Modern offices run on lithium-ion batteries.
Laptops, smartphones, tablets, wireless keyboards, power banks, handheld scanners, spare devices, and backup batteries are now part of daily business operations. In many Singapore workplaces, these devices are charged at desks, in meeting rooms, inside IT cupboards, at shared pantry counters, and sometimes overnight when nobody is around to notice early warning signs.
That is why office fire safety should no longer be limited to only the old risks. Standard workplace fire protection remains important, but companies should also review whether their offices are prepared for lithium-ion battery fire risks.
Why Office Charging Habits Matter
Lithium-ion batteries are common because they are compact, rechargeable, and powerful. They also need to be treated with care.
A battery may become unsafe if it is damaged, exposed to heat, charged with unsuitable equipment, stored badly, or kept in use after it starts showing signs of failure. Warning signs can include unusual heat, swelling, smoke, vapour, hissing sounds, leakage, or a strange chemical smell.
In an office, the concern is not only the device itself. The concern is the environment around it.
A laptop charging under paper, a power bank left in a drawer, multiple devices connected to one power strip, or spare batteries stacked in a warm IT cupboard can turn a small equipment issue into a workplace emergency.
Common Office Battery Fire Risk Areas
1. Desks With Overnight Charging
Many employees leave laptops, phones, earbuds, and power banks charging at their desks after work.
If a device fails during office hours, someone may notice the heat, smell, smoke, or sound early. If the same failure happens at night or over the weekend, the response may be delayed.
Workplaces should consider a simple end-of-day charging policy: unplug non-essential chargers, avoid charging devices on soft or cluttered surfaces, and keep charging areas visible and ventilated.
2. Shared Breakrooms and Pantry Areas
Staff breakrooms often become informal charging stations. Phones, personal fans, tablets, and power banks may be charged near kettles, coffee machines, microwaves, and liquids.
This creates several problems at once: heat, moisture, high-power appliances, and crowded sockets.
A breakroom safety check should ask:
- Are chargers kept away from heat sources and liquids?
- Are power strips overloaded or daisy-chained?
- Is the walkway clear?
- Is fire-safety equipment accessible?
3. IT Rooms, Storage Cupboards, and Spare Battery Areas
Old laptops, retired power banks, spare phones, and backup batteries are often stored out of sight.
That does not make them risk-free.
Lithium-ion batteries can still pose fire risks when they are not in active use, especially if they are damaged, swollen, poorly ventilated, or stored in dense stacks. IT teams and office managers should regularly inspect stored devices and remove damaged batteries through proper disposal channels.
4. Co-working Spaces and Multi-Tenant Offices
In a co-working space or office tower, fire safety is shared. One tenant's charging habits can affect other occupants on the same floor or in the same building.
This is especially important in high-density Singapore workspaces, where people, equipment, exits, and shared facilities are close together.
Practical Office Charging Safety Checklist
Use this checklist for offices, co-working spaces, retail back offices, workshops, and staff areas:
- Unplug non-essential chargers before leaving for the day.
- Do not charge power banks, laptops, or phones under paper, fabric, or other clutter.
- Avoid daisy-chaining power strips.
- Keep chargers away from heat sources and liquids.
- Stop using batteries that are swollen, leaking, unusually hot, or damaged.
- Do not puncture, press, crush, or charge a damaged battery.
- Keep escape routes and fire exits clear.
- Store spare devices and batteries in a cool, dry, visible, and ventilated area.
- Review whether fire extinguishers are accessible and suitable for the risks present.
- Train staff to step back and alert others if a battery starts smoking, swelling, hissing, or emitting a strange smell.
Standard Fire Extinguishers Still Matter, But Battery Risks Need Separate Attention
Every office still needs proper fire protection for common workplace fire risks.
However, lithium-ion battery fire risks should be considered separately because battery failures can involve thermal runaway, intense heat, vapour, and re-ignition risk.
For Singapore businesses, this means fire-safety planning should reflect how people actually work today: with rechargeable devices everywhere.
COMBAT's Lithium-Ion Battery Fire Extinguisher for Modern Workplaces
COMBAT Brand Fire supplies the Combat 6L Fluorine-Free Lithium-Ion Battery Fire Extinguisher for environments where lithium-ion batteries are part of daily life.
The extinguisher is purpose-designed for modern battery fire risks and is tested on lithium-ion battery fires up to 600Wh under the NTA 8133:2021 test method.
It is suitable for Class A, B, C, F fire risks and lithium-ion battery fire risks, dielectric tested up to 1000V, and uses a fluorine-free formula.
For offices, IT rooms, co-working spaces, retail backrooms, workshops, and charging areas, it can form part of a more relevant fire-safety plan for today's battery-powered workplace.

Key Takeaway for Singapore Workplaces
Your workplace does not need to be high-risk to be worth reviewing.
If your office has laptops, phones, tablets, power banks, spare batteries, charging stations, or IT storage, it already has lithium-ion batteries in daily use.
Good fire safety starts with simple habits: cleaner charging areas, better storage, clear exits, accessible equipment, and a fire extinguisher strategy that matches the risks in the room.
FAQ: Office Charging Safety and Lithium-Ion Battery Fire Risks
Are lithium-ion batteries common in offices?
Yes. Most modern offices use lithium-ion batteries every day in laptops, smartphones, tablets, power banks, wireless devices, and backup equipment.
Is overnight office charging unsafe?
Overnight charging is common, but it increases risk because a battery failure may go unnoticed when the office is empty. Workplaces should avoid unnecessary overnight charging and keep charging areas clear, visible, and ventilated.
What are warning signs of a failing lithium-ion battery?
Warning signs include swelling, unusual heat, smoke, vapour, hissing sounds, leakage, or a strange chemical smell. If these signs appear, stop using the device and do not charge, puncture, crush, or press on the battery.
Do standard fire extinguishers cover every office fire risk?
Standard fire extinguishers remain important for common office fire risks. Lithium-ion battery fire risks should be reviewed separately because battery failures can involve thermal runaway and re-ignition risk.
What fire extinguisher should offices consider for lithium-ion battery fire risks?
Offices that use many rechargeable devices should consider a fire extinguisher purpose-designed for lithium-ion battery fire risks, such as the Combat 6L Fluorine-Free Lithium-Ion Battery Fire Extinguisher.
Where should offices place lithium-ion battery fire extinguishers?
Placement depends on each workplace layout and risk assessment, but common review areas include IT rooms, charging stations, staff breakrooms, storage cupboards, workshops, retail backrooms, and office floors with high device density.
