closely after an incident or audit. Standards from groups like NFPA or OSHA focus on storage, charging, and handling. They’re meant to reduce risk before it turns into a real problem.

Automating fire-rated doors requires robust evidence says ADSA
Technical testing for fire-rated doors
The Automatic Door Suppliers Association (ADSA) has established a cross-industry steering group to investigate the safety implications of automating existing fire-resisting timber doors.
This collaborative initiative aims to determine whether retrofitting hardware or routing cables for automation compromises the integrity of a fire-rated door system.
Industry leaders Record UK, dormakaba and GEZE UK are participating in the group alongside the Guild of Architectural Ironmongers and the British Woodworking Federation.
A fire test house will conduct controlled testing to replicate common installation scenarios such as drilling for cabling and replacing manual closing devices.
Findings from the research will establish an evidence base for the industry regarding how typical modifications influence fire performance.
Darren Hyde, Technical and Training Manager at ADSA, said: “Many of the questions we receive now relate to automating existing fire doors.
“When you retrofit automation, you’re potentially changing the construction of the door.
“What we want to do as an industry is understand exactly how those modifications affect fire performance.”
Guidance for engineers and specifiers
Technical data from the programme will be used to create new guidance for building owners and fire safety professionals scheduled for release later this year.
The document will provide practical methods for cable routing and fire-stopping to help engineers maintain door integrity during automation projects.
ADSA noted that while new-build projects use fully tested door systems, the retrofit environment is often less predictable for installers.
Hyde added: “In new-build, manufacturers can provide clear test evidence for complete systems.
“In retrofit situations, that level of certainty doesn’t always exist.
“We want to close that gap in understanding.”
The project intends to balance the accessibility benefits of automated movement with the necessity of maintaining established fire safety standards.
ADSA expects the results to support more informed decision-making by demonstrating how existing doors can be adapted safely without requiring full replacement.
HMICFRS issues accelerated cause of concern for Northumberland Fire and Rescue Service
HMICFRS findings on site-specific risk information
Northumberland Fire and Rescue Service has been issued an accelerated cause of concern after an inspection identified failures in the management of risk information for high-risk premises.
His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) found that site-specific risk information (SSRI) used by the service was frequently inaccurate or out of date.
SSRI consists of detailed data used to inform firefighting tactics and protect the public during emergency incidents.
The inspectorate concluded that the service failed to provide operational personnel with the necessary support to gather this information effectively.
Accelerated causes of concern are reserved for instances where a fire service’s performance raises direct concerns regarding public safety.
Improvements required to address the HMICFRS cause of concern
The inspectorate recommended that the service must identify every location requiring a specific risk visit and ensure data is uploaded without delay.
Effective training must be provided to the workforce to ensure staff can identify SSRI requirements and understand the associated processes.
Personnel are required to inspect high-risk locations to ensure they are familiar with specific site hazards.
The service must implement quality assurance and strategic oversight to monitor the accuracy of the risk records.
Michelle Skeer, His Majesty’s Chief Inspector of Fire and Rescue Services, said: “I have issued an accelerated cause of concern as Northumberland Fire and Rescue Service doesn’t effectively manage risk information for high-risk premises.
“This is vital for helping protect firefighters and the public during an emergency.
“During our inspection, we found out of date risk information, cases where risks that been graded inaccurately and several sites with potential risks where no site-specific risk information was available.
“The service had identified 478 sites as requiring a SSRI record, but its quality assurance panel had only reviewed 37 of these sites.
“This means the service can’t know if its risk information is accurate and I am not confident the service has identified all places of risk.
“Northumberland Fire and Rescue Service must act urgently to identify all sites requiring a risk visit, make sure information is accurate and kept up to date and give staff the training they need to do this effectively.
“I will be closely monitoring its progress.”
The inspectorate found that some risk information currently held by the service was not effective for operational use.
Skeer noted that many sites with potential hazards had no site-specific information available at all.
New safety protocols announced following fatal Wang Fuk Court fire inquiry
Fire safety coordination mechanism launched following public inquiry
TThe Hong Kong Fire Services Department (FSD) will introduce a new system this month to manage building safety complaints following a public inquiry into the fatal Wang Fuk Court blaze.
The South China Morning Post scmp.com/news/hong-kong/society/article/3351019/confusion-over-government-agencies-roles-fire-oversight-tai-po-probe-revealsthat this mechanism aims to eliminate confusion regarding departmental jurisdictions by ensuring cases are referred to the most appropriate government unit.
This action follows an investigation into a 43-hour inferno at the Tai Po residential complex that killed 168 people and displaced nearly 5,000 residents on 26 November last year.
Michael Yung Kam-hung, an assistant director of the Fire Services Department, told an independent committee that his department lacked the construction expertise to handle complaints about flammable building materials.
Yung said: “We do not know how it would affect the project’s progress if we arbitrarily decide that certain materials cannot be used.”
The witness stated that legal action was not taken during the renovation of the estate because the department could not identify which materials were integral to the project.
Regulatory gaps identified during Wang Fuk Court fire investigation
The committee legal team noted that the disaster involved several human factors including the use of polyfoam boards to seal windows and substandard scaffolding mesh.
Lead counsel Victor Dawes SC argued that a serious regulatory vacuum existed because multiple agencies denied responsibility for supervising temporary structures and flammable materials used during renovations.
While fire officials claimed such items fell outside their remit, the Housing Bureau’s Independent Checking Unit (ICU) also stated it was not responsible for the temporary arrangements.
The FSD confirmed that future referrals contested by other departments will be escalated to senior management for cross-departmental coordination to prevent complaints from being ignored.
Yung accepted that the previous lack of clarity was not ideal and confirmed that the department would no longer expect residents to identify which authority should receive their reports.
Regarding the maintenance of fire water tanks at the site, senior station officer Ng Wing-kwong said internal guidelines did not require officers to verify the severity of reported leaks.
He noted that he could not provide an explanation for why officers were not required to double-check defects before allowing the continued shutdown of fire hosepipes.
Data centre expansion increases reliance on PFAS based fire suppressants
Data centre fire suppression systems use PFAS chemicals
Modern data centres increasingly rely on perfluoroalkyl and polyfluoroalkyl substances (PFAS) to manage high heat levels and mitigate fire risks associated with 24/7 server operations.
The Environmental and Energy Study Institute (EESI) reported that these synthetic chemicals are integral to clean agent fire suppression systems such as FM-200 and Novec 1230.
Unlike water-based alternatives, these agents are non-conductive and leave no residue – properties that prevent damage to sensitive electrical equipment and servers.
The durability of the carbon-fluorine bonds in these materials makes them resistant to environmental breakdown.
This persistence has led to the nickname forever chemicals because they accumulate in human tissue and ecosystems over time.
Toxic effects on the liver, blood, and kidneys are associated with bioaccumulation of these substances.
Market shifts and the phase out of Novec 1230
Fire safety procurement may face changes as major manufacturers move away from producing certain clean agents used in data centre environments.
The manufacturing conglomerate 3M confirmed it ended all PFAS manufacturing after previously announcing a deadline of late 2025.
This decision includes the cessation of Novec 1230 production.
Analysis of fire outbreaks in these facilities since 2021 indicates that risks often stem from equipment failures and lithium-ion battery failures in semiconductors.
Matt Dunn, a PFAS scientist at Tetra Tech, stated: “PFAS regulation represents a unique struggle due to how widespread the chemicals are.
“Since PFAS are in everyday products that are used by every American, from food to bath products, the question becomes: where do you draw the line?”
“Do you go after the user, or do you go after the manufacturer,” Dunn asks.
“And understanding the difference there is very important.”
Regulatory frameworks and legislative proposals
Federal and state authorities are evaluating different methods to manage the presence of these chemicals in industrial infrastructure.
Maine and Minnesota have introduced legislation to restrict products containing intentionally-added chemicals, though some fire safety applications remain exempt.
The 119th Congress proposed the Clean Water Standards for PFAS Act of 2025 (H.R.6668) to establish emission limitations under the Clean Water Act.
The PFAS Research and Development Reauthorization Act of 2025 (H.R.6667) seeks to extend funding for research into these substances.
A 2025 executive order directed several federal departments to expedite permitting processes for data centre infrastructure.
These fast-track initiatives cover the materials required for coolants, semiconductors, and fire suppressants.

The data drive: How UL Solutions supports business continuity through certification
Simon Ince, Program Manager, UL Solutions, explores fire safety considerations in data centres and potential strategies
The global data centre industry is constantly pushing the boundaries of innovation in power distribution, cooling, energy storage and server technology.
While these advances bring exciting opportunities, they also introduce new risks.
Mitigating many of these fire risks can be supported by choosing certified fire protection systems that have been properly specified, installed and maintained.
A global industry
While the data centre industry is expanding worldwide, data centres must still comply with regional fire protection standards.
Building codes and regulations differ from country to country, but they generally include prescriptive and performance-based fire safety requirements designed to provide a reasonable level of life safety and some property protection.
However, these regulations often lack measures specifically geared toward maintaining business continuity.
These model codes typically consider the size and complexity of a building, occupancy levels, fire load and potential fire growth rates, and require both passive and active fire protection to achieve an acceptable level of risk to life and structural property.
Regional differences in codes and approvals mean that the methods for achieving regulatory fire protection vary.
Therefore, wherever a data centre business operates, facilities must comply with all applicable local fire safety regulations.
Organisations such as UL Solutions support compliance with regional building codes and installation standards by providing third-party testing, inspection and certification designed to complement region-specific safety requirements.
Business continuity
Data centres operate 24 hours a day, 365 days a year.
For this sector, effective fire protection strategies must also be designed to consider business continuity.
Even a relatively small fire can result in significant operational disruption and financial loss.
Industry data indicates that fire disruption accounts for approximately 14% of significant outages.
While the total number of fire-related incidents may be decreasing, global reliance on digital infrastructure continues to grow.
As a result, outages are becoming more impactful and costly.
The average cost of downtime can soar as high as $9,000 per minute, with large enterprises facing average costs of $540,000 per hour.
Although major data centre fires are infrequent, their consequences can be severe.
In September 2025, a lithium-ion battery fire in South Korea forced the closure of a government-run data centre, disrupting 647 public systems.
Critical services were temporarily paralyzed, with the incident highlighting the vulnerability of critical digital infrastructure to fire-related events.
At the same time, the pace of digital transformation and artificial intelligence (AI) development is accelerating.
Global data centre construction is projected to grow by approximately 11.10% annually through 2034.
This rapid expansion is driving innovation in design, construction methods and energy systems.
As a testing, inspection and certification provider, UL Solutions works with major data centre providers to support innovation by evaluating safety performance.
Regulations often struggle to keep pace with emerging technologies.
When new risks arise, science-based testing and certification protocols help demonstrate conformity with existing regulations and advance safety where standards have yet to be established.
One example is UL 2755, the Outline of Investigation for Prefabricated Modular Data Center Systems and Related Modular Units, which addresses the increasing demand for prefabricated modular data centres (MDCs).
Modular construction allows faster deployment than conventional builds, with modules often manufactured in one country and installed in another.
Supporting code compliance during factory construction is therefore essential.
Start with a fire strategy
Early engagement with a competent local fire engineer is essential during the planning phase of a data centre project.
Fire engineers routinely develop life safety strategies based on a site-specific hazard mitigation analysis (HMA), but they can also incorporate resilience and business continuity measures into such strategies.
Maintaining fire engineering involvement throughout construction helps ensure that the “on paper” strategy is properly implemented.
For example, many data centres rely on battery energy storage systems (BESS) to provide reliable and continuous power.
These systems can provide immediate backup power until standby generators start.
Fire engineers rely on design guidance such as NFPA 855, which addresses the installation of stationary energy storage systems and requires certification to UL 9540, the Standard for Energy Storage Systems and Equipment.
UL 9540A, the Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems, is used to evaluate fire propagation characteristics of specific BESS.
Understanding how a battery system behaves under fire conditions is essential to managing that risk.
Design with function in mind
In addition to fire engineers, specialist designers for active fire protection, such as detection and suppression, along with passive fire protection for fire containment, should be involved early in the planning process.
For example, within the Royal Institute of British Architects (RIBA) Plan of Work, Technical Design is traditionally completed at Stage 4.
However, introducing detailed fire protection considerations during Stage 2 (Concept Design) can help identify and resolve potential fire protection issues early in construction.
Data centres contain extensive building services, such as power cables and air conditioning duct work, that penetrate fire-resisting compartments.
How these services pass through fire-separating elements while still maintaining fire separation is crucial.
Specialist designers understand the importance of third-party certification and selecting systems with verified performance.
Tools such as Product iQ® allow designers to confirm the tested scope and application of products.
Matching certification data to real-world installation conditions helps prevent costly remedial work later.
Protect, detect and suppress
Active and passive fire protection systems must perform reliably when required.
Selection should be based on verified performance testing, as failure during a fire event could result in significant and costly downtime.
Structural fire resistance and compartmentation are fundamental to any onsite fire protection strategy.
Standards such as UL 263, the Standard for Fire Tests of Building Construction and Materials(also recognized as ASTM E119), support the evaluation of structural stability and fire separation.
Separating plant rooms from server halls, for example, limits fire spread and protects critical assets.
Early fire detection is equally important.
Data centres typically have high airflow due to cooling requirements, making traditional detection less effective.
Aspirating smoke detection systems, which continuously sample air near server racks, provide very early warning.
UL 268, the Standard for Smoke Detectors for Fire Alarm Systems, specifies performance requirements for these detection systems.
Fire suppression systems vary depending on the area and risk profile within the data centre.
Typically, inert gas systems and water mist systems are used in areas containing sensitive electrical equipment.
Regardless of the type of system chosen, the components and system should have been tested and certified to be suitable for the specific on-site risk scenario they are intended to mitigate.
Competence matters
Specifying tested and certified products is only part of the solution.
Improper installation can undermine even the best-designed systems.
Installer competence should be established before work commences to avoid costly and disruptive remediation.
Schemes such as the UL Solutions Qualified Fire Stopping Contractor Program can support due diligence in selecting competent specialist contractors.
In a sector where uptime is paramount, fire protection must be approached holistically.
From building design and fire strategy through product selection and installation, each stage must be synchronised to protect life and to support business continuity.
Therefore, the competence of all involved must be specified and vetted.
As digital infrastructure continues to expand, competent specialists equipped with third-party verified fire safety solutions can help drive safer, more reliable data centre operations.
Ongoing management, testing and maintenance
Getting the design, specification and installation of fire protection systems right, helps reduce the risk of downtime from day one.
However, without ongoing inspection, testing and maintenance of fire safety systems, even the best systems may not function as intended over time.
Many data centre providers implement externally audited business continuity management systems, such as ISO 22301 or rely on data centre–specific guidelines such as UL 3223, the Outline of Investigation for Data Center Certification.
Documented, audited processes for fire risk mitigation can provide a proactive approach to maintaining the fire protection system in a data centre.
