Lithium-ion battery storage in Ireland is not governed by one standalone workplace regulation. Depending on the application, duties can arise under the Safety, Health and Welfare at Work Act 2005, General Application Regulations, Fire Services Acts, EU Batteries Regulation and waste legislation. Stationary BESS also has specific EU product-safety requirements, while waste lithium-ion batteries are covered by dedicated EPA guidance.
No. Ireland does not currently have one regulation establishing a universal design or storage specification for every workplace that stores or charges lithium-ion batteries.
Instead, the legal and safety requirements depend on matters including:
A small workplace charging power-tool batteries therefore presents a different risk profile from an industrial battery warehouse, EV battery operation or grid-scale Battery Energy Storage System.
The Safety, Health and Welfare at Work Act 2005 establishes the general occupational safety framework applying to workplaces in Ireland.
Under Section 19, employers must identify workplace hazards, assess the risks they present and maintain a written risk assessment.
For lithium-ion battery activities, the assessment may need to consider:
The risk assessment must be reviewed where there has been a significant change or where there is reason to believe it is no longer valid.
Section 11 of the Safety, Health and Welfare at Work Act 2005 requires employers to prepare and revise adequate plans and procedures for emergencies and serious and imminent danger.
The measures must be appropriate to the workplace and include provision for:
For workplaces handling significant lithium-ion battery inventories, emergency planning should take account of foreseeable battery incidents and the particular characteristics of the batteries present.
Fire safety in Irish workplaces is also governed by the Fire Services Acts 1981 and 2003.
Section 18 places duties on persons having control over premises to:
The Department of Housing’s Fire Safety Guide for Building Owners and Operators applies these duties broadly to premises other than a dwelling house occupied as a single dwelling.
Lithium-ion battery storage should therefore form part of the wider fire-safety management arrangements for the premises.
The Health and Safety Authority states that workplace fire risk should be assessed as part of the employer’s written risk assessment under Section 19 of the Safety, Health and Welfare at Work Act 2005.
The assessment should address:
For a workplace storing or charging lithium-ion batteries, those arrangements should reflect the battery inventory and foreseeable failure scenarios rather than treating the batteries as ordinary combustible stock.
Yes, different parts of the Safety, Health and Welfare at Work (General Application) Regulations 2007 can be relevant depending on the battery installation and workplace activities.
In particular, the Regulations contain requirements concerning electrical installations and electrical equipment.
Electrical equipment must be constructed, installed, maintained, protected and used so as to prevent danger.
Battery charging installations may therefore require consideration of:
The appropriate electrical controls should be determined by competent persons for the installation involved.
Potentially. Part 8 of the Safety, Health and Welfare at Work (General Application) Regulations 2007 addresses explosive atmospheres.
A lithium-ion battery failure can release gases, some of which may be flammable. Whether this creates an explosive-atmosphere risk requiring controls under Part 8 depends on the circumstances of the installation and potential release.
Where an explosive atmosphere may arise in quantities capable of endangering people, the employer may need to consider:
The presence of lithium-ion batteries does not automatically make a battery room or battery store an ATEX zone. The classification must follow from the actual risk assessment and foreseeable release conditions.
See our ATEX Ireland guide for further information.
Thermal runaway is an uncontrolled self-heating process that can occur when a lithium-ion cell becomes unstable.
Potential initiating events include:
As the cell heats, internal reactions can generate further heat and gas. In severe cases this can lead to venting, fire, rupture or explosion.
Heat from one failing cell can also affect adjacent cells, allowing an incident to propagate through a battery module, pack or larger battery inventory.
A battery-storage risk assessment should reflect the batteries and activities actually present at the site rather than relying on one generic rule.
Relevant factors can include:
Yes. Charging introduces additional electrical and thermal risks that may not be present to the same extent during passive storage.
A charging assessment may need to consider:
Charging equipment and procedures should follow the battery and charger manufacturers’ instructions and the findings of the workplace risk assessment.
Damaged, swollen, overheating, leaking or otherwise abnormal batteries should not simply be returned to ordinary battery stock.
The organisation should have procedures for identifying and isolating suspect batteries.
Depending on the circumstances, controls may include:
Damaged batteries can also be subject to specific dangerous-goods transport requirements when they are moved off site.
Regulation (EU) 2023/1542 concerning batteries and waste batteries is directly applicable across the European Union, including Ireland.
The Regulation applies throughout the battery lifecycle and contains requirements covering areas including:
It applies to several categories of batteries, including industrial batteries, electric-vehicle batteries, portable batteries and batteries for light means of transport.
The Regulation applies in stages, with different obligations taking effect on different dates.
Yes. Article 12 of Regulation (EU) 2023/1542 contains specific safety requirements for stationary battery energy storage systems.
A stationary battery energy storage system placed on the market or put into service must be safe during normal operation and use.
The Regulation also requires technical documentation addressing relevant safety hazards and evidence of appropriate testing against the safety parameters specified by the Regulation.
The documentation must also address additional foreseeable safety hazards and provide mitigation instructions for identified risks such as fire or explosion.
This is an important distinction from the general workplace position: Article 12 creates specific product-safety requirements for stationary BESS, but it is not a complete workplace storage specification for every loose, spare or charging lithium-ion battery.
No. A stationary Battery Energy Storage System, commonly referred to as BESS, is an integrated battery system designed to store electrical energy and later deliver it to the grid or an end user.
A workplace battery store may instead contain:
The legal and technical requirements applying to an integrated stationary BESS should therefore not automatically be transferred to every battery-storage room or cabinet.
The National Standards Authority of Ireland lists I.S. EN IEC 62485-5:2021, Safety requirements for secondary batteries and battery installations – Part 5: Safe operation of stationary lithium-ion batteries, as a current Irish Standard.
The standard applies to stationary lithium-ion battery installations and addresses safety measures associated with hazards including:
It also covers safety considerations relating to installation, use, inspection, maintenance, storage and environmental aspects.
The standard applies to stationary battery applications, including Battery Energy Storage Systems.
I.S. EN IEC 62485-5 is a technical standard rather than a standalone Irish workplace regulation.
The Government published the Electricity Storage Policy Framework for Ireland in July 2024.
It is Ireland’s first national policy framework specifically addressing electricity storage and sets out the role of storage in the electricity system through to 2040.
The framework deals primarily with front-of-meter electricity storage and addresses matters including:
It is an energy-policy framework rather than a detailed fire-safety specification for lithium-ion battery storage.
Businesses should therefore not treat the Electricity Storage Policy Framework as a substitute for workplace, fire, electrical or product-safety requirements.
Potentially. A new battery storage building, alteration to an existing building or other development may also involve requirements under Ireland’s Building Regulations and building-control system.
Part B of the Building Regulations addresses fire safety, with Technical Guidance Document B providing guidance on how the requirements can be achieved for buildings within its scope.
Depending on the project, planning permission, a Fire Safety Certificate or other building-control requirements may also need to be considered.
These requirements are separate from the employer’s workplace risk-assessment duties and from the product-safety requirements applying to batteries or BESS equipment.
Yes. Once a battery becomes waste, waste-management legislation and battery-specific obligations become relevant.
Regulation (EU) 2023/1542 now provides the overarching EU framework for batteries and waste batteries.
Ireland also has national waste-battery requirements, including the European Union (Batteries and Accumulators) Regulations 2014, as amended, which contain obligations concerning the collection, treatment, recycling and management of waste batteries.
Whether a battery is waste depends on the circumstances. Under waste legislation, an item becomes waste where its holder discards it, intends to discard it or is required to discard it.
The Environmental Protection Agency published Guidance on the Safe Storage of Lithium-Ion Batteries at Waste Handling Facilities in 2024.
The EPA produced the guidance because damaged or failing lithium-ion batteries can create a significant risk of fire and the release of hazardous substances.
The guidance applies specifically to rechargeable waste lithium-ion batteries handled at locations including:
It should not be interpreted as a statutory storage specification applying automatically to every business storing new or operational batteries.
The EPA recommends dedicated quarantine arrangements for damaged or leaking waste lithium-ion batteries.
For facilities within the scope of the guidance, quarantine areas should take account of measures including:
The EPA also recommends isolating damaged or leaking batteries from other battery waste and packaging them separately.
The EPA guidance recommends packaging batteries so that they are protected from short circuits and physical damage while in storage and transit.
Measures described in the guidance include:
The exact packaging requirements can also depend on the condition and transport classification of the battery.
Not automatically. The EPA document is specifically concerned with waste rechargeable lithium-ion batteries at waste handling facilities and collection points.
A manufacturer, warehouse, laboratory, data centre or other organisation storing new or operational batteries should not present every recommendation in the EPA waste guidance as a direct legal requirement for its own operation.
However, many of the underlying risk-control principles – such as preventing damage, isolating defective batteries, controlling heat and providing suitable emergency arrangements – can be relevant when completing a wider workplace risk assessment.
No. A battery cabinet, enclosure or storage building can form part of a site’s safety measures, but no single storage product makes the entire workplace automatically compliant with Irish or EU requirements.
The dutyholder may also need to address:
The appropriate measures should be determined from the battery inventory, activities and site-specific risks.
Chemstore designs and supplies lithium-ion battery storage, charging and emergency-response solutions for industrial, commercial, manufacturing, logistics, research and other workplace applications.
For larger battery inventories, the Electrovault lithium-ion battery storage range can be configured around the batteries and requirements identified through the site-specific risk assessment.
Depending on the specification, options can include:
For smaller batteries and charging applications, Chemstore also supplies lithium-ion battery storage and charging cabinets.
For damaged or defective batteries requiring controlled temporary containment, Chemstore provides lithium-ion battery storage and transport boxes.
The appropriate solution should be selected according to the battery chemistry, capacity, quantity, condition, charging arrangements, location and findings of the site-specific assessment.
A Chemstore product does not replace the employer’s or operator’s duties under workplace, fire, electrical, environmental or other applicable legislation.
