Introduction

Safeguard workplace from hidden fire hazards is the focus of this guide, which explains what risks modern technology brings and how responsible persons, facilities teams and managers can reduce them. You will learn to spot common ignition sources, update your fire risk assessment, introduce practical controls and set a clear plan for monitoring and response.

Why modern technology creates hidden fire hazards

Modern workplaces rely on batteries, chargers, servers and smart devices. Each item brings useful benefits, yet it also introduces new ignition sources. Lithium-ion batteries, for example, can enter thermal runaway after damage or poor charging. They may then produce intense heat and reignite after firefighting efforts. Evidence shows these events are an emerging risk across many sectors. For that reason, duty holders must factor electronic risks into their fire safety planning. nfcc.org.uk

Start by identifying the technological items in your building. Consider personal devices, e-bikes, fork-lift batteries, server racks and back-up power supplies. Next, think about how devices are charged, stored and disposed of. Small oversights — such as charging an e-scooter in a corridor — can create major hazards.

Update your fire risk assessment to include electronic risks

A suitable and sufficient fire risk assessment must capture ignition sources from technology and the controls to manage them. The law requires a written risk assessment where your organisation employs five or more people. You should review the assessment whenever changes occur, for example when new devices are introduced or a refurbishment is completed. gov.uk

Practical checklist for assessments

List all battery-powered and mains-powered equipment.

Note charging locations and storage areas.

Identify communal charging points and their supervision.

Check ventilation in rooms that contain battery stores or server cabinets.

Review past incidents or near-misses involving electronic equipment.

If you lack the in-house expertise, appoint a competent person or engage a consultant. Total Safe offers professional Fire Risk Assessment services that can be tailored to technology risks and compliance requirements. Fire Risk Assessment. totalsafeuk.com

Control measures: batteries, chargers and charging protocols

Control measures should be straightforward and enforceable. First, segregate charging locations from escape routes and combustible materials. Preferably place charging on hard, non-combustible surfaces with adequate ventilation. Second, only use manufacturer-approved chargers and approved spare batteries. Third, avoid overnight or unattended charging of personal mobility devices and prohibit charging in sleeping or high-occupancy areas.

For businesses that permit e-bikes or e-scooters on site, set rules on storage and charging. The National Fire Chiefs Council recommends not charging these devices in bedrooms or enclosed escape routes and highlights specific warning signs such as swelling, overheating or strange noises. Communicating these simple rules will reduce the risk of fire events. nfcc.org.uk

Electrical maintenance and inspection: a risk-based approach

Regular maintenance prevents many electrical fires. The Health and Safety Executive advises a risk-based approach to portable appliance testing and to inspecting electrical installations. User checks, formal visual inspections and scheduled testing should reflect the environment and equipment type. In low-risk office settings, user checks and periodic inspections often suffice. For harsher environments or frequent equipment movement, increase inspection frequency. hse.gov.uk

Key actions

Implement user checks for damage before use.

Schedule formal visual inspections for all portable equipment.

Carry out combined inspection and testing of installations at appropriate intervals.

Keep records of inspections and repairs.

Server rooms, UPS and battery rooms: targeted safeguards

Server rooms, UPS cabinets and dedicated battery stores require special controls. These areas concentrate energy storage and heat, so keep them well ventilated and free from combustible clutter. Install and commission detection systems suited to the risk, such as aspirating detectors or multi-sensor devices for early warning. Where batteries are stored in quantity, consider dedicated suppression systems and ensure staff know how to isolate power safely.

Additionally, follow manufacturer guidance for battery racking and spacing. Place clear signage and maintain segregation between battery types. Regularly inspect terminals, enclosures and ventilation to spot corrosion or heat damage early. NFCC and industry guidance stress that batteries can reignite even after extinguishing, so monitor these areas closely. nfcc.org.uk

Safe disposal, recycling and segregation of electronic waste

Incorrect disposal of batteries and electrical items drives fires in waste streams and bin lorries. NFCC campaigns emphasise the risk posed when batteries are crushed in recycling centres. To reduce risk, store waste electrical items separately in secure, ventilated containers and use specialist recycling services. Educate staff about not disposing of lithium batteries in general waste and provide clear collection points. nfcc.org.uk

Practical steps include

Provide labelled battery bins and secure e-waste containers.

Use licensed waste contractors for electronic disposal.

Train cleaning and waste-handling staff on identifying batteries hidden within devices.

Introduce a small quantity quarantine area for damaged or suspect batteries.

Emergency response planning and training for electronic fires

Prepare for an electronic fire with a realistic emergency plan. Include specific procedures for battery-related incidents, such as how to raise the alarm, what to do if a device is smoking and how to isolate power sources. Ensure that evacuation routes remain clear and that staff know assembly points.

Train staff to recognise early signs of battery failure: heat, swelling, hissing sounds or unusual smells. Carry out regular drills that include simulated device fires so staff practice safe evacuation and notification. In some cases, provide fire blankets and appropriate extinguishers, but emphasise that large battery fires can need specialist intervention from the fire service.

Where technologies like server UPS systems are present, coordinate with local fire and rescue services so they understand the risks and building layout. This liaison helps when a fire involves complex energy systems or potential re-ignition.

Procurement and lifecycle controls for reducing long-term risks

Reduce risks at the procurement stage. Buy equipment from reputable suppliers and choose devices with robust safety certifications. For batteries, prefer units that conform to recognised standards and have clear manufacturer support for spares and warranty handling.

Maintain an asset register for all high-risk items such as forklifts, e-bikes, UPS units and large battery banks. Track age, service history and end-of-life dates. Replace ageing batteries before they become a failure risk. Lifecycle management also helps when demonstrating due diligence during audits or enforcement visits.

Monitoring, record-keeping and continuous improvement

Good record-keeping proves you have acted reasonably to manage technology-related hazards. Maintain logs for:

Fire risk assessment updates.

Electrical inspection and PAT results.

Battery purchases, storage and disposal records.

Staff training and drill attendance.

Review these records during scheduled audits and after any incident. Use lessons learned to update policies and controls. Regular review demonstrates a commitment to safety and helps meet your legal obligations under the Fire Safety Order.

Practical examples and quick wins

Here are simple actions that quickly reduce risk:

Ban charging of personal e-bikes or e-scooters in corridors and stairwells.

Provide dedicated, ventilated charging rooms with supervision policies.

Introduce a policy requiring manufacturer-approved chargers only.

Add extra detection coverage where many chargers are used.

Offer short awareness sessions for staff on battery hazards.

These measures are inexpensive and effective. They also show inspectors and insurers that you are actively managing modern fire hazards.

When to call a specialist

Call a specialist if:

You have significant battery storage or multiple high-capacity batteries.

You plan to install or modify server or UPS systems.

You cannot identify all ignition sources during a risk assessment.

An incident occurs where thermal runaway or re-ignition is suspected.

Total Safe can provide tailored audits, fire strategy advice and mitigation planning for complex technology risks. Engaging a consultant early often saves time and reduces long-term cost. Fire Safety Services. totalsafeuk.com
