Most people never think about fire at work until the alarm goes — and by then it's too late to start learning. This guide keeps things simple: how fire works, where it tends to start, and the calm, clear steps that get everyone out safely.
The three things every fire needs
Fire is simpler than it seems. It needs heat, fuel and oxygen together. Remove any one and it stops. That's the whole basis of fire safety.
Get that, and everything from a tidy workshop to the right extinguisher makes sense.
Where fires usually start
A handful of everyday things cause most workplace fires. Tap each to see how to keep on top of it.
The spark
Faulty wiring, hot works, heaters, cooking and smoking are the usual starters. Control them first.
The fire triangle
Heat, fuel, oxygen. Take one away and the fire can't burn — that's the idea behind every control.
Heat
Ignition sources — flames, sparks, hot surfaces, electrical faults. Remove the heat, no fire.
Fuel
Anything combustible — paper, wood, fabrics, liquids, gases, even fine dust.
Oxygen
Always around us. Smothering or starving a fire of oxygen is how many extinguishers work.
Alarm sounds? Out you go — and stay out. Nothing in the building is worth your life.
The four steps
Prevent, detect, escape, and only fight if it's safe:
Prevent it
Control ignition sources, store flammables safely, and keep waste and clutter down.
Detect it early
Working alarms and detectors, tested regularly, buy the minutes that save lives.
Get out
On the alarm, leave by the nearest safe exit, go to the assembly point — don't go back for belongings.
Fight it only if safe
Small, contained fire and a clear escape behind you? The right extinguisher may help. If in doubt, get out.
What the law says
Under the Safety, Health and Welfare at Work Act 2005 and the Fire Services Acts 1981 & 2003employers must manage fire risk and protect everyone on the premises. In practice that means:
- Carry out a fire risk assessment
- Provide and maintain alarms, signs and extinguishers
- Keep escape routes clear and clearly marked
- Train staff and run evacuation drills
