From Spark to Shutdown, What Shop Fires Are Teaching Us About Modern Fire Risks

What Shop Fires Are Teaching Us About Modern Fire Risks

In retail, fire risk rarely announces itself. It does not arrive with sirens or warning signs, it begins quietly. A charger left plugged in, a device placed on a counter, a battery reaching the end of its life cycle. On the surface, nothing out of the ordinary. Yet recent events, including widely shared footage from a Glasgow city centre fire, have highlighted just how quickly a seemingly minor incident can escalate into something far more serious.

At the centre of that incident was a factor now common across high streets everywhere, lithium batteries.

Over the past decade, lithium batteries have become embedded in the day to day operations of retail environments. From vape products and cordless tools to e-bikes, scooters and mobility aids, they’re now part of infrastructure and services many shops rely on. Their compact, efficient and powerful, but their risks are far greater.

Unlike conventional electrical fires, lithium battery fires behave in a fundamentally different way. Once a battery enters thermal runaway, it begins to generate its own heat and sustain combustion without relying on external oxygen. This means that even when a fire appears to have been suppressed, it can reignite unexpectedly, sometimes minutes or even hours later. For firefighters, this presents a complex challenge. For shop owners and property managers, it introduces a level of unpredictability that traditional fire safety planning does not always account for.

Early footage of the Glasgow fire incident suggests that what began as a contained fire rapidly intensified, producing dense smoke, aggressive flames and a level of heat that was unmanageable.

For many shop owners, the assumption has long been that fire risk is primarily structural, wiring, heating systems, or cooking equipment in certain premises. While these remain important considerations, the rise of lithium powered devices has shifted fire risk. A single faulty battery, particularly if charging or stored incorrectly, can now act as the ignition point for a large scale fire to erupt.

For fire prevention, it is essential to store lithium products in fire safe units. For fire impact prevention within a business setting, the consequences are far greater than just the damage of a premises. Critical business assets, financial records, legal documents, digital storage devices and high value stock are also vulnerable. This is where fire resistant storage becomes part of a broader resilience strategy rather than an afterthought. Products from brands such as Phoenix Safes are engineered to withstand extreme temperatures for sustained periods, these safes provide a controlled internal environment that protects contents even as external conditions deteriorate.

This means that while a fire may disrupt operations, it does not have to erase the essential components needed to rebuild. Documents remain intact, data is preserved and key assets are secured against both fire and subsequent risks such as water damage or unauthorised access during recovery.

A professionally conducted fire risk assessment should therefore go beyond identifying ignition sources. It should consider how modern risks, including lithium batteries, interact with the physical layout of the premises, how they are managed operationally and how assets are protected in a worst case scenario.

The reality is that shop fires are no longer defined solely by traditional hazards. As technology evolves, so should the approach to safety. The Glasgow incident is not an isolated incident, it is part of a broader pattern across the retail sector.
