Ensure lithium-ion battery safety with engineered ventilation. Learn why proper airflow and cooling are critical for battery storage risk management
A Growing Risk Hiding in Plain Sight
The recent fire at a vape shop in Glasgow should be a wake-up call for any business storing lithium-ion batteries.
What initially appeared to be a localised retail incident quickly escalated into a major emergency response, with extensive damage to property and disruption to the surrounding area. While investigations continue, the likely involvement of lithium-ion batteries highlights a growing and often underestimated risk.
This isn’t just a fire safety issue anymore. It’s an engineering one.
Across the UK, lithium-ion batteries are now embedded in everyday operations:
- Vape retail and distribution
- E-bike and e-scooter storage
- Consumer electronics warehousing
- Backup power and energy systems
Yet many of these environments are still treated as standard storage spaces, not the high-risk zones they can quickly become.
The core challenge lies in thermal runaway – a failure mode capable of generating extreme heat, flammable gases, and rapid fire spread.
And critically, it doesn’t always start with flames.
The Gap Between Guidance and Reality
Current UK guidance is clear in principle:
But in practice, “well-ventilated” is rarely defined – and even more rarely, engineered.
Too often, businesses rely on:
- Comfort cooling systems not designed for hazard scenarios and management
- Natural ventilation with no performance validation
- Shared HVAC systems that can spread smoke or gases
- Backup power and energy systems
The result?
A hidden vulnerability that only becomes visible when something goes wrong.
Why Ventilation Is the First Line of Defence
When it comes to lithium-ion battery storage, ventilation isn’t a secondary consideration – It’s fundamental.
1. Temperature Control Reduces Failure Risk
Elevated ambient temperatures accelerate battery degradation and increase the likelihood of failure. Without controlled cooling, risk builds silently over time.
2. Gas Management Prevents Escalation
Failing batteries can release flammable gases before ignition. In confined or poorly ventilated spaces, these gases can accumulate to dangerous levels.
3. Smoke Control Protects People and Property
In a fire scenario, lithium batteries produce dense, toxic smoke and extreme heat. Without effective extract systems, evacuation, firefighting, and containment become significantly more difficult.
The Shift: From Compliance to Engineered Solutions
Forward-thinking organisations are starting to move beyond basic compliance and towards purpose-designed battery storage environments.
These typically include:
- Dedicated, segregated storage areas
- Independent ventilation systems with smart controls
- Active temperature control with redundancy
- Sensor-driven airflow response
- Integration with fire detection and suppression systems
This is where HVAC design moves from a background utility to a critical safety system.
Why This Matters Now
Incidents like the one in Glasgow are increasing scrutiny from:
- Fire authorities
- Insurers
- Regulators
At the same time, battery volumes are only going in one direction – that is up.
This combination is creating a clear divide between:
- Organisations proactively managing risk
- And those exposed to potentially severe operational and financial consequences
In workplaces and non-domestic premises, fire safety is covered under the Regulatory Reform (Fire Safety) Order 2005. This places a legal duty on a designated ‘Responsible Person’ to conduct appropriate audits which includes the risks associated with lithium-ion batteries1.
Where Specialist Expertise Makes the Difference
Designing ventilation for battery storage isn’t the same as designing for comfort or general industrial use.
It requires an understanding of:
- Thermal load under both normal and failure conditions
- Gas behaviour and dilution requirements
- Fire and smoke dynamics
This is exactly where Inergy Group is supporting clients across the UK delivering compliant solutions backed by the British Safety Council3.
By combining HVAC engineering expertise with real-world risk understanding, Inergy Group is supporting businesses:
- Identify hidden vulnerabilities in existing environments
- Design compliant, future-ready storage solutions
- Deliver systems that actively reduce risk – not just manage it
Final Thoughts
Battery storage risk is evolving faster than many buildings are.
The Glasgow incident won’t be the last – but it should be the moment the industry rethinks its approach.
Because in this context, ventilation isn’t optional.
It’s the control that can make the difference between a contained issue and a major incident.
Start your Project with us
If your business stores or handles lithium-ion batteries, now is the time to ask a simple question:
Would your current environment stand up to a failure event?
If the answer isn’t clear, it’s worth a conversation.
