Most workplace fires are preventable.
Fires start when fuel, heat and oxygen come together. In most workplaces that means an ignition source - a faulty appliance, a hot works spark, a discarded cigarette - meeting fuel that was left where it should not be, such as waste, packaging or flammable liquids. Take the heat away from the fuel and most fires never start.
The good news is that fire prevention is largely about everyday habits. With proper Fire Marshal Training, staff learn to recognise the ignition sources and fuels around them and to apply simple controls: tidy as you go, keep flammables stored properly, manage electrics and hot works, and keep escape routes clear.
This guide explains the common causes of workplace fires, the practical measures that prevent them, and how good housekeeping, electrical safety and hot works control work together to keep premises safe.
What actually causes workplace fires
Understanding the causes helps you take preventive action today. These ignition sources and fuels drive most fires in UK workplaces.
Faulty electrics
Damaged cables, overloaded sockets and poorly maintained equipment are a leading cause of fire. Most are caught by simple visual checks.
Hot works
Cutting, welding and grinding throw sparks and heat. Without a permit and a fire watch, they can ignite nearby fuel hours later.
Combustible waste
Paper, packaging, pallets and offcuts left to pile up give a fire plenty to feed on, and often sit close to ignition sources.
Smoking and naked flames
Discarded cigarettes, lighters and candles still start fires. Designated areas and proper disposal keep ignition away from fuel.
Cooking and kitchens
Hot oils, unattended hobs and grease build-up cause many fires. Kitchens need their own controls and wet chemical extinguishers.
Flammable storage
Solvents, gases, aerosols and chemicals stored badly or near heat are a serious risk. Safe storage keeps fuel away from ignition.
Battery charging
Forklift, tool and device batteries can overheat or fail. Charging in the wrong place, or overnight unattended, raises the risk.
Arson and security
Deliberate fires often start with waste or materials left accessible outside. Good security and tidy external areas reduce the risk.
How to prevent fires: control the heat, manage the fuel.
Fire prevention is a set of everyday habits. Keep ignition sources away from anything that burns and most fires never get the chance to start.
Good housekeeping
Tidy as you go, empty bins, clear packaging and offcuts, and never let waste pile up near heat sources. Less fuel means less fire.
Electrical safety
Avoid overloaded sockets and daisy-chained extension leads, report damaged cables and plugs, and keep equipment maintained and switched off when not in use.
Control hot works
Use a hot works permit for cutting, welding and grinding. Clear combustibles, keep an extinguisher to hand and run a fire watch during and after the task.
Safe storage of flammables
Store solvents, gases, aerosols and chemicals in suitable, ventilated places away from ignition sources, and keep only what you need on the floor.
Manage smoking and cooking
Provide designated smoking areas with proper disposal, never leave cooking unattended, and keep kitchen surfaces and extraction free of grease.
Safe battery charging
Charge batteries and devices in designated areas, on the right charger, and avoid leaving them charging unattended overnight.
Keep escape routes clear
Never block or wedge open fire doors, never store anything in corridors and stairwells, and make sure exits and signage stay clear at all times.
Maintain detection and alarms
Test fire alarms regularly, keep detectors and extinguishers serviced, and act on faults quickly so an alarm always reaches everyone in time.
Why good housekeeping does most of the work.
Housekeeping is the simplest and most effective fire prevention measure there is. A workplace with little loose waste, properly stored flammables and clear floors gives a fire almost nothing to feed on, so even an ignition source struggles to take hold.
It costs nothing but attention, and it protects everyone in the building. Tidy bays, emptied bins, sealed flammable stores and clear escape routes remove the fuel that turns a spark into a serious fire.
- Clear waste and packaging as you go
- Store flammables in proper, ventilated places
- Keep bins emptied and away from buildings
- Keep escape routes and fire doors clear
- Make tidying part of every shift
Electrical safety and hot works: managing the ignition.
If housekeeping removes the fuel, controlling ignition sources removes the spark. Electrical faults and hot works are two of the most common causes of workplace fire, and both are highly preventable with simple controls.
For electrics, avoid overloaded sockets, report damaged equipment and keep appliances maintained. For hot works, use a permit, clear the area of combustibles, keep an extinguisher to hand and maintain a fire watch after the task finishes, because smouldering can ignite hours later.
- Switch off and unplug equipment not in use
- Use a permit and fire watch for hot works
- Report faults and damage straight away
How fire prevention works in practice
Fire prevention comes down to the fire triangle: fuel, heat and oxygen. Take any one away and a fire cannot start. Since oxygen is all around us, prevention focuses on keeping ignition sources (heat) apart from anything that burns (fuel). Every practical measure, from emptying a bin to running a hot works permit, is really doing one of those two jobs.
Remove the fuel: housekeeping that works
- Clear waste daily - paper, packaging, pallets and offcuts removed before they build up.
- Store flammables safely - solvents, gases and aerosols kept in proper, ventilated stores away from heat.
- Keep only what you need - minimise the combustible materials kept on the work floor.
- Manage bins and skips - emptied regularly and positioned away from the building.
The most effective fire prevention measure in the world is the pile of waste you clear before a stray spark ever reaches it.
Control the heat: ignition sources
Where fuel cannot be fully removed, the focus shifts to controlling ignition:
- Electrical safety - no overloaded sockets, no damaged cables, equipment maintained and switched off when not needed.
- Hot works permits - documented controls, cleared areas, extinguishers to hand and a fire watch during and after the task.
- Smoking control - designated areas with proper disposal, well away from buildings and stored materials.
- Cooking and kitchens - never leave cooking unattended, keep extraction clean and provide the right extinguishers.
- Battery charging - charge in designated areas, on the correct charger, and avoid leaving items charging unattended overnight.
Detection, escape and the responsible person
Prevention reduces the chance of a fire, but you still need to detect one early and get everyone out. Fire alarms and detection must be maintained and tested, escape routes and fire doors kept clear, and extinguishers serviced. The fire risk assessment, which decides what each building needs, remains the duty of the responsible person, usually the employer or building occupier.
Protecting people if a fire starts
Even the best prevention cannot guarantee a fire-free workplace, so a clear plan matters. Everyone should know how to raise the alarm, where the escape routes and assembly point are, and who the fire marshals are. Clear, unobstructed exits and a calm, rehearsed evacuation turn a frightening event into a safe one.
The role of Fire Marshal Training
Fire Marshal Training is not just good practice, it is how staff learn to spot risks and prevent fires automatically. Proper awareness training teaches:
- How fires start, using the fire triangle of fuel, heat and oxygen
- The common ignition sources and fuels in your workplace
- Everyday prevention habits: housekeeping, electrics, hot works and storage
- How to keep escape routes and fire doors clear
- What to do if a fire breaks out, including raising the alarm and evacuation
Our online Fire Marshal Course covers all of these topics in approximately 45 minutes. You can complete it from any device and receive your certificate instantly on passing. It is awareness training that supports Fire Safety Order 2005 compliance - hands-on practice with live extinguishers may also be needed for some roles, and the fire risk assessment remains the responsible person's duty.
